How to Safely Remove DevMan2 Ransomware and Protect Your Files?
Introduction
DevMan2—also branded as DEVMAN 2.0—is a ransomware-as-a-service (RaaS) variant rooted in the DragonForce/Conti ransomware lineage. While technically not a wholly new strain, it’s a significant campaign iteration with notable impacts across industries worldwide.

Extension, Ransom Note File, & Self-Encryption Flaw
- Encrypted files receive a .DEVMAN extension—e.g., document.docx.DEVMAN.
- A rare builder flaw causes the ransomware to encrypt its own ransom note, renaming it to a deterministic filename like README.yAGRTb.txt.
This self-encryption complicates negotiations for victims, as note contents are inaccessible.

Recovering Files with the DevMan2 Decryptor Tool
The DevMan2 Decryptor Tool is a specially engineered utility designed to help victims of DEVMAN 2.0 ransomware recover their encrypted data without paying the ransom. This tool works by identifying the specific encryption methods used by DevMan2 and applying customized decryption protocols in real-time via secure servers.
How the Tool Works?
The Decryptor analyzes the encryption pattern used by DevMan2, including file extensions like .DEVMAN, and connects to our secure backend to retrieve or compute decryption keys when available. It is compatible with most environments targeted by the ransomware, including desktops, Windows servers, and network-attached storage (NAS) systems.
Step-by-Step Recovery Guide
- Purchase the Tool Securely: Reach out to our support team via WhatsApp or email. Upon payment confirmation, you will receive immediate access to the Decryptor tool.
- Launch with Admin Rights: Open the DevMan2 Decryptor as an administrator to ensure it functions properly. A stable internet connection is required for secure server communication.
- Input Your Victim ID: Extract the victim identifier from the ransom note file—typically one that ends in .devman—and enter it into the tool to initiate the decoding logic.
- Start Decryption: Begin the decryption process. The tool will automatically restore your files to their original state without causing damage or data loss.

Technical Profile & Tactics
- Offline operation: conducts encryption and uses SMB to spread laterally—without.
- Tri-mode encryption: supports full, header-only, and custom methods for balanced speed vs. thoroughness.
- File-lock bypass: employs Windows Restart Manager and registry-mutex techniques to circumvent locked files.
- OS irregularity: wallpaper changes function on Windows 10 but fail on Windows 11.
- Mutex usage: fixed mutex (e.g., hsfjuukjzloqu28oajh727190) stops duplicate instances.

Visual profile of the victims of devman2:
Campaign Timeline & RaaS Background
- First seen: April 2025 (as Devman/Devman 1.0).
- “DevMan2 / DEVMAN 2.0” launch: Early July 2025, with a new leak site and branding under Tor (wugurgyscp…onion).
- Magnitude: Cyble data shows DevMan claimed 13 victims in May 2025 alone, ranking just outside the top 5 ransomware groups.
Key Indicators of Compromise (IOCs)
- File extensions: .DEVMAN
- Ransom note filename: encrypted note like README.yAGRTb.txt.
- Mutex strings: e.g., hsfjuukjzloqu28oajh727190.
- Registry RPM keys: under HKEY_CURRENT_USER\Software\Microsoft\RestartManager\Session0000.
- SMB activity: probing ADMIN$ shares.
- Offline behavior: no external C2, local encryption only.

Defensive & Recovery Recommendations
- Monitor for .DEVMAN extensions and mutated ransom notes.
- Audit SMB access logs, specially ADMIN$ tasks.
- Maintain off-network backups (3-2-1 model).
- Enable EDR solutions to catch registry and mutex anomalies.
- Patch regularly, especially Windows 10/11 servers.
- User training on phishing and RDP/vpn credential risks.
Conclusion
DevMan2 or DEVMAN 2.0 represents the latest campaign wave of the existing DevMan RaaS operator. While not a new ransomware family, its technical quirks—especially the self-encryption of the ransom note and offline SMB-based propagation—make it uniquely detectable and leakage-rich.
