Severity: high · Patch status: no-fix-needed · Since 2016-09-11
In September 2016, the paid-to-click site ClixSense suffered a data breach which exposed 2.4 million subscriber identities. The breached data was then posted online by the attackers who claimed it was a subset of a larger data breach totalling 6.6 million records. The leaked data was extensive and included names, physical, email and IP addresses, genders and birth dates, account balances and passwords stored as plain text. Exposed data: account balances, dates of birth, email addresses, genders, ip addresses, names, passwords, payment histories, payment methods, physical addresses, usernames, website activity. The breach dates from Sep 4, 2016; Have I Been Pwned loaded it on Sep 11, 2016.
What to do
- If you had a ClixSense 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.
