Fileless Malware: The What & How
Fileless malware operates in a computer’s memory without leaving any trace on the hard drive as a type of malicious software. Fileless malware uses native and legitimate tools already present on a system to carry out an attack, making it difficult to detect. The attackers gain access to the victim’s system first and steal credentials, then creating a backdoor for persistent access. The malware then gathers data and transfers it out of the victim’s environment.
