Cyberattack on Delta Disrupts Vehicle Alarms and Access Systems

Russian security systems provider Delta said it was hit by a cyberattack that disrupted services used in commercial facilities, private homes, and automobiles. Reports said customers experienced widespread failures in vehicle security functions, including cars that would not start, alarms that could not be turned off, and vehicles that could not be opened, while some users were told recovery might require dealer reflashing. At the same time, Delta’s website was unavailable and its phone lines were reportedly unreachable, compounding the outage.

The incident drew concern because Delta’s products are used for remote protection and access control, raising the prospect of broad operational disruption for customers. Delta confirmed the cyberattack to Russian media, but no actor had been publicly identified, and there was no confirmed evidence of a personal data leak despite customer fears that account or vehicle-related information may have been exposed.
