Convergence DeFi Protocol Suffers Major Security Breach
In a startling turn of events, the decentralized finance (DeFi) sector witnessed yet another significant security breach. Convergence DeFi Protocol, known for enhancing liquidity and returns within the Curve Finance ecosystem, confirmed a devastating attack on its operations. This incident, which unfolded in the early hours of August 1st, led to a catastrophic drop in the value of its native token, CVG, by over 99%.
Details of the Hack
The hacker exploited a smart contract breach to mint and offload $210 million worth of CVG tokens, alongside pilfering $2,000 in unclaimed staking rewards. The attack specifically targeted the CvxRewardDistributor contract of the Convergence protocol. According to the blockchain security firm PeckShield, the assailant swiftly converted the minted CVG tokens into 60 wrapped-Ether and 15,900 Curve.fi FRAX, leading to a near-total devaluation of the CVG token, now priced at a mere $0.0004.
How the Breach Occurred
The vulnerability arose from a critical oversight during a recent update to the protocolโs smart contract. Despite undergoing four separate audits, the Convergence team inadvertently removed a crucial line of code responsible for validating staking reward claims. This oversight allowed the hacker to deploy a malicious contract mimicking the legitimate claimCvgCvxMultiple function, ultimately enabling the unauthorized minting and dumping of tokens.
However, Convergence has issued an apology to its community and stakeholders, acknowledging full responsibility for the breach. Specifically, the protocol has assured that while the CVG token has been severely impacted, user funds remain secure. Therefore, they have advised users to withdraw their assets from the platform as a precaution and promised that the rewards contract for the Stake DAO integration, though currently compromised, will be rectified, allowing users to claim their pending rewards once resolved.
Impact on the DeFi Landscape
The hack has not only affected Convergenceโs operational integrity but has also led to a significant drop in its total value locked, which plummeted from $5.79 million to $3.69 million, as per data from DefiLlama. This incident adds to a troubling trend in the cryptocurrency sector, which saw approximately $266 million lost to hacks in July alone, including a massive $230 million breach at the Indian trading platform WazirX.
