Major Cyberattack Cripples Russia’s Alarm and Vehicle Security Provider Delta

#### Executive summary: Delta, a Russian provider of home, business, and vehicle alarm/security systems, experienced a large-scale external cyberattack that disrupted online services and communications, causing alarm malfunctions and vehicle access/control issues for many customers; the company reports no confirmed customer data compromise, but an attacker-linked Telegram channel published an unverified archive claiming stolen data. Recovery is ongoing with specialist support, the attack method and perpetrators remain unclear (ranging from DDoS to potentially destructive malware), and customer safety and service availability concerns persist.
