On Mar 7, UTC 14:58-14:59, within this 2 minute period, the VIA/BTC market experienced abnormal trading activity. Our automatic risk management system was triggered, and all withdrawals were halted immediately.
This was part of a large scale phishing and stealing attempt.
So far: All funds are safe and no funds have been stolen.
The hackers accumulated user account credentials over a long period of time. The earliest phishing attack seems to have dated back to early Jan. However it was around Feb 22, where a heavy concentration of phishing attacks were seen using unicode domains, looking very much like binance.com, with the only difference being 2 dots at the bottom of 2 characters. Many users fell for these traps and phishing attempts. After acquiring these user accounts, the hacker then simply created a trading API key for each account but took no further actions, until yesterday.
Yesterday, within the aforementioned 2 minute period, the hackers used the API keys, placed a large number of market buys on the VIA/BTC market, pushing the price high, while 31 pre-deposited accounts were there selling VIA at the top. This was an attempt to move the BTC from the phished accounts to the 31 accounts. Withdrawal requests were then attempted from these accounts immediately afterwards.
However, as withdrawals were already automatically disabled by our risk management system, none of the withdrawals successfully went out. Additionally, the VIA coins deposited by the hackers were also frozen. Not only did the hacker not steal any coins out, their own coins have also been withheld.
