A new cryptocurrency exchange named Grinex is believed to be a rebrand of Garantex, a Russian cryptocurrency exchange whose domains were seized by the U.S. authorities and an admin arrested.

According to a new report by blockchain intelligence firm TRM Labs, Grinex shows strong ties to Garantex's previous operations but has not determined if it's currently being used for illicit transactions.
