(MIAMI) - A French national who was serving at times as an administrator and senior moderator on one of the largest dark web criminal marketplaces pleaded guilty today to conspiracy to possess with the intent to distribute controlled substances and conspiracy to launder money. 

Gal Vallerius, aka “Oxymonster,” 36, pleaded guilty in federal court today. According to the court record, including the agreed upon factual proffer, beginning in or around November 2013 a criminal online marketplace known as Dream Market began operating on the Tor “dark web” network. Dream Market was designed to promote and facilitate the anonymous sale of illegal items. In time, the Dream Market website became one of the largest dark web criminal marketplaces. All of the items and services on Dream Market were offered for sale in exchange for Bitcoin and other peer-to-peer crypto-currencies. 

According to the agreed upon factual proffer, Vallerius first participated in the conspiracy by becoming a vendor on Dream Market. As a vendor, he sold Oxycodone and Ritalin under the moniker “Oxymonster.” Shortly thereafter, Dream Market employed the defendant who acted at times as an administrator and senior moderator. In these positions, he played a role supporting the daily illicit transactions between buyers and vendors on Dream Market, such as the trafficking in narcotics, and the laundering of illicit proceeds using virtual currencies, Dream Market’s tumblers and the dark web. Vallerius is scheduled to be sentenced by Judge Scola on Sept. 25 at 8:30 a.m.
