New York-based Verizon Communications Inc. has been hit with a suit claiming one of its technicians helped hackers pull off a $67,000 cryptocurrency fraud against a New Jersey man.

Thieves stole the money from a Coinbase account, an Ethereum wallet and a Ripple wallet belonging to Dennis DePalma of West Caldwell, New Jersey, after a worker at a Verizon store allegedly gave an unknown party access to DePalma’s phone, according to a suit filed in the U.S. District Court for the District of New Jersey.
