How It Works?
AI + Blockchain Analysis
Encrypted files are processed in a secure, isolated environment where AI identifies encryption patterns. A private blockchain ledger verifies every decrypted output for integrity and authenticity.
Login ID-Based Mapping
Gentlemen ransom notes contain unique victim IDs. Our decryptor uses these to align with the correct encryption batch for accurate recovery.
Universal Key Option
For cases where ransom notes are missing, we provide a Universal Decryptor that can handle updated variants of Gentlemen ransomware.
Secure Execution
Our tool performs read-only scans first, preventing accidental data corruption before full decryption begins.

Requirements
To use our decryptor, you will need:
- A copy of the ransom note (commonly named gentlemen_readme.txt or equivalent).
- Access to encrypted files.
- Stable internet connection (for cloud processing and integrity checks).
- Local or domain admin privileges.
Immediate Steps to Take After Gentlemen Ransomware Attack
- Disconnect Immediately
Isolate compromised systems to stop ransomware spread across endpoints, servers, and backups. - Preserve Everything
Do not delete ransom notes or encrypted files. Save logs, file hashes, and traffic captures. - Shut Down Affected Systems
Avoid reboots, as Gentlemen has been observed deploying persistence scripts that trigger further encryption on restart. - Contact a Recovery Expert
DIY decryption attempts often result in corruption. Work with professionals for the highest recovery success rate.
How to Decrypt Gentlemen Ransomware and Recover Your Data?
Gentlemen ransomware has rapidly evolved since its emergence in mid-2023, targeting organizations in finance, manufacturing, healthcare, and government sectors.
Our specialized decryptor leverages cryptographic flaws and timestamp analysis to restore files safely, without ransom payment.
Gentlemen Decryption and Recovery Options
Free Methods
1. Open-Source & Research Decryptors
Early builds of Gentlemen ransomware used weaker key derivation methods. Some independent researchers have released partial decryptors for these legacy variants.
2. Backup Restore
If immutable or off-site backups exist, these remain the cleanest recovery path. Before restoring, always verify backups using checksums — some backups may have been partially tampered with.
3. VM Snapshots
In VMware or Hyper-V environments, reverting to pre-attack snapshots can restore operations within minutes. However, confirm integrity first — Gentlemen has been known to delete snapshots if hypervisor access was achieved.
4. GPU-Based Brute Force Attempts
Like Akira, Gentlemen’s encryption timestamps can sometimes be brute-forced using CUDA-compatible GPUs. However, modern samples require quadrillions of combinations, making brute-force recovery infeasible for most organizations.
Paid Methods
Paying the Ransom
While paying may yield a decryptor from the attackers, risks include:
- No guarantee of working keys.
- Backdoored tools with tracking scripts.
- Violation of local laws supporting terrorism or cybercrime.
Third-Party Negotiators
Negotiators act as intermediaries, sometimes lowering ransom costs or validating attacker tools. Downsides:
- High fees (flat retainers or % of ransom).
- Time delays that risk permanent data loss.
Our Specialized Gentlemen Ransomware Decryptor
Unlike public tools, our enterprise-grade decryptor has been optimized for Gentlemen variants active through 2025.
How It Works?
- Reverse Engineering – Our research team analyzed leaked samples and identified encryption flaws.
- Cloud Decryption – Encrypted files are securely uploaded for analysis; decrypted versions are returned with full integrity logs.
- Fraud Prevention – Unlike shady online tools, our solution is backed by audited recovery cases and verified by enterprise clients.
Step-by-Step Gentlemen Recovery Guide
- Assess the Infection
Confirm file extensions (.gentlemen, .locked, or .gnlt) and check ransom note presence. - Secure the Environment
Disconnect systems, disable admin credentials possibly leaked, and ensure persistence scripts are inactive. - Submit Samples
Provide encrypted files + ransom notes for variant confirmation. - Run Decryptor
Launch with admin rights → enter victim ID → start decryption.

Offline vs Online Recovery
- Offline Recovery: Ideal for air-gapped systems and classified environments. Uses external drives + secure boot machines.
- Online Recovery: Faster, real-time expert assistance. Uses encrypted transfer + blockchain verification.
Our solution supports both modes, offering flexibility across enterprises and government infrastructure.
What is The Gentlemen Ransomware?
Gentlemen is a Ransomware-as-a-Service (RaaS) group first observed in late 2023. By 2024, it expanded aggressively into finance, healthcare, and industrial sectors, often using double extortion tactics — stealing sensitive data before encryption.
Unlike opportunistic ransomware, Gentlemen is targeted, aiming for high-value corporate environments.
How Gentlemen Works: The Inside Look
Initial Access Vectors
- VPN Brute Forcing – Cisco and Fortinet VPNs without MFA are frequent entry points.
- Exploiting Known CVEs – Notably CVE-2022-40684 (Fortinet) and CVE-2023-34362 (MOVEit).
- Phishing Campaigns – Employees are tricked into credential leaks or malware execution.
- RDP Exploitation – Internet-exposed RDP endpoints remain a key target.
Tools, TTPs & MITRE Mapping
- Credential Theft – Mimikatz, LaZagne (MITRE T1003).
- Reconnaissance – SoftPerfect Network Scanner, AdFind (MITRE T1018).
- Defense Evasion – BYOVD attacks abusing unsigned drivers, PowerTool for rootkits (MITRE T1562).
- Data Exfiltration – WinSCP, RClone, Ngrok tunnels (MITRE T1048, T1567).
- Encryption – ChaCha20 for speed + RSA for key protection. Shadow copies deleted using vssadmin.
Known Gentlemen Indicators of Compromise (IOCs)
- File Extensions: .gentlemen, .locked, .gnlt, .ojuopo
- Ransom Note: gentlemen_readme.txt.
- Suspicious Tools: Mimikatz, AnyDesk, RClone, FileZilla in unusual directories.
- Outbound Traffic: Mega.nz, Ngrok.io, custom TOR C2 servers.
Mitigations & Best Practices
- Enforce MFA on VPN/RDP logins.
- Patch Regularly — especially firewalls, VPNs, and file transfer software.
- Segment Networks — limit lateral movement.
- Block BYOVD Exploits — allow only signed, verified drivers.
- Invest in MDR/SOC Monitoring for real-time detection.

Example Gentlemen Ransom Note
Victims typically receive gentlemen_readme.txt with messages such as:
“Your files are encrypted. We also downloaded your sensitive data. To recover, contact us via TOR.
Failure to comply will result in data sale or public leak.”
Conclusion: Restore Your Data, Reclaim Your Network
The Gentlemen ransomware is a fast-evolving, high-impact RaaS threat. Paying ransom funds criminal enterprises and carries no guarantees. Instead, trust proven decryptors and recovery specialists.
Our Gentlemen Decryptor has helped dozens of enterprises restore encrypted files across Windows, Linux, and ESXi systems — safely, quickly, and without ransom payments.
