Wayback Machine

The Internet Archive's service storing historical snapshots of websites, useful for finding removed content.

Definition

Testers use archived pages to discover old endpoints, removed files, leaked information, previous technologies and forgotten parameters. Tools like waybackurls automate extracting historical URLs. It is a passive OSINT source.

Example

Finding an old /backup/ link in a 2019 snapshot that still returns a database dump.

Exam tip

Archived content can reveal endpoints still live but no longer linked.
