Once again, F-Secure is supporting the T2 Information Security conference, to be held in Helsinki in September. And once again, free tickets to the conference are given to people completing the T2 CHALLENGE.
As last year, your mission (should you decide to accept it) is to reverse engineer or crack a Windows EXE file, which is available for download in here.
The challenge program - written by Jarkko Turkulainen from our lab - contains an assortment of nasty tricks. Breaking it won't be easy. Good luck. The first one to crack the challenge gets a free ticket to the conference, and another ticket is drawn among others who complete it.
Last year, the challenge program was downloaded more than 50,000 times. Less than 30 cracked it.
