Here's a summary of the preliminary investigation report on the Binance hack: 1. In June, a wallet operations engineer searched for a popular AI programming tool on a search engine but ended up downloading a tampered installation package. His and his wallet team colleagues' identities were thus exposed to hackers. 2. In September, another engineer was scheduled for two fake interviews on a job recruitment platform. Following the interviewer's instructions, he downloaded a "homework" code file to his work computer, which contained a zero-day malware undetectable by antivirus software. 3. On October 20th, the hackers used this computer as a springboard, leveraging Binance's internal AI tools, to gain control of the computers of two other wallet engineers. After obtaining the signing service on October 29th, they carried out their attack, involving approximately $6.34 billion. Through this sequence of events, you'll discover a crucial point: Never, ever download potentially risky programs or documents from the internet or emails!
