Hackers spent months infiltrating Binance through fake job interviews, malicious software and compromised internal tools before stealing $6.34 billion in cryptocurrency from the world’s largest crypto exchange, according to a security report released by the company on Tuesday. The October 29 attack targeted computers belonging to three software engineers, eventually giving attackers access to systems responsible for authorizing wallet transactions. Binance’s investigation revealed a coordinated operation that began with a compromised software download in June, escalated through a fraudulent recruitment campaign in September and culminated in one of the largest crypto heists on record.
