Feds Seize $1 Billion in Stolen Silk Road Bitcoins

Much more than 7 many years have handed considering the fact that Ross Ulbricht was arrested in the science fiction segment of a San Francisco library and charged with jogging the sprawling, dim internet drug bazaar acknowledged as the Silk Road. But when the Feds laid arms on Ulbricht’s notebook that working day, they located keys to unlock only a portion of the bitcoins that he experienced amassed above the Silk Road’s decades of bustling black current market drug trade. These days the Justice Office ultimately unveiled where a billion-dollar tranche of the Silk Road’s treasure finished up: stolen by a mysterious hacker, and now seized by the US Treasury.

The DOJ today filed a civil forfeiture criticism around 69,370 bitcoins—and other variants of the cryptocurrency—seized on November 3 from an unnamed person who court files refer to only as Unique X. According to the IRS’s criminal investigation device, Individual X correctly hacked the Silk Street someday involving May of 2012 and April of 2013, stealing that abundance of drug cash from the dark world-wide-web site’s bitcoin addresses right before Ulbricht’s downfall in October of 2013. The IRS states it has ultimately tracked down the hacker who stole the Silk Road’s almost 70,000 bitcoins—now worth a lot more than $1 billion—and permitted law enforcement to get command of those money.

“The profitable prosecution of Silk Road’s founder in 2015 still left open a billion-greenback query. In which did the dollars go?” wrote US attorney David Anderson in a statement announcing the seizure. “Today’s forfeiture complaint answers this open up question at the very least in component. $1 billion of these criminal proceeds are now in the United States’ possession.”

Cryptocurrency analysts initial spotted the movement of the $1 billion selection of cash on the night time of November 3. The wallet experienced very long been noticeable on bitcoin’s blockchain and reviewed on hacker community forums but experienced remained unmovable for any person who didn’t have the solution keys to invest it. While it was significantly from clear at the time who the cash belonged to or why they’d been moved on Tuesday, Blockchain evaluation company Elliptic at the time linked the wallet to the Silk Highway: In Might 2012, the 70,000 coins experienced been moved from the Silk Street addresses to two other addresses.

By April of 2013 people cash had been consolidated at a solitary address, where by they mostly sat dormant until this week. Even then, it was unclear no matter whether Ulbricht had simply been shifting some cryptocurrency all around. Later on that calendar year, nevertheless, 101 coins moved from the handle to the now defunct bitcoin exchange BTC-e. By then, Ross Ulbricht was in jail. Even if it the money was his, he would not have experienced access to the keys important to shift it.

The government’s forfeiture complaint provides an solution to that mystery: The handle the cash experienced been moved to in 2013 belonged not to Ulbricht but to a hacker who experienced stolen them. With the assistance of blockchain evaluation agency Chainalysis, IRS investigators uncovered 54 transactions shifting 70,000-moreover bitcoins from Silk Street addresses—transactions that Elliptic states happened in 2012—to the two other addresses Elliptic had flagged on Tuesday. The transactions have been for spherical amounts of forex, and none appeared in the Silk Road’s own logs as buys or vendor withdrawals, suggesting that they have been possible the perform of Unique X transferring stolen loot.

In reality, the forfeiture complaint states that it identified evidence that Ulbricht managed to establish the on line persona of the particular person who experienced someway hacked the Silk Highway and taken the funds—worth $354,000 at the time—and threatened Specific X to try out to coerce them to return the income. (The complaint would not reveal how the Silk Street breach transpired or where investigators discovered of all those threats, but both of those may have been documented on Ulbricht’s seized laptop computer or on the Silk Road’s seized server.) Individual X appears to have overlooked Ulbricht’s threats and held onto the coins very long following Ulbricht was arrested, tried out, and convicted, quietly looking at them explode in value in the a long time given that.
