PANews reported on April 15 that according to Cyvers monitoring, multiple suspicious transactions involving the perpetual contract platform KiloEx were detected, and these transactions spanned multiple chains. An address injected with Tornado Cash executed a series of transactions on the BNB, Base, and Taiko chains that exploited vulnerabilities, with a cumulative amount of approximately $7 million. The root cause may be the existence of a price oracle access control vulnerability. The attack is still ongoing.
