Description of CryLocker ransomware virus

General review of the CryLocker ransomware virus

CryLocker ransomware virus pretends to be a fake institution called the Central Security Treatment Organization. Hundreds of victims received a frightening message that all their files were encrypted using a persistent military-grade crypto algorithm. CryLocker virus has similar characteristics as recent ransomware infections: after infiltrating computer’s system, it encrypts the data, changes desktop background and puts the ransom note. In the ransom note, crooks ask to pay 1.1 Bitcoin (500 GBP) in order to get their locked files back. However, they should hurry up, because, after a while, the price will be doubled. The hackers try their best to convince victims that there’s no other way to recover the files. Nevertheless, there’s no free and reputable file decryption tool created yet; we do not advise paying the ransom. Hackers rarely help victims to recover the files. They are only interested in taking the money. If your computer was infected with this malware, your first and the most important task is CryLocker removal. Only when you get rid of the virus, you can try to restore your data from backups. It’s the only possible option at the moment. The virus deletes Shadow Volume Copies that might be useful in data recovery.

Latest information shows that the CryLocker virus spreads via Sundown exploit kit. Once it gets inside, it starts file encryption and appends .cry file extension to all corrupted files. Then, it leaves a ransom notes Recovery_[random_characters].html and !Recovery_[random_characters].txt files, and changes desktop picture. The new desktop background has a threatening message that all users’ files were encrypted. It seems hackers want to motivate victims to pay the ransom by finishing the message with Albert’s Einstein's’ quote. However, this virus is not a joke and you should take it seriously. CryLocker use Command and Control servers to collect information about computer’s operating system and determines user’s location with the help of nearby Service Set Identifier (SSID). Besides, it stores information about the victims on Imgur.com and Pastee.org. There’s possibility that hackers have secret purposes of gathering other personal or even private information. For your safety, you have to remove CryLocker from your PC immediately. For doing this, you might need professional anti-malware tools such as ReimageIntego.

How does the ransomware spread?

Usually, ransomware type viruses spread via spam emails. Infected emails often have attachments. The crooks convince victims to open the attachment, and once they do it, the virus sneaks inside. If you want to avoid CryLocker malware and other ransomware viruses, you should be careful with your emails. Do not open any spam emails or emails which have an unknown sender. Moreover, the crooks might pretend to be representatives from an official and reliable institution. So, you have to be very careful and attentive, if you receive a suspicious email that encourages you to open the attached file. According to the latest information, the virus spreads via Sundown exploit kit. Also, if you want to protect your computer, you have to pay attention to software downloads and installation, stay away from suspicious advertisements and install a powerful antivirus program.

How to prevent from getting ransomware

Prevent the government from spying on you

As there is a growing debate in government about collecting users' data and spying on citizens, you should take a closer look at this issue and find out what shady ways of gathering information can be used to collect information about you. You need to browse anonymously if you want to avoid any government-initiated spying and tracking of information. 

You can enjoy secure internet browsing and minimize the risk of intrusion into your system if you use Private Internet Access VPN program. This VPN application creates a virtual private network and provides access to the required data without any content restrictions.

Control government and other third party access to your data and ensure safe web browsing. Even if you do not engage in illegal activities and trust your ISP, we recommend being careful about your security. You should take extra precautions and start using a VPN program.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
