polymorphic webshells
poly
A python script that generates polymorphic webshells.
Use it to encode your favourite shell and make it practically undetectable.
If no shell is specified with the -p arguement, the default shell in the /shells directory is used.
Supported webshells
| Webshell | |
|---|---|
| .php | |
| .asp | ( vbs ) |
| .aspx | ( c# ) |
Supported encoders
| Encoding | |
|---|---|
| b64 | base64 encoded text with random strings in random intervals |
| ord | ord() each character plus a random number |
| rnd | each character is mapped to another random character |
| rot | text is divided by a random number of rows, then rotated 90 degrees clockwise |

| Encoding | Detection rate |
|---|---|
| none | 41 / 56 |
| b64 | 0 / 52 |
| ord | 0 / 54 |
| rnd | 0 / 56 |
| rot | 0 / 56 |
Requirements :
Python 2.7
Notice :
With asp shells it is recommended to use the default shell. ( /shells/shell.asp )
Encoded aspx shells may not work on some servers.
Php works pretty much with every shell, on every server.
Rnd and rot encodings are not binary safe. ( may produce unprintable characters )
