blue) to install a back door, through which Wannacry would be downloaded. Ransomware is the latest generation of malware, which attacks both data and pocketbook. Data is the most valuable asset on computers. The business model for ransomwhere is demanding money in exchange for the return of user data. In some cases, the data is encrypted, but in other cases, there is simply a fake message displayed to that effect. Crypto-malware encrypts everything not including the OS, so that the user can be presented the false message. By using an untraceable payment system and public key cryptography, it is impossible to decrypt the data or to track them down. Those who maintain offline backups of their data are protected from this technique. One way to prevent crypto-malware from executing is to have anti-virus software recognize the malware, which requires that the software has the latest signatures. Trojans and Remote Access Trojans (RATs) take advantage of users when they least expect a problem. Trojan horses are applications that pretend to be something other than malware to entice the user into running it. If the anti-virus software is already aware of a specific Trojan, it will stop it from executing despite the user's mistake. If not, the Trojan horse will get into the computer and open a backdoor to allow other malware in. Many kinds of software that did not begin as malware have backdoors which can be exploited by malware.

One category of a Trojan horse that sets up a backdoor and begins to provide administrative access to your computer is a remote access Trojan (RAT). These RATs (Remote Administration Tools) are often downloaded with other types of software, and once you execute that software, they embed themselves into the OS. This allows a third party to access the computer, setting up other kinds of malware. One way to prevent RATs from being installed is to examine any software that is installed. Do not trust anything you download, and make sure that anti-virus is up-to-date.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
