jnth on 9:52 AM 08/26/2024: oh, sorry, forgot to check the file size. ignore my previous comment
newcracker on 9:04 AM 08/28/2024: Who can teach me how to crack it
Nicole.exe on 5:26 PM 09/01/2024: Cracked, i dmed you on discord
zekihvh on 10:28 PM 09/02/2024: A lot of ciphering (single way ciphering with english as base, you can guess how well that goes), a decent bit of anti-debugging, yet no integrity checks
nignog on 8:51 AM 09/07/2024: babi antidebug, u can run the cipher code to get out the strings
cadis on 8:09 PM 09/07/2024: Hello new here how can drag the .exe when its asks a password ? any clue please ?
survivalizeed on 10:44 PM 09/07/2024: Nice crackme. Next time i would suggest to make a more complicated obfuscation, as the password routine actually only checks the code in a very few lines of assembly.
That way your 1000+ lines of asm turned out to be like 20+ lines of asm to analyze. My suggestion would be to do some more pseudo shifts with the password to cause more confusion.
For some odd reason I wasn't able to use memory breakpoints... Could be anti-debugging but not too sure. Setting a first chance exception filter did the job for me :)

Ch4daev on 2:20 PM 09/09/2024: Good crackme. The password checking code looks very cumbersome because of a lot of embedded code from the std library, in particular the std::string implementation. Finding the password is very easy if you apply bp to the string decryption function, which is identical for both normal console messages and the password. Anti-debugging is not very difficult, I was very interested in the snippet that looks for int3 instructions in RWX memory regions, this seems very strange as usually the debugger does not change the protection to set a breakpoint, and even if it does it puts the memory protection back after a successful set breakpoint.
