Adeko 9 — Crack 56

| Tool | Purpose | |------|---------| | | Verify that the binary is not packed. | | x64dbg (or OllyDbg ) | Dynamic debugging, breakpoints, watch registers. | | Ghidra 10.2 | Static disassembly & de‑compilation. | | Strings | Quick view of embedded literals. | | Python 3.10 | Write a small key‑generator script (optional). | | procmon / Process Explorer | Observe any hidden anti‑debug syscalls. | Tip: Run the binary once under a debugger to confirm the presence of anti‑debug checks (e.g., IsDebuggerPresent , CheckRemoteDebuggerPresent ). If they crash the program, we’ll patch them out later. 3. Static Analysis 3.1. Basic PE info File Type: PE32+ (64‑bit) Entry point: 0x140001010 Sections: .text 0x2000 (code) .rdata 0x1000 (read‑only data) .data 0x0800 (mutable data) .rsrc 0x0400 (resources – contains UI strings) The .rdata section contains the two strings we’ll see in the UI:

// 3. The valid serial is the one whose hash equals the constant 0x56C9A4F2 return (h == 0x56C9A4F2); Adeko 9 Crack 56

If we denote the post‑transform byte as b_i = t(i) , the CRC algorithm is applied to the sequence b_0 … b_8 . | Tool | Purpose | |------|---------| | |

The program uses the insecure gets_s but limits to 63 characters – no overflow. The real work is in check_serial . 3.3. The serial‑checking routine In Ghidra the function is named check_serial (address 0x140001560 ). Its decompiled pseudo‑code (after some renaming) looks like this: | | Strings | Quick view of embedded literals
