Byte Flip mutates targeted byte ranges while respecting overall file length. It is ideal when you want the file to open - but misbehave - surfacing nuanced defects like off-by-one errors, glitchy renders, or schema drift.

When headers go bad, systems must fail fast. Header Tamper zeroes in on manifests, cross-reference tables, CRCs, and atom metadata so you can practice those critical failure paths under controlled conditions.

Need to practice ransomware recovery without detonating malware? Entropy Surge is your mode. It blasts targeted regions with high-entropy bytes so signature-based detection, backup validation, and forensic training all get realistic input.
