Dangerous virus

 

Let's find out, what we have to say about ransomware? It consists of a totally legal coding system which changes the data on user’s PC, so customer is unable to utilize them in any approach. That key is also encrypted with a different algorithm. In most cases, scammers prefer RSA and AES manners, which are famous for their complexity and fail-safety. The mentioned methods and the programs based on them are in free access on the Internet, so hackers only need to invent techniques of defense, to block an inlet to a virus, and create the reliable control and update system. Some viruses can function on their own, and scammers get a report of another victim as late as he turns to them and transmits his money. Other ransomwares are function in different way, and send reports to hundreds addresses, to confuse the security specialists and maximize the efforts required to defeat a virus. Ransomware changes file extension to Wtf.

 

Virus sort does not actually matter, as the RSA and AES algorithms are very complex to bruteforce them. It can take centuries to make all required calculations on a modern computer or, maybe, few decades if you have an access to a mega-efficient gear. The best manner to beat a high-quality ransomware is to hack into it, or hack its database, to receive a master key. Rare ransomware examples also have a breaker that can cease virus' activity completely or to make it pass a particular device. If anyone discovers that breaker for this ransomware, or create a decryption tool, we will provide you with full information in this article.

 

There are some possibilities to inspect, until you can give in and wait for a decryption program. As it is written above, scammers also fail, and certain specialties of the system can assist you to restore information.

 

  • If you don't employ the OS from an admin account – you're very lucky. The matter is that your operating system duplicates all files prior to their elimination or modification. Suchlike backups are called SVC, and Dangerous has the methods to remove them. If you're employing the regular entry – the OS requests for a confirmation at the exact moment Dangerous starts to remove these copies. If you saw such request and reversed it – your SVC are secure, and could be used to get back the files.
  • A backup is the only 100% productive method to get the information back, but you need to remove a virus first. Ensure that the virus is uninstalled fully, since if it isn't – all data will be spoiled again, with those that were saved on an outer hard disc.

 

If all of these advice didn't help and there is no way to get back the information – you better delete the virus from the system and expect when a decryptor will be created.

Dangerous is incredibly sly and there is a chance pass some remains and then regret it (for example, when you connect an external drive with your saved information to a not-really-cleared machine).
