Poland's Computer Emergency Response Team (CERT) has reported a serious cyberattack on the country's energy facilities. The attack involved the exploitation of default credentials in industrial control systems (ICS), which allowed attackers to gain unauthorized access and cause significant disruptions. This incident raises concerns about the security of critical infrastructure, particularly as it highlights the risks associated with using default login information. The targeted energy facilities are crucial for Poland's power supply, and any breach in their security can have widespread implications for both the economy and public safety. The report also suggests that this attack may be part of a broader trend of cyber threats aimed at critical infrastructure worldwide.
