Swedish thermal heating plant — attempted destructive OT attack

Sweden (facility not publicly identified)

What happened

Swedish authorities disclosed that a pro-Russian group attempted a destructive intrusion into the operational technology systems of a thermal plant supplying heating, intending to disrupt its operation. The attempt failed because of protections built into the facility, and no loss of heat supply occurred. Swedish officials framed the case as a shift by pro-Russian actors from distributed denial-of-service nuisance attacks toward attempted physical disruption of energy infrastructure, part of a broader wave of activity against European critical infrastructure. The facility was not publicly identified, so the marker is a country-level reference rather than a site location.
