Koobface worm infection

Koobface is a relatively old cyber infection that targets Windows, Mac OS X, and Linux platforms.[1] Operating as a worm, this malware is capable of intercepting traffic,[2] inducing ads, stealing sensitive information, downloading secondary payloads, and many other malicious activities.

Koobface is also a worm that is capable of spreading via social media and email networks, in particular, Facebook, Twitter, Skype, Gmail Yahoo Mail, and others. As soon as the infection is populated, it checks if there are cookies of social networks[3]. If it locates them, it infects the victim’s profile[4].

If Koobface virus can’t find evidence of social networking websites, it merely erases itself and then loads pop-ups that look like MS Windows error messages. The pop-ups contain the following details: “Error installing Codec. Please contact support.” The threat is flagged by different vendors as W32/Koobface, W32/Koobface.AZ, W32.Koobface and Boface.

If computer user actively uses social media networks, Koobface detects particular cookies and collects victim's login information of all social media websites that he or she visits. Then it sends messages to people on the victim's friend list, asking to view a video.

This message includes a malicious hyperlink. If people click on this hyperlink, they are going to be redirected to a harmful website, which states that an update of Flash is required in order to review the content. The download links include flash_player.exe file. If the person allows installing the update, he/she gives access for an installer of Koobface. It means that this .exe file is going to silently download and install Koobface infection files.

Koobface hacking worm[5] allows the cyber-criminals to track and record sensitive data about the victim, for example, it can see what passwords do you enter on particular websites, what are your logins and it can even find out credit card info and banking information! Be aware because it can lead to a financial loss. In addition to that, this malicious worm can display vague ads convincing you to install fake anti-virus programs. Do not install any software promoted by Koobface virus hoax – most likely you will infect your computer even more.

Beware of tech support scammers who claim that your computer has been infected with KoobFace malware. Technical support scammers make victims install a malicious program that displays pop-up messages via the user's default web browser, stating that the system has been compromised.

Such malicious programs can display a lock screen and prevent the user from accessing the PC or pose as a phony Windows Update. All of these deceptive programs are designed to showcase the technical support number that the user supposedly needs to call in order to get help from “certified technicians.” If your computer is telling you that the system is infected with Koobface, and urges you to contact the tech support team, better scan the system for malware. We also strongly recommend reading this article – Tech Support Scam virus.

Distribution of the Koobface

Koobface is usually spread via social engineering. It means that it is spread via social media messages. If your friend has sent you a link that looks suspicious (looks unfamiliar and contains a lot of random symbols), you should double-ask your friend if he/she really sent that. Such spam usually includes such and similar lines:

  • “I saw your silly face in that movie, check it!”;
  • “Why do you look so stupid? xD See yourself”;
  • “You look just awesome in this new movie”;
  • “My friend caught you on hidden cam.”

If you can remember clicking any of these messages, make sure that you double check your computer for Koobface malware. Also, you should scan your computer with the powerful anti-spyware if you have been tricked into downloading a fake version of Flash Player, which was disguised as “flash_player.exe”.

Koobface scamCrooks are often using Koorface's name in order scam users and make them install bogus software or pay for fake tech support services

Otherwise, Koobface can try to overtake your HTTP traffic, steal your personal information and infect your PC system with additional malware. If you think that you are infected, please, scan your computer with Reimage Reimage Cleaner Intego. You can find more about removal below.

The gang behind Koobface malware shows off their earnings online

While the majority of cyber criminals tend to stay underground and not brag about the money[6] they earn in illegal ways, criminals behind virus behave in an entirely different way. According to research, cyber criminals who have created Koobface project have earned thousands of US dollars daily – up to $10,000 a day.

These criminals were so proud of themselves and loved money so much so that they all have set their phones to deliver a message telling how much money has been earned in the previous 24 hours every morning. Bad actors have also been spotted swaggering on social media and posting pictures next to money piles and Porsches.

Do not let scammers take advantage of you and protect your computer in advance to avoid malware attack. Please, do not click on suspicious-looking links while browsing social media websites and do not open links sent by your friends that point to a video that has nothing to do with you. 

Koobface prevention tips:

  1. Do not browse unreliable websites. If you have opened a website which asks to update your Flash Player, and you know that it was possible to open other videos before, you should know that the site is suspicious. Close it immediately.
  2. If you have at least the smallest suspicion that your friend did not send the suspicious message with a hyperlink, ask him or her twice.
  3. Keep an anti-malware program on your computer to prevent infectious computer threats; we recommend Reimage Reimage Cleaner Intego.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
