Cyberattack disrupts Delta security and vehicle-control services across Russia

On 26 January 2026, Russian security-services provider Delta confirmed a large-scale cyberattack against its IT infrastructure that restricted availability of online services. Customers reported widespread problems with the mobile application and remote vehicle and alarm functions, while Delta activated recovery procedures, restored backups and introduced alternative support arrangements. The company subsequently reported that most services had returned to normal and later announced restoration of Delta Auto functionality. Delta said it found no evidence that customer personal data had been compromised.
