🧬 File Signature Checker
Verify a file's true type by reading its magic bytes (file header). Detects files disguised with a fake extension.
🕵️ Forensic Note
Magic bytes (file signatures) are the first few bytes of a file that identify its true format, regardless of the extension. Attackers often rename executables (.exe) with safe extensions (.jpg, .pdf) to bypass basic security checks. This tool detects such disguises.
