Advanced archives can contain "Zip Bombs" (decompression bombs) designed to crash a system by expanding a small file into terabytes of junk data upon extraction, overwhelming the disk I/O and CPU. 4. Mitigation and Response

Forensic tools check the "Magic Bytes" ( 50 4B 03 04 ). If a file named fwifqn.zip lacks these headers, it is likely a different file type (e.g., an executable) disguised with a .zip extension to evade simple email filters. 3. Execution and Behavioral Risks fwifqn.zip
