XenocodeRCE Posted June 1, 2019 Posted June 1, 2019 you can dump using megadumper, if you suspend process to prevent anti dbg from running. result is : ConsoleApp1.exe 1.248 mb little xor on confuserexstring decryptor method (it stupid only 1 param out of 3 are usefull) : you need to patch a call method at EP (call to native dll) and you can debug and dump correct strings from memory, because it changes every time (not sure but i would say im 60% right)

MulaB Posted July 24, 2019 Posted July 24, 2019 (edited) Nice crackme you got here. To begin with I tried cleaning the code as much as possible but it still is very messy, so my approach was simply debugging the file and stepping trough the code. I made some small changes and now it returns something what seems like the actual "key". Result.rar Edited July 24, 2019 by MulaB Forgot to add the file.
