Encrypted Channel
4 actors on record using it
Every mark is an actor ATT&CK records using this technique. Red ones also exploit a CVE in CISA KEV.
Open T1573 on attack.mitre.orgAdversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.
