Quiet often people ask me to bruteforce a hash for them. My usual response after the obligatory; where did you get the hash from? is “I’ll run a few dictionaries against it unless you provide me with a charset and length!”

For those that don’t understand it needs to be made clear exactly what bruteforce cracking means.

Lets just say we have a four character pin that can only… Continue reading

So I used a test script made by atom a while back to create a bit of code that outputs a hash for a given password. It didn’t support stdin so I thought I would update it, and here it is.

Note: Don’t copy/paste the code, instead get it from here:

So you’ve got a hash and you want to crack it. We’ve already covered a quick way to get to a windows password here but in that example we simply used john the ripper to crack the password… but what if john is taking ages? Step in rainbow tables.

I wont go into detail of what Rainbow tables are as they are already well documented on the web but as… Continue reading
