U.K.-based algorithmic market maker service Wintermute becomes the latest victim of decentralised finance (DeFi) hacks when its protocol suffered a breach early on Tuesday, September 20, 2022, with hackers making off with around $160 million across 90 assets within the platform’s portfolio.
The news of the breach was announced by company CEO and founder, Evgeny Gaevoy, on Twitter. He stated that “We’ve been hacked for about $160M in our defi operations. Cefi and OTC operations are not affected.” While Gaevoy said that around $160 million was taken by hackers, he noted that “out of 90 assets that have been hacked only two have been notional over $1 million (and none more than $2.5 M),” and as a result a “major selloff” of assets should not occur. According to data from Etherscan, over 70 different tokens have been transferred to “Wintermute exploiter,” including $61, 350, 986 in USDC, 671 in Wrapped Bitcoin, and $29, 461, 533 in USDT.
CEO: Company Remains Solvent
The CEO assured the company’s users, lenders, and partners that the platform is “solvent with twice that amount of equity left.” Associated entities should expect full restoration of operation over the next few days. Gaevoy added:
If you have a MM agreement with Wintermute, your funds are safe. There will be a disruption in our services today and potentially for next few days and will get back to normal after.
According to the company’s CEO, the platform is still willing to treat the incident as white hat hacking, meaning it is willing to engage with the attacker. In this instance, the hacker would be required to return the funds, but would also be allowed to keep a percentage as a bounty. The hacker may also contact Wintermute to share the vulnerabilities they have discovered to avoid a repeat of hacks in the future. White hat hacking has become commonplace in the crypto market, even more so in the bear market. Exchange, market markets, and companies often reward hackers with bounties in the form of cash or job opportunities.
