Police have arrested someone believed to be a key member of the DDoS-for-bitcoin cyber-extortion gang
Police believe they have nabbed a key figure behind a series of online extortion attacks that have taken place around the world over the last 18 months.
Operation Pleiades, a joint operation by police forces from around the world, led to the arrest of a "main target" and the detention of another suspect, Europol said Tuesday.
The denial-of-service attacks on webservers and the like made by group going by the name DD4BC (Distributed DoS for Bitcoin), are followed by an email threatening that the attack will be stepped up unless a payment is made in bitcoin.
