Analog Devices, Inc. and Microsoft: Semiconductor Firm Analog Devices Discloses Data Breach

Analog Devices Discloses Data Breach Amid Emerging Extortion Threat

Analog Devices, Inc. (ADI), a Massachusetts-based semiconductor manufacturer with $12 billion in annual revenue and 24,000 employees, has reported a data breach following unauthorized access to its systems on June 23, 2026. The company, which designs chips for industrial, automotive, and communications sectors, detected the intrusion and launched an investigation with external cybersecurity experts.

While Analog Devices confirmed that hackers exfiltrated certain files, the company has not disclosed the nature of the compromised data. No operational disruptions were reported, and there is no evidence the stolen files have been leaked or misused. The incident is not expected to materially impact the company’s financial or operational standing.

Separately, on July 26, 2026, Analog Devices acknowledged public reports of a second, unrelated cybersecurity incident likely tied to the extortion group ExfilSquad. The group, known for data theft rather than ransomware, previously claimed to have stolen 570,000 records from the company. However, Analog Devices’ name no longer appears on ExfilSquad’s leak site, and security researchers, including SOCRadar, have questioned the validity of some of the group’s claims. ExfilSquad’s victim list has included high-profile targets such as Microsoft, Atlanta, Houston, and the UK Department of Education.

Analog Devices is currently assessing the scope and potential impact of the second incident. Further details remain pending as the investigation continues.
