A cyberattack on Delta, a Russian provider of alarm and security systems for homes, businesses, and vehicles, has disrupted operations and triggered widespread service outages, leaving many customers unable to access critical security functions.
Delta, which serves tens of thousands of users across Russia, confirmed the Delta cyberattack on Monday, stating that it faced a major external assault on its IT infrastructure. The disruption due to cyberattack on Delta has affected both online services and customer communication channels, raising concerns about the resilience of connected security platforms.
Cyberattack on Delta Security Systems Causes Major Outage
In an official statement, the company emphasized its position in the market and its ongoing investments in cybersecurity. Delta said:
“On January 26, DELTA experienced a large-scale external attack on its IT infrastructure aimed at disrupting the company’s services.”
The company added that some services were temporarily unavailable, but insisted there were no immediate signs of customer data exposure.
“At this time, no signs of a compromise of customer personal data have been detected.”


Delta also apologized to customers and said restoration efforts were underway with the help of specialized experts.
Delta Struggles to Restore Services After Cyberattack
Delta marketing director Valery Ushkov provided additional details in a video address, acknowledging the large scale of the incident. He said:
“Our architecture was unable to withstand a well-coordinated attack coming from outside the country.”
Ushkov noted that recovery was taking longer than expected because the company was still facing the risk of follow-up attacks while attempting to restore backups.
As of Tuesday, Delta’s website and phone lines remained offline. With traditional communication channels down, the company has been forced to issue updates through its official page on VKontakte, Russia’s largest social media platform.
Customers Report Alarm Failures and Vehicle Access Issues
The Delta cyberattack disruption has had direct consequences for customers relying on the company’s systems for everyday safety and mobility.
Russian-language Telegram outlet Baza reported that users began complaining shortly after the incidentof cyberattack on Delta that car alarm systems could not be turned off, and in some cases, vehicles could not be unlocked.
Newspaper Kommersant also reported ongoing failures despite Delta’s assurances that most services were operating normally. Users described serious malfunctions, including remote vehicle start features failing, doors locking unexpectedly, and engines shutting down while in motion.
In addition to vehicle-related issues, customers reported that alarm systems in homes and commercial buildings switched into emergency mode and could not be deactivated. Recorded Future News said it could not independently verify these claims.
Data Leak Claims Surface After Delta Cyberattack
Although Delta maintains that no customer data was compromised, uncertainty remains.
An unidentified Telegram channel claiming to be operated by the attackers published an archive it alleges contains stolen information from Delta systems. However, the authenticity of the material and the identity of the hackers have not been independently verified.
The cyberattack on Delta has increased anxiety among customers, particularly because Delta’s mobile app, launched in 2020, is widely used for tracking vehicles and managing alarm functions. According to Auto.ru, the app is compatible with most cars and can store payment data, making some users wary of potential financial exposure if internal systems were breached.
Broader Pattern of IT Disruptions in Russia
The Delta security systems cyberattack occurred on the same day as a separate large-scale outage affected booking and check-in systems used by Russian airlines and airports. Airlines reported temporary disruptions to ticket sales, refunds, and rebooking after problems were detected in aviation IT platforms.
While the two incidents have not been officially linked, the timing highlights growing instability in critical digital infrastructure.
No known hacking group has claimed responsibility for the cyberattack on Delta so far. It also remains unclear whether the incident was a relatively limited distributed denial-of-service (DDoS) attack or something more severe, such as ransomware or destructive malware.
For now, Delta says the situation is manageable and expects services to return soon, but customer concerns continue as outages persist and unverified leak claims circulate.
