Hacker inserted malicious code into KyberSwap’s frontend
According to Kyber Network, its team “identified a malicious code in our Google Tag Manager (GTM)which inserted a false approval, allowing a hacker to transfer users’ funds to his address.”
Kyber continued that the threat was “neutralized” within two hours, assuring its users that it is now “safe to use all KyberSwap functions.”
KyberSwap is a multi-chain decentralized exchange (DEX) that allows users to swap tokens between different blockchains. Kyber revealed that the hack only affected the DEX’s user interface.
The Kyber team has assured the affected wallets that they will be compensated.

Meanwhile, the team has offered the hacker 15% of the funds if he chooses to return it. According to the Kyber team, there is no way for the hacker to cash out the funds through centralized exchanges that he wouldn’t be revealing himself.
7/ We strongly urge all #DeFi projects to conduct a thorough check on your frontend code & associated Google Tag Manager (GTM) scripts as the attacker may have targeted multiple sites. Let's work together as one #DeFi community to defend against these malicious attacks
