Country of Origin
Clockwork Spider is believed to operate from the Russian Federation, as indicated by credible classifications from threat intelligence sources; however, specific attribution remains somewhat limited.
Members
The size and member composition of Clockwork Spider are unknown. Any insight into operational roles or individual aliases is lacking within publicly available intelligence sources.
Leadership
At present, no names, aliases, or identifiable leadership details for Clockwork Spider have been publicly revealed. Information about their organizational structure remains obscure.
Tactics
Clockwork Spider’s primary goals are financial gain through the theft of banking credentials and the manipulation of financial transactions. They specifically aim to intercept or redirect funds via compromised systems.
Techniques
They extensively use malicious root certificates to manipulate victim systems, allowing man-in-the-middle (MiTM) attacks to intercept encrypted HTTPS communications. Deploying the Retefe malware is their signature method for executing these operations. This malware can modify browser trust settings, redirect network traffic, and harvest sensitive credentials.
Procedures
Clockwork Spider’s procedures utilize a combination of Retefe payloads and rogue certifications to proxy victim traffic through their controlled infrastructure. This model enables undetected credential theft and fraudulent redirections. Details on their exact initial infection vectors, such as phishing campaigns or exploit kits, are less well-documented.

- Military Organizations (focus on NATO-aligned entities).
- Media Outlets and Journalists (especially those covering Kremlin-related topics).
- Critical Infrastructure (energy, aerospace, and defense).
- International Sporting Organizations (e.g., WADA).
- Political Groups (e.g., the Democratic National Committee).
