Pulsar1 ransomware virus

Pulsar1 is a new exemplar of widespread DJVU virus. This ransomware like fungus, it make new extensions everyday: Chark and Sobid are the latest and it's only last week. The work principles are absolutely the same: virus adds to each file: pulsar1 extension. The rules are set out in _readme.txt file. Hackers wants 490$, but if victim doesn't pay for 72 hours, sum will be doubled. This virus uses Malspam compains primaryly and cheat users by suggesting them fake letters from their partners for example. 



The encoding programs, also called ransomware, are the viruses that penetrate your devices and waste their information to gain money for its restoration. Typically, hackers get on victim's device through email fraud or 0-day Trojans. Dangerous mail is very easy to identify – you will get it suddenly, with some files in it. If we talk about 0-day Trojans, it is a bit more complicated – you will not realize what it will be before you are taken over so that the most efficient method is to regularly download the newest updates for the system and other utilities, which you use.

Pulsar1 uses AES and RSA encryption algorithm, which are very diffucult to encrypt. It's computational complexity is high, so it's used by U.S. National Institute of Standards and Technology. There is no possibility to decrypt the files by simple bruteforce. We only can wait for decryptor or use special recovery program. Of course, you need to do it after virus full deletion. Follow to the next section to see practical advices.

Common ransomware programs are not overly complex in their code, though even the simplest one is extremely efficient. It is all about the encryption algorithms. Malicious programs' task is not to take the files. All it needs to do is to penetrate the computer, encode your information and remove the real data, placing the encrypted files instead of them. The information are useless when they are encoded. You cannot use them and cannot bring them to norm. When the job is finished, ransomware gives you a ransom message, and when it popped up – you know that the data are corrupted. There's only one turn you can take now - to uninstall Pulsar1 from the device and attempt to restore the files. We've said “attempt” because the probability to achieve success without a decryption tool are ghostly.

Pulsar1 removal guide

It is important to remove all malware elements before you proceed since if they stay on your computer, they will go on encrypting any file that comes into the hard drive. You should know that every medium carrier you are sticking into the infected computer would be corrupted also. To evade this – remove ransomware via following our useful advice. Keep in mind that the deletion will not recover the data, and if you do this, you will not be able to pay money to fraudsters. We recommend doing that as each ransom gained makes swindlers more positive in their "business" and increases their funds to develop other viruses. Significant point is that when you are dealing with web-criminals, they can just receive your funds and forget about you. They have recently ciphered your data, and you, probably, don't want to send them some money after that.

Pulsar1 decryption instruction

The worst disaster which can meet you on the Web It's a clear robbery, only without real robbers close to you: web-criminals penetrate the system and grab everything they wish, casting a victim aside with a crippled hard drive, filled with wasted files. Pulsar1 virus is the brightest example of encrypting programs: it’s not hard to get and very hard to beat, but we can help you with it. On this page, we want to explain to you what is ransomware and the ways of its penetration into your computer. We'll tell you what measures you should take to avoid ransomware infestation, and what you should do to decrypt your files. Remember that most of the ransomware won't ever get beaten, and if you have one – your information might be already gone forever. Sometimes web-criminals make an error to create the approach to neutralize their virus or to reverse its actions.

When you uninstall Pulsar1 from the machine, and you double-checked it, you have to consider the decryption methods. On the first place, we have to mention that the very efficient manner is to load a backup. If you have the backups of your files and Pulsar1 is entirely removed – don't bother. Erase the spoiled information and upload the copies. If there were no previously saved copies – the chances to recover the data are way lower. The single method to recover them is the Shadow Volume Copies. We're saying about the basic tool of the Windows OS, and it saves each file that was modified. You can access them with the help of specific recovery programs.

Naturally, the complex viruses can remove these files, but if you use an entry that has no administrator rights, the virus just couldn’t do that without your permit. You may recall that sometime before you've seen a hacker's message you've seen another menu, asking to apply changes to the system. If you have cancelled these changes – your SVC are still there waiting for you, so you might access them and restore the files with the help of such programs as Recuva or ShadowExplorer. They may be found in the Net. You might download them from the websites of their developers, with detailed instructions. In case you want more information about this – you might look at this entry on information restoration: article about files decryption.
