T1573.001 Symmetric Cryptography Mappings

Adversaries may employ a known symmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Symmetric encryption algorithms use the same key for plaintext encryption and ciphertext decryption. Common symmetric encryption algorithms include AES, DES, 3DES, Blowfish, and RC4.

Capability ID Capability Description Mapping Type ATT&CK ID ATT&CK Name Notes
action.hacking.variety.Evade Defenses Modification of the action (rather than the system, as in 'Disable controls') to avoid detection. related-to T1573.001 Encrypted Channels: Symmetric Cryptography
action.malware.variety.Backdoor or C2 Malware creates a remote control capability, but it's unclear if it's a backdoor for hacking or C2 for malware. Parent of 'C2' and 'Backdoor'. related-to T1573.001 Encrypted Channels: Symmetric Cryptography
action.malware.variety.C2 Malware creates Command and Control capability for malware. Child of 'Backdoor or C2'. related-to T1573.001 Encrypted Channels: Symmetric Cryptography
