Kalmar, a municipality in Sweden, has been hit by a significant IT attack attributed to the Russian-linked hacker group Akira.

The cyber assault led to a shutdown of the municipality's network and affected various services, including education and healthcare.

Critical systems like alarms and infrastructure remain operational, though non-essential services faced disruptions.

The municipality's response included entering a heightened state of readiness and convening an emergency meeting to manage the situation.

While the full extent of the intrusion is still being assessed, officials have not reported any data breaches or ransom demands thus far.

The attack on Kalmar follows a recent pattern of cyberattacks by Akira on Swedish entities, raising concerns over the country's digital security preparedness.
