MyHeritage data breach: 92.0M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2019-02-20
In October 2017, the genealogy website MyHeritage suffered a data breach. The incident was reported 7 months later after a security researcher discovered the data and contacted MyHeritage. In total, more than 92M customer records were exposed and included email addresses and salted SHA-1 password hashes. In 2019, the data appeared listed for sale on a dark web marketplace (along with several other large breaches) and subsequently began circulating more broadly. Exposed data: email addresses, passwords. The breach dates from Oct 26, 2017; Have I Been Pwned loaded it on Feb 20, 2019.
What to do
- If you had a MyHeritage 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.
