According to the news from Deep Tide TechFlow, on April 15, according to PeckShield monitoring, the perpetual contract DEX KiloEx was hacked today, with a total loss of approximately US$7.5 million, including US$3.3 million on the Base chain, US$3.1 million on the opBNB chain and US$1 million on the BSC chain. PeckShield analysis shows that the attacker exploited the price oracle vulnerability to make a profit by setting the ETH/USD price to 100 when creating a new position, and then immediately closing the position at an inflated 10,000 price. The agreement has been suspended at present, and the stolen funds are being transferred across chains.
