All about the Kokomo exit scam

On 26 March, Twitter account CertiK Alert notified the community that Kokomo Finance had perpetrated an exit scam. This update was a follow-up to the initial post by CertiK, which highlighted a price slippage in the protocol. The alleged exit scam is said to have resulted in approximately $4 million in losses.

Kokomo Finance, a platform launched on the Optimism network on 25 March, offered users the ability to trade, borrow, and lend various digital assets such as Wrapped Bitcoin [wBTC], Ether [ETH], Tether [USDT], USD Coin [USDC], and Dai [DAI]. However, just a day later, on March 26, Kokomo developers executed an attack on the contract cBTC from the main KOKO address, which was the native token of Kokomo. 

They adjusted the reward speed, paused the borrow feature, and created a malicious contract to interact with the rest of the protocol, as reported by CertiK. A different developer address was then utilized to approve a transfer of over 7,000 Sonne Wrapped Bitcoin. These tokens were then utilized to swap all liquidity supplied by users into Kokomo.
