BlockSec: The reason for the attacks on SwapNet and Aperture Finance is insufficient input validation leading to arbitrary calls.

Techub News reports, according to BlockSec monitoring, the root cause of the SwapNet and Aperture Finance hacking incidents lies in insufficient input validation in the victim contracts, which exposed arbitrary call capabilities. This allowed attackers to abuse existing token approvals and call transferFrom to steal assets. The two projects lost approximately $17 million on January 26 due to security vulnerabilities.
