Binance, a global cryptocurrency exchange, reported a security breach on May 7, 2019, in
which hackers seized over 7,000 bitcoin (approximately $41 million) in a single
transaction.
Binance stated that hackers obtained user information using
phishing, viruses and other attacks. According to Binance, the
hackers designed the single fraudulent transaction to avoid
triggering its security checks. However, once the transaction was
executed, Binance's security system was triggered and all
withdrawals were immediately suspended.
Binance informed customers it is conducting a thorough security
review that will take approximately one week. During the security
review, all deposits and withdrawals will be suspended, but trading
will be enabled.
