TechFlow News: On June 9, SlowMist founder Yu Xian tweeted that, based on preliminary analysis, the Asterix attack employed techniques similar to those used in yesterday’s Flooring Protocol incident. The underlying protocols involved are DN404 and BT404, respectively. The issue relates to integer overflow during high-value NFT ID bit-shift operations, leading to ID reuse. Attackers may be actively searching for similar vulnerabilities.
