A cyber-attack has compromised the computer network of the German subsidiary of Moscow-based Russian energy company Rosneft.
German newspaper dies Welt reported the security incident on Sunday, describing it as a hacking attack. According to the newspaper, Germany’s cybersecurity watchdog BSI had confirmed the breach and offered to help Rosneft restore its systems.
BSI said that the attack occurred on Friday night or early Saturday morning. The Federal Cyber Security Authority has issued a warning to other energy companies to be on the alert for cyber-attacks.
According to a report by Stuttgarter Nachrichten, Rosneft reported the cyber-attack to the Berlin State Criminal Police Office on Saturday. The paper said a spokesperson said that the Berlin Public Prosecutor’s Office initiated proceedings and commissioned the Federal Criminal Police Office (BKA) to investigate further.
Although Rosneft’s systems have been impacted by the attack, die Welt reported that neither the company’s business nor its ability to supply energy had been disrupted.
Security sources cited by the newspaper suspected the hacking collective “Anonymous” of being behind the attack after the group declared its intention to hit Russian targets in response to Russia’s invasion of Ukraine.
Anonymous has published a statement on social media claiming responsibility for the attack.
