The Gentlemen Ransomware: What You Need to Know & How to Recover Fast
The Gentlemen is one of 2026’s busiest ransomware operations, hitting manufacturers, healthcare providers and public bodies, and its encryptor can spread itself to every reachable system on a network. See how it gets in, what the README-GENTLEMEN.txt note demands, and — if your systems are compromised — how our experts help you restore encrypted data and get back to business.
What is The Gentlemen Ransomware?
The Gentlemen is a ransomware operation first seen around mid-2025 that breaks into organisations through exposed VPN gateways and credentials bought from access brokers. Its Windows encryptor is written in Go, separate lockers cover Linux, NAS and VMware ESXi, and before encrypting it disrupts backup tools such as Veeam and Backup Exec. BeforeCrypt has handled multiple engagements involving The Gentlemen and can help you contain the attack, assess your recovery options and restore operations safely.
Double extortion model
Data is exfiltrated before encryption, giving affiliates leverage even if you can restore from backup.Broad sector targeting
Trend Micro documented heavy focus on manufacturing, construction, healthcare and insurance; Microsoft later observed education, transportation, healthcare and financial victims.Security tool evasion
Trend Micro documented BYOVD abuse of the vulnerable signed driver ThrottleBlood.sys in its 2025 campaign analysis; in June 2026 ESET detailed the operators' in-house GentleKiller framework, which targets more than 400 security processes.International affiliate network
ESET found affiliates consistently hitting Southeast Asia, South America and Western Europe; Unit 42 reported one tracker counting 580 victims across 77 countries through 7 July 2026.Why You Shouldn’t Attempt to Fix It Alone
Microsoft’s May 2026 analysis of the Go-based Windows encryptor found it generates a fresh ephemeral Curve25519 key pair for each file, deriving an XChaCha20 file key from an ECDH exchange with the embedded operator public key, so recovery normally depends on backups or the attacker’s key. BeforeCrypt checks for available decryption tools, including free ones, as part of every assessment, and any tool is verified technically and tested on copies first.
Affiliates steal data before encryption, so a clean restore from backup does not remove the leak threat: stolen files are published on the group’s leak site if a victim does not engage. That is a business impact independent of file loss. Notification obligations depend on your sector and geography — see the FAQ below for the regulatory clocks that may apply.
BeforeCrypt can run the full response — triage, containment, eradication, recovery — or support your IT team: establishing what was taken, sanctions screening before any payment, evidence preservation for insurers and regulators, coordinating notification, and contact with the attackers where reducing the demand or buying time is the right route. Handling all of that at once strains internal teams.
An experienced internal security team can handle substantial parts of this response itself. Our detailed emergency response plan walks through the sequence step by step. A free assessment call helps you decide what stays in-house and where specialist support saves time while the deadline runs.
Victims typically find a text file dropped into affected folders, naming The Gentlemen directly and including a unique victim identifier for the negotiation channel. The ransom note directs victims to a Tor-based portal and warns that stolen data will be published if there is no response by a stated deadline.
YOU MUST NOT ATTEMPT TO TOUCH, RESTORE OR OVERWRITE THE DATA.

COMMON ATTACK VECTORS
- Exploit Public-Facing Application (T1190) — Sophos CTU’s September 2026 analysis of 15 intrusions found affiliates compromising Fortinet FortiGate/FortiProxy and other VPN gateways, firewall management interfaces, RDP and remote management tools for initial access.
- Valid Accounts (T1078) — Group-IB and Sophos documented in 2026 that affiliates authenticate with valid credentials, including accounts bought from initial access brokers and infostealer log marketplaces.
- Exploitation of known vulnerabilities (T1190) — leaked internal chats show the group exploiting CVE-2024-55591 (FortiOS/FortiProxy), CVE-2025-32433 (Erlang/OTP SSH) and CVE-2025-33073 (NTLM relay).
- External Remote Services (T1133) — Sophos CTU and Group-IB documented in 2026 that RDP and exposed remote management tools serve as initial access paths, with AnyDesk, PsExec and Datto RMM used afterwards for access and persistence.
RANSOM AMOUNTS
Targeting is broad and access-driven: manufacturing accounted for 103 of the 580 victims a tracker cited by Unit 42 counted through 7 July 2026, with healthcare and government also affected, and affiliates commonly enter through Fortinet VPN appliances or credentials bought from brokers.
One negotiation transcript recovered from the May 2026 leak of the group’s own backend shows an opening demand of USD 250,000 settled at USD 190,000 — a single documented case, not an average demand; leaked chats show operators researching a target’s revenue and corporate structure before setting a demand. Ransoms are usually paid in Bitcoin. Quick-buy methods of purchasing Bitcoin with PayPal or credit cards do not work for this size of ransom payment and it is important to obtain expert advice to ensure that a payment of this size is legally compliant.
Our experienced negotiation team has consistently secured meaningful reductions from the initial demand to the final settlement across The Gentlemen engagements.
AVERAGE LENGTH
Affiliates dismantle the recovery path before encrypting: Sophos recorded more than 200 variations of commands disrupting Veeam, SQL Writer and Backup Exec components, and the encryptor’s –wipe option removes recoverable artefacts from disk.
For most ransomware victims, downtime is the most costly aspect of the incident, with potential for considerable reputational harm.
Our extensive experience with The Gentlemen ransomware gives us a deep understanding of the gang’s tactics, enabling us to resolve attacks swiftly and restore your files.
How to identify The Gentlemen ransomware
The ransom note usually appears as a text file named README-GENTLEMEN.txt, dropped into affected directories and naming The Gentlemen directly. It includes a unique victim identifier and directs contact through Tox messenger and the group’s Tor negotiation portal.
Frequently asked questions
Decryption depends on the ransomware variant. In some cases, publicly available decryption tools exist, but not all attacks have a known solution. You can submit a free ransomware recovery request, and we will check for possible decryption methods.
In most cases involving personal data, which applies to nearly every ransomware incident, reporting is legally required. In the EU, GDPR requires notification to the relevant data protection authority within 72 hours of becoming aware of a personal data breach. The UK ICO requires the same 72-hour window. In the US, HIPAA-covered entities have 60 days to notify affected individuals (and immediately for breaches affecting 500+ people). The clock starts from awareness of the incident, not from a full technical understanding.
In most jurisdictions, paying a ransom is not illegal in itself — but it can become illegal if the payment ends up going to a sanctioned entity or country (OFAC-designated groups in the US, EU sanctions lists, UK Treasury lists). Before any payment, sanctions screening is essential. BeforeCrypt handles this compliance layer as a standard part of every engagement.
Most established ransomware groups do provide working decryption tools when paid — the business model depends on their reputation for delivery. However, decryptors are often slow, incomplete, or corrupt a percentage of files during recovery. This is where working with a specialist matters: BeforeCrypt tracks the delivery reliability of specific groups, negotiates sample-file decryption as proof of capability where the group allows it, and plans realistic recovery timelines based on our own engagement history with each group.
Most modern ransomware groups follow through on publication threats — stolen data appears on the group's leak site, is often mirrored to Telegram and dark web forums, and may be sold to third parties. Recovery becomes limited to whatever you can rebuild from backups.
Backups protect against file loss but not against data theft. Most modern ransomware groups exfiltrate sensitive data BEFORE encryption and threaten to publish it regardless of your recovery capability. This is why leak-site publication and negotiation still matter even for organisations with clean, offline backups — and why "we can just restore from backup" rarely tells the full story.
In most jurisdictions, yes — reporting is a standard part of a ransomware incident and, in some cases, legally required. In the US, that means the FBI (via IC3 or a local field office) and CISA. In the EU, national CERT and cybercrime units. Reporting does not obligate you to any specific recovery path but does open access to threat intelligence and, occasionally, decryption tools recovered by law enforcement.
Yes. We’ve handled 1,700+ incidents across ransomware, BEC and data-leak extortion. We identify the variant, decide decrypt vs. clean verified restore, and guide a controlled return to operations. When needed, we support negotiation & compliance—always legally and with a clear audit trail.
Yes. We produce insurer-ready incident reports with a defensible timeline, scope, likely entry path, exfiltration assessment, actions taken, and chain-of-custody. We can join the adjuster call, map our findings to your carrier’s forms, and provide GDPR/NIS2 notifications where required. Final acceptance always depends on the policy and carrier, but our packages are designed to speed up approvals and reduce back-and-forth.
MSPs keep IT running; they’re not built for evidence handling and incident triage. Insurer panels optimize claims, not necessarily speed & clarity for your business. We work alongside both: kick off in ≤2h, run forensic triage with chain-of-custody, coordinate safe containment, and deliver executive- and insurer-ready findings—without taking your environment hostage.
Because it turns chaos into fast, safe recovery. We cut downtime and limit damage while preserving evidence. Within ≤48h you get a forensic triage pack (timeline, likely entry path, scope, decrypt-vs-clean-restore decision, go-live criteria) so leadership can act with confidence. Result: controlled, verified restart—not guesswork.
