Programming - Coverage-Guided Fuzzing
Mission
coverage-queue.jsonl is generated from the FLAG injected at startup. Order Base64 inputs by offset and XOR-decrypt with SHA-256(edge-0x5e7) to recover the flag.
Hints
Hint 1 Show
Inspect coverage-queue.jsonl and identify the target record
Hint 2 Show
order Base64 inputs by offset and XOR-decrypt with SHA-256(edge-0x5e7)
Hint 3 Show
Verify that the reconstructed value has FLAG{...} format
