Actor is utilizing uncertified "shadow" domains to execute Adversary-in-the-Middle (AiTM) attacks. By avoiding SSL/TLS certificates entirely, the infrastructure stays invisible to automated certificate monitoring tools.TECHNICAL ANALYSISZero-Cert Stealth: The absence of certificate data on email.mime.audio is a deliberate evasion tactic. It prevents the domain from appearing in public certificate databases, allowing the "fb hacker" proxy to operate in total darkness.Session Interception: Traffic is routed through the 104 IP space via HTTP. This allows the attacker to strip encryption and harvest session cookies and MFA tokens in plaintext before they ever reach the legitimate service provider.Library Mimicry: The mime.audio naming convention is designed to trick system admins into thinking the traffic is legitimate Python or email-handling library activity rather than an external exfiltration attempt.
