“On March 1, a cryptocurrency address that security researchers had already mapped to BlackCat received a single transaction worth approximately $22 million.”
Change Healthcare will neither confirm nor deny paying, and the blockchain answers for it. The affiliate who broke in says BlackCat kept his cut and he still has the data, including from Medicare. BlackCat then shut down, claimed it got “screwed by the feds,” and sold its source code. Change paid $22 million to keep the data private, and it is still sitting with an angry affiliate.
