Automated windows hash grabbing.

•2011/05/12 • Leave a Comment

I was playing around with ophcrack this week which is included in the katana suit. I’d recommend looking into both of these if you’re never heard of them, anyway, ophcrack has a live boot cd that boots directly into a LM and NTLM password cracker, dumps the hashes from the local machine and starts cracking with some rainbow tables.

It works fairly well but could be a lot better, for one the live distro they use is real bloated considering all it does is crack passwords, secondly they could have made saving the results a lot easier. The only thing I found real novel was dumping the hashes automatically, for your enjoyment here’s a bash script that goes through all NTFS drives and tries to dump the hashes 🙂

Network topology plotting with bash and graphviz.

I was looking for a way to map the routing between me and a bunch of hosts in Linux but couldn’t find a program I liked. The nice thing about Linux though is the ease that you can put something together with other tools. Here’s a simple bash script that parses tcptraceroute output and graphs it using graphviz, enjoy.

I saw a CCC talk a while back about reverse engineering IC’s (link, recording), it sounded fairly complicated for a hobbyist but I thought I’d give it a try. All I was hoping for was to get some decent pictures and didn’t really care about reversing the design. Continue reading ‘Boiling chips in tree sap.’

In an earlier post I got a cheap mag stripe reader working with the bus pirate and started dumping some cards. Continue reading ‘Student ID magstripe disected.’

Magstripe reverse engineering using the Bus Pirate

I recently got a hold of a magstripe reader someone threw out, the problem was that I couldn’t find any info on the unit, opening it up I found a serial number that was in the range of other readers but no specifics.

GTK+ turns out to be remarkably simple to use but getting it set up for devc++ was giving me some problems so I’ll give a brief tutorial.
