Abstract:The decentralized finance protocol Convergence suffered a severe exploit yesterday, leading to a 99% collapse in the value of its CVG token.
In a significant security breach, the decentralized finance protocol Convergence suffered a severe exploit on Thursday, leading to the near-total collapse of its token's value. The attack, which exploited a vulnerability in Convergence's codebase, resulted in the minting of 58 million CVG tokens.
The attacker leveraged the newly minted tokens by swapping them for 60 wrapped ether (wETH) and 15,900 crvFRAX stablecoin using liquidity pools on Curve, according to web3 security auditing firm QuillAudits. Blockchain data from Etherscan revealed that the stolen funds were subsequently converted to ether (ETH) and transferred to Tornado Cash, a privacy-centric mixing service, making the trail of the stolen funds difficult to trace.
QuillAudits reported that the attack led to a loss of approximately $210,000. However, the broader impact on CVG token holders was catastrophic. Prior to the exploit, the fully diluted value (FDV) of the CVG token stood at $17 million. Following the attack, the token's price plummeted by 99%, dropping from approximately $0.12 to a mere $0.0004 in the Curve liquidity pools.
In response to the breach, Convergence issued a notice advising users to refrain from interacting with the protocol until further notice, highlighting the severe and immediate disruption caused by the exploit.
This incident underscores the broader issue of rising cryptocurrency thefts. According to blockchain researchers TRM Labs, the total amount of cryptocurrency stolen in hacks globally more than doubled in the first half of 2024 compared to the same period in 2023. By June 24, 2024, hackers had stolen over $1.38 billion worth of cryptocurrency, up from $657 million during the same period in the previous year. The median theft size also increased significantly, indicating a trend towards larger-scale attacks.
Despite these security concerns, cryptocurrency prices have generally rebounded from the lows experienced in late 2022 following the collapse of Sam Bankman-Fried's crypto exchange, FTX. Notably, Bitcoin reached an all-time high of $73,803.25 in March 2024.
However, the industry continues to grapple with high-profile losses. Earlier this year, Japanese crypto exchange DMM Bitcoin reported a theft of $308 million worth of bitcoin, termed an “unauthorized leak.” Such incidents, while not commonplace, highlight the persistent vulnerabilities faced by cryptocurrency firms.
In 2022, stolen cryptocurrency volumes were approximately $900 million, partly due to the high-profile $600 million theft from a blockchain network associated with the online game Axie Infinity. The United States attributed that theft to North Korean hackers, with the United Nations accusing North Korea of using cyberattacks to fund its nuclear and missile programs, allegations which North Korea denies.
The exploitation of Convergence is a stark reminder of the ongoing security challenges within the cryptocurrency sector. As the industry evolves, the importance of robust security measures cannot be overstated to protect investors and maintain trust in decentralized finance protocols.
