At least 140 banks, telecoms and governments have been infected by “fileless malware” attacks. These exploits have been used by unknown cyberthieves to steal from ATMs and customer accounts. The attackers have not been identified and “attribution [is] almost impossible,” according to Kaspersky Labs. The latest threat was originally discovered by an unnamed bank’s security team that found malicious code inside the bank’s domain controller, a kind of server that responds to security authentication requests.
