BlockThreat - Week 16, 2023
Trust Wallet | FilDA | Tales of Elleria | KuCoin | KyberSwap | Blur
Greetings!
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.
Trust wallet browser extension was found vulnerable to a weak key entropy vulnerability. Stop reading the newsletter and check if you are vulnerable here! Is this related to the infamous $4m heist in a hotel lobby in Rome?
Let’s dive into the news! Oh and be sure to check out Coinbase Unit 0x Team’s latest deep dive analysis into the Euler compromise in the research section below.
