Let’s start with DeFi. Governance attacks against DeFi projects can wreck projects if they are not careful or well monitored. Recall the Beanstalk hack earlier this year where an attacker flash loaned enough governance tokens to steal $182M. Luckily Yam Finance was able to catch a malicious proposal to take over project’s treasury by a well financed attacker before it was too late.
On the less fortunate side this week also had two hacks using very traditional vectors: Omni X reentrancy hack and BiFi signing server compromise. To help protection your projects from similar hacks this week’s research section features Certik’s quarterly web3 security report outlining key threats and plenty of smart contract security testing papers.
Multiple security vendors published reports on crypto stealer and crypto miner strains likely indicating new campaigns by bad actors such as the one targeting samczsun.
Let’s dive into the news and be sure to check out the Job Listings section in case you get inspired to make blockchain security your career. Premium Indicators section has attacker addresses for all of the hacks below.
