DCLeaks was a hacker group that was active in the mid-2010s and known for its involvement in a number of high-profile cyber attacks and data breaches. The group was responsible for the leak of a large number of documents from various organizations, including the Democratic National Committee (DNC) during the 2016 United States presidential election.
DCLeaks was believed to be a front for the Russian military intelligence agency known as the GRU, and it was reportedly involved in a number of cyber attacks against political organizations and individuals in the United States.
The group gained notoriety for its involvement in the hack of the DNC's email servers, which resulted in the release of a large number of sensitive documents and emails. The hack was a major factor in the controversy surrounding the 2016 election, and it led to the indictment of several individuals in connection with the attack.
DCLeaks is no longer active, and it is not clear whether the group is still in operation or if its members have been apprehended."
