against.py v-0.2 released – mass scanning and brute-forcing script for ssh
‘against.py‘ is a very fast ssh attacking script which includes a multithreaded port scanning module (tcp connect) for discovering possible targets and a multithreaded brute-forcing module which attacks parallel all discovered hosts or given ip addresses from a list.
Changelog v-0.2:
– prints kernel version after login
– optimized timings when cracking
– detection for key authentication
– false positive / small honeypot detection
– save found target ip addresses to file, -O option
– 127.x.x.x will be excluded when scanning for random ip addresses
– unsort found target ip addresses, because of sequential port scanning
– resolve ip address by given hostname
– stop attacks on target when keyboard-interactive is required
– set threads for port scanning, -s option
* Fixed handle list selection bug when disabling “Hide unnamed handles”
TODO :
– keyboard-interactive handler
– scan ip address ranges randomly
