In short

The operation originated in June when malicious Google ads and fraudulent job assignments tricked Binance engineers into installing malware that established persistent backdoor access. Attackers eventually co-opted an internal AI platform to manipulate employee wallets, making it difficult to halt unauthorized transfers due to the absence of a single master private key. CEO Richard Teng announced that withdrawals have broadly resumed after roughly $2.85 billion in digital assets was intercepted or frozen.

The largest crypto theft to date was pulled off by combining some well-known hacking techniques over the course of a few months, according to Binance. A postmortem from the company says the process that started with one developer downloading a tampered installer in June apparently spread by a malicious Google ad, exposing details about the engineers and how they work. Then, in September, another engineer was targeted by someone pretending to be interested in hiring them, who set up a series of calls and multiple rounds of interviews, sharing social media pages to build trust, and eventually prompting them to download a fake interview assignment that was actually malware.
