Description
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.
How GTK Cyber trains on this
GTK Cyber's hands-on training programs cover detection engineering across the MITRE ATT&CK framework, including the Command and Control tactic this technique falls under. Our practitioner-led courses focus on building real detections, not just memorizing technique IDs.
