opsec-aggressor

Aggressor script that gets the latest commands from CobaltStrikes opsec page and creates an aggressor script based on tool options.

Grabs latest commands from https://www.cobaltstrike.com/help-opsec and sets block/allow based on tool input.

Options of commands to block/allow are:

• API-only
• House-keeping Commands
• Inline Execute (BOF)
• Post-Exploitation Jobs (Fork&Run)
• Process Execution
• Process Execution (cmd.exe)
• Process Execution (powershell.exe)
• Process Injection (Remote)
• Process Injection (Spawn&Inject)
• Service Creation
