Summary

A large-scale Russian cyberattack targeted Poland, causing a near-miss incident that was not widely reported. The operation involved coordinated attempts to breach Polish critical infrastructure and governmental networks. Despite the scale and coordination, the attack was ultimately unsuccessful, with Polish cyber defenses thwarting the intrusion.
