What is Pcqq Ransomware

Pcqq is a new file-encrypting program developed and published by STOP/DJVU family. Almost all versions entitled to this group of extortionists employ similar steps to extort money from victims. Once Pcqq gets on your PC, it runs a quick scan of your system to find sensitive data. Then, once this process is done, the malicious program gets to encrypting your data. During this, all files are changed with the “.pcqq” extension, which appears at the end of each file name. For example, a file like 1.pdf will change to 1.pdf.pcqq, and similarly. Once you spot such an immediate change, you will no longer be able to access the data. In order to decrypt it, cybercriminals instruct victims through the steps listed inside of a text note (_readme.txt), which opens at the end of encryption. All recent versions of this ransomware family have used identical text in the notes.

Unfortunately, considering that Pcqq is a new infection, no way to decrypt your data for free has been found just yet. There is no guarantee that it will appear any time soon because STOP Ransomware uses strong encryption algorithms that deny any third-party attempts to decode the cipher. The only possible solution to avoid paying the ransom is to recover your files from a backup copy. If you have one stored on other devices or cloud services, you should delete the virus and restore your files. If you do not have such an option available, we are still going to show you some of the steps that may help you recover some portion of the compromised data (down below).

How Pcqq Ransomware infected your computer

Ransomware infections are highly dependant on inexperienced users. This means that less experienced people are more likely to catch such an infection by accident. Usually, most cases happen within e-mail environments. Cybercriminals send a number of identical messages with malicious attachments. These messages are commonly detected as spam getting into junk folders immediately. Despite this, some users get overcurious and open the content attached inside of such letters. Most popular are MS Office documents, PDF, executable, JavaScript, and other file types that cover malicious activity. Since these file formats are generally legal, most users trust and open them eventually. However, when it comes to distributing malware, such files are easy to change and reconfigure for storing a virus. The attached links leading to external resources may also be a potential source of infection. Our advice is to avoid trusting unknown content received for no reason. Most people find fake delivery letters, which claim to deliver your package. If you did not order anything from the web, there is no way you could be contacted by actual services. This is why it is quite easy to say if the content is fake or not. Besides being distributed via e-mail services, ransomware has a number of channels like trojans, file-sharing websites, backdoors, keyloggers, fake software cracking tools, and more. Being more careful and awareness-equipped will help you prevent such damage in the future. Follow our guide below to learn more about protection and recovery tips.
