The FBI has accused a Russian hacker of stealing private information and shut down its platform, Deer.io, which transferred funds through encrypted assets. According to a statement from the US Department of Justice (DoJ), the FBI closed the Deer platform on March 24. The U.S. Department of Justice states that "its suspected administrator, allegedly a Russian hacker Kirill Victorovich Firsov, was arrested and charged with a crime of attacking a U.S. company to obtain customer personal information." On March 7, the FBI detained at JFK Airport in New York Firsov. Firsov allegedly runs Deer.io, a platform launched in 2013, touting various hijacked data. It is reported that Deer.io is a Bitcoin exchange platform that provides dark web services. The platform has 24,000 online vendors and sales of more than $ 17 million. It is unclear whether the platform was still in operation between the arrest of Firsov on March 7 and March 24 when the U.S. Department of Justice issued a shutdown statement.
