ShareThis data breach: 41.0M accounts exposed
Severity: high · Patch status: no-fix-needed · Since 2019-03-03
In July 2018, the social bookmarking and sharing service ShareThis suffered a data breach. The incident exposed 41 million unique email addresses alongside names and in some cases, dates of birth and 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. The data was provided to HIBP by dehashed.com. Exposed data: dates of birth, email addresses, names, passwords. The breach dates from Jul 9, 2018; Have I Been Pwned loaded it on Mar 3, 2019.
What to do
- If you had a ShareThis 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.
