Symmetric Cryptography - T1521.001 (bb4387ab-7a51-468b-bf5f-a9a8612f0303)

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, Blowfish, and RC4.
