Gox hack: Alexander Vinnik. By the end of , the US authorities had sufficient evidence to issue a warrant for the arrest of Alexander Vinnik. However, he was living in Russia at the time, so investigators waited until he left the country for a vacation in Greece. He was apprehended in July and has been held in custody in Greece ever since. Both Russia and the US have sought to extradite him. The latest news report stated that the Greek government had approved his extradition to Russia.
While all this sounds like the plot of a movie, it serves to illustrate the degree to which the world of crypto is unregulated. It only took one vigilante using his own blockchain forensics, and years of dedicated focus, to bring down an international cybercriminal.
Jonathan Levin was also one of the investigators of Mt. Levin went on to start Chainalysis , a blockchain forensics company, which provides software that can now undertake the kind of extensive blockchain analysis that Nilsson did by himself.
These companies are used by law enforcement agencies, but also by cryptocurrency businesses who see advantages in using blockchain forensics to screen customers. Criminals are now finding other ways of obscuring their movements on the blockchain. Mixer services jumble together coins in an attempt to confuse the trail of individual transactions.
Increasingly, criminals, such as those behind the WannaCry ransomware attack, are also using privacy coins such as Monero to increase their chances of remaining hidden. WannaCry emerged in It was a global ransomware attack that exploited weaknesses in Microsoft Windows to encrypt all of the data in a users computer. Once the data was encrypted, the program demanded payment in Bitcoin to decrypt the data.
Microsoft quickly released patches, but by that time more than , computers had been affected across countries. It hit hard. The architects remain unidentified. However, in August , various sources reported movements of Bitcoins from the addresses associated with the attackers.
They used Swiss company ShapeShift to convert the coins into Monero , meaning they will now likely never be found given the tight privacy around the use of Monero. ShapeShift has since taken steps to blacklist those addresses. The WannaCry case shows that blockchain forensics, like any branch of forensics, is not infallible. However, like blockchain itself, blockchain forensics is still in its infancy.
Of course, criminals will always find ever more creative ways to use cryptocurrencies for nefarious purposes. Hopefully, there will always be someone like Kim Nilsson, or companies like Chainalysis or BIG using blockchain forensics to seek them out.
