2026 Analog Devices — unauthorized access; files exfiltrated (SEC 8-K)
Data compromised
Certain files exfiltrated from affected systems — nature and scope still under investigation per company; ADI stated to its knowledge data had not been publicly released or used for fraud at filing time
Technical writeup
Verified company disclosure — Analog Devices Form 8-K (Item 8.01). On June 23, 2026, Analog Devices identified unauthorized access to certain company systems, activated incident-response protocols, engaged external cybersecurity experts, and notified law enforcement. The investigation found that certain files were exfiltrated from the affected systems; analysis of the nature and scope of exfiltrated information remained ongoing at filing. ADI said operations were not interrupted and, based on information then known, did not believe the incident was reasonably likely to materially impact business, operations, or financial condition. Separately, on July 26, 2026, the company said it was assessing public reports about a disparate cybersecurity matter unrelated to the June 23 incident. No attested individual count was published with the 8-K.
