Description

PhantomGate: Your goal: find the correct serial key. Input format: XXXXX-XXXXX-XXXXX-XXXXX Example: ABCDE-FGHIJ-KLMNO-PQRST (this is NOT the answer) How to interact: Run phantomgate.exe in a terminal/cmd Enter your serial when prompted "Access Granted" = you solved it "Access Denied" = wrong serial This is original work created for educational RE purposes. No network connections. No external DLLs. Standalone exe. HINTS: 1. Do not trust anything or everything. 2. If it's too easy to do, you are heading in wrong direction. BEST OF LUCK :) HOLD TIGHT!!

liboxin on 2026-05-17 17:29: @AdminX PhantomGate v1.0 -- Reverse Engineering Challenge Enter serial (XXXXX-XXXXX-XXXXX-XXXXX): 4QJCG-P4R7Y-3VMY7-XRWHM [+] Access Granted! The gate yields. Well played, Reverser. Press ENTER to exit...

AdminX on 2026-05-18 10:24: @liboxin GGs, you have discord?

liboxin on 2026-05-18 11:54: @AdminX your crackme is fun, the information strings are encoded by a func, and decoding while running, and the core check func has VM check and Z3 symbol check and XXXXX-XXXXX-XXXXX-XXXXX format check, but luckily, I finally solved this, and I wrote a write-up here, and you can try to read it

AdminX on 2026-05-18 15:54: @liboxin Yes i've read your write up, it's actually good. and yes i added some checksums and lil bit freaky stuff to deflect the reversers but guess what? you can't deflect the pro ones. GGs

AdminX on 2026-05-18 15:56: @liboxin and if you don't mind can you share your discord or any social? i will be glad to discuss reverse engineer with you
