Carhartt data breach: 12.9M accounts exposed
Severity: medium · Patch status: no-fix-needed · Since 2026-08-25
In August 2026, clothing retailer Carhartt was the target of a ShinyHunters "pay or leak" extortion campaign. The group subsequently published data allegedly obtained from the company including 12.9M unique email addresses, names, phone numbers and physical addresses. The published corpus also contained millions of synthetic records that did not relate to real individuals and were excluded from the breach. Exposed data: email addresses, names, phone numbers, physical addresses. The breach dates from Aug 13, 2026; Have I Been Pwned loaded it on Aug 25, 2026.
What to do
- If you had a Carhartt 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.
