![]() For this part, I had to dive in the main flow of the serial number check mentioned above. This option is usually better because it also grants any other features that the full version has and the trial doesn't. This pitfall made me stick with the other option - playing with the serial number check such that I will get the full version. Turns out that the answer is not that much because apart from expiring the trial, nothing else happens. I always research on a disconnected virtual machine so I wasn’t afraid that anything would be sent, but it was still interesting to see how much effort the developers put on security. When seeing this, I was courious to see if any data about the cracker (me) is sent to the company. If it is, a red flag is raised and saved in the program and the trial automatically expires. The problem is - Turns out the developers added a security check that the maximum days left is not bigger than 30 days. Side note-I totally forgot about the tampered clock message at this point. A short and simple permissive license with conditions only requiring preservation of copyright and license notices. Now - everytime it will calculate the number of days left it will be 9999. iDone/010-Editor-Keygen is licensed under the MIT License. This was definitely a vector for further research - should I find the place this DS is stored and manipulate it? Reversing this DS got me to an interesting part in the code flow: Turns out that the developers of the program decided they want one big global class that will save all the variables and also load them.

While reverse engineering the routines I had some beautiful insights about the way the programmers of 010 decided to design the code: Main data structure Playing with the memory leading to conclusions Lucky for me, when pressing the “Check Licence” in 010 Editor trial version, I got to one of my breakpoints.Īfter catching a breakpoint starts the interesting part of Reverse engineering the flow and understanding the authors intentions according to the code. This part reminds me of playing at the casino - you start debugging the program hoping that one of you BPs catches. DebuggingĪt this part, it is safe to say I have enough knowledge about interesting parts of the flow and we can start the dynamic analysis. The start of this function is definitely another useful place to place a breakpoint in. ![]() In this flow, a password is being checked and something happens if it is accepted and passes all the check - but we will leave that part to the dynamic analysis.
