The breach of the Okx Dex platform occurred on December 13, with $2.7 million being extracted from its decentralized finance (defi) protocol. This incident was brought to light by various onchain analysis experts. Arkham has since announced the establishment of a bounty to track down the responsible party. Arkham communicated via the social media channel X (formerly Twitter). “We’ve created and funded a bounty to help identify the person or organization behind the recent Okx Dex exploit,” Arkham wrote. “Okx Dex was exploited by a hacker who upgraded a deprecated contract with token approvals, resulting in losses of over $2.7M on Dec 13, 2023. The hacker is tied to a number of hacks, including Lunafi, Uno Re, RVLT, and more.”
