##### Expert Solution

A RAT is a type of malware that’s very similar to legitimate remote access programs. The main difference, of course, is that RATs are installed on a computer without a user’s knowledge. Most legitimate remote access programs are made for tech support and file sharing purposes, while RATs are made for spying on, hijacking, or destroying computers.

Like most malware, RATs piggyback on legitimate-looking files. Hackers can attach a RAT to a document in an email, or within a large software package, like a video game. Advertisements and nefarious webpages can also contain RATs, but most browsers prevent automatic downloads from websites or notify you when a site is unsafe.
