On July 11, Crypto Exchange 'Cashaa' claimed that the hacker attacked one of its Blockchain wallet, which is used to store bitcoin (BTC) and make transfers from the exchange.
The attacker is believed to have implanted malware into one of the exchange’s computers. And as an employee accessed the machine the afternoon of July 10 to make two distinct transfers, the hacker pounced, making off with 336 BTC, valued at more than $3.1 million at current market prices.
