The hacker gained access to the resource base through the account of the CryptoTrader.Tax support employee.
As a result, it dumped user data, including names, email addresses, partial information about income from transactions with cryptocurrency and information about profiles in payment systems.
According to CryptoTrader.Tax Co-founder David Kemmerer, the hacker downloaded a file with a database of 13,000 lines, of which 1,082 are unique email addresses.
