South Korean Police Recover Bitcoin Linked to 2019 Upbit Hack
South Korean authorities have made a significant breakthrough by recovering 4.8 Bitcoin (BTC) connected to the infamous 2019 hack of the Upbit exchange. North Korean hackers executed this attack, stealing 342,000 Ethereum (ETH), worth $41.4 million at the time. Today, the stolen Ethereum exceeds $1 billion in value, underscoring the immense scale of the cyberattack.
The Investigation Unfolds
The National Police Agency of South Korea has confirmed the involvement of North Korean hacker groups Lazarus and Andariel in the 2019 Upbit hack. These groups are well-known for their cybercriminal activities, having stolen more than $3 billion in cryptocurrency from 2017 to 2023. This marks the first official confirmation by South Korean police linking North Korean operatives to a major cryptocurrency exchange hack.
Investigators reported that criminals laundered and converted 57% of the stolen ETH into Bitcoin. They moved the illicit funds through three North Korea-linked exchanges and 51 global platforms. Years of meticulous blockchain activity tracing and analysis of North Korean IP addresses led to a breakthrough, revealing distinctive patterns, including unique North Korean language usage. The US Federal Bureau of Investigation (FBI) supported the investigation, providing crucial expertise that significantly advanced the case.
Subsequently, the recovered Bitcoin, traced back to a Swiss exchange, has since been returned to Upbit. This marked a significant development, providing a partial closure to the saga of one of the most significant hacks in crypto history and reinforcing the importance of international collaboration in combating cybercrime.
Upbit Under Scrutiny
Amidst these developments, Upbit is facing scrutiny from South Koreaโs Financial Intelligence Unit (FIU) over potential KYC-related violations. The FIU has indicated that the exchange could be implicated in up to 600,000 compliance breaches. At the same time, the Financial Services Commission (FSC) of South Korea has raised concerns regarding Upbitโs market dominance, particularly since the exchange holds nearly 20% of the 22 trillion won deposited in K Bank, which, in turn, poses potential risks to the financial system.
Nevertheless, Upbit remains the largest South Korean crypto trading platform, with a trading volume of around $6 billion, as per data from CoinMarketCap. Significantly, this underscores its continued prominence despite these regulatory challenges and highlights its resilience in maintaining a leading position in the market.
This case not only underscores the ongoing risks posed by cybercriminals in the blockchain space but also highlights the importance of robust security measures and international cooperation in tackling these threats.
