The previous yr noticed a panoramic rise within the worth of cryptocurrencies like Bitcoin and Ethereum, with Bitcoin gaining 60 % in worth in 2021 and Ethereum spiking 80 %. So maybe it is no shock that the relentless North Korean hackers who feed off that booming crypto financial system had an excellent yr as nicely.
North Korean hackers stole a complete of $395 million price of crypto cash final yr throughout seven intrusions into cryptocurrency exchanges and funding companies, based on blockchain evaluation agency Chainalysis. The nine-figure sum represents a virtually $100 million enhance over the earlier yr’s thefts by North Korean hacker teams, and it brings their complete haul over the previous 5 years to $1.5 billion in cryptocurrency alone—not together with the uncounted a whole lot of tens of millions extra the nation has stolen from the standard monetary system. That hoard of stolen cryptocurrency now contributes considerably to the coffers of Kim Jong-un’s totalitarian regime because it seeks to fund itself—and its weapons packages—regardless of the nation’s closely sanctioned, remoted, and ailing financial system.
“They have been very profitable,” says Erin Plante, a senior director of investigations at Chainalysis, whose report calls 2021 a “banner yr” for North Korean cryptocurrency thefts. The findings present that North Korea’s international, serial robberies have accelerated even within the midst of an tried regulation enforcement crackdown; the US Justice Division, as an illustration, indicted three North Koreans in absentia in February of final yr, accusing them of stealing at the least $121 million from cryptocurrency companies together with a slew of different monetary crimes. Prices had been additionally introduced in opposition to a Canadian man who had allegedly helped to launder the funds. However these efforts have not stopped the hemorrhaging of crypto wealth. “We had been excited to see actions in opposition to North Korea from regulation enforcement businesses,” Plante says, “but the risk persists and is rising.”

The Chainalysis numbers, primarily based on alternate charges on the time the cash was stolen, do not merely level to an appreciation of cryptocurrency’s worth. The expansion in stolen funds additionally tracks with the variety of thefts final yr; the seven breaches Chainalysis tracked in 2021 quantity to 3 greater than in 2020, although fewer than the ten profitable assaults that North Korean hackers carried out in 2018, once they stole a document $522 million.
For the primary time since Chainalysis started monitoring North Korean cryptocurrency thefts, Bitcoin now not represents wherever close to nearly all of the nation’s take, accounting for under round 20 % of the stolen funds. Totally 58 % of the teams’ cryptocurrency positive aspects got here as a substitute within the type of stolen ether, the Ethereum community’s foreign money unit. One other 11 %, round $40 million, got here from stolen ERC-20 tokens, a type of crypto asset used to create good contracts on the Ethereum blockchain.
Chainalysis’ Plante attributes that elevated give attention to Ethereum-based cryptocurrencies—$272 million in complete thefts final yr versus $161 million in 2020—to the skyrocketing value of property within the Ethereum financial system, mixed with the nascent firms that progress has fostered. “A few of these exchanges and buying and selling platforms are simply newer and probably extra susceptible to all these intrusions,” she says. “They’re buying and selling closely in ether and ERC-20 tokens, they usually’re simply simpler targets.”
Whereas Chainalysis declined to establish many of the victims of the hacker thefts it tracked final yr, its report does blame North Korean hackers for the theft of round $97 million in crypto property from the Japanese alternate Liquid.com in August, together with $45 million in Ethereum tokens. (Liquid.com did not reply to WIRED’s request for touch upon its August hacker breach.) Chainalysis says it linked all seven 2021 cryptocurrency hacks to North Korea primarily based on malware samples, hacking infrastructure, and following the stolen cash into clusters of blockchain addresses it has recognized as managed by the North Korean hackers.
Chainalysis says the thefts had been all carried out by Lazarus, a unfastened grouping of hackers all extensively believed to be working within the service of the North Korean authorities. However different hacker-tracking companies have identified that Lazarus contains many distinct teams. Safety agency Mandiant nonetheless echoes Chainalysis’ findings that stealing cryptocurrency has develop into a precedence for nearly the entire North Korean teams it tracks, along with no matter different missions they could pursue.

Final yr, as an illustration, two North Korean teams Mandiant calls TEMP.Hermit and Kimsuky each appeared tasked with concentrating on biomedical and pharmaceutical organizations, more likely to steal info associated to COVID-19, says Fred Plan, a senior analyst at Mandiant. But each teams continued to focus on cryptocurrency holders all year long. “That consistency of financially motivated operations and campaigns continues to be the undercurrent of all these different actions that they needed to do up to now yr,” says Plan.
Even the group Mandiant calls APT38—which has beforehand centered on extra conventional monetary intrusions, such because the theft of $110 million from the Mexican monetary agency Bancomext and $81 million from Bangladesh’s Central Financial institution—now seems to have turned its sights on cryptocurrency targets. “Virtually the entire North Korean teams we monitor have a finger within the pie of cryptocurrency ultimately,” Plan says.
One motive the hackers have centered on cryptocurrency over different types of monetary crime is little doubt the relative ease of laundering digital money. After APT38’s Bangladeshi financial institution heist, as an illustration, the North Koreans needed to enlist Chinese language cash launderers to gamble its tens of tens of millions at a on line casino in Manila to forestall investigators from monitoring the stolen funds. Against this, Chainalysis discovered that the teams have loads of choices to launder its stolen cryptocurrency. They’ve cashed out their positive aspects by way of exchanges—largely exploiting ones primarily based in Asia and buying and selling their cryptocurrency for Chinese language renminbi—which have less-than-stringent compliance with “know-your-customer” rules. The teams have typically used “mixing” providers to obscure the cash’s origins. And in lots of instances they’ve used decentralized exchanges designed to straight join cryptocurrency merchants with no middleman, typically with little in the way in which of anti-money-laundering guidelines.
Chainalysis discovered that the North Koreans have been remarkably affected person in cashing out their stolen crypto, typically holding onto the funds for years earlier than starting the laundering course of. The hackers, actually, seem to nonetheless be holding on to $170 million in unlaundered cryptocurrency from earlier years’ thefts, which they will undoubtedly money out over time.
All of these a whole lot of tens of millions, says Mandiant’s Fred Plan, will find yourself within the accounts of a extremely militarized rogue nation that has spent years underneath extreme sanctions. “The North Korean regime has found out they haven’t any different choices. They haven’t any different possible way of partaking with the world or with the financial system. However they do have this gorgeous superior cyber functionality,” says Plan. “They usually’re in a position to leverage it to convey cash into the nation.”
Till the cryptocurrency trade figures out methods to safe itself in opposition to these hackers—or to forestall their cash from being laundered and transformed into clear payments—the Kim regime’s illicit, ethereal income stream will solely proceed to develop.
