TheGentlemen ransomware operation has listed Glassdoor on its leak site, claiming it accessed the US-based employment platform's systems and data and threatening publication after a 172-hour countdown. The claim remains unverified: the group has not released samples, no independent evidence confirms a compromise, and SOCRadar identified only 25 stealer-log records containing consumer email addresses, not employee credentials or proof of a link to the alleged intrusion.
Tracked by Sophos as GOLD SHERWOOD, TheGentlemen operates a ransomware-as-a-service model that steals data, disables endpoint defenses and backups, and encrypts networks—sometimes within 24 hours. Observed intrusions commonly begin through exposed firewall-management interfaces, unpatched appliances, or stolen VPN credentials, then use legitimate accounts and RDP to expand access, establish fallback remote-control paths, weaken Microsoft Defender, terminate EDR tools, disable recovery services, and occasionally clear Windows logs.

TheGentlemen ransomware group added Glassdoor to its leak site and claimed it had obtained unauthorized access to the company's systems and data. The group set a 172-hour countdown threatening publication of alleged stolen data, though it released no samples and the claim remained unverified.
Sophos analyzed 15 incidents associated with TheGentlemen, tracked as GOLD SHERWOOD, and documented a double-extortion workflow involving data theft, defense and backup disruption, and encryption. The review found initial access through exposed or unpatched infrastructure and stolen VPN credentials, with the fastest observed deployment occurring in under 24 hours.

A new ransomware group known as **Gentlemen** has launched a series of attacks targeting organizations in at least 17 countries, employing a double extortion model that involves both data exfiltration and encryption. The ransomware, developed in the Go programming language, leverages advanced techniques such as Group Policy Object (GPO) manipulation and Bring Your Own Vulnerable Driver (BYOVD) tactics to disable security defenses and propagate laterally within corporate networks. Industries affected include healthcare, manufacturing, and insurance, with the group specifically focusing on medium to large enterprises. The malware requires a specific `--password` argument to execute, serving as an anti-analysis measure, and offers operators various command-line options to control its behavior and evade detection. Analysts have identified Gentlemen as one of the most active emerging ransomware threats of 2025, with rapid expansion across North America, South America, and the Middle East. The group’s sophisticated evasion and propagation methods, combined with its aggressive targeting of sensitive data, underscore the urgent need for enhanced monitoring and defensive measures in enterprise environments. The campaign’s use of double extortion ensures that even organizations with robust backup strategies remain vulnerable to data leaks and reputational damage if ransoms are not paid.

TheGentlemen ransomware group was linked to a string of newly reported intrusions affecting organizations in several countries and sectors, including **Senvest Capital** in financial services, **Euroscreen** in digital printing and projection technology, **CRASL Accounting Services** in the UK, **Roadvision Systems** in transportation software, **Babcock Africa** in engineering and critical infrastructure support, **Gfeller Treuhand** in Switzerland, and **San Carlo Gruppo Alimentare** in Italy. The incidents were disclosed through separate reports that described ransomware-related breaches or victim listings tied to the same actor, with most reports indicating compromises or discoveries clustered within a short period. Available reporting indicates TheGentlemen operates as a **dual-extortion** ransomware group, combining file encryption with data theft to pressure victims, and has previously been associated with techniques including **`T1486`** for data encryption for impact. Sector diversity among the reported victims suggests broad targeting rather than a single-industry campaign, spanning finance, accounting, logistics software, manufacturing-related technology, food production, and infrastructure-linked engineering. One report on Gfeller Treuhand said business operations were not disrupted despite the attack, while other notices characterized the events as ransomware-driven data breaches without releasing technical indicators or intrusion details.

The Gentlemen ransomware group has rapidly established itself as a significant threat actor since its emergence around July 2025, leveraging a Ransomware-as-a-Service (RaaS) model and advanced dual-extortion tactics. The group has claimed at least 48 victims within a three-month period, utilizing the XChaCha20 encryption algorithm to lock files and exfiltrating sensitive business data to pressure organizations into paying ransoms. Their operations are characterized by a combination of established ransomware techniques and innovative strategies, including the development of their own RaaS platform after experimenting with various affiliate models, which has enabled them to quickly adapt to new attack vectors and maintain persistence against targeted organizations. Threat intelligence reports highlight that The Gentlemen's data leak site is active, and the group has demonstrated a willingness to publish stolen data if ransom demands are not met. Their evolution from testing other ransomware platforms to building a proprietary service underscores their technical sophistication and intent to scale operations. Security professionals are advised to monitor for indicators of compromise related to The Gentlemen and to ensure robust data protection and incident response measures are in place to mitigate the risk posed by this rapidly evolving ransomware group.
