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.

What leaked

Postal address

Used to stage a delivery, a utility visit or a neighbour that never happened.

Social engineering →

The address every one of these scams will arrive at.

Employer & job

Who to impersonate, and who to impersonate them to.

Spear phishing →
Name

Used to make a cold approach look like a conversation already under way.

Social engineering →
Support history

Bank details
Card numbers

So there is no password to change here — the usual first move does not apply.
