Holding Slovenske Elektrarne (HSE), a Slovenian power generation company, fell victim to a ransomware attack on Nov. 22 that compromised its systems but didnt disrupt
power production
.
The company regained control and was able to contain the attack on Nov. 24.
The National Office for Cyber Incidents at Si-CERT and the Ljubljana Police Administration were notified of the attack. The power company also worked with third-party experts to mitigate the effects of the attack and prevent the spread of the malware to other critical infrastructure systems in Slovenia.

the situation is under control
