Re: [ILUG-BOM] [OT] cyberoam client logon algorithm
by Amish Mehta 20 Dec '01

20 Dec '01

Hi, Probably I shouldnt post this here but this looks to be best source for good crackers. :-). Just last sunday i was trying to figure out how cyberoam client encrypts password, but I failed :-). Here is sample file attached, u can open in Excel as tab sepatated file and 'text' formatting of all fields instead of general formatting. Basically first field is timestamp and then each of passwords character is replaced by 3 digit number based on some algorithm. There is one more key probably used and I dont know if it is related to adaptor address. In my case its 00:50:BA:8D:42:F4. This exists in all authentication requests.(see sample) The 3 digit number seems to change with time as its the only thing changing, rest known keys remaining the same. If somebody wants to reverse engineer the client I can send them the exe(setup too) if its legal to do so(is it?). Once algorithm is known, I will try to come up with Linux client as early as possible. Thanks.

Distro Mania
by J. T. D'souza 20 Dec '01

20 Dec '01

Redhat is suing those who copy and sell RH distro's as RH. So watch out all u "el cheapos". However imho RH is entitled to protect it's brand name and must take to court those who distribute RH copies as RH in an attempt to hijack it's brand equity. But that would ironically make distros like AL legitimate and reduce RH's brand exposure (so generously being pushed by the guys who distribute copies). Besides the Pandora's box of trademarked Logos, screens, manuals etc. Haaappy Litigation :-)). http://www.newsforge.com/article.pl?sid=01/12/18/1741238&mode=nocomment AAAHHHA Debian. _________________________________________________________ Do You Yahoo!?
