Severity: high · Patch status: no-fix-needed · Since 2025-05-08
In July 2016, the now defunct free online games list website OnRPG suffered a data breach that was later redistributed as part of a larger corpus of data. The incident exposed just over 1M email and IP addresses alongside usernames and passwords stored as salted MD5 hashes. Exposed data: email addresses, ip addresses, passwords, usernames. The breach dates from Jul 1, 2016; Have I Been Pwned loaded it on May 8, 2025.
What to do
- If you had a OnRPG account, change its password and the password of any other account that reused it.
- Turn on multi-factor authentication wherever it is offered.
- Check whether your addresses are in this breach at https://haveibeenpwned.com.
- Expect targeted phishing that quotes the leaked details; verify any unexpected contact out of band.
