Analog Devices discloses data breach after hackers accessed company systems

Analog Devices, Inc., a Massachusetts-based semiconductor manufacturer, has disclosed a data breach after unauthorized parties accessed company systems and removed certain files. The company identified the intrusion on June 23 and moved quickly to contain it.

In a filing with the U.S. Securities and Exchange Commission, Analog Devices stated, "On June 23, 2026, Analog Devices, Inc. identified unauthorized access to certain Company systems." The company added, "Following detection of the unauthorized access, the Company immediately activated its incident response protocols and engaged external cybersecurity experts to assist with containment and investigation activities."

The company has not disclosed what type of data was taken. It said it has no indication that the stolen files have surfaced online or been used fraudulently, though it will continue monitoring for signs of misuse. Law enforcement has been notified, and Analog Devices said it will inform affected parties and regulators about the compromised information.

Analog Devices makes analog, mixed-signal, power management and digital signal processing chips that serve industrial automation, automotive systems, communications networks, healthcare equipment, aerospace and data center customers. The company employs about 24,500 people worldwide and reported more than $11 billion in revenue in 2025.

The company said its operations continued without interruption during the breach and does not expect the incident to materially affect its business, operations or financial condition.

Separately, Analog Devices is examining a second cybersecurity matter that came to light in public reports on July 26. The company has not confirmed whether this matter is connected to the breach described in its SEC filing. The July 26 reports may relate to claims made by a data-extortion group calling itself ExfilSquad, which had listed Analog Devices on its leak site as a victim, claiming to have exfiltrated company data. Analog Devices no longer appears on that site, though the reason for its removal has not been established; extortion groups sometimes delist victims once ransom negotiations begin.

No ransomware or data-extortion group other than ExfilSquad has claimed an attack on Analog Devices.
