As far as I know, Binance has very strict internal security requirements. Downloading unknown files on work computers is strictly prohibited, and clicking on unknown external links is strictly forbidden. However, no matter how strict the rules are, they ultimately need people to enforce them. An employee still employed and concerned about their career prospects will usually care about these regulations. But if someone is already planning to leave and has little regard for the company, they are indifferent. A record-breaking security crisis can begin with a seemingly insignificant oversight. This is shocking and thought-provoking. In the AI era, hacker techniques are evolving at an unimaginable pace, and the security of various exchanges faces even greater challenges and tests.
