To avoid detection by anti-malware programs, cybercriminals are using fileless malware to initiate attacks. Fileless malware is used to infiltrate trusted applications and issue executables that blend in with normal network traffic, IT processes, and system administration tasks while leaving fewer footprints.

Over the past few years, the security industry has witnessed a rapid evolution in attack techniques, including fileless malware. Now, cybercriminals use legitimate tools and services such as existing software, applications, and authorized protocols to carry out malicious activities like unauthorized data retrieval or data damage.
