Upbit, a prominent South Korean cryptocurrency exchange, has reported a significant security breach involving assets on the Solana network, with an estimated loss of $36 million. The sophisticated nature of the attack has led to speculation about the involvement of North Korea's Lazarus Group.
This incident highlights ongoing vulnerabilities within cryptocurrency exchanges, underscores the persistent threat of geopolitical cyberattacks, and has caused temporary disruptions in the Solana token markets. Upbit has pledged to fully reimburse all affected user assets.
Upbit's Response to the $36 Million Breach
Dunamu Inc.'s Upbit detected irregular withdrawals occurring on the Solana network. The exchange confirmed that 24 Solana-based tokens, including SOL and USDC, were impacted by the breach. The attack method, described as highly sophisticated, has fueled suspicions regarding the potential involvement of North Korea's Lazarus Group, a notorious hacking collective.
Ki Young Ju, CEO of CryptoQuant, commented on the incident, stating, "The attack method disclosed by Upbit is almost impossible for an ordinary hacker to execute." He further suggested that if the disclosure is accurate, "I doubt any hacker organization other than North Korea's Lazarus could achieve this." Initial market anxiety was somewhat alleviated by a reevaluation of the withdrawn crypto values, which adjusted the estimated impact. Solana tokens on Upbit experienced an unexpected price surge due to the temporary halt in arbitrage operations. In response to the breach, the exchange initiated asset freezes totaling approximately 2.3 billion KRW.
The crypto community's reaction has largely focused on the complexity of the attack. Dunamu has committed to reimbursing all affected assets, a move that is expected to bolster user confidence, particularly within South Korea's strict financial regulatory environment.
Market Volatility and Solana's Performance
This incident echoes a previous security breach experienced by Upbit six years prior, on a similar date, when an estimated $41.5 million in Ethereum was allegedly stolen, also attributed to the Lazarus Group. This recurring pattern underscores both the persistent threat posed by advanced hacking collectives and Upbit's ongoing commitment to ensuring user asset reimbursement.
According to CoinMarketCap data, Solana (SOL) has a market capitalization of $79.26 billion, with its current price standing at $141.68. Solana's 24-hour trading volume is approximately $3.53 billion, showing a recent decline. Despite a notable 12.16% increase in SOL's price over the past week, the token has experienced a 27.10% drop over the last 30 days, indicating significant market volatility.

Researchers at Coincu anticipate that this event will lead to increased scrutiny of exchange security protocols. It is expected that there will be advancements in technological safeguards to enhance user protection. Regulatory bodies may also revisit existing frameworks to address complex exploits and ensure more robust defenses within the cryptocurrency trading ecosystem.
