In the fast-evolving world of cryptocurrency, security breaches remain one of the most pressing concerns for both exchanges and users. The recent $30 million hack of Upbit, one of South Korea’s largest cryptocurrency exchanges, has reignited discussions about the need for faster and more coordinated fund-freezing mechanisms across exchanges.
Binance Freezes Only 17% of Stolen Upbit Funds
Following the theft of 44.5 billion won (approximately $30 million), Upbit requested immediate intervention from Binance and local authorities to halt the illegal movement of funds. Despite these urgent pleas, Binance was only able to freeze 80 million won (about $75,000) of the 470 million won traced to its wallets—just 17% of the stolen funds.
Binance justified the 15-hour delay in freezing assets by citing the need for additional verification. Hackers employed sophisticated laundering techniques, such as splitting amounts, using token bridges, and swapping cryptocurrencies across multiple chains. This complexity proved challenging for exchanges to act promptly.
Experts Call for Faster Freezing Mechanisms
Security experts and blockchain researchers emphasize the necessity of a global emergency hotline or a more unified system to tackle such situations. Rapid responses are essential to mitigate the fallout from large-scale hacking events. Cho Jae-woo, director of Hansung University’s Blockchain Research Institute, stated that litigation risks often deter exchanges from acting swiftly during crises.
Had Binance and other exchanges responded faster, more of the stolen funds could have been recovered before being converted—most notably from Solana to Ethereum to enhance liquidity.
Upbit’s Response and Increased Cold Storage
In response to the breach, Upbit has moved 99% of its customers’ assets into cold storage, surpassing South Korea’s legal requirement of 80%. Previously, the exchange held 98% of its assets in cold storage. This preventative measure serves to minimize the risk of future breaches but shows how exchanges are forced to make costly adjustments due to insufficient cross-platform coordination.
Enhancing Security in Crypto Trading
The Upbit hack serves as a wake-up call for crypto exchanges worldwide. Beyond technological investments, streamlined collaboration between industry stakeholders will play a pivotal role in safeguarding users and restoring trust in the cryptocurrency ecosystem. While exchanges like Binance face justified scrutiny, this incident highlights the broader need for systemic improvements.
For individuals looking to enhance their personal crypto security, hardware wallets like the Ledger Nano X are a recommended solution. These wallets store cryptocurrency offline, protecting users from online breaches.
