Static breakdown for all three parts. Covered the XOR encryption part and the 64-bit unsigned math. It's more of a helping hand rather than a direct spoiler. |

zen003 |
This crackme asks for a New Year’s Resolution string and validates it using a custom checksum algorithm combined with simple anti-debug checks.
A full reverse engineering write-up and a standalone keygen are provided as attachments.

Detailed walkthrough of static analysis using objdump.
Explains the character-by-character comparison pattern in x86-64 assembly.
Covers: reconnaissance with file/strings, reading cmp/jne instructions, hex to ASCII conversion.
Includes explanation of registers (rax, eax, al) and lessons learned for beginners. |

DRS_Steel |
Static analysis using objdump. Identified 3 checks in main():
1. argc == 2 (need exactly 1 argument)
2. strlen(password) == 10 (0xa in hex)
3. password[4] == '@' (0x40 in hex)
Valid password format: XXXX@XXXXX (10 chars, '@' at index 4)
Example: test@psswd → flag{test@psswd} |

SenorGPT |
Windows x86-64 C/C++ console crackme. Traced the password-handling path through std::string helpers in x64dbg and found that the apparent stack constant (`a#l67’gdb`) is a decoy; the real key is computed deeper in the transformation flow. Final password: `4v9cbr217`. |

SenorGPT |
x86 assembler crackme. Traced the password path from `ReadConsoleA` into the validation routine and identified an 8-byte memcmp-style loop against a static byte table. The correct password is the exact 8-byte sequence `@CBEDGFI` |

SenorGPT |
Java roulette simulator. Decompiled with JADX and recovered a custom 16-bit PRNG used for win/loss. Brute-forced the PRNG seed from observed outcomes to predict future rounds, then used a betting strategy to grow balance until a 32-bit signed integer overflow flips it negative, satisfying the “win” condition. |

Windows x86-64 crackme. Traced string references (e.g., `"Enter PIN:"`) in x64dbg back into `main`, identified the numeric PIN check, and patched/bypassed the failure path to reach the success branch and recover the correct input - 8569. |
