Found a website and a forensics contest yesterday quite by accident. I was waiting for somebody before going out for the night and I thought this might be a little fun while I waited. Now the contest had closed and

Earlier we looked at how you can extract a list of all the $CFG variables in your Moodle code. Now that’s not of much use! We need to know where in the code all these variables hide. I feel some spooky awk a

From time to time things tend to go wrong and systems tend to go crazy. Sometimes these errors are more of nuisance than anything else, an intermittent annoyance you’d prefer not to investigate — trawling through logs is a pain in

Over at the Honeynet Project they used to run security competitions which were quite a bit of fun. I remembered one in particular which I looked at but hadn’t completed. It dealt with the forensic investigation of a floppy disk. I was tinkering
