Fileless malware

Fileless malware is a type of malicious software that runs on your computer without using files. It usually works by exploiting bugs in your computer's operating system, allowing the hackers to take control over your computer without you knowing. It's sneaky because it doesn't leave behind any files that you can see, so it can be hard to detect. To protect yourself, it's important to keep your computer up to date with all the latest patches and security updates, so the bugs won't be there for the hackers to exploit.
