North Korean Affiliates Suspected in $40M Cryptocurrency Heist, FBI Warns

The U.S. Federal Bureau of Investigation (FBI) has issued a warning about North Korean threat actors, cautioning that they may attempt to cash out stolen cryptocurrency worth more than $40 million. This alert comes amidst an ongoing investigation by the FBI into a group affiliated with North Korea, which recently moved approximately 1,580 bitcoins from several cryptocurrency heists. The funds are currently being held in six different wallets, raising concerns about the potential exploitation of digital assets for illicit activities.

Investigation findings

The FBI’s investigation has shed light on the tactics employed by this North Korean-affiliated group, dubbed TraderTraitor. It has been determined that they executed a series of cryptocurrency heists, amassing a substantial amount of stolen bitcoin. The movement of 1,580 bitcoin in the past 24 hours indicates the urgency and intent of the group to convert their ill-gotten gains into usable funds.

North Korea’s approach to cybercrime

North Korea has long been known for its unconventional approach to cyber warfare, espionage, and financial crime. This latest warning from the FBI further underscores their propensity for blurring the lines between these domains. The intersection of cyber capabilities and financial crimes enables North Korean threat actors to amass significant wealth while evading international sanctions.

Identification of TraderTraitor

TraderTraitor, in particular, has been linked to a string of attacks targeting blockchain and cryptocurrency exchanges with the goal of plundering digital assets to generate illicit revenue for the sanctions-hit nation. Notable heists include the $60 million theft of virtual currency from Alphapo, the $37 million theft from CoinsPaid, and the $100 million theft from Atomic Wallet. Moreover, the group has also been implicated in attacks targeting Sky Mavis’ Ronin Network and Harmony Horizon Bridge in the past year.

Connection to APT38 and the Lazarus Group

The cluster of activities attributed to TraderTraitor shows significant overlap with another North Korean group known as APT38 (also referred to as BlueNoroff or Stardust Chollima). APT38, in turn, is part of the larger Lazarus constellation, a collective of cyber threat actors notorious for their involvement in high-profile cyber-attacks and financial thefts.

Additional modifications

Interestingly, Google-owned Mandiant recently connected TraderTraitor to UNC4899, a hacking crew responsible for the JumpCloud breach in late June 2023. This connection suggests a complex network of affiliations and collaborations within the North Korean cyber landscape.

Scope of North Korean cryptocurrency theft

According to data compiled by blockchain intelligence firm TRM Labs, North Korean hackers have successfully stolen over $2 billion in cryptocurrencies since 2018 through a series of approximately 30 attacks. In 2023 alone, they managed to pilfer a staggering $200 million. These numbers highlight the scale and persistence of North Korea’s cryptocurrency theft campaigns, emphasizing the need for increased vigilance and stronger security measures within the crypto sphere.

FBI recommendations

In light of the ongoing threats posed by North Korean affiliates, the FBI advises private sector entities to closely examine blockchain data associated with the identified addresses. They encourage caution when engaging in any transactions directly with, or derived from, these addresses. Staying informed and implementing robust security measures is crucial to safeguard against any potential fraudulent activities.

The FBI’s warning about North Korean threat actors attempting to cash out stolen cryptocurrency worth more than $40 million underscores the persistent and evolving nature of cybercrime. The ongoing investigation into TraderTraitor reveals their efforts to exploit the vast potential of cryptocurrencies for illicit gains. As North Korea continues to blur the lines between cyber warfare, espionage, and financial crime, it is crucial for individuals, organizations, and governments to maintain constant vigilance and implement stringent security measures to guard against these sophisticated threat actors.
