Obtaining/cracking passwords remotely

Is it possible to use a password cracker (L0pht Crack 4) to obtain then crack passwords when remotely connected with telnet?

You may want to re-phrase your question to something like, "How can I prevent someone from using a password cracker remotely against my systems". This way you would likely get answers rather than neg's.

Thanx for not answering my question.

Sorry kid, you were warned, hope you enjoyed your 'short' stay at AO.

LuaLua is gonna get :ubergun:
This is a security site DONT ask hacking questions. Read the "read before you post" tutorial.

Hold on a sec people

I just asked a simple question, not a hacking question and im getting flam3d for it
I just want to learn, and the only way to learn is to ask questions!

Im sorry if ive offended anyone and ill not ask any more questions.

Thanx again.

LuaLua -- The question you asked implies that you would be illegally obtaining encrypted passwords to crack with the intention of compromising a system. I think that's why DjM was warning you to quickly rephrase that question to one that does not suggest illegal activities. Most folks here will not help you commit a crime.

If, however, you're interested in how to protect against such an attack, I would recommend using shadow passwords (mostly used these days anyway).

One more thing. The word 'telnet' makes the hairs back on my neck stand up. It's an antiquated and thoroughly insecure protocol. If you're not using ssh, you really should be!

:bigsmile:

What would be the point of a security website if it were used to help people crack or hack?

Thanx for the not flaming me Roswell.
I am not interested in hacking/cracking or whatever.
Im in the IT business but would like to broaden my kn0wledge by learning the security side of things, and the best way to learn is from others!

Once again sorry for posting the dumb question but i am as the title says a NEWBIE

It's ok LuaLua we all forgive you.
