Clockwork Spider TTPs
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.
