KyberSwap frontend exploit

KyberSwap became the latest victim of an exploit, causing loss of a considerable amount. The said DeFi liquidity hub is run by Kyber Network. The decentralized network (DEX) disclosed in a Twitter thread on Thursday that its team has identified an exploit on the frontend. The exploit was later neutralized, but the attack resulted in considerable losses, amounting to $256K.

According to the information available, the said sum was stolen from two whale accounts. As the team resolved the issue, there is little threat to the users. The platform assured that the issue had been resolved and users could utilize the network for their uses. The network cautioned the users, so they don’t fall prey to some untoward incident.

The announcement asked the users to exercise caution and don’t approve any requests that appear malicious. They have shared detailed instructions on a medium blog post to keep the customers safe. Thus, the users will be able to use KyberSwap safely without losing their sum.

According to the available information, the main target was whale wallets. The attacker would have taken much if the team hadn’t prevented it in time. Kyber Network team resolved the issue within two hours, thus saving a huge amount from being lost.

Losses incurred and other details

KyberSwap revealed that the problem was with Google Tab Manager. The malicious code in the GTM made it possible for the attackers to get access to the whale wallets. Thus, a total of $256K was lost, minimizing the losses considerably. What makes this exploit special is the claim that the KyberSwap team has said they have full details of the attackers.

These details include addresses associated with the hacker, while the OpenSea account related to the incident was also identified. The liquidity hub has warned other DeFi platforms because the GTM code problem might have affected them. In the Twitter thread, the platform said they are in contact with multiple exchanges. Thus, the hacker will be unable to cash out the funds and ultimately be caught.

The year 2022 proved ripe for hackers as a whooping amount of $1.9 billion has been lost to hackers. The data for 2021 shows that hackers took about $1.2 billion. The management of KyberSwap has ensured that the affected users in the recent exploit will be compensated. While it has also assured the rest of the users that their funds are safe. They have also said that there is no vulnerability issue in the smart contract.
