More than seven years have passed since Ross Ulbricht was arrested in the science fiction section of a San Francisco library and charged with running the sprawling, dark web drug bazaar known as the Silk Road. But when the Feds laid hands on Ulbricht's laptop that day, they found keys to unlock only a fraction of the bitcoins that he had amassed over the Silk Road's years of bustling black market drug trade.
Today the Justice Department finally revealed where a billion-dollar tranche of the Silk Road's treasure ended up: stolen by a mysterious hacker, and now seized by the US Treasury. The DOJ today filed a civil forfeiture complaint over 69, bitcoins—and other variants of the cryptocurrency—seized on November 3 from an unnamed person who court documents refer to only as Individual X.
According to the IRS's criminal investigation unit, Individual X successfully hacked the Silk Road sometime between May of and April of , stealing that abundance of drug money from the dark web site's bitcoin addresses before Ulbricht's downfall in October of Where did the money go? The wallet had long been visible on bitcoin's blockchain and discussed on hacker forums but had remained unmovable for anyone who didn't have the secret keys to spend it.
Though it was far from clear at the time who the coins belonged to or why they'd been moved on Tuesday, Blockchain analysis firm Elliptic at the time connected the wallet to the Silk Road: In May , the 70, coins had been moved from the Silk Road addresses to two other addresses. By April of those coins had been consolidated at a single address, where they largely sat dormant until this week.
Even then, it was unclear whether Ulbricht had simply been moving some cryptocurrency around. Later that year, though, coins moved from the address to the now defunct bitcoin exchange BTC-e. By then, Ross Ulbricht was in jail. Even if it the money was his, he wouldn't have had access to the keys necessary to move it. The government's forfeiture complaint offers an answer to that mystery: The address the coins had been moved to in belonged not to Ulbricht but to a hacker who had stolen them.
With the help of blockchain analysis firm Chainalysis, IRS investigators found 54 transactions moving 70,plus bitcoins from Silk Road addresses—transactions that Elliptic says occurred in —to the two other addresses Elliptic had flagged on Tuesday.

Bitcoin marketplaces employ a variety of methods to protect their vaults and the private keys for the bitcoins. But the companies are highly attractive targets because stolen bitcoins can be nearly impossible to recover. Unlike bank wire transfers, bitcoin transactions are irreversible. Raising the level of security around bitcoins invariably makes the virtual currency more cumbersome to access, which is why exchanges must make difficult trade-offs.
Exchanges who cater to this and put private keys on online machines put themselves at a higher risk of attack. Kirk is a veteran journalist who has reported from more than a dozen countries.

On the other hand, however, the fact that bitcoin itself is difficult to hack does not mean that it's necessarily a safe investment. There does exist the potential for security risks at various stages of the trading process. Bitcoins are held in wallets and traded through digital currency exchanges like Coinbase.
Developers are always improving wallet security, but there are also those looking to access other peoples' wallets illegally to swipe their tokens and coins. In the transaction process, two-factor identification is commonly used as a security measure. Of course, having the security of a transaction linked to an email address or a cell phone number means that anyone with access to those components can authenticate transactions.
If hackers can determine some of your non-cryptocurrency-related personal information, they may be able to infiltrate your transactions in that space regardless. Bitcoin users are assigned private keys, which allows access to their bitcoins. Hackers can infiltrate wallets and steal bitcoins if they know a user's private key. There have been widely publicized frauds, scams, and hacks that have plagued individual investors and even major cryptocurrency exchanges in their short history.
Part of the issue is simply that the technology and space are new. While this makes cryptocurrencies like bitcoin incredibly exciting—and potentially very profitable—investments, it also means that there are those looking to capitalize on security holes before they are corrected.

With the help of blockchain analysis firm Chainalysis, IRS investigators found 54 transactions moving 70,plus bitcoins from Silk Road addresses—transactions that Elliptic says occurred in —to the two other addresses Elliptic had flagged on Tuesday. The transactions were for round amounts of currency, and none appeared in the Silk Road's own logs as purchases or vendor withdrawals, suggesting that they were likely the work of Individual X transferring stolen loot.
The complaint doesn't explain how the Silk Road breach occurred or where investigators learned of those threats, but both may have been documented on Ulbricht's seized laptop or on the Silk Road's seized server. Individual X seems to have ignored Ulbricht's threats and held onto the coins long after Ulbricht was arrested, tried, and convicted, quietly watching them explode in value in the years since. It's far from clear how the IRS tracked down the hacker, why the investigation took more than seven years, or exactly what legal means the IRS used to persuade Individual X to turn over the money.
Elliptic cofounder Tom Robinson speculates that the transfer of bitcoin to BTC-e may have helped: BTC-e's operators were indicted in , and the business was seized, perhaps offering account information that put the IRS onto Individual-X's trail. The billion-dollar cryptocurrency seizure, Robinson argues, may be a sign of things to come.
The potential to seize figure funds provides an enormous incentive for law enforcement to invest time and money in tracking down the owners of illicit cryptocurrency stashes. Individual X, on the other hand, was a more disciplined investor.
And thanks to the person's fiscal conservatism, the US government stands to be about a billion dollars richer. Read more. Senior Writer Twitter. Featured Video. Blockchain, the key technology behind Bitcoin, is a new network that helps decentralize trade, and allows for more peer-to-peer transactions.
WIRED challenged political scientist and blockchain researcher Bettina Warburg to explain blockchain technology to 5 different people; a child, a teen, a college student, a grad student, and an expert. Wallets tend to be protected by strong passwords and in the event that a cybercriminal manages to obtain a wallet and cannot crack the password he might sell it to opportunistic hash crackers who are individuals with a large amount of GPU power," Gal told Motherboard in an online chat. In fact, hackers have been trading the wallet on various occasions.
On June 29 of last year, someone nicknamed humerh3 tried to sell the wallet on Bitcointalk, one of the most popular forums dedicated to the cryptocurrency. That listing is now gone, but another site has it on sale. There is no guarantee, however, that this wallet. So one could modify the file in a binary editor and change the public key of one of the address pairs to that of a high value BTC address. In practice, that means there's no way to know that this wallet actually holds the coins unless you crack and decrypt it.
The wallet could have been forged or modified to fool people into paying for something that is not what it's supposed to be. That's because it's likely that the wallet is protected with a long and unique password, and the wallet.
