DEX platform KyberSwap suffers $47 million hack

Decentralized exchange (DEX) protocol KyberSwap has fallen victim to a major hack, resulting in the loss of approximately $47 million worth of cryptocurrency assets. The attack targeted and drained liquidity pools leading to a significant decrease in total value locked (TVL).

This recent security breach is another blow to the crypto industry, following closely after the HECO chain bridge incident that saw an $86 million exploit. The hacker managed to siphon off $20 million in WETH, $4 million in ARB, and $7 million in wstETH from KyberSwap’s liquidity pools.

KyberSwap has urged its users to withdraw their funds as a precautionary measure in light of the breach. Although the security incident did not affect its aggregator, the protocol is diligently investigating the situation. The exploit is attributed to tick manipulation and double liquidity counting, ultimately resulting in a flash loan attack. The hacker executed swaps and manipulated prices and ticks of targeted liquidity pools, leading to the draining of the pools.

The stolen funds, including assets like wrapped Ether (wETH), Arbitrum (ARB), and wrapped Lido-staked Ether (wstETH), are spread across platforms such as Ethereum, Arbitrum, Optimism, Polygon, and Base. Subsequently, KyberSwap’s TVL plummeted to $13.61 million from over $83 million before the exploit. Additionally, the Kyber Network Crystal (KNC) token experienced a 3.1% decline, trading at approximately $0.722 at the time of writing.

KyberSwap exploited – what happened?

KyberSwap alerted its users to the exploit early Thursday, advising that customers withdraw their funds as a precaution. The exploit was the result of tick manipulation and double liquidity counting, leading to a flash loan attack that resulted in the draining of the liquidity pools.
