Fluke Corporation had data on over 821,000 accounts exposed after the ShinyHunters group published more than 100GB of allegedly stolen data in July 2026.
What happened
According to Have I Been Pwned, in July 2026 the ShinyHunters hacking group targeted Fluke Corporation, an electronic test and measurement equipment company, in a "pay or leak" extortion campaign. When the ransom demand was not met, the group published more than 100GB of data allegedly taken from the company.
What was exposed
Reported by Have I Been Pwned, the leaked data consisted largely of corporate contact information. It included over 800,000 unique email addresses, names, phone numbers, physical addresses, employer details, job titles, and a large collection of customer support cases.
Who is affected
More than 821,000 accounts are affected, according to Have I Been Pwned. Given the nature of the exposed data — corporate contacts and support tickets — the affected individuals are likely business customers, partners, and others who had interacted with Fluke's support or sales systems.
What to do now
If you have ever provided your contact information to Fluke Corporation or submitted a support request, assume your details may be exposed. Be alert for targeted phishing emails or phone calls that use your name, employer, or job title to appear legitimate. Consider using a unique email alias for future business communications to help identify misuse of your data.
