What to do

If you are an ADI customer, supplier, or employee, watch for an official notification letter or email from Analog Devices, since the company says it will notify affected parties and regulators once its investigation is further along.

Reported details

Analog Devices disclosed in a Form 8-K filed with the SEC that it detected unauthorized access to certain company systems on June 23, 2026. It activated incident response, brought in outside cybersecurity firms, and notified law enforcement. Investigators confirmed files were exfiltrated but the scope and content of that data are still being determined, and ADI says the data has not been publicly released or used fraudulently so far.

An extortion group calling itself ExfilSquad separately listed Analog Devices on its leak site around July 26, 2026, claiming roughly 570,000 stolen customer records with personal and address data. ADI has not attributed the June intrusion to this group, the claim is unverified, and the listing has since been removed from the group's site.
