Poland's computer emergency response team (CERT) has published a report detailing the recent attack by Russia-linked hackers on the country's power grid. The attack targeted communication and control systems at roughly 30 sites, including combined heat and power (CHP) plants and renewable energy dispatch centers for wind and solar facilities. The hackers gained access to industrial control systems (ICS), but primarily targeted grid safety and stability monitoring systems rather than active power generation systems.
The ransomware landscape witnessed a dramatic shift in June 2025 as the Qilin ransomware group surged to become the most active threat actor, recording 81 victims and representing a staggering 47.3% increase in activity compared to previous months.
