April 13, 20205 yr Solution Very mature choice for username and password. 😑 Spoiler user: HattanisGAy pass: Noone ISgay Tutorial: Spoiler No need for unpacking. Everything is visible in the debugger: Tutorial using WinDBG: Run program without debugger Attach WinDBG, load SOS extension. Break execution, !dumpheap -strings. Create a copy of the output Continue execution, Enter random username and pasword. Break execution, !dumpheap -strings again. Notice string "HattanisGAy" is added. Must be username repeat previous two steps, but this time fill in correct username. Observe password. Tutorial using dnSpy: Run program without debugger Attach dnSpy. Think of a username (e.g. "washi") and password (e.g. "1234") combi Add breakpoint on String.Equals(string a, string b) with condition a == "washi" || b == "washi" Continue execution, enter random user-pass Breakpoint hits, observe correct username. Do the same with password. Edited April 13, 20205 yr by Washi Added missing words.
