[FIN7](https://attack.mitre.org/groups/G0046) is a financially-motivated threat group that has been active since 2013. [FIN7](https://attack.mitre.org/groups/G0046) has targeted the retail, restaurant, hospitality, software, consulting, financial services, medical equipment, cloud services, media, food and beverage, transportation, pharmaceutical, and utilities industries in the United States. A portion of [FIN7](https://attack.mitre.org/groups/G0046) was operated out of a front company called Combi Security and often used point-of-sale malware for targeting efforts. Since 2020, [FIN7](https://attack.mitre.org/groups/G0046) shifted operations to big game hunting (BGH), including use of [REvil](https://attack.mitre.org/software/S0496) ransomware and their own Ransomware-as-a-Service (RaaS), Darkside. FIN7 may be linked to the [Carbanak](https://attack.mitre.org/groups/G0008) Group, but multiple threat groups have been observed using [Carbanak](https://attack.mitre.org/software/S0030), leading these groups to be tracked separately.(Citation: FireEye FIN7 March 2017)(Citation: FireEye FIN7 April 2017)(Citation: FireEye CARBANAK June 2017)(Citation: FireEye FIN7 Aug 2018)(Citation: CrowdStrike Carbon Spider August 2021)(Citation: Mandiant FIN7 Apr 2022)(Citation: BiZone Lizar May 2021)

[FIN13](https://attack.mitre.org/groups/G1016) is a financially motivated cyber threat group that has targeted the financial, retail, and hospitality industries in Mexico and Latin America, as early as 2016. [FIN13](https://attack.mitre.org/groups/G1016) achieves its objectives by stealing intellectual property, financial data, mergers and acquisition information, or PII.(Citation: Mandiant FIN13 Aug 2022)(Citation: Sygnia Elephant Beetle Jan 2022)

FIN11 is a well-established financial crime group that has recently focused its operations on ransomware and extortion. The group has been active since 2017 and has been tracked under UNC902 and later on as TEMP.Warlok. In some ways, FIN11 is reminiscent of APT1; they are notable not for their sophistication, but for their sheer volume of activity.(FireEye) Mandiant has also responded to numerous FIN11 intrusions, but we’ve only observed the group successfully monetize access in few instances. This could suggest that the actors cast a wide net during their phishing operations, then choose which victims to further exploit based on characteristics such as sector, geolocation or perceived security posture. Recently, FIN11 has deployed CLOP ransomware and threatened to publish exfiltrated data to pressure victims into paying ransom demands. The group’s shifting monetization methods—from point-of-sale (POS) malware in 2018, to ransomware in 2019, and hybrid extortion in 2020—is part of a larger trend in which criminal actors have increasingly focused on post-compromise ransomware deployment and data theft extortion. Notably, FIN11 includes a subset of the activity security researchers call TA505, Graceful Spider, Gold Evergreen, but we do not attribute TA505’s early operations to FIN11 and caution against using the names interchangeably. Attribution of both historic TA505 activity and more recent FIN11 activity is complicated by the actors’ use of criminal service providers. Like most financially motivated actors, FIN11 doesn’t operate in a vacuum. We believe that the group has used services that provide anonymous domain registration, bulletproof hosting, code signing certificates, and private or semi-private malware. Outsourcing work to these criminal service providers likely enables FIN11 to increase the scale and sophistication of their operations.

[FIN10](https://attack.mitre.org/groups/G0051) is a financially motivated threat group that has targeted organizations in North America since at least 2013 through 2016. The group uses stolen data exfiltrated from victims to extort organizations. (Citation: FireEye FIN10 June 2017)

FireEye first identified this activity during a recent investigation at an organization in the financial industry. They identified the presence of a financially motivated threat group that they track as FIN1, whose activity at the organization dated back several years. The threat group deployed numerous malicious files and utilities, all of which were part of a malware ecosystem referred to as ‘Nemesis’ by the malware developer(s), and used this malware to access the victim environment and steal cardholder data. FIN1, which may be located in Russia or a Russian-speaking country based on language settings in many of their custom tools, is known for stealing data that is easily monetized from financial services organizations such as banks, credit unions, ATM operations, and financial transaction processing and financial business services companies.

Femwar02 is a previously unknown pro-Russian ransomware threat actor that emerged in early 2026, linked to a major cyberattack on Italy's Sapienza University of Rome in February 2026, which caused a full network shutdown and operational disruptions. The group deploys Bablock (also known as Rorschach), a next-generation ransomware strain first identified in 2023 that features fast hybrid encryption (curve25519 and hc-128), partial file encryption for speed, direct system calls to evade detection, and domain-wide propagation via Group Policy on Windows Domain Controllers. Bablock shares code similarities with LockBit 2.0 but incorporates elements from other families like Babuk and DarkSide, often delivered via encrypted payloads, DLL sideloading with tools like DarkLoader, and exploits such as those in Zimbra or phishing. Notably, the malware skips encrypting files written in Russian, reinforcing its pro-Russian alignment, with no prior attributions or campaigns documented before the Sapienza incident.

Fail0verflow is a hacking group known for exploiting vulnerabilities in gaming consoles, notably the Nintendo Wii and PlayStation 3.
