According to Golden Finance, according to the analysis of Slow Fog, Bybit's attack mainly stems from its use of the outdated Safe contract version (v1.1.1), which makes it impossible to use the key Guard mechanism for protection. This loss may be avoided if Bybit is upgraded to 1.3.0 or later and implements the appropriate Guard mechanism, including specifying the whitelist address of the unique received funds and strict contract function ACL verification. Slow Fog emphasizes that although this is only a hypothesis, it provides important ideas for future asset security management.
