A Russian envoy has said Swedish cyberattack claims are based on “unfounded suspicions” and “highly likely” conjecture
Stockholm’s allegations that a pro-Russian hacker group attempted to disrupt a thermal power plant in Sweden last year are unfounded and lacking concrete evidence, Russia’s ambassador to the country, Sergey Belyaev, has said.
Swedish Civil Defense Minister Carl-Oskar Bohlin claimed on Wednesday that a group linked to Russian intelligence attempted to attack a district heating plant in western Sweden in the spring of 2025. Bohlin stated that Swedish security services had identified the actor behind the attack, which he said was thwarted by the plant’s built-in security systems.
“The Swedish Security Service handled the case and was able to identify the actor behind it, which has ties to Russian intelligence and security services,” Bohlin told reporters.
However, Belyaev has rejected the allegations as baseless, noting that Stockholm has not sought any consultations with the Russian side over the issue, which suggests that “there are no specific facts or evidence.”
He further stated that claims about the alleged involvement of “certain Russian hackers in such illegal activity remain at the level of the ‘highly likely’ principle, beloved by Western countries, that is, unfounded suspicions.”
Moscow has repeatedly denied Western accusations of involvement in hacking activities as warmongering and has consistently expressed willingness to cooperate on cybersecurity matters.
Kremlin spokesman Dmitry Peskov previously noted that accusing Russia of hacking is “a favorite hobby around the world,” and that blaming Moscow for everything has become a common trend in the West.
The latest Swedish allegations come amid heightened tensions between Moscow and NATO. The military bloc has cited the supposed threat of Russian aggression to justify a massive military buildup and developing offensive cyber capabilities.
In February, the EU’s tech chief Henna Virkkunen also said it was “not enough” to have defensive measures and that the bloc needs also to have “offensive capacity.”
The number of DDoS attacks on Russian companies exceeded 186,000 in 2025, marking a 2.7‑fold increase from the previous year, according to the RED Security cybersecurity firm. In 2026, the upward trend has continued, with weekly attacks on state resources surging from an average of 350 to 949 in the spring, according to the Russian authorities.
