Borgholm is a municipality located in Kalmar län, Sweden. It provides essential public services including local healthcare, utility management through the municipal company Borgholm Energi, and digital infrastructure for administrative and communication systems.

In December 2022, a cyberattack targeting municipalities in Kalmar län affected Borgholm. The incident prompted an internet traffic shutdown for Borgholm and neighboring Mörbylånga to contain the breach, resulting in disrupted email systems and the Mörbylånga website. Data exfiltration occurred, though initial details were unclear. Critical services, including healthcare, were shifted to manual operations, while utilities and alarm systems remained functional. Borgholm Energi experienced communication outages, limiting digital and phone accessibility as a precaution. IT teams focused on securing infrastructure and patching vulnerabilities, with recovery expected to take multiple days. This event illustrates Borgholm's reliance on digital systems for public service delivery and its capacity for incident response to maintain essential operations during cyber disruptions.
