Severity: high · Patch status: no-fix-needed · Since 2026-03-23
In around 2011, the now defunct RuneScape Boards forum (also known as RSBoards) suffered a data breach that was later redistributed as part of a larger corpus of data. The vBulletin-based service exposed 223k unique email addresses along with usernames, IP addresses and salted MD5 password hashes. Exposed data: email addresses, ip addresses, passwords, usernames. The breach dates from Dec 26, 2011; Have I Been Pwned loaded it on Mar 23, 2026.
What to do
- If you had a RuneScape Boards 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.
