A Russian hacking group known as Sandworm has been linked to the deployment of new wiper malware, with reported targets including Ukraine's grain industry and power grid, as well as Poland's energy systems. The malware, referred to as DynoWiper, was used in an attempted attack on Poland's power sector. The scope and success of these attacks are not entirely clear, with some reports indicating a failed attack on Poland's energy systems and others suggesting disruption to Ukraine's power grid.
