FBI steps up search for members of cybercrime group 2 years after announcing it had taken its systems down

The FBI has stepped up its search for members of a multimillion-dollar cybercrime group more than two years after the bureau and its European allies announced they had taken down the group’s computer systems, according to newly unsealed court documents reviewed by CNN.

A hacking tool associated with the group – whose operations were previously traced to eastern Ukraine – has stalked the internet for nearly a decade, costing victims hundreds of millions of dollars, and leading to a disruptive ransomware attack on a US school in 2017.
