Hyperliquid's total value locked (TVL) has dropped by over $1 billion, a 35% decline, amid concerns of North Korean hacking activities. This has led to a 20% decrease in the platform's native token value and significant withdrawals, including a $70 million USDC outflow in one day. Security experts warn that North Korean hackers may be preparing for a larger attack after testing the platform, which has already resulted in losses of approximately $701,000.
