CryptoCore executes its attacks by accessing crypto wallets owned by exchanges and employees. The group begins with a “comprehensive discovery phase against the company and its employees”.The gang emails an administrator and phishing attack from the account where they appear to be a senior employee from the same manager or a partner company.
After infiltrating the network, the gang installs malware and provides access to administrator accounts where all keys of crypto wallets are stored. Then they wait for a while and withdraw the money from their wallets by “reacting instantly and quickly” when multi-factor authentication is removed.ClearSky said these attacks fell in the first half of 2020, with a possible cause being the COVID-19 outbreak. He added, however, that “he has not stopped completely.” You can find the detailed report of the security company here .
