WordPress security firm WordFence detected over 1.65 million daily brute-force attacks targeting WordPress sites over the past few weeks. Most of the attacks originated from a limited set of IP addresses, assigned to an ISP in the Ukraine. The company’s CEO is a man named Lizenko Dmitro Igorovich, and SKS-Lugan has around 16 employees. Ukrainian authorities have no power over the ISP because the city of Alchevs’k is in an area controlled by pro-Russian forces in eastern Ukraine.
