The $20 Million Heist: Sonne Finance Grapples with Major Crypto Theft
Chronology of a Crypto Heist
The Web3 security firm Cyvers first detected the breach on the evening of May 14, around 10:30 pm UTC. They observed unusual activity targeting Sonne Finance’s digital contracts. Despite the swift detection, the hacker had already executed their moves swiftly and stealthily, draining significant crypto assets including WETH, Velo (VELO), soVELO, and Wrapped USDC (USDC.e) by the time they alerted Sonne Finance 25 minutes later.
By the early hours of May 15, Sonne Finance had publicly acknowledged the breach, announcing on social media platform X that they had halted all trading on the Optimism network. They implemented this pause as a preventive measure to avoid further losses and to begin an in-depth investigation in collaboration with Cyvers.
Efforts to Mitigate and Recoup Losses
Sonne Finance is currently exploring various strategies to recover the stolen funds, following their decision to suspend activities, as indicated by the Sonne Finance Suspends Operations update. One conventional approach in such scenarios is negotiating a bug bounty with the hacker, where the hacker would return the majority of the stolen assets while keeping a fraction as a reward for exposing the security flaw. However, initial indications suggest that the hacker is not interested in such negotiations. Blockchain analysis firm PeckShield reported that the hacker has already transferred $7.8 million to a new wallet, thus complicating recovery efforts.
The hacker’s subsequent transactions involved converting 59 Wrapped Bitcoin (WBTC) into approximately 1,185 Ether (ETH) and 183,000 Dai (DAI), hinting at plans to launder the money through privacy-focused protocols like Tornado Cash, which obscure the origins of funds. In response, this movement of funds indicates potential laundering attempts, and as a result, it prompts further vigilance and action from cybersecurity teams to track and possibly intercept these transactions.
Underlying Security Flaws Exposed
A post-mortem analysis by Sonne Finance revealed that the exploit was a donation attack targeting their Compound v2 forks, which had known vulnerabilities. This revelation has sparked intense debate within the crypto community, with some users accusing Sonne Finance of negligence for using a vulnerable protocol.
In a related development, the main hedge fund of BlockTower Capital, a major player in crypto institutional investment, also experienced a security breach around the same time. While the details and scale of the BlockTower incident remain under wraps, the firm has engaged blockchain forensic experts to trace the stolen assets and understand the breach’s mechanics. This incident underscores the growing concerns over security in digital asset management, as highlighted in a recent article on blockchain’s role in enhancing supply chain security.
Broader Implications for the Crypto Industry
The Sonne Finance hack is a stark reminder of the persistent security challenges in the decentralized finance (DeFi) sector. As the industry continues to evolve, the need for robust security measures and rapid response strategies becomes increasingly critical. This incident may prompt other platforms to reassess their security protocols and consider more rigorous measures to protect investors’ assets.

As the situation develops, the crypto community remains vigilant, watching closely how Sonne Finance navigates this crisis and the measures they implement to safeguard against future attacks. The outcome of this incident could very well set precedents for security practices and crisis management in the burgeoning world of cryptocurrency and blockchain technology.
