Binance hack - who is behind it, is my money safe and what we know so far

The hack happened to Binance's global centralised exchange, Binance.com.

Binance.us, which provides trading services specifically for US residents, said it has not been affected by the issue.

In a statement, Teng said: "Our initial investigation suggests this security incident may have started with a compromised DevOps engineer's laptop.

"That gave an attacker access to a service container, where they submitted unauthorised withdrawal transactions."

He said the hack "was not a simple 'one-click' action" but a "more complex attack process".

Raghu Nandakumara, vice president of industry strategy at cybersecurity platform Illumio, said this could mean an engineer was "talked into taking a test" and malware - malicious software – "landed on their laptop while they did it".
