Threat Actor Profile
Carbon Spider
Carbon Spider stands as one of the most sophisticated and adaptable financially motivated cybercriminal groups operating today. Known by multiple aliases including FIN7, GOLD NIAGARA, and ITG14, this Eastern European threat actor has evolved from point-of-sale thieves to ransomware operators since their emergence around 2013-2015.
Threat Actor Profile
Carbon Spider
Country of Origin
Carbon Spider is believed to originate from Eastern Europe, with most security assessments pointing to the Russia-aligned criminal ecosystem. While their exact geographical base remains uncertain, their operational patterns and tactics align with established Eastern European cybercriminal networks.
Members
Carbon Spider operates as a sophisticated criminal organization with an estimated membership that fluctuates based on operational needs. The group employs a project-style organizational structure and maintains strict vetting processes for affiliates. Their size and exact membership numbers remain unknown, but the group has demonstrated the capability to recruit skilled operators through deceptive means, including using legitimate-appearing front companies for recruitment purposes.
Leadership
The leadership structure of Carbon Spider remains largely unknown to the public. However, law enforcement actions in 2018 resulted in the arrest of several high-ranking members, including individuals associated with their front company "Combi Security." These arrests led to convictions and prison sentences for key operatives, though the group's core leadership structure has never been fully exposed.

Tactics
Carbon Spider's primary objective centers on financial gain through multiple revenue streams. Initially focused on payment card data theft from point-of-sale systems, they later pivoted to big-game hunting and ransomware operations targeting larger corporate victims for substantial payouts.
Techniques
The group employs sophisticated social engineering campaigns, often using fake job offers and front company recruitment tactics. They leverage living-off-the-land tools, custom malware loaders, and red-team tools like Cobalt Strike to maintain persistence and move laterally through compromised networks.
Procedures
Carbon Spider typically initiates attacks through spearphishing attachments containing malicious documents with macro payloads. They exploit compromised credentials, stolen VPN access, and RDP vulnerabilities to gain initial access. Once inside networks, they deploy custom point-of-sale malware, bespoke loaders, and have been associated with ransomware families including DarkSide and connections to BlackMatter operations.

Notable Cyberattacks
The group's most significant operations include their extensive point-of-sale compromises across the United States, which led to major DOJ prosecutions. More recently, security vendors have attributed the operation of the DarkSide ransomware-as-a-service (RaaS) platform to Carbon Spider. This connection gained widespread attention due to the Colonial Pipeline ransomware incident, though attribution relationships in ransomware ecosystems remain complex and sometimes contested among security researchers.
Law Enforcement & Arrests
In 2018, the U.S. Department of Justice announced significant law enforcement action against Carbon Spider, resulting in indictments and arrests of several alleged group members. These actions specifically targeted individuals associated with the "Combi Security" front company used for recruitment and operational cover. Subsequent legal proceedings have resulted in convictions and prison sentences for high-level members, though t
