Description

This is a bit of a tougher CrackMe, you don't have to write a keygen but it would be cool if anyone did. Any feedback would be appreciated!

jnappdev on 2024-07-31 07:09: I'm maybe a beginner, but I can solve many other problems. However this one seems impossible. The string value constantly changing. Please give me a hint.

flcksr on 2024-07-31 21:23: @jnappdev best advice i can give is that it's probably easier to write a keygen than it is to patch

mebal on 2024-08-02 22:29: Was able to patch it by setting 00007FF6CDEA207A to NOP, just after the test al,al. UPX packer was used, some sort of integrity checks also exist as application does not run after being unpacked by the upx decompress tool. By using a runtime debugger, you can fiddle with it well

dev0 on 2024-08-05 09:23: @flcksr What do have against 4? Haha. Another good one. Really cool programming on the GUI image. You are really good and it seems you are having a bit of fun with these. Thank you!

nignog on 2024-08-23 23:31: im currently stuck, there is a function that gets called and it outputs to a pointer "key invalid/valid", there is some conditions that need to be met inside this function to print valid, but i cant figure out how. it seems that some checks are junk.
