Analog Devices Discloses Data Breach After Unauthorized System Access
July 30, 2026 
Chipmaker Analog Devices disclosed a data breach after detecting unauthorized access to systems on June 23. The investigation is ongoing.
Semiconductor giant Analog Devices (ADI) disclosed a data breach following a cyberattack that resulted in unauthorized access to some of its systems on June 23.
Analog Devices, Inc. (ADI) is a major semiconductor company that designs and manufactures integrated circuits (ICs) used to convert, process, and manage real-world signals in electronic systems.
Unlike companies that mainly produce processors or memory chips, ADI specializes in analog and mixed-signal semiconductors, which act as the bridge between the physical world and digital systems.
Analog Devices immediately activated its incident response plan, involving cybersecurity experts and law enforcement. The company confirmed that certain files were exfiltrated, but the investigation into the scope and nature of the stolen data is still ongoing.
The US company, which generates around $12 billion in annual revenue, reported the incident to the SEC.
“On June 23, 2026, Analog Devices, Inc. (the “Company”) identified unauthorized access to certain Company systems. 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 also notified and is coordinating with law enforcement authorities. The Company’s operations were not interrupted throughout the duration of the incident.” reads the FORM 8-K report filed with SEC. “The Company’s investigation has found that certain files were exfiltrated from the affected systems. The Company’s investigation into the nature and scope of the exfiltrated information remains ongoing. To the Company’s knowledge, the data has not been publicly released or used for fraudulent purposes. The Company will continue to monitor for any indication of misuse and will take appropriate action if warranted. The Company will provide notifications to affected parties and applicable regulators as appropriate and in accordance with applicable law.”
ADI stated that the information has not been publicly disclosed or misused and that operations were not disrupted. The company does not currently expect a material business impact.
Separately, ADI is reviewing reports of an unrelated cybersecurity incident disclosed on July 26, 2026, to assess its validity, scope, and potential impact.
The report appears linked to the claims made by the cybercrime group ExfilSquad, which announced the theft of over 570,000 records from ADI. However, at this time, Analog Devices is no longer listed on ExfilSquad’s data leak site.
