Fileless malware attacks, which were recently discovered in the networks of at least 140 banks, telecoms and governments, account for about 15% of known attacks today and have been around for years in different forms.

"Fileless malware attacks are becoming much more common and circumvent most of the endpoint protection and detection tools deployed today," Gartner security analyst Avivah Litan said.

A recent discovery of fileless malware was reported on Wednesday by researchers at Moscow-based Kaspersky Labs. The attackers have not been identified and "attribution [is] almost impossible," according to Kaspersky.
