Extranet/Intranet Dictionary Cracker in VB
(Page 1 of 3 )

I wrote this Cracker to gain entry into a client’s Intranet, and did so in 2 minutes with a basic dictionary of 100 words (cat, dog, admin, etc.).

The purpose of this article is to stun you into taking the necessary steps to protect your site. I was prompted to write this article because of posted literature exposing ebay.com susceptibility.

If you are looking for a Cracker engine, IT IS NOT HERE. I have removed the communication and word library elements, but the architecture and code are in place so that it is easy to see how entry is gained to your site.

Despite the abundance of security publications, advertisements and television hype describing most unauthorized entry to computers as gained via network vulnerabilities, system flaws, bugs, loopholes, and buffer overflows, the weakest point of any network is the user. Specifically, the user uses a UID of ‘admin’ and PW of ‘password’ or other common words. Truly, this is incredibility widespread.
