How to uninstall/remove mackeeper from macbook
Koobface incorporates two of the most popular malware techniques, social media messages and fake Flash updates, to rapidly spread from one device to another, forming a botnet that can distribute more malware and generate revenue for the scammers who created it. It can be disabled, as with most malware, and we’ll show you how, but the safest approach is to avoid it altogether.
1. Don’t click on links in social media or instant messaging messages unless you’re sure where they’re coming from and where they’re going. Keep in mind that scammers sometimes make it seem as though messages have come from friends.
2. Never click on a link in a pop-up that says your Flash Player or other program is out of date. If you do use Flash, System Preferences is the only place to update it.
4. Ignore social media messages that say your machine is in danger unless you click on a connection or download a piece of software. In hoaxes, Koobface was used to scare users into installing other malware.

The majority of social networking spams and scams spread when users unwittingly recommend them to their friends. Koobface is special. It actively infects your computer and then spreads itself across social networking sites.
Yeah, indeed. Koobface is referred to as a zombie or bot. Infected computers interact with so-called C&C (command-and-control) servers on a daily basis to upload stolen data or receive instructions on what to do next.
Like other zombie networks, Koobface provides a general-purpose command that allows the botmasters (cybercriminals in charge of the botnet) to order your PC to download and run whatever other program they want. Never download video player software only to get an update from a website. Instead of trying to trick you into installing something they want, reputable sites will clarify what you need so you can find it yourself.
For example, the FBI announced Operation Trident Tribunal in 2011 as a two-year anti-cybercrime operation. It took law enforcement from 12 different countries: the United States, Ukraine, Latvia, Germany, the Netherlands, Cyprus, France, Sweden, Lithuania, Romania, Canada, and the United Kingdom.

Old computer viruses and worms are still as dangerous as they were when they first appeared, and they may even be making a comeback. As cybercrime defenses improve, some experts predict that cybercriminals will resort to old tricks like the Koobface malware (also known as a worm or a virus), which infiltrates networks and steals data using social engineering and phishing.
The use of social media is a primary goal. Initially, Koobface invaded Microsoft, Mac, and Linux email, VOIP (such as Skype), and social networking sites. It was primarily reported in the United States and Australia, with a few mentions in Europe. The FBI estimated that social media was used to commit 18,712 cybercrimes in the United States in 2016 (the most recent reporting period), resulting in $66.4 million in damages.
Another Koobface strategy involves generating revenue through pay-per-click advertising while directing traffic to spoofed websites, including some that claim to provide fake antivirus protection. Other variants redirect you to YouTube or a similar site, then say that you need to upgrade Adobe Flash or a plug-in to continue. Others may give you friend requests from people you don’t know, or they may ask you to solve CAPTCHAs (popular challenges to show you’re not a robot) so that the results can be used to target other computer systems.

A DNS filter software that blocks links to well-known security websites, as well as a proxy tool that allows the attackers to abuse the infected PC, are among the components downloaded by Koobface. Limbo, a password-stealing software, was once used by the Koobface gang.
