lol they have been useful for years son just because YOU never found a use for them doesn't mean noone else has :) ________________________________ From: Christian Sciberras [mailto:uuf6429 () gmail com] Sent: 4. februar 2010 13:00 To: Anders Klixbull Cc: Valdis.Kletnieks () vt edu; full-disclosure () lists grok org uk Subject: Re: [Full-disclosure] anybody know good service for cracking md5? Uh, in the sense that they are finally becoming actually useful...

Actually dictionary attacks seem to work quite well, especially for common users which typically use dictionary and/or well known passwords (such as the infamous "password"). Another idea which seems to be cropping in, is the use of hash tables with a list of known passwords rather then dictionary approach. Personally, the hash table one is quite successful, consider that it targets password groups rather than a load of wild guesses. Cheers.

Given enough hardware and a specified md5 hash, one could at least hypothetically find an input text that generated that hash. However, that may or may not be as useful as one thinks, as you wouldn't have control over what the text actually *was*. It would suck if you were trying to crack a password, and got the one that was only 14 binary bytes long rather than the one that was 45 printable characters long. ;) Having said that, it would take one heck of a botnet to brute-force an MD5 has in 1 or 2 days. Given 1 billion keys/second, a true brute force of MD5 would take on the order of 10**22 years. If all 140 million zombied computers on the internet were trying 1 billion keys per second, that drops it down to 10**16 years or so - or about 10,000 times the universe has been around already. I suspect they're actually doing a dictionary attack, which has a good chance of succeeding in a day or two. _______________________________________________ Full-Disclosure - We believe in it.
