Telnet bruter for systems with no username like some video conferencing devices including anti-bruteforce-detection-and-mitigation
Herpa derp derp derp. We got tasked with auditing the video conferencing infrastructure (cisco devices - i forget the models, will come update this) and tools like hydra and brutus etc couldn't do the job. False positives for every ~3rd password attempt because the telnet daemon on these devices are modified to dissuade bruteforce login tools like beforementioned.
So I got this little silly telnet client from codeproject and modified it to deal with these funky daemons and still get some bruteforcing love.
Run using mono, Miguel FTW.
