Slow Mist Cosine: Preliminary analysis of Orbit Bridge is not that the private key was directly stolen, but more likely a vulnerability in the bridge

SlowMist founder Yu Xian tweeted that Orbit Bridge suffered a loss of at least $81.5 million. Preliminary analysis suggests that it was not a direct theft of private keys (although this possibility cannot be completely ruled out), but rather a vulnerability in the bridge or related centralized server that allowed attackers to deceive these private keys (7/10) to withdraw. Yu Xian also stated that the hacker's address can be viewed and pointed out that the hacker was preparing two days ago.
