BlockThreat - Week 16, 2023
Trust Wallet | FilDA | Tales of Elleria | KuCoin | KyberSwap | Blur
At least $1.3m were stolen this week from various DeFi projects, vulnerable wallets, phished users, and more. Price oracle manipulation rings again and again as the primary root cause for most of these hacks. What’s causing protocol designers to miss this vulnerability? Is it deficiencies in the software development process, tools, education? Sounds like a great vulnerability class to focus on for defenders.
