Hey folks,
This week featured two attacks targeting DeFi users. The massive Uniswap airdrop phishing attack was successful enough to call attention of CZ and other crypto celebrities. Unfortunately, a quick check of your wallets will likely show a dozen unknown tokens sent as part of previous airdrop campaigns. Following a series of DNS hijacking in June, attackers managed to compromise PREMINT server itself and post a malicious approval contract to steal users’ tokens. Not fun at all and once again reinforces the need for stronger wallet-side defenses to protect us.
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.
