I won a book! Anyway, yesterday I remembered the contests Sploitcast runs, and went and had a look at the one they'd released last friday, and to my surprise found the one that had been released on the day I'd gone canoeing hadn't been solved, a couple of hours later: http://www.sploitcast.com/ (Scroll down to the News Section) I solved the challenge (by finding a copy of purchase_report.txt), and it seems I was the first. So now I get a free Syngress Publishing book.
I chose to get RFID Security by Frank Thornton, Brad Haines and John Kleinschmidt, which should be interesting once it gets shipped out to me.
If anyone is bored, I suggest they go try out the challenge (even though you won't win anything), its an interesting one.
Oh, and if anyone is subscribed to the RSS feed (I think there are a very small few) and you don't want to read about crap like this, just subscribe to the "Security (All)" feed, which won't contain anything other than security articles.
