The DDoS extortion criminal group, DD4BC, has been hunted ever since the group’s formation in July 2014 by their victims and law enforcement.

One of their first victims, Bitalo Bitcoin Exchange, issued a 100 bitcoin bounty in November 2014 for information on the full and proven identity of the perpetrators. Additionally, an international cooperation of law enforcement has been tracking the group for over a year and a half. DD4BC’s luck finally ran out. On Jan. 12, Europol announced that one person has been arrested and another detained as part of Operation Pleiades, a cooperative investigation that included law enforcement agencies from Austria, Bosnia and Herzegovina, Germany, the UK and Europol.
