Werte in diesem Artikel
Blockchain security firm Dedaub released a post-mortem report on the Cetus decentralized exchange hack, identifying the root cause of the attack as an exploit of the liquidity parameters used by the Cetus automated market maker (AMM), which went undetected by a code "overflow" check.According to the report, the hackers exploited a flaw in the most significant bits (MSB) check, allowing them to manipulate the values for the liquidity parameters by orders of magnitude and establish relatively large positions with a keystroke. The Dedaub security researchers wrote:"This allowed them to add massive liquidity positions with just one unit of token input, subsequently draining pools collectively containing hundreds of millions of dollars worth of tokens."The incident and the post-mortem update reflect the unfortunate trend of cybersecurity exploits and hacks impacting crypto and the Web3 industry. Executives in the industry have continually warned that industry firms must establish safeguards and protect users before regulators clamp down and impose safeguards on the industry.The flawed MSB check.
