Windows Defender blocking payloads?

BadUSB payloads get blocked by Defender. How to avoid detection during authorized pentests?

[bad-antics]

AV evasion tips for authorized pentests:

1. AMSI Bypass - Add at start of PowerShell payloads

2. Obfuscation - Break up known signatures

• Split strings: $(chr(73)+chr(69)+chr(88))
• Base64 encode commands

3. Living off the land - Use built-in tools (certutil, bitsadmin)

4. Timing - Add delays so behavior analysis times out

5. Staged payloads - Download and execute in separate steps

For testing: Temporarily add exclusion in Defender settings, then re-enable after testing works.

Remember: Only use on systems you have authorization to test!
