Guarding Against Fileless Malware: Types and Prevention

Fileless malware uses legitimate system programmes to infect devices, making it tricky to detect. Variants include memory resident malware, Windows registry resident malware, rootkits, exploit kits, fileless ransomware and breaches through false credentials. The malware typically gains access and persists through social engineering, such as phishing emails and exploiting corrupted credentials. To prevent attacks, system updates and patches should be regular, native operating tools monitored and systems observed for unusual activity.
