2x replace JZ with JMP
Steps I've done:
1) open downloaded binary in Ghidra debugger.
2) search "User_not_recognized." All fields
3) pressed Ctrl+E (show decompliler) and analyzed FUN_140019fa0
4) noticed two if/else for user/password ... thats where patches should be applied
user bypass
replace CTRL+SHIFT+G (Patch intstruction)
14001a0cb 74 74 JZ LAB_14001a141
with
14001a0cb eb 74 JMP LAB_14001a141
password bypass
replace CTRL+SHIFT+G (Patch intstruction)
14001a18e 0f 84 81 JZ LAB_14001a215
00 00 00
with
14001a18e 48 e9 81 JMP LAB_14001a215
00 00 00
Done
Export modified exe and run =)

The crackme uses a 4x4 matrix lookup system where input pairs `(row, column)` access specific values that must sum to zero. The key gen I wrote generated 6 solutions |

Decompiling the main function shows a line where user input is compared to a hard-coded integer. Converting that integer into decimal form provides the answer! :) |

The program takes input twice, transmuting the first and checking if it's equal to the secondary input. Decompiling the program reveals simple arithmetic in the main function, which can be used to predict the required secondary input.
My write-up is longer than the others, but I hope it's still helpful! |
