Disqus data breach: 17.6M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2017-10-06
In October 2017, the blog commenting service Disqus announced they'd suffered a data breach. The breach dated back to July 2012 but wasn't identified until years later when the data finally surfaced. The breach contained over 17.5 million unique email addresses and usernames. Users who created logins on Disqus had salted SHA1 hashes of passwords whilst users who logged in via social providers only had references to those accounts. Exposed data: email addresses, passwords, usernames. The breach dates from Jul 1, 2012; Have I Been Pwned loaded it on Oct 6, 2017.
What to do
- If you had a Disqus 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.
