A hacking group known as CryptoCore has pulled off cryptocurrency heists worth $70 million. Research indicates that it may be an estimated value of over $200 million since 2018. The group targets cryptocurrency exchanges by conducting spear-phishing campaigns against employees and executives. It is not completely clear where this hacking group is based, ClearSky believes the threat actors have links to the East European region, Ukraine, Russia, or Romania. Once a victim is infected, the attackers will use the backdoor to attempt to steal keys to crypto-wallets that are commonly stored in password managers.
