Armor is a simple Bash script designed to create encrypted macOS payloads capable of evading antivirus scanners. Below is an example gif of Armor being used with a simple Netcat payload.

A Netcat listener is started on port 4444. The "payload.txt" file is read and shown to contain a simple Bash one-liner that, when executed, will create a TCP connection between the target MacBook at the attacker's Netcat listener. Armor is used to encrypt the bash one-liner. Ncat is used to host the decryption key on the attacker's server. When the stager is executed in the target MacBook (not shown in the gif), the bash one-liner is decrypted and executed without writing any data to the harddrive. Ncat immediately terminates the listener after the key has been used. When the Netcat connection is established, the attacker has remote access to the target MacBook.

Admittedly, encrypting most macOS-specific payloads is overkill. This specific bash one-liner is capable of bypassing antivirus without the help of Armor. But this is just an exmaple. The same degree of obfuscation can be applied to sophisticated Python, Ruby, and Shell scripts designed to execute a variety of advanced attacks.
