One year ago, to the day, I posted YACoSTO. I explained how I reversed a program that “protects” data. This is one of my favorite posts, but it hardly gets any hits. I encourage you to read it, because this time, I focus on reversing the protected data rather than the program itself. You might learn a couple of new and simple techniques.
The binary tools I used for the YACoSTO post can be found here, I published them afterwards.
Contrary to what some of you might think, this is not a “I’m on holiday” post 😦 . We took a short cruise in June. My sister-in-law, a professional wedding film producer, shot this movie (YouTube) during our holiday, hires version here. Absolutely no malware, hacking, revering, … in the movie, just holidaying.
Oh, and BTW, until now, nobody ever asked me what YACoSTO means…
