Who Runs the Ransomware Group โ€˜The Gentlemen?โ€™

10 June 2026 at 14:03

A cybercrime group known as The Gentlemen has emerged as the second most active ransomware gang by victim count, rapidly attracting a talented pool of hackers through an aggressive recruitment strategy that promises affiliates 90 percent of any ransom paid by victims. This post examines clues pointing to a real life identity for the administrator of The Gentlemen ransomware group.

Experts at the security firm Check Point Software have been closely covering exploits of The Gentlemen, a so-called โ€œransomware-as-a-serviceโ€ (RaaS) offering that pays affiliates handsomely to help spread the groupโ€™s malware.

โ€œA 90/10 affiliate revenue split โ€” compared to the industry standard 80/20 โ€” is accelerating the groupโ€™s growth by attracting experienced operators from competing programs,โ€ the researchers wrote in April.

Check Point found The Gentlemen are the second most active ransomware group by victim count so far this year, claiming at least 332 published victims since the groupโ€™s inception in mid-2025 and more than 240 in 2026 alone.

According to Check Point, the group targets Internet-facing devices (VPNs, firewalls) as their entry point, and once inside moves quickly to encrypt entire networks within hours.

Check Point says the administrator and primary operator of the ransomware group uses the nickname Zeta88 on the Russian-language cybercrime forums, and that this individual was previously known under the moniker Hastalamuerte. Check Point noted that a breach of the groupโ€™s backend infrastructure made it clear that Hastalamuerte/Zeta88 is the person who assembles the locker and RaaS panel, manages payments, and is essentially the administrator of the entire program who receives 10 percent of all ransoms.

WHO IS HASTALAMUERTE?

The cyber intelligence firm Intel 471 shows that the user Hastalamuerte is a Russian and English speaking person who registered on almost a dozen cybercrime forums between 2019 and the present day, including Exploit, Breachforums, Ramp_V2, BHF, Raidforums, and Nulled.

Intel 471 reveals that Hastalamuerte registered on Breachforums in January 2025 from an Internet address in Izhevsk, the capital city of Russiaโ€™s Udmurt Republic. Likewise, the user Zeta88 signed up at the English-language cybercrime forum Breached in August 2022 from a different Internet address in Izhevsk.

Intel 471 finds Hastalamuerte registered on Raidforums in 2020 using the email address hastalamuerte1488@protonmail.com (1488 is a common combination of two numeric symbols associated with white supremacy). A lookup on this address at the open source intelligence service Epieos shows it is connected to an account at Apple and to a phone number ending in 04.

Epieos says that Protonmail address is also linked to a GitHub account under the username SantaMuerte. That account is marked private, but a history of this userโ€™s activity shows they are watching and developing a number of malware tools and exploits.

In April 2020, Hastalamuerte said on the crime forum Nulled that they could be contacted at the Telegram instant messenger name @hastalamuerte18, and the threat intelligence company Flashpoint finds this username is assigned the unique Telegram ID number 30907522 [full disclosure: Flashpoint is an advertiser on this blog].

The breach tracking service Constella Intelligence reports that Hastalamuerteโ€™s Telegram ID is connected to another username โ€” โ€œbu4vsโ€ โ€” and to the Russian phone number 79127650004. Pivoting on this phone number in Constella fetches multiple records from hacked Russian government databases showing it is assigned to one Alexander Andreevich Yapaev, a 36-year-old from Izhevsk.

Constella reveals that phone number was used to create an account at the Russian social media platform Pikabu under the name โ€œ4apai18,โ€ and shows Mr. Yapaev has signed up at a number of websites using the common surname Ivanov, or else โ€œChapaevโ€ (the numeral 4 is often used as shorthand for a โ€œchโ€ sound in Russian).

A search in Intel 471 for cybercrime forum members with the nickname SantaMuerte unearths an account by the same name created in 2020 on the Russian hacking forum Codeby. Intel 471 shows this user originally registered on Codeby with the not-so-subtle nickname Alexandr 4apaev.

Constella finds Mr. Yapaev regularly used the email address bu4vs@mail.ru. Meanwhile, Epieos shows this address is connected to a LinkedIn account for Alexander Yapaev, who lists himself as the head of B2B marketing at the company Uralenergo Udmurtia, one of Russiaโ€™s largest suppliers of electrotechnical and lighting products.

Mr. Yapaev did not respond to multiple requests for comment.

Nearly every time we publish one of these Breadcrumbs stories, readers are curious to know why it seems like so many cybercriminals from Russia apparently do little to hide their real life identities. The truth is that โ€” Russian or not โ€” most didnโ€™t exactly set out to be arch criminals, but instead got drawn into the scene gradually over several years as their skills broadened and sharpened.

Another important dynamic is that the Russian government generally either co-opts or ignores cybercriminal activity within its borders so long as the hackers do not steal from or attack Russian businesses and citizens. As a result, successful cybercriminals in Russia are usually insulated from prosecution and arrest by foreign law enforcement agencies provided they occasionally pay off the right people and do not travel abroad. And cybercriminals who intend to strictly adhere to those unwritten rules may (at least initially) be less concerned about covering their tracks online.

But the simplest explanation is that cybercriminals of all nationalities tend to make a number of basic operational security mistakes early in their careers, when they are less savvy and have far less to lose by their carelessness. A review of Hastalamuerteโ€™s early posts on the crime forums (circa 2019-2020) shows a relatively unsophisticated and low-skilled hacker still trying to learn the ropes and earn a positive reputation on these communities.

For example, in June 2020 Hastalamuerteโ€™s Telegram account joined a multi-month training program (@pntst) to learn how to use popular penetration testing tools, and their candid posts to this hacker training camp show Hastalamuerte struggling to use these tools effectively. A Google-translated record of Hastalmuerteโ€™s posts to @pntst is here.

Update, June 11, 10:23 a.m. ET:ย  The threat research group PRODAFT has released a detailed writeup on the history and current operations of The Gentlemen. PRODAFT said its findings match the same persona with โ€œhigh confidence,โ€ and found the administrator (Zeta88/Hastalamuerte) supplies affiliates with initial access directly, primarily Fortinet SSL-VPN credentials obtained through brute-force attacks or sourced from the groupโ€™s own leak database. They also discovered the administrator is using AI to develop and maintain the ransomware and associated tooling, as well as to assist with post-exploitation activity.

GitHub pulls pin on npm's auto-run scripts

10 June 2026 at 13:11
GitHub will change npm's defaults so the install command no longer runs scripts automatically, disabling a feature commonly exploited by malicious packages such as the notorious Shai-Hulud worm. Maintainer Leo Balter said: "Install-time lifecycle scripts are the single largest code-execution surface in the npm ecosystem. Every npm install runs scripts from every transitive dependency, so a single compromised package anywhere in your tree can execute arbitrary code on a developer machine or CI (continuous integration) runner." In npm 12, due July, three security-focused defaults are changing. Scripts configured for preinstall, install, or postinstall will no longer run unless explicitly permitted via allow-scripts. The --allow-git flag, which pulls dependencies from remote URLs, will default to off, closing an attack path where a malicious .npmrc file could override the Git executable and achieve arbitrary code execution. Finally, allow-remote will default to none, blocking dependency downloads from remote URLs entirely. It will still be possible to allow scripts to run via an allowlist in the package.json configuration file. This will be pinned to the installed version of a package by default. These are breaking changes, and Balter recommended developers run the commands to allow scripts for every currently installed package in a project that requires them. "This gets you protected against new, unexpected scripts immediately," he said. The next step is to review these packages and deny scripts for those where they are not needed. Some packages require script approval to function, including native modules that compile on install, testing tools like Playwright and Puppeteer (which fetch binaries via postinstall), and Electron, which wraps the Chromium browser engine for cross-platform desktop applications. These features have been available since npm version 11.10.0, released in February, but as opt-in flags rather than defaults. That version also introduced min-release-age, which blocks installation of package version newer than a specified number of days, designed as a safeguard against newly published malicious packages. Best security practice for developers using npm 11.16, the current version, is to set these flags on in .npmrc or via environment variables, which will also prepare a project for the changes in version 12. One annoyance is that the existing flag ignore-scripts does not support an allowlist, other than via an additional tool. The ignore-scripts setting will override allow-scripts, so developers will need to remove it, if set to true, to enable approved scripts to run. The allowScripts setting exists in npm 11 but is advisory only. Will this fix npm security issues? Unfortunately not. "Now all the malware can move from the install script to the module itself where it will inevitably still be run," said one developer. Another common view is that developers should use pnpm, which already has safer defaults than npm, including a minimum release age. There is consensus, though, that these changes do improve npm security and are long overdue. The pull request for this change includes the remark that "npm is the only remaining major package manager that runs dependency install scripts by default. pnpm v10+, Yarn Berry, Bun, and Deno all block them." ยฎ

Ivanti tells Sentry customers to patch now as critical bugs hit 10.0 and 9.9

10 June 2026 at 11:04
It's patch time for Ivanti customers again after the security shop disclosed another two critical vulnerabilities in one of its products. Both bugs affect Ivanti Sentry, a mobile gateway that forms part of its broader unified endpoint management platform. The first and worst of the two is CVE-2026-10520 (10.0), a max-severity vulnerability that allows a remote, unauthenticated attacker to execute code with root privileges. Flaws that allow root-level code execution without authentication are about as bad as vulnerabilities get, which explains the perfect-10 rating. The only saving grace is that, by the vendor's reckoning, no one has successfully exploited it in the wildโ€ฆ yet. Public disclosures tend to start a figurative countdown timer when it comes to attackers exploiting bugs, and although Ivanti gave little away about CVE-2026-10520 in its advisory, other researchers have already published breakdowns of the patch, offering clues as to how unpatched systems could still be attacked. According to watchTowr, the vulnerability stemmed from an exposed API running under Apache Tomcat. An attacker could feed the API a specially crafted message, which is parsed as a MICS configuration command and executed by the backend handler with root privileges. It looks like Ivanti fixed this by preventing this attacker-supplied string from being accepted, replacing it with a single, hard-coded command. It also updated the Apache configuration rules to block unauthenticated access to the affected endpoint. The second critical Ivanti Sentry vulnerability is tracked as CVE-2026-10523, and is scarcely less serious, carrying a near-maximum 9.9 CVSS. The authentication bypass bug allows remote, unauthenticated attackers to create admin accounts, granting themselves top privileges on an affected system. Customers are advised to address both security flaws immediately. They can upgrade to versions 10.5.2, 10.6.2, or 10.7.1. Ivanti's disclosure this week comes after it fixed two separate critical vulnerabilities affecting its Endpoint Manager Mobile (EPMM) in January. The bugs were both handed 9.8 CVSS scores and were exploited as zero-days. Even the Dutch data protection authority reported itself to parliament after attackers breached it as part of the pre-patch exploits. ยฎ

Your Automated Pentest Looks Clean. See What It Missed in This Expert Webinar

Your pentest report looks clean. That might be the problem. Run automated pentesting long enough, and the new findings start to dry up. By the third or fourth run, fewer issues appear. The report looks stable. Leadership reads "stable" as "secure." It usually isn't. The work slows down. The risk does not. That gap is what a The Hacker News webinar with Picus Security sets out to close. Autumn
