The average cost of a healthcare data breach reached $10.1 million in 2024, the highest of any industry for the 14th consecutive year, according to the

Formerly known as Agenda, Qilin has pivoted its operations to focus on high-stakes targets in the medical and public health sectors. This year, Qilin has emerged as a primary threat to healthcare infrastructure due to its adoption of the Rust programming language for its encryption payloads.

The group gained global notoriety following the 2024 attack on Synnovis, which severely disrupted pathology services for the National Health Service (NHS). Qilin’s strategy relies on double extortion, where sensitive patient data is exfiltrated before encryption to provide the attackers with additional leverage during negotiations. 

Below, we’ve got an overview of Qilin’s tactics. If you’ve lost data due to a ransomware incident, we’re here to help: Datarecovery.com provides ransomware disaster recovery services for organizations of all sizes, including healthcare providers. Call 1-800-237-4200 or submit a case online to get started. 

Technical Analysis: Qilin Attack Vectors and Techniques

Qilin’s transition from Go (Golang) to Rust provides the bad actors with a significant technical advantage. 

Rust is a memory-safe language that offers high performance and easier cross-platform compilation, allowing the ransomware to target Windows, Linux, and VMware ESXi environments with the same codebase. The current “Qilin.B” variant uses a combination of AES-256-CTR and ChaCha20 encryption. 

To maximize speed and avoid detection by endpoint detection and response (EDR) systems, the ransomware employs intermittent encryption, where it encrypts only every few blocks of data rather than the entire file. Intermittent encryption tends to be good news for data recovery teams, but the nature of the targeted data certainly matters. 

The group’s primary attack vectors often involve the exploitation of vulnerabilities in edge-facing hardware and remote access services:

• Credential Harvesting: Qilin affiliates frequently use specialized infostealers to extract credentials from browsers. 
• Vulnerability Exploitation: The group targets unpatched vulnerabilities in VPNs and firewalls, such as those documented in CISA’s advisory on Qilin tactics.
• Living-off-the-Land (LotL): Once initial access is gained, the attackers use legitimate administrative tools like PowerShell and PsExec to deploy the ransomware payload and disable backup services.

What to Do if You Suspect a Qilin Infection

If your organization experiences a sudden loss of file access or discovers unauthorized administrative activity, immediate action is required to prevent further spread.

Common indicators of a Qilin infection include:

• File Extensions: Encrypted files are typically appended with a randomized alpha-numeric extension (e.g., .MmXReVIxLV) or, in some cases, the .qilin extension.
• Ransom: Look for a text file named [ID]_readme.txt or RECOVER-[ID]-FILES.txt. The note usually contains a link to a Tor-based victim portal and may include threats to release patient data on the Qilin leak site if the demand is not met.
• System Indicators: Qilin systematically deletes Volume Shadow Copies and clears Windows Event Logs to hinder local forensic analysis.

If these indicators are present, isolate the affected systems by disconnecting them from the network — do not shut them downs. Contact us immediately at 1-800-237-4200. Attempting to use free decryptors or unverified tools can lead to permanent data corruption, especially when dealing with the complex RAID and server architectures common in healthcare environments.

In this guide, we’ll explore five attack vectors, along with defense tactics to limit exposure. If your organization is currently facing a ransomware attack, we recommend seeking professional assistance immediately. Contact our team at 1-800-237-4200 to discuss options or set up a case online.

1. Phishing and Social Engineering

Phishing remains the most prevalent method for delivering ransomware because it targets the most unpredictable element of any security chain: humans. 

Attackers send deceptive emails that appear to be from trusted sources — such as a bank, a well-known vendor, or an internal department — to trick employees into clicking a malicious link or opening an infected attachment. 

Once a user interacts with the message or clicks the link, a downloader (or dropper) is executed on the machine.

Strategic Defense Against Phishing

The first line of defense here is a robust email filter. Regular security awareness training is also key: Employees need to know how to recognize suspicious requests before they engage with them. We also suggest configuring email clients to block macros (small programs used to automate tasks in documents) by default, as these are frequently used to hide malicious scripts.

2. Exploiting Remote Desktop Protocol (RDP)

Remote Desktop Protocol (RDP) allows administrators and employees to access computers from remote locations. While convenient, RDP is a favorite target for ransomware groups because many organizations leave RDP ports (typically port 3389, but not exclusively) open to the internet without adequate protection.

Cybercriminals use brute-force tools to systematically guess passwords until they find a match. Once they gain access, they can manually disable antivirus software, delete local backups, and execute the ransomware. Our engineers frequently see cases where attackers spend days or weeks inside a network after an RDP breach, carefully mapping out the environment (and in some cases, ensuring that payloads are present on all air-gapped backups) before finally triggering the encryption.

Strategic Defense Against RDP Exploits

Exposing RDP directly to the public internet creates an unnecessary and significant risk. Instead, require the use of a Virtual Private Network (VPN) with Multi-Factor Authentication (MFA) to access remote systems. Limiting login attempts and using complex, unique passwords across all accounts will also significantly lower the risk of a successful brute-force attack. 

For a comprehensive look at securing these entry points, the CISA #StopRansomware Guide offers excellent technical frameworks.

3. Unpatched Software Vulnerabilities

Software developers regularly release security patches to fix bugs or vulnerabilities that hackers could exploit. When an organization fails to apply these updates promptly, they leave a door open for ransomware. These attacks often target common applications like browsers, operating systems, or server-side software.

In some instances, attackers utilize Zero-Day exploits (vulnerabilities that are not yet known to the software vendor). These are harder to defend against, but the vast majority of ransomware events we analyze involve exploits for which a patch had already been available for months.

Strategic Defense Against Software Vulnerabilities

Establishing a rigorous patch management policy ensures that critical updates are not overlooked. Prioritize updates for internet-facing systems and infrastructure that handles sensitive data. Organizations should consult the documentation for their specific operating system or server software to automate these updates where possible.

4. Compromised Credentials and Credential Stuffing

Attackers often obtain usernames and passwords from previous data breaches at other companies. Because people frequently reuse the same password across multiple platforms, a leak at one service provider can provide the keys to a corporate network. 

Credential stuffing (using lists of leaked credentials to automate logins) allows ransomware operators to walk through the front door without needing to write a single line of malicious code.

Strategic Defense Against Credential Theft

Enforcing the use of a password manager ensures that employees use unique, high-entropy passwords for every service. More importantly, deploy Multi-Factor Authentication (MFA) across the entire enterprise — MFA renders those stolen credentials useless.

5. Drive-By Downloads and Malvertising

A drive-by download occurs when a user visits a legitimate but compromised website, and malware is automatically downloaded to their device without their knowledge or consent. 

Similarly, malvertising involves injecting malicious code into digital ads. Ads might be hosted on reputable sites, which obviously complicates your defense strategy.

Strategic Defense Against Malicious Downloads

Modern web browsers feature built-in security protections that should be kept updated at all times. We also recommend using ad-blocking software and web-filtering tools to prevent connections to known malicious domains. Restricting administrative privileges on standard user accounts can also prevent malware from installing itself even if a download is initiated.

The post 5 Common Ransomware Attack Vectors appeared first on Datarecovery.com.

When an infection occurs, the first step is to name the threat. Identifying the variant can reveal which vulnerabilities were likely exploited, available decryption options, and the extent of the attack (whether data was exfiltrated and so on).

At Datarecovery.com, we help organizations recover from ransomware attacks. If you’re currently facing an active infection, call us at 1-800-237-4200 to speak with an expert or set up a case online.

Below, we’ll outline the steps you should take to identify a ransomware variant. Note that this isn’t a perfect list — we’ve seen sophisticated attackers mimic the methods of other ransomware gangs, so for a positive ID, you may need to work with an experienced ransomware recovery provider.

1. Analyze the File Extensions

Most ransomware variants rename your files after encryption by adding a specific string of characters to the end of the filename. While some modern variants use randomized extensions to evade simple detection, many prominent groups continue to use consistent markers:

• .akira: This extension is the hallmark of Akira ransomware, which emerged in early 2023 and claimed approximately $244 million in proceeds by late 2025. It’s still an active variant, despite efforts from CISA.
• .cactus: A common marker for Cactus ransomware, which frequently targets vulnerable VPNs.
• .play: Used by the Play ransomware group, which has increasingly leveraged supply chain gaps and unpatched external services in 2025.
• .lockbit: Associated with the LockBit family, a long-standing Ransomware-as-a-Service (RaaS) operation that remains active despite law enforcement disruptions.
• .locked: Often seen in mobile-based attacks like DroidLock, which blocks user access to the device screen rather than encrypting underlying files.

This is a small subset of known file extensions; since the file extensions are meaningless other than as a marker, they can be virtually anything. Write down any file extensions that indicate ransomware infection, then disconnect the infected machines ASAP. 

2. Examine the Ransom Note 

A previous Locky version ransomware message

Extensions may be randomized, but most variants also contain a ransom note that provides a clear indication of the attacker. These files are typically dropped into every encrypted directory and might be named something like README.txt, DECRYPT_FILES.html, or RESTORE_FILES.txt.

The visual style of the note and the payment portal can be diagnostic. For example, Akira’s portals are known for a distinct retro green-on-black aesthetic. Groups like ALPHV (BlackCat) often use more corporate-style negotiation panels and may include threats of Distributed Denial-of-Service (DDoS) attacks as part of a triple-extortion strategy. 

Most notes also include a victim ID, which specialists use to determine if a specific decryption key can be recovered from volatile memory or previously known leaks.

3. Identify Indicators of Compromise (IOCs)

Forensic experts look for Indicators of Compromise (IOCs), which are artifacts such as specific IP addresses, registry keys, or malicious scripts.

Akira threat actors, for instance, are notorious for abusing remote access tools like AnyDesk and exploiting specific vulnerabilities such as CVE-2024-40766 in SonicWall products for initial access. 

If your VMware ESXi virtual machines were targeted, it points toward sophisticated variants like Akira or BlackCat, which have specialized Linux versions designed to encrypt hypervisors. Other variants may use “use-after-free” flaws like CVE-2024-1086 to gain root control over Linux servers.

4. Preserve Critical Forensic Logs

To accurately identify a variant and close the security hole, you must preserve logs before they are overwritten or deleted by the malware’s cleanup scripts. In 2025, data exfiltration occurs in roughly 76% of ransomware incidents, making these logs vital for breach notification compliance. 

Ensure your team captures:

• Windows Event Logs: Look for service installations (Event ID 7045) or the clearing of security logs, which indicates an attempt to hide tracks.
• Firewall and VPN Logs: These can reveal the attacker’s point of entry and the IP addresses used for command-and-control (C2) communication.
• PowerShell History: Many variants use obfuscated PowerShell commands to move laterally across the network or disable antivirus software.
• MFT and NTFS Journaling: Analyzing the Master File Table (MFT) helps determine the exact second encryption began and which files were modified first.

Professional Support for Ransomware Identification and Recovery

The post Ransomware Identification: How to Determine Which Variant Has Hit Your Network appeared first on Datarecovery.com.

Akira is a sophisticated, human-operated Ransomware-as-a-Service (RaaS) operation that targets both Windows and Linux systems. It frequently exploits vulnerabilities in Virtual Private Networks (VPNs) to encrypt critical data and exfiltrate sensitive files for double extortion. 

If you have discovered files with the .akira extension or are locked out of your VMware ESXi virtual machines, your organization is the victim of a targeted attack. Disconnect the affected systems as soon as possible.

Below, we’ll explain how this specific ransomware variant operates, the technical vulnerabilities it exploits, and steps to maximize your chances of recovery. To discuss options with an expert, call 1-800-237-4200 or submit a case online.

Akira Ransomware: An Overview

First detected in March 2023, Akira has rapidly become one of the most active ransomware groups globally. Unlike automated spray-and-pray malware (where the objective is to infect as many potential victims as possible), Akira attacks are hands-on. The attackers may gain access to a network days or weeks before deploying the encryption payload, using that time to steal data and disable backups.

In cases we’ve handled, we’ve noted that Akira’s payment portals and ransom notes often feature a distinct green-text-on-black-background aesthetic. 

Technical Features of Akira Ransomware

To defend against or recover from Akira, it is helpful to understand exactly how it functions. Security researchers, including the FBI and CISA, have analyzed the malware’s code and identified several key characteristics.

Akira Encryption and Code Origins

Akira uses a hybrid encryption approach, which allows for faster encryption. It typically employs ChaCha20 (a high-speed stream cipher) to encrypt files and RSA to encrypt the key. 

To further speed up the process, Akira often uses a “spotting” technique, encrypting only a percentage of each file. This renders the file unusable while allowing the ransomware to cripple a massive file server in minutes rather than hours.

Code analysis suggests that Akira may be built upon the leaked source code of the now-defunct Conti ransomware. If you have dealt with Conti in the past, the remediation steps are similar (we’ll get to those in a moment). 

Intermittent encryption can make data recovery more complex, as files are not damaged in the same way. However, it may also open up opportunities for the recovery of specific files. 

Primary Akira Attack Vectors

Akira is notorious for exploiting network infrastructure.The group aggressively targets Cisco AnyConnect SSL VPNs and SonicWall gateways. They frequently exploit specific vulnerabilities, such as CVE-2023-20269, which allows attackers to brute-force credentials on systems that do not have Multi-Factor Authentication (MFA) enabled.

Like many other groups, they scan for open RDP ports and use compromised credentials to gain entry. Penetration testing (PEN testing) can help to close potential vulnerabilities. 

The Linux / ESXi Variant

A major differentiator for Akira is its capability to target Linux environments, specifically VMware ESXi servers. By targeting the hypervisor (the layer that manages virtual machines), they can encrypt all the virtual servers running on a host simultaneously.

Note: The Linux variant of Akira functions differently than the Windows version and requires different recovery strategies.

Double Extortion

Akira operates a “leak site” on the dark web. Before encrypting your data, they exfiltrate sensitive documents. If you refuse to pay the ransom for the decryption key, they threaten to publish this stolen data publicly.

Steps to Take After an Akira Ransomware Infection

If you identify the .akira extension or receive a ransom note, your immediate actions matter. We recommend taking the following steps: 

Step 1: Disconnect But Do Not Power Down

Immediately disconnect infected machines from the network to prevent the ransomware from spreading to other subnets or backup servers.

Warning: Do not reboot or power down the infected machines. In some rare ransomware scenarios, encryption keys are stored in volatile memory (RAM); shutting down the computer can wipe this key, making recovery impossible even if a decryptor is found/developed. 

Step 2: Secure Your Backups

Verify the status of your backups immediately. If your backups are connected to the network (e.g., a NAS drive or a mapped cloud drive), the ransomware may have encrypted them as well. Isolate your backup media immediately.

Step 3: Check for Public Decryptors

In June 2023, security researchers at Avast released a decryption tool for then-current versions of Akira ransomware. The tool can be found at the No More Ransom project.

The Akira gang acknowledged this flaw and patched their code shortly after. If you were infected by a newer version of Akira (post-August 2023) or the Linux variant, the tool may not work. Datarecovery.com can help you analyze your infection and determine whether free decryptors are an option; we can also help you identify vulnerabilities that led to the attack.

Step 4: Preserve the Logs

Do not wipe the machines to reinstall Windows immediately. Forensic logs (firewall logs, event viewer logs) can help to determine how the attackers got in. If you wipe the evidence, you cannot patch the hole — and you might face another attack.

The post Akira Ransomware: Ransomware Threat Assessment appeared first on Datarecovery.com.

The U.S. Department of the Treasury has taken decisive action against the financial infrastructure fueling the global ransomware epidemic. 

Per AP News, the Office of Foreign Assets Control (OFAC) has sanctioned Russian national Sergey Ivanov and the payment processor Cryptex. Ivanov is accused of laundering hundreds of millions of dollars in virtual currency for cybercriminals, including ransomware gangs and darknet marketplace vendors.

For business leaders and IT administrators, this development reinforces a critical reality: The ransomware ecosystem is a state-entangled economy. 

Ransomware Is A Global Threat, But Some States Are More Responsible

While ransomware is a global threat, the most sophisticated and damaging gangs are frequently based in Russia and North Korea. As we have discussed in previous Datarecovery.com articles regarding ransomware gangs in sanctioned countries, these operators do not work in a vacuum. In many cases, they operate with the tacit approval — or direct encouragement — of their governments.

• Russia: Often serves as a safe harbor for financially motivated gangs, provided they do not target Russian interests. The laundering services provided by actors like Ivanov allow these gangs to convert cryptocurrency into fiat currency.
• North Korea: Utilizes cybercrime as a significant revenue stream for the state. Groups like the Lazarus Group target financial institutions and healthcare providers to fund the regime’s weapons programs.

The designation of Ivanov and Cryptex serves as a stark warning to victims: Don’t pay the ransom. Paying a ransom is often illegal, and it’s not necessarily effective — about 25% of victims who pay do not restore access to their files.

Paying for Ransomware Is a Risky Proposition

When a company pays a ransom, they are not just buying a decryptor; they’re effectively transferring funds across borders. If those funds end up in the hands of a sanctioned individual (like Ivanov) or a sanctioned jurisdiction (like North Korea or Iran), the payer may be held strictly liable by OFAC.

OFAC sanctions violations can result in severe civil and criminal penalties. “Strict liability” means you can be fined even if you did not know you were paying a sanctioned entity.

But just as importantly: Paying a ransom provides an incentive for further attacks.

The Treasury’s actions against money launderers like Ivanov are a positive step, but they do not remove the immediate threat to your organization. If you are targeted, the options aren’t “pay or lose everything.”

A drawer full of donor hard drives in Datarecovery.com’s parts inventory.

A new USB device is attracting attention for offering a “military-grade” solution to a common problem: How to permanently erase sensitive data from a hard drive. 

The device appears to be the sole offering of the brand DESTRUCT, which claims it utilizes advanced algorithms and multi-pass techniques to thoroughly overwrite disk contents. 

But for most users, this dedicated hardware may be unnecessary. We haven’t worked with a DESTRUCT USB gadget, but we’ve seen similar tools — and for the most part, they’re overkill. Here’s why. 

USB Data Sanitization Gadgets: Not a Scam, But Nothing Special

The Destruct gadget plugs into a computer’s USB port and, as Yahoo! Tech reports, operates as a bootable environment to execute data sanitization software automatically. 

Operating outside the computer’s primary operating system is key because it allows the device to overwrite the entire drive, including the OS, boot sectors, and hidden partitions. The goal is to ensure all data is destroyed by running comprehensive multi-pass programs.

The issue? You can download free software that performs the same function. If you’ve got a spare USB drive, for example, you might grab Darius Boot and Nuke (DBAN), a totally free utility that provides multiple options for data sanitization.

What Is “Military-Grade” Data Sanitization?

The term “military-grade” refers to highly specific, multi-pass overwriting standards, most famously the U.S. Department of Defense’s DoD 5220.22-M standard. We’re assuming that the Destruct gadget uses those methods, since buyers on Amazon have noted that the device can take multiple days to sanitize a single HDD. 

These multi-pass methods were developed for older, low-density magnetic media where residual magnetic traces might theoretically be detected after a single overwrite. 

“Theoretically” is an important bit of language: We’ve seen residual magnetic traces of data on extremely old media (such as floppy disks), but they weren’t nearly sufficient for data recovery purposes.

Given the high density of modern hard drives, magnetic artifacts are not a serious concern for data recovery (or data sanitization). 

To Sanitize Data, a Single-Pass Overwrite is Sufficient

Today, for modern, high-density hard disk drives (HDDs), a single-pass overwrite with zeros or a random pattern is generally considered sufficient. The original data is made unrecoverable by any known software or laboratory technique. 

Military-grade methods are valid but extremely time-consuming. Learn more about secure data wiping for HDDs in our article, How to Securely Wipe a Hard Drive Before Selling or Recycling It.

For SSDs, A Basic Format Sanitizes the Drive

If you are dealing with a Solid State Drive (SSD), the process is different, and a utility like DBAN isn’t necessary — fully overwriting the memory cells of an SSD will put unnecessary wear on the device. Most data sanitization programs will refuse to execute multiple overwrites on an SSD for that reason.

For a modern SSD, a full format is fine. The drive’s internal firmware uses TRIM to ensure deleted blocks are quickly and completely emptied. The most reliable method is to use the drive’s built-in ATA Secure Erase command, which instantly resets all storage cells. Most SSD manufacturers provide a free utility (e.g., Samsung Magician, Crucial Storage Executive) to execute this command easily.

Understanding the NIST SP 800-88 Guidelines

For commercial, government, or regulated environments, security protocols must be precise and verifiable. The National Institute of Standards and Technology (NIST) created Special Publication 800-88: Guidelines for Media Sanitization, which defines three distinct security levels for data destruction:

1. Clear: A software overwrite (like DBAN). It protects against simple, non-invasive data recovery techniques. This is effective for HDDs but is considered a minimum level of security.
2. Purge: Protects against state-of-the-art laboratory attacks. For HDDs, this involves degaussing (destroying the magnetic field) or a certified multiple-pass overwrite. For SSDs, it usually involves cryptographically erasing the encryption key.
3. Destroy: The most secure method, rendering the media permanently unusable. It involves physical destruction methods like incineration, pulverizing, or shredding.

These defined standards ensure that organizations select the correct sanitization method to meet their specific risk profile, regulatory obligations (like HIPAA), and the type of storage media they are using.

When Professional Data Sanitization Is Required

For individuals, a quick USB gadget or a free utility is sufficient. However, when decommissioning assets for a business, a healthcare provider, or a government organization, security and legal compliance are the top priority.

Protecting your organization from a data breach requires an auditable, verified, and legally defensible process. This is where professional, at-scale data sanitization services become necessary. 

At Datarecovery.com, we utilize specialized hardware and processes, such as magnetic degaussing and certified software solutions that meet or exceed the NIST standard. Crucially, we maintain a complete chain of custody — documentation that is essential for passing an audit or meeting regulatory requirements. 

If your organization has decommissioned data storage media and requires a verified, certified, and compliant destruction process, we offer secure solutions.

The Washington Post has

The attack has been linked to the Clop ransomware group. Bad actors reportedly exploited a zero-day vulnerability in Oracle’s E-Business Suite, a widely used enterprise software for managing HR and financial operations. 

According to the Post’s data breach notification, the company was first alerted to the problem on September 29, 2025, when the bad actor contacted them directly. 

Key facts about the breach:

• Attack Window: The attackers had unauthorized access to the Oracle environment for over six weeks, from July 10 to August 22, 2025.
• Number Affected: The breach exposed the data of 9,720 individuals.
• Data Stolen: The compromised information was extensive and includes full names, Social Security numbers, bank account and routing numbers, and tax ID numbers.
• Vulnerability: The attack vector was a previously unknown flaw, now identified as CVE-2025-61882, in the Oracle software.
• Discovery Lag: The breach was active for more than a month before the attackers themselves notified the company, after which an internal investigation confirmed the extent of the theft on October 27, 2025.

Below, we’ll discuss how the Clop ransomware gang typically operates and provide some general tips for reducing ransomware exposure.

Clop Ransomware Gang: Exploit Bugs, Exfiltrate Data, Extort Victims 

Clop has a well-established history of targeting third-party software. This is the same group responsible for the massive MOVEit Transfer hack, which compromised thousands of organizations globally by exploiting a single vulnerability in a popular file-transfer tool.

Clop’s modus operandi is to identify a zero-day flaw in a widely used piece of enterprise software, exploit it to steal data from as many users as possible, and then issue extortion demands. We have been tracking Clop’s activities for years, and the Washington Post breach confirms their continued focus on high-impact supply-chain attacks.

An Action Plan for Ransomware Exposure

If you suspect your organization has been compromised by ransomware, the steps you take in the first few hours are critical.

1. Isolate Affected Systems: Immediately disconnect compromised computers, servers, and devices from the network to prevent the ransomware from spreading.
2. Do Not Pay the Ransom: Paying the demand funds criminal activity and offers no guarantee you will receive a working decryption key or that your stolen data won’t be leaked. Additionally, paying for ransomware is often illegal.
3. Assess the Scope: Try to identify the point of entry and which systems are affected, but avoid deep forensic analysis at this stage.
4. Consult Experts Before Restoring: Before you attempt to restore from any backup, speak with a ransomware recovery specialist. It’s important to identify the vulnerability that led to the breach to avoid reintroducing the infection.

Modern ransomware strains often include a dormancy period: The malware will infiltrate a network and remain hidden for weeks or months before activating. 

Those strains are specifically designed to overcome backup strategies. When the attack is finally triggered, the organization restores its data from backups, which reinserts the malware into their key systems.

The post Washington Post Data Breach: Clop Ransomware Gang Remains Active appeared first on Datarecovery.com.

A February 2025 analysis found that 96% of ransomware attacks now include data exfiltration, so multi-factor ransomware attacks are now the standard. 

That’s important for one big reason: It means even perfect backups won’t solve the problem of your data being stolen. We’ll explain the layers of both attack types, what to do following the attack, and how to navigate the disaster recovery process.

How Different Ransomware Models Work

To understand double and triple extortion, it helps to compare the models: 

Standard (Single) Ransomware

Malware encrypts your files, making them unusable. You’re then presented with a ransom note demanding payment (usually in cryptocurrency) in exchange for a decryption key.

In this model, the solution was simple: if you had good, offline backups, you could wipe the infected systems, restore your data, and ignore the ransom. Unfortunately, the sheer profitability of ransomware has led bad actors to more sophisticated methods.

Double-Extortion Ransomware

Double-extortion ransomware has two distinct stages. Before any files are encrypted, the attackers identify sensitive data (financial records, customer lists, intellectual property), and copy it to their own servers.

After the data is stolen, the attackers deploy the ransomware, which encrypts your files and delivers the ransom note.

The two degrees of extortion:

1. Pay for the decryption key to unlock your files.
2. Pay that same fee (or an additional fee) to guarantee they will delete the stolen data and not leak it publicly or sell it on the dark web.

Even if you restore from backups, you still face a public data breach. 

Triple-Extortion Ransomware

Triple-extortion adds a third layer of operational pressure. Common “third-layer” tactics include:

• Distributed Denial-of-Service (DDoS) Attacks: The attackers use a botnet to flood your website, servers, or network with junk traffic, knocking you completely offline. Even if you’re trying to restore, your public-facing operations are paralyzed.
• Direct Harassment: Attackers contact your customers, suppliers, partners, or even regulators directly. They inform them of the breach, often exaggerating the severity or leaking small samples of their data to destroy trust in your brand.
• Targeted Internal Pressure: Attackers may email or call high-level executives, employees, or shareholders directly to pressure them to pay.

The goal is to make the situation so chaotic and damaging to your reputation that paying the ransom seems like the fastest solution. Unfortunately, about 25% of victims who pay ransoms are unable to restore their data — and in many cases, paying for ransomware is illegal.

Ransomware Action Plan: First 24 Hours

If you discover a ransom note or suspect an attack is in progress, what you do in the first hour is critical.

1. Isolate Everything: Disconnect the infected systems from the network immediately. Unplug ethernet cables and disable Wi-Fi on all suspicious devices. This includes servers, workstations, and network-attached storage. Your top priority is containment to stop the malware from spreading.
2. Secure Your Backups: Verify the status of your backups. If they are online and connected to the network, disconnect them now to protect them from being encrypted. Offline (air-gapped) and immutable (read-only) backups are your best defense here.
3. Don’t Wipe or Pay (Yet): Resist the urge to immediately wipe drives. Wiping the drives can destroy the encrypted data that might be recoverable. Do not pay the ransom.
4. Document the Attack: Start a log of everything you find. Take photos of the ransom note (do not click any links in it). Note the time you discovered the attack, the systems affected, and the steps you’re taking. 
5. Report It: Contact our ransomware experts. It’s also advisable to contact law enforcement (in the U.S., this is your local FBI field office or the Internet Crime Complaint Center (IC3)).

This vulnerability, tracked as CVE-2024-1086, is exceptionally dangerous because it allows an attacker with only a minor foothold to escalate their privileges and take over your entire system.

In this article, we’ll take a look at CISA’s warning. If you’ve lost data due to ransomware, we’re here to help. Call 1-800-237-4200 for a free consultation or submit a ticket online.

Understanding the CVE-2024-1086 Flaw

At its core, CVE-2024-1086 is a “use-after-free” vulnerability. It’s a memory management bug within a specific part of the Linux kernel called netfilter: nf_tables, which is a component that handles network packet filtering.

The bug has existed in the Linux kernel for over a decade. It allows a local attacker who has already gained basic user access to trick the system into giving them root privileges.

Note: For those unfamiliar, “root” is the all-powerful administrator account on a Linux system. Gaining root is the ultimate goal for any attacker. 

Why This Flaw Is a Gift to Ransomware Gangs

In our labs, we see the aftermath of attacks like this every day. For a ransomware attack to be truly devastating, the attackers can’t just encrypt the files of a single, low-level user. They must gain administrative control. 

This is why privilege escalation flaws like CVE-2024-1086 are so valuable to bad actors. With root access, an attacker can:

• Disable Security Software: They can instantly stop or uninstall all antivirus, endpoint detection (EDR), and monitoring tools that would otherwise detect them.
• Encrypt Everything: They gain the ability to read, modify, and encrypt all files on the system, including critical databases, server configurations, and virtual machines.
• Destroy Backups: Root access lets them find and delete all connected backups, shadow copies, or snapshots, so you have no easy way to recover.
• Move to Other Systems: Once they are root on one machine, they can use that access to pivot and attack other servers on your network.

CISA’s Warning: Take Action to Patch the Exploit

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has been tracking this vulnerability for months. It was added to their Known Exploited Vulnerabilities (KEV) catalog back in May 2024, with a directive for federal agencies to patch.

However, the situation has now escalated. CISA is explicitly warning that this flaw is being “exploited in ransomware attacks.” This confirmation moves it from a “you should patch this” problem to a “you are being actively hunted” problem.

Given that this vulnerability is being used for ransomware:

1. Patch Immediately: Patches for this flaw have been available for months from all major Linux distributions, including Red Hat, Ubuntu, Debian, and Fedora. You must apply these security updates without delay.
2. Hunt for Existing Security Compromise: Patching a vulnerability today does not fix a compromise that happened yesterday. You must review your logs and system activity for any signs of a breach, such as unusual user access or privilege escalation events.
3. Use Mitigations (If You Can’t Patch): If you are running a legacy system that cannot be patched, CISA advises temporary mitigations. These include blocklisting the nf_tables module (if you don’t use it) or restricting user namespaces to limit the attack surface.

For bad actors, ransomware is a lucrative business, and modern malware variants have an exceptionally high degree of sophistication. Even so, ransomware recovery is possible in many scenarios — though the prognosis varies depending on the variant. 

So, how can you get your data back after a ransomware attack? Paying the ransom is one option, but it’s not a great one: It doesn’t result in a return of funds in a surprisingly high percentage of cases, and it may be illegal depending on the location of the attacker. Each ransomware payment also incentivizes ransomware, so the best tactic is to explore options that don’t reward extortion. 

In this article, we’ll explore several common scenarios where ransomware recovery is possible. If you’ve been victimized by ransomware, we’re here to help: Datarecovery.com provides flexible service options (including 24/7 service), and our no data, no charge guarantee gives you peace of mind as your case progresses.

Scenarios for Successful Ransomware Recovery

We should note that this is not an exhaustive list of potential ransomware recovery scenarios. As with traditional data recovery, ransomware cases must be evaluated by an experienced specialist to determine the prognosis. 

With that in mind, success stories for ransomware cases often include: 

1. Recovery from Secure Backups

If you have offline, air-gapped, or immutable backups, recovery is a straightforward (though still intensive) process of restoring your systems

• Offline Backups: These are physically disconnected from the network, such as an external hard drive you unplug after backing up.
• Air-Gapped Backups: Similar to offline, but implies a system or network that is never connected to the public internet or your primary business network.
• Immutable Backups: These are backups (often cloud-based) that are locked in a “read-only” state for a set period. Even with administrator credentials, the ransomware cannot delete or alter them.

The bad news: Some ransomware variants have long dormancy periods, which allow bad actors to neutralize all of the victim’s backups (even including air-gapped tapes). 

If you’re recovering from an attack, we strongly recommend working with ransomware experts during disaster recovery planning. Specialists can help you determine whether backups are viable and fully sanitize systems prior to restoration.

2. Public Decryptor Tools

Cybersecurity researchers and law enforcement are in a constant battle with ransomware groups. When they find a flaw in the malware’s code or seize an attacker’s servers, they often recover the master decryption keys — and in some cases, they’re able to release functional decryptors for specific ransomware families.

The No More Ransom project, a joint initiative by law enforcement and IT security companies, is the most trusted source for these tools. If you can identify the ransomware strain (often from the ransom note or file extension), you can check if a free tool is available.

Note that decryptor tools have limited support, and if used improperly, they could potentially result in data loss (as is the case with any type of data recovery software). If you’re at all uncomfortable with the process, set up a ticket to speak with a ransomware specialist.

3. Intact Volume Shadow Copies (VSS)

Windows creates automatic point-in-time snapshots of your files called Volume Shadow Copies (VSS). That’s the feature that powers “System Restore” and the “Previous Versions” tab in a file’s properties.

Most modern ransomware attempts to delete these shadow copies, but the script can fail (we often see this happen if the attack is run with insufficient user privileges or is interrupted). If the VSS files are intact, we can often roll back the files to their pre-encryption state.

4. Recovery via Data Carving

Most ransomware doesn’t edit your original file. Instead, it follows a three-step process:

1. It reads your original, unencrypted file (e.g., document.pdf).
2. It creates a new, encrypted copy (e.g., document.pdf.locked).
3. It deletes the original document.pdf.

That “deleted” file isn’t immediately erased. The space it occupies on the hard drive is simply marked as “available” by the operating system, waiting to be overwritten by new data. 

Using advanced forensic tools, our engineers can scan the drive’s raw, unallocated space to find and carve out these original, unencrypted files. 

Note: The success of data carving depends heavily on how much the computer was used after the attack. The more new data is written, the higher the chance the original files will be overwritten and permanently lost. For that reason, we recommend disconnecting the power source as soon as you find signs of ransomware infection.

We should also note here that some ransomware variants do use in-place encryption. Data carving is not an option for those variants. 

5. Flawed or “Fake” Encryption

Not all ransomware creators are criminal masterminds. We see poorly coded variants frequently, and some strains have major flaws: weak encryption, static keys (meaning the same decryption key for every victim), and scareware (malware that acts like ransomware without actually encrypting anything). 

Even if there’s no public decryptor tool for a certain ransomware variant, there’s a chance that the malware is simply — well, badly made. For example: 

• TeslaCrypt: After researchers exploited an early encryption flaw, the developers of TeslaCrypt eventually shut down their operation in 2016 and publicly released the master decryption key.
• CrySiS: The master decryption keys for the CrySiS ransomware family were leaked on a BleepingComputer public forum in 2016, allowing security firms to create free decryptors.
• HiddenTear: This open-source “proof-of-concept” ransomware was published on GitHub, allowing researchers to easily analyze its code and defeat the many flawed variants created by amateur criminals.
• Original Petya (2016): The first version of Petya, which attacked the Master File Table, contained a critical cryptographic error (see “April 2016” entry) that allowed a researcher to develop a tool that could generate the decryption key almost instantly.

6. Partial File Encryption

To encrypt a 50 GB video file or virtual machine database, it would take a long time. To speed up the attack, some ransomware strains only encrypt the first few megabytes (MB) of large files. That’s enough to corrupt the file “header” and make it unreadable by any program, but the data can be restored relatively easily past that point. 

For certain file types, especially large videos, databases, or virtual disks, the vast majority of the data remains intact and unencrypted. Specialist techniques can be used to rebuild the file headers or extract the undamaged data, allowing for a partial or even full recovery of the file.
