Serving 800 million netizens

If you have been a loyal user of this messaging application, similar reports might simply seem fake. The company has been steadily expanding its network. In 2010, Rakuten bought Linkshare, New York-based utility.

The following year, it launched its utilities designed for Indonesia and Brazil. In 2012, it increased its investments in Pinterest. Viber is also reported to be the official communication platform of FC Barcelona. Additionally, the app is compatible with Android, iOs, Mac and Window operating systems. Thus, what did go wrong?

Previous reports about “Viber virus”

On May 2017, Windows users, who have been using Viber on their PCs, might have got astonished by Windows Defender security alerts. The application was labeled as “Viber malware” and a potential security threat. Some of the third party anti-virus utilities recognized the app as a threat as well.

Interestingly, the app has been already labeled as malware before. Last year users have reported such behavior as well.[5] However, at that time, it turned out to be a false positive. Users have declared app data on their Android phones which solved the issue. Windows users offered reinstallation often software to fix the problem.

At the moment, the recent reports about Viber virus are still under investigation. It would be a great astonishment if the reports turned out to be true. On the other hand, the cases when well-known utilities get compromised are not rare. The cases of Skype and WhatsApp application perfectly illustrate such tendency.

  • Social Media Information
  • Activity Information
  • Information from Other Sources

Thus, it purely depends on you whether you are fine with such use of personal details. Otherwise, you might want to perform Viber removal. One of the options to eliminate it is to use ReimageIntego or Malwarebytes services.

“Viber malware” types from A to Z

Viber prize scamViber prize scam is a fake message which claims that users have won an iPhone and need to enter a four-digital code to receive it

Asprox botnet spread via Viber email scam

There have been reports about a dangerous botnet malware distributing via false Viber notification.[6] The crooks provide victims with a message of a falsely missed phone call from Viber support. The scam announces that the user has a missed call and injects a suspicious hyperlink into the text. If it is clicked, the victim is taken to a malicious web server.

Talking about Asprox botnet itself, this type of malware was created to deliver huge amounts of spam messages. However, it is also known that the botnet can steal credit card and banking information, push ads for pay-per-click revenue, and search for particular flaws in web pages. The hackers always ensure that the victim is running the IE browser and verify the IP before launching an attempt.

The Unexpected Lottery Prize scam

This type of scam targets Viber and WhatsApp users by claiming false things in text messages. Victims of this scam are tricked that they have won a particular prize, for example, the newest iPhone and asks the user to enter a digital code of four numbers. If he/she opts for entering the numbers, hackers might start urging for a particular weekly price that needs to be paid in order to receive the fake prize.

Beaver Gang Counter app steals photos/videos from Viber

Android virus steals information from popular messaging apps, including Viber

Security experts found out that some type of Android malware has been stealing sensitive data from popular messaging applications, including Viber.[8] Researchers claim that this type of virus compromises the “/system/etc/install-recovery.sh” file to execute every time when the victim opens Viber. An interesting thing about this malware is that it includes a particular module that helps to avoid detection and sneak into the device unknowingly.

Safety tip

Viber support has provided some guidance for their users who might have been dealing with various scamming/hacking attacks.[9] The company displays some instructions on how to avoid possible infections and scams. The staff claims notifications from Viber come only from their official website and are not urged to be forwarded to other users:

Viber will never:
Send you an email with instructions to forward it to others.
Send you an email with a link to a website that is not www.viber.com. Do not click on any link that claims to be from Viber or affiliated to Viber but does not use this domain.

Tips to escape app “impostors”

Due to its increasing popularity, there is a low possibility that you might encounter this app in the form of an optional add-on. Likewise, “Viber hijack” does not exist either. The application is available on its official website. In addition, you can also find Viber as a browser-add-on offered in Chrome web store.

Even though the distribution network does not raise concerns, do not exclude the possibility that crooks might exploit the software for their malicious purposes. If you are about to install Viber, download it from its official website. Once User Account Control notification pops up inquiring you about enabling the app, check whether Rakuten Inc is indicated as an official publisher. Do not download the app which presents “unknown” publisher.

How to prevent from getting Viber virus

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
