The results of the F-Secure Reverse Engineering Challenge Compo can now be found at Khallenge.com.

Our three top prizewinners are: Kaspars Osis - Latvia; Igor Skochinsky - Belgium; Pasi Parviainen - Finland. They won, in the order named: a 60GB iPod, a Sony PSP, and an iPod Nano.

Two additional winners chosen from the correct answers to the third challenge are Anssi Kolehmainen and Kyynaama/Deviate of Finland. They'll be invited to lunch here at our Helsinki Labs.

Please heap ample incentives onto Otto to make sure he stays on the side of the "Good Guys" -- I would *hate* to have to deal with a piece of true malware written by him. Thanks for the good fun!"

Otto is genuinely a good guy, so no worries there we think.

The three challenge programs each used different tricks. The last/third made a virtual code maze that you had to maneuver through. Alexander Sotirov had the coolest solution to this; he actually drew a picture of the maze in order to solve it. Nice one Alexander! Although you didn't finish early enough to qualify for prizes, we'll send you a tee shirt or something.
