Detection Method: Archive analysis
Archive analysis is the process of unpacking compressed files like ZIPs, RARs, or TARs to find threats hidden inside. Attackers often bury malicious payloads in multiple layers of archives to bypass basic scanning. This method digs into those layers to expose what’s really inside.
Security systems use recursive unpacking to detect things like:
Scripts or executables hidden in nested ZIPs
Macro-enabled documents disguised inside archive chains
Encrypted files used to evade detection
For example, an attacker might send a ZIP file that contains another ZIP, which holds a Word document with malicious macros. Archive analysis unpacks each layer and inspects the contents individually.
