After losing $3.8 million in a Sept. 27 hack that exploited a known but unaddressed security vulnerability, decentralized finance (DeFi) protocol Onyx received community approval to relaunch its open-source, permissioned financial network, Onyx Core as a key product to strengthen its governance.
The Onyx Improvement Proposal “(OIP)-46: Relaunch Onyx Core” was <a data-ct-non-breakable="null" href="https://community.onyx.org/t/oip-46-relaunch-onyx-core/1795" rel="null" target="null" text="null" title="null">introduced</a> on the same day, shortly after the <a data-ct-non-breakable="null" href="https://cointelegraph.com/news/onyx-protocol-exploited-second-time-3-8m-via-known-bug" rel="null" target="null" text="null" title="null">$3.8 million security exploit</a>. The proposal called for major changes to the protocol and its product offerings, including shutting down its Ethereum-based lending market and reimbursing the lenders “in full at a 1:1 payment of the assets they supplied.”

The restructuring will also involve running the Onyx Protocol as a closed-ended lending protocol on Onyx Core, allowing users to wrap non-fungible tokens, real-world assets (RWA) and crypto assets.
The Onyx hacker manipulated an NFTLiquidation contract to inflate the self-liquidation reward amount. According to blockchain security firm PeckShield, the vulnerability was previously used to attack Onyx in October 2023.&nbsp;

According to Web3 cybersecurity company Cyvers, losses from crypto hacks in the first three quarters of 2024 exceeded $2.1 billion.
Centralized finance operators such as crypto exchanges were the biggest target, with a 984% year-on-year increase in the first three quarters of 2024. Much of that came in the year’s second quarter when $401 million was lost.
While losses in the DeFi sector dropped 25% year-on-year in Q2, the sector still saw $171.3 million lost from 62 incidents.
