Severity: medium · Patch status: no-fix-needed · Since 2026-07-15
In July 2026, electronic test and measurement equipment company Fluke was targeted in a ShinyHunters "pay or leak" extortion campaign. The group subsequently published more than 100GB of data allegedly taken from the company. The corpus contained largely corporate contact information, including over 800k unique email addresses, names, phone numbers and physical addresses. A large collection of support cases was also present. Exposed data: email addresses, employers, job titles, names, physical addresses, support tickets. The breach dates from Jul 1, 2026; Have I Been Pwned loaded it on Jul 15, 2026.
What to do
- If you had a Fluke 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.
