The latest signatures, careful installation of applications, and regular backups can protect from adware and spyware. Botnets are a specialized kind of malware. There is a virtual robot inside of the computer performing functions that are being commanded to it. This robot networks with similar robots in other devices. Typically, botnets use Trojan horses to enter systems. Once botnet software installs itself onto your

computer, it waits for commands from a centralized command and control system. One well-known botnet is the ZeuS botnet. It took money from bank accounts and transferred it over to the hackers. There are many different kinds of botnets, and there's botnet activity happening constantly. The developers of botnets can have them operate as one large entity. They can send comands and have all the devices perform those commands simultaneously. This is often used in a distributed denial of service attack. The botnet developers will rent out time on the botnets to bring down websites in DDoS attacks. Stopping a botnet is similar to stopping any other malware. Keeping the OS and applications updated can prevent infection. Proactive scanning will detect one. It's also useful to monitor the network for unusual incoming or outgoing traffic. The right firewall can prevent the botnet from ever receiving commands. Logic bombs are one of the most difficult types of malicious software. They wait for an event and then do something devastating. They are often time bombs, waiting for specific conditions (e.g. backup process). They are difficult to identify, because they don't match a known signature of anti-malware software, and are installed by admins. A logic bomb in the form of a seemingly legitimate bank email occured on March 19th, 2013 in South Korea. A day later, the logic bomb exploded, deleting boot records and presenting a message upon reboot that a boot device was not found. Many customers were unable to access funds through ATMs.

    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.
