Breach Breakdown: Internet Archive

31 Million Users Affected

What Organization Did Hackers Breach?

Hackers breached the Internet Archive, a nonprofit digital library renowned for its Wayback Machine, in October 2024. The organization serves as a cornerstone of digital preservation, hosting billions of archived web pages, books, audio recordings, and videos. The breach exposed user data tied to its core community—those who rely on its vast repositories for research, education, and cultural archiving. While the Internet Archive does not operate as a commercial platform, this breach highlights that even nonprofit institutions are vulnerable to cyber threats.

When Did the Internet Archive Data Breach Happen?

Hackers gained unauthorized access in October 2024, and the Internet Archive disclosed the breach on October 9. The site displayed a pop-up alerting visitors to the breach and directed them to Have I Been Pwned (HIBP), where users could check if their credentials had been compromised (bleepingcomputer.com).

What Information Did the Internet Archive Data Breach Expose?

The breach compromised a user authentication database containing 31 million unique records. Hackers stole the following data:

  • Email addresses
  • Screen names
  • Bcrypt-hashed passwords
  • Timestamps for password changes
  • Other internal data

The database contained data as recent as September 28, 2024, indicating when the hackers exfiltrated the information (bleepingcomputer.com).

Scope of the Exposure

Security researcher Troy Hunt, who operates Have I Been Pwned, confirmed that hackers exposed data from 31 million user accounts. These email addresses have been added to the breach notification service, allowing individuals to check if their data was compromised.

How Can Cyber Criminals Exploit the Stolen Data?

Credential Stuffing and Account Takeovers:

Hackers can target reused credentials in credential stuffing attacks, even though the passwords were hashed.

Phishing and Social Engineering:

Cybercriminals can use email addresses and activity data to craft phishing emails that impersonate notifications from the Internet Archive or related academic services.

Privacy Erosion and Doxxing:

Hackers can analyze activity logs and borrowing records to profile users’ interests, threatening their anonymity and digital freedom.
