Obfuscate or encrypt code
Obfuscation is the act of creating code that is more difficult to understand. Encoding transforms the code using a publicly available format. Encryption transforms the code such that it requires a key to reverse the encryption. 
Tactic: Adversary Opsec
DetectionDetectable by Common Defenses (Yes/No/Partial): Yes
Explanation: Detecting encryption is easy, decrypting/deobfuscating is hard.
Difficulty for the AdversaryEasy for the Adversary (Yes/No): Yes
Explanation: Various solutions exist for the adversary to use. This technique is commonly used to prevent attribution and evade detection.
