| Step | What we did | Why it works | |------|--------------|--------------| | | strings → “flag?” and a readable string “midv536”. | Points to a hidden blob and a possible key. | | 2. Disassemble | Ghidra/IDA → decode_and_print function that XOR‑s a buffer with a byte from the midv536 string. | Reveals the exact algorithm used to hide the flag. | | 3. Locate offsets | The data blob starts at 0x402030 , the key at 0x402000 . | Needed for a script that extracts the correct bytes. | | 4. Decode | XOR each byte of the blob with the low‑byte of the key ( 0x6d ). | Restores the original plaintext. | | 5. Retrieve flag | The result is flagX0r_4nD_5h1fT_5oLVeD . | This is the flag to submit. | For a seamless connection to the outside world, the i
