Fluke: Have I Been Pwned’s Post

Fluke Hit by ShinyHunters Extortion Campaign, Exposing 800K+ Email Addresses

Earlier this month, industrial technology firm Fluke fell victim to an extortion campaign by the ShinyHunters hacking group. The attackers leaked over 800,000 email addresses, along with corporate contact details and internal support case records.

According to analysis, 51% of the exposed emails were already publicly listed on LinkedIn, suggesting a mix of existing and newly compromised data. The breach highlights the group’s ongoing targeting of corporate networks, where stolen data is often used for further attacks or sold on underground markets.

Fluke has not publicly confirmed the full scope of the incident, but the leak underscores the persistent threat posed by ransomware and extortion groups to enterprise security. The exposed data could enable phishing campaigns, credential-stuffing attacks, or social engineering efforts against affected individuals and organizations.
