| Algorithm | Description | Typical Effect | |-----------|-------------|----------------| | | Replaces random bytes with pseudo-random values (0x00–0xFF). | Visual artifacts, missing sections, CRC errors. | | Truncation | Deletes a specified number of bytes from the beginning, middle, or end. | Incomplete headers → file type detection fails. | | Bit Flipping | Inverts bits at specific offsets (e.g., XOR with 0xFF). | Subtle corruption, often undetected by checksums. | | Chunk Shuffling | Rearranges data blocks without altering total size. | Logic errors, broken references, infinite loops in parsers. | | Header Corruption | Specifically targets magic bytes (e.g., %PDF or FF D8 FF ). | Immediate rejection by file command or OS. | 4. Review of Existing Generators Several tools exist, ranging from simple scripts to advanced fuzzers: with open(input_path, 'rb') as f: data = bytearray(f

file_size = len(data) num_corruptions = int(file_size * corruption_ratio) | Incomplete headers → file type detection fails
