- Hackers have shut down the heating system in a Ukrainian city using malware, according to researchers. The attack targeted the city's heating infrastructure, leaving residents without heat during the winter months. Cybersecurity experts believe the incident is part of a broader campaign to disrupt critical infrastructure in Ukraine.

- The malware used in the attack is known as "Industroyer2," which was previously used in a 2016 attack that caused a widespread power outage in Ukraine. The malware is designed to target industrial control systems, allowing attackers to manipulate and shut down essential services. Researchers say the hackers were able to gain access to the heating system's network and deploy the malware.

- The attack highlights the ongoing threat of cyberattacks against critical infrastructure, especially in regions like Ukraine that have been the target of such attacks in the past. Experts warn that these types of attacks can have severe consequences for the affected population and call for stronger cybersecurity measures to protect essential services from such threats.
