SlowMist Cosine: 402Bridge attack was caused by private key leakage, insider involvement cannot be ruled out

According to ChainCatcher, based on analysis by SlowMist Cosine, the attack on the cross-chain bridge project 402Bridge was caused by a private key leak, and the possibility of insider involvement cannot be ruled out.

The 402 bridge.fun domain was registered for only two days before ceasing service, and the stolen funds have not shown any further movement so far. This is the first publicly reported security incident related to the 402 protocol services. SlowMist Cosine stated that this incident is not a typical case of collective wrongdoing by the project team.
