Lawrence Abrams, reporting for Bleeping Computer:

Internet Archive’s “The Wayback Machine” has suffered a data breach after a threat actor compromised the website and stole a user authentication database containing 31 million unique records. News of the breach began circulating Wednesday afternoon after visitors to archive.org began seeing a JavaScript alert created by the hacker, stating that the Internet Archive was breached.

“Have you ever felt like the Internet Archive runs on sticks and is constantly on the verge of suffering a catastrophic security breach? It just happened. See 31 million of you on HIBP!,” reads a JavaScript alert shown on the compromised archive.org site.

The text “HIBP” refers to is the Have I Been Pwned data breach notification service created by Troy Hunt, with whom threat actors commonly share stolen data to be added to the service.

Hunt told BleepingComputer that the threat actor shared the Internet Archive’s authentication database nine days ago and it is a 6.4GB SQL file named “ia_users.sql”. The database contains authentication information for registered members, including their email addresses, screen names, password change timestamps, Bcrypt-hashed passwords, and other internal data.

As if that weren’t enough to make for a bad week for the Internet Archive — a seemingly irreplaceable stalwart resource of the web — they’re also under a DDoS attack. Jason Scott, archivist at Internet Archive, on Mastodon:

Someone is DDOSing the internet archive, so we’ve been down for hours. According to their twitter, they’re doing it just to do it. Just because they can. No statement, no idea, no demands.
