North Korean Hackers Successfully Steal $1 Billion in Cryptocurrency in 2023
Article Highlights
North Korean hacking groups like Lazarus have stolen a record-breaking $1.7 billion using advanced tactics.
Their primary targets are decentralized finance platforms, but exchanges and wallets are also at risk.
With sanctions on platforms like Tornado Cash, these groups are seeking alternative laundering techniques like Sinbad.
In a surprising revelation, experts have disclosed that despite a significant decrease in the overall funds stolen from cryptocurrency platforms by over 50% in 2023, the threat of hacking remains high with a noticeable increase in incidents. Particularly concerning is the rise in cyber heists carried out by North Korea-linked groups, such as the notorious Lazarus group, who are using increasingly sophisticated methods to steal large amounts of crypto assets.
These nefarious entities associated with the Democratic People’s Republic of Korea (DPRK) acquired an astonishing $1.7 billion illegally in 2022, marking a record high in the history of cryptocurrency theft. The number of such breaches reached 20 last year, the highest ever recorded, highlighting a persistent and evolving threat.

A comprehensive analysis by Chainalysis provides insight into the breakdown of these thefts. North Korea-linked hackers primarily target DeFi (Decentralized Finance) platforms, from which they stole approximately $428.8 million in 2023. Centralized services, exchanges, and wallet providers also fell victim, with losses exceeding $150 million, $330.9 million, and $127.0 million, respectively.
The main tactics used by these North Korean cyber criminals involve infiltrating digital wallets by compromising private keys or seed phrases, which strikes at the heart of digital asset security. Once breached, the stolen assets are transferred to DPRK-controlled wallet addresses, often converted to USDT or Tron, and then laundered into hard currency through high-volume OTC brokers.

Adapting to the Crackdown
Under intense pressure from international law enforcement and sanctions targeting their preferred currency mixing services like Tornado Cash and ChipMixer, these hackers have shifted their focus to alternative mixers such as the BTC service Sinbad. Despite subsequent sanctions on Sinbad, their relentless pursuit of new and elusive laundering techniques remains unquenched.
Looking Ahead: Crypto Security in 2024
Over the past two years, North Korean hackers and their counterparts have seized billions in crypto assets, emphasizing the urgent need for continuous advancements in cybersecurity. In response to this call, the crypto community has strengthened its defenses, implementing enhanced security measures and improving tracking and recovery efforts for stolen funds.
As we enter 2024, there is cautious optimism that these efforts will mitigate the impact of the world’s most formidable crypto thieves, ensuring a safer environment for digital asset holders.
