Cyberattack Leaves Finnish Apartment Dwellers in the Cold

Lappeenranta, Finland

A Finnish company confirmed a distributed denial-of-service attack that left at least two blocks of apartments without power for multiple days.

Valtia, a facilities services company, confirmed two apartment buildings in Lappeenranta, Finland, lost heat and hot water from Nov. 3 through Nov. 4, according to The Security Ledger. The attack hit the the building automation systems with fake internet traffic, blocking remote access and causing restarts.

Valtia resolved the issue by switching systems to manual and moving them behind firewalls, according to a report in The Hacker News.
