Term Definition
Radio-frequency identification (RFID)
A generic term to describe a system that transmits the identity (in the form of a unique serial number) of an object or person wirelessly using radio waves.
Malicious software created by a hacker to restrict access to the computer system that it infects and demand a ransom paid to the creator of the malicious software for the restriction to be removed. Some forms of ransomware may encrypt files on the system's hard drive, while others may simply lock the system and display messages to coax the user into paying.
A method used to direct someone or something to a different place than was intended. Cybercriminals can use these to route a legitimate website's traffic to a counterfeit website.
Remote administration tool (RAT)
Software designed to give an administrator remote control of a system. Hackers can install malicious RAT software on a computer without the user's knowledge and take control of it remotely without the user's knowledge. RATs can be installed by opening an infected attachment, clicking links in a popup window, or through any other software that poses as legitimate.
The process by which a virus makes copies of itself to carry out subsequent infections. Replication is one of the major criteria separating viruses from other computer programs.

A way that users of mobile devices (mobile phones, tablet PCs, and other devices running the Android operating system) hack their devices to gain privileged access to the operating system. This gives the user the ability to alter or replace system applications and settings, run apps that require administrator permissions, or perform operations that otherwise would have not been possible.
A stealthy type of malware that is designed to hide the existence of certain processes or programs from normal methods of detection and enable continued privileged access to a computer. Rootkits are the hardest type of invasive software to detect and nearly impossible to remove. As eluded to in the name, they dig into the root of a hard drive. They are designed to steal passwords and identifying information.
