What Makes Dzen Ransomware Unique?

While many ransomware strains share common traits, Dzen introduces several distinctive features that elevate it as a more sophisticated threat. First identified in April 2024 by CYFIRMA’s research team, Dzen ransomware not only encrypts files but also disables critical system defenses like firewalls, leaving systems exposed to further malicious activity.

Advanced Evasion Techniques

Dzen ransomware actively disables Volume Shadow Copies, making it nearly impossible for victims to recover files without paying the ransom. This tactic is particularly troubling because it neutralizes one of the more accessible methods of file restoration that many users rely on during ransomware attacks.

Moreover, Dzen employs advanced location data collection techniques and selective persistence mechanisms. Unlike many other ransomware strains, it avoids specific regions in its operations, demonstrating a tailored approach to maximize the success of its attacks.

Dzen’s Targeted Technologies and Victimology

Dzen ransomware primarily attacks systems running Microsoft Windows, a widely used operating system across industries. From healthcare to finance, it indiscriminately strikes at organizations with vulnerable systems. However, what’s particularly concerning about Dzen is its ability to disable system firewalls via a registry key modification (HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\PublicProfile\EnableFirewall), making it more dangerous than traditional ransomware, which usually relies solely on encryption.

How Dzen Ransomware Differs from Other Phobos Variants

Dzen belongs to the Phobos ransomware family, a group that has terrorized industries since 2019. However, Dzen differentiates itself with more aggressive evasion strategies and tighter control over compromised systems. While most Phobos variants lock up files and demand a ransom, Dzen takes this further by removing system logs and using virtualization evasion techniques to avoid detection in sandbox environments.

Additionally, Dzen disables tools that could be used to analyze and reverse-engineer its encryption algorithms, making it difficult for cybersecurity professionals to develop decryptors.

Key Tactics and Techniques (TTPs) Used by Dzen Ransomware

Dzen ransomware employs several key tactics from the MITRE ATT&CK Framework:

1. Execution: Using scheduled tasks and native APIs to execute commands without detection.
2. Persistence: Autostart execution via registry run keys ensures Dzen can reload upon system reboot.
3. Privilege Escalation: Through access token manipulation and boot execution, the ransomware gains higher system privileges.
4. Defense Evasion: Dzen obfuscates files, deletes logs, and manipulates file permissions, making it difficult for security tools to detect or block it.

These techniques make Dzen one of the more elusive ransomware variants within the Phobos family.

Ransom Negotiation and Recovery: What Victims Should Know

One of the more alarming aspects of Dzen ransomware is its strict ransom negotiation process. Victims receive two ransom notes—info.txt and info.hta—that emphasize immediate payment. If the ransom is not paid within 48 hours, the attackers threaten to release stolen data or share it with interested third parties.

No Free Decryptor Available

At present, there is no publicly available decryptor for Dzen ransomware. Victims are warned against attempting third-party decryptions, as they may cause permanent data loss or increase the ransom demands. The Phobos Decryptor, Is very effective for Dzen and been confirmed to work on Dzen.

How the Phobos Decryptor Could Help with Dzen Ransomware

The Phobos Decryptor is a specialized tool developed to decrypt ransomware strains within the Phobos family, and it may offer a glimmer of hope for Dzen victims. Despite Dzen’s sophisticated encryption mechanisms, the Phobos Decryptor has demonstrated potential in cases where known vulnerabilities in encryption algorithms exist. Here’s how the Phobos Decryptor assists in recovering files encrypted by Dzen ransomware:

Server-Side Decryption

The Phobos Decryptor connects to secure servers capable of calculating the necessary decryption keys for files encrypted by Dzen. This eliminates the need to engage with the attackers or pay the ransom, providing a more legitimate pathway to file recovery. While not guaranteed to work with every Dzen infection, the tool’s ability to leverage server-side decryption gives victims a viable alternative to ransom payments.

User-Friendly Interface

One of the main advantages of the Phobos Decryptor is its user-friendly interface. Designed for ease of use, it requires no deep technical knowledge, making it accessible even to those with limited IT expertise. The tool walks users through each step, simplifying the complex decryption process.

Data Integrity

A significant benefit of the Phobos Decryptor is its ability to decrypt files without further corrupting data. In many ransomware cases, attempts to decrypt files using incorrect methods can cause irreversible damage. The Phobos Decryptor, however, is designed to maintain the integrity of the data during recovery, making it a trusted tool for businesses and individuals alike.

Steps to Use the Phobos Decryptor for Dzen Ransomware

For those affected by Dzen, here are the general steps to use the Phobos Decryptor:

1. Obtain the Phobos Decryptor: Contact Us to buy the Phobas Decryptor.
2. Install the Decryptor: Set up the tool on the infected system, ensuring the computer remains connected to the internet.
3. Connect to the Server: The Phobos Decryptor requires a stable internet connection to communicate with its decryption servers.
4. Input the Victim ID: Enter the unique victim ID, which is typically found in the ransom note or appended to the encrypted filenames.
5. Decrypt the Files: Hit the “Decrypt” button and allow the tool to work through the affected files.

Remote Support

In case of technical issues during the decryption process, the Phobos Decryptor’s team provides remote support to assist users and ensure a smooth recovery.

Alternative File Recovery Methods

While the Phobos Decryptor remains one of the more effective tools for Phobos ransomware, victims of Dzen may still explore other options if the decryption tool proves inaccessible or ineffective:

1. Free Data Recovery Tools: Applications like PhotoRec or TestDisk may help recover unencrypted remnants or previously deleted files. However, these tools cannot decrypt ransomware-encrypted files directly.
2. System Restore: If Volume Shadow Copies are intact, System Restore can revert the system to a pre-infection state, though this method will not decrypt any locked files.
3. Professional Data Recovery Services: In severe cases, data recovery experts can attempt to recover files using advanced techniques. However, these services are often costly, and success is not guaranteed.

Strategic Recommendations for Organizations

To minimize the risk of a Dzen ransomware infection, businesses and individuals should adopt comprehensive cybersecurity measures:

• Implement Zero-Trust Architecture: This approach assumes no user or system is automatically trusted and continuously verifies every request, reducing the risk of lateral movement by attackers.
• Multifactor Authentication (MFA): Add an extra layer of security to user accounts, making it more difficult for attackers to gain unauthorized access.
• Network Segmentation: Separate critical systems from less important ones, ensuring that an infection in one area does not compromise the entire network.

Tactical Recommendations: Staying Ahead of Dzen Ransomware

For tactical protection against Dzen ransomware, companies should consider the following:

• Regular Software Updates: Keep all systems patched and updated to close known vulnerabilities that ransomware could exploit.
• Endpoint Detection and Response (EDR): Use advanced tools to monitor, detect, and respond to suspicious activities within your network.
• Offline Backups: Store backups in a secure, offline environment. In the event of an attack, these backups are crucial for restoring critical data without paying the ransom.

The Future of Dzen Ransomware: A Growing Threat

As Dzen ransomware continues to evolve, experts anticipate that its encryption methods will become more complex, and its attack techniques will adapt to target more regions and industries. Already, Dzen shows signs of expanding beyond its initial geographic focus, posing a global threat to businesses and individuals alike.

Cybersecurity experts warn that variants like Dzen will increasingly leverage anonymization tactics and decentralized communication channels to evade detection, further complicating recovery efforts for victims.
