Ransomware (Tutorial) - Bonus: Decryption Steps Ransomware Removal Guide

What is Ransomware? – ransomware which has similarities with Dharma virus and Crysis Ransomware - ransomware which is familiar with Dharma Virus and Crysis ransomware. is ransomware[1] which seems to be a mixture of Dharma Ransomware and Crysis Ransomware. Researchers have discovered that the operating principle of virus is the same as Dharma's but its code is from Crysis. This mixed virus was discovered in the second week of September. The ransomware encrypts files by adding the .[].brrr extension to each corrupted document. After that, the virus displays a ransom note that urges a particular price for the decryption key and offers 1 file for free decryption as proof.

If such thing happens, your computer security level will decrease even more and you might face various damaging consequences such as deactivated software, system struggles, etc. Due to such possibility, you need to get rid of ransomware ASAP.

Moreover, Ransomware uses a secret code such as an AES or RSA cipher to lock important documents. The algorithm includes a different code each time the ransomware-type virus infects a new computer. Additionally, cyber crooks store both encryption and decryption keys on safely kept remote servers that are out of reach for other people, except themselves.

Ransomware-type viruses are very likely to demand cryptocurrency such as Bitcoin for the urged price. We can see from the ransom note that Ransomware also demands Bitcoins and the crooks state that the ransom amount will depend on the time when the victim shows contact:

There should be no hesitation as the longer you keep this threat the bigger the damage will be. Moreover, you can use FortectIntego to repair the damage that has already been done by the ransomware.

Better perform the removal than consider paying the demanded ransom. Even though if you transfer the urged money, there are no guarantees that you will receive the decryption tool. According to malware researchers[3], users are very likely to get scammed by such criminals who do not fulfill their promises but only give them to trick victims and receive money. - a file locking threat which uses algorithms such as AES and RSA to corrupt documents on the infected PC.

Stay away from dangerous ransomware infections

The most popular ransomware distribution technique is by spam messages. Crooks drop hazardous payload attached to a phishing message which is sent to numerous random users. If you ever receive a questionable-looking message in your email box, and if you are not expecting anything important recently, you should get rid of the spam email permanently. DO NOT open any attachments if there are some clipped to the phishing letter.

Furthermore, ransomware can be distributed through third-party networks. P2P websites are one of them. These types of pages lack required protection and might secretly install a hazardous virus on your computer. Be aware of secondary sources. Moreover, get a reliable computer security tool to protect your system at a higher level. Such program needs to be updated once in a while in order to carry out its functions properly.

Terminate ransomware

If you have spotted files with the .[].brrr extension, you can be sure that your computer is infected with a dangerous ransomware and it might even infect your system with a Trojan. You need to remove virus as soon as you spot the first signs. Do not hesitate as the longer you wait, the bigger problems it will cause and the damage will become even harder to repair.

You should perform the removal by using only trustworthy and expert-tested anti-malware programs. We suggest taking care of the cyber threat by downloading and installing FortectIntego, SpyHunter 5Combo Cleaner, or Malwarebytes. After the process, make sure you carry out some system backups. This will ensure you that the virus has completely vanished.

Manual elimination is not possible for this case as it might be a very difficult process. Low-experienced users and even some experts might find the elimination hard to handle on their own. Additionally, you need to perform the Ransomware deletion before you take care of encrypted data. Otherwise, your work will give no results as the cyber threat will corrupt your files again.

How to prevent from getting ransomware

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.
