Advantest confirms stolen personal data after February 2026 ransomware attack
The company says exposed records may include identity and financial details, and affected people have until January 4, 2027 to activate monitoring.
Advantest has confirmed that a February 2026 ransomware intrusion resulted in stolen personal data, turning an earlier uncertain incident into a confirmed breach with identity-theft implications for affected people. The October 6, 2026 notification says an unauthorized party accessed its systems and pulled data from its servers, including personally identifiable information. The exposed material may include contact details, birth dates, Social Security numbers, national ID numbers, driver’s licenses, passport numbers, medical information, financial information, and other ID numbers. Advantest says it does not know whether the data has been leaked or misused, and it is offering 18 months of Kroll identity-theft, credit, and web monitoring that recipients must activate by January 4, 2027.
Why it matters
For people whose data was in the incident, this turns an uncertain ransomware case into a confirmed breach with possible identity-theft risk. The company says it has no information that the data was leaked or misused, but recipients now have a limited window to enroll in monitoring and watch for misuse of the exposed details.
