Fileless malware
Fileless malware is a type of malicious code used in cyber attacks that doesn’t use files to launch the attack and carry on the infection on the affected device or network. The infection is run in the RAM memory of the device, so traditional antivirus and antimalware solutions can’t detect it at all. Malicious hackers use fileless malware to achieve stealth, privilege escalation, to gather sensitive information, and achieve persistence in the system, so the malware infection can continue to carry on its effect for a longer period of time.
