Koobface worm – extremely dangerous virus

Koobface

Since 2009 Koobface has been known as computer worm that spreads on social networks and tries to steal private users’ information. Malware attacks have been spotted on Facebook, Twitter, MySpace, Skype, Yahoo messenger and even Gmail, Yahoo and AOL mailing. Usually, computer infections target only Windows OS users; however, this cyber threat can affect Mac OS X and Linux as well. Koobface malware tries to trick users to install fake Flash Update that is necessary to watch a particular video. Victims receive the video link on direct message on the social network, and if they click on it, they are redirected to a dangerous website which asks to install updates. This bogus update hides Koobface virus which has been created to steal personal and private computer users’ information. Indeed, malware is a serious threat to your credit card and banking credentials, information published on social media and so on. During its lifetime, the developers of the malware have already earned thousands of dollars.

On the affected computer malware checks browser’s cookies and looks for cookies that are related to social media. If malware finds them, it activates itself, steals login information and spreads a malicious message to the entire social media friend list. If Koobface worm got in the ‘wrong computer’ that owner does not use or is inactive social media user, it deletes itself and delivers a fake pop-up message informing about particular codec error and asks to contact the service.

Indeed, Koobface virus can provide lots of misleading advertisements that warns about various computer-related issues, offers software installation or updates. However, these notifications, ads, and warnings are just Tech support scam. If you click on them or even decide to contact cyber criminals, you may be tricked into installing software or giving criminals full access to your computer to solve a particular issue. However, these warnings are an actual sign of computer infection, and you should not ignore them. Keep in mind that it’s crucial to remove Koobface immediately because keeping in on PC may lead to the money loss.

Some cyber criminals use Koobface name in order to scare computer users and swindle their money. Some tech support scammers deliver a pop-up message that computer has been infected with Koobface. To remove it from the system and protect the computer, the user has to call provided numbers. Keep in mind that calling suspicious numbers is not a wise decision. Crooks may trick you into purchasing or installing questionable software and cause more problems for you. They might also convince you to install remote control tools and give full access to your PC for them. If you see suspicious warnings about various computer-related issues, instead of calling to the shady help services, run a full system scan with strong and professional anti-malware application. However, if you do not have it, we recommend installing Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes. These programs are capable of detecting and eliminating malware. Within several minutes Koobface removal will be over.

Koobface distribution and how to avoid it

As we already mentioned Koobface, malware spreads via social media messages and fake video player. Social media users receive an infected video link from a friend which redirects them to the suspicious website, where they are asked to install Flash Updates. If users are curious and have no idea about safe ways to update programs and allows installing fake updates, they let malware inside the computer.

It’s not hard to recognise infected link from the safe one. The dangerous link usually has various symbols, letters or numbers and the domain looks unfamiliar. If the link looks strange or suspicious, do not open it. Victims claim that in the message their ‘friend’ told that they are in this video and encouraged them to watch it as well. Indeed, you can be easily tricked to open the link if you are close to the sender; otherwise, you should think before opening it. It’s doubtful that your colleague or old classmate whom you haven’t talked in ages will send you a funny video.

The only possible way to avoid Koobface virus is to stay away from unreliable and high-risk websites and do not click on any suspicious links or advertisements that you see online. Bear in mind that some viral videos on social may also include malicious content. Do not open any links and videos sent from your friends that look suspicious. Before opening it, double check the information and ask your friend if this link is really safe to open. If you end up on the website that asks to update Flash or install other applications, leave it immediately. Remember, that reliable updates do not show up as pop-ups or ads. Lastly, protecting your computer with strong antivirus program will also help to avoid malware.

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. In this case, you may need to connect to the server from different locations, which is especially inconvenient when your website is protected from unauthorized IP addresses and suspicious connections.

Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. With dedicated/fixed IP, you can connect to your content management system wherever you are without any security issues. Also, in exactly the same way, you will avoid authentication problems when logging in to your bank accounts from different locations.

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Recover files damaged by a dangerous malware attack

Despite the fact that there are various circumstances that can cause data to be lost on a system, including accidental deletion, the most common reason people lose photos, documents, videos, and other important data is the infection of malware.

Some malicious programs can delete files and prevent the software from running smoothly. However, there is a greater threat from the dangerous viruses that can encrypt documents, system files, and images. Ransomware-type viruses focus on encrypting data and restricting users’ access to files, so you can permanently lose personal data when you download such a virus to your computer.

The ability to unlock encrypted files is very limited, but some programs have a data recovery feature. In some cases, the Data Recovery Pro program can help recover at least some of the data that has been locked by a virus or other cyber infection.
