Dynamically creates script elements, potentially loading external malicious code.

Creates functions from strings, similar to eval(), often used to hide malicious code.

Listens for keyboard events, a common technique used by keyloggers.

Reads or writes to localStorage, which may contain sensitive site data.

String with entropy 6 bits — may be encoded/encrypted data
