Osiris is a file encrypting malicious software, which will encrypt all your personal documents using RSA-2048 key (AES CBC 256-bit encryption algorithm), appending the .Osiris extension to encrypted files and renaming them as follows [8_random_characters]-[4_random_characters]-[4_random_characters]-[4_random_characters]-[12_random_characters].Osiris. The Osiris ransomware will then display a message which offer to decrypt the data if a payment is made via Bitcoins. If the payment is not made within 96 hours the ransom will double. Unfortunately, your computer is infected with the Locky ransowmare. The main goal of ransomware is to scare you into giving your money to the cybercriminals created this malware. Please, have in mind that there is absolutely no guarantee that by paying them they will remove the virus and release the hostage computer. You also will support the attackers by paying them back. This will only not only motivate them into attacking more people, but creating even more sophisticated and hard to remove ransomware viruses.

How did I get infected?

The Osiris virus file encryption is currently distributed via spam emails. Osiris is classified as a ransomware infection and as such what it does is to encrypt all the files on your PC. This means that you will not be able to open your photos, videos, or text documents if Osiris has gained access to your system. Shortly after infiltration, Osiris will present you with a message informing you about the encryption of your files and asking you to pay a ransom in order to get them back. No matter how worried you are and how important the encrypted files are, you should not spend the requested amount money because we can assure you that it will be useless. Instead, you should do your best to get rid on the malicious ransomware infection and start using your PC as you usually do.

This is how the ransom note will look like:

How is Osiris Distributed?

Same as other infections, ransomware is distributed in several ways. The most common one is by attaching the infection to a spam email and disguising the email as a real and urgent message. Then, when the user opens it and downloads the attached file, he or she automatically installs the malicious infection. Researches show, however, that Osiris mainly takes advantage of the vulnerabilities of the Adobe Flash player. If this program is not kept up-to-date, it creates opportunities for cyber criminals to exploit it and make you a subject to infections by Osiris. Also, if there is no active legitimate security tool to protect your system, it is very likely that you will soon end up with a bunch of infections on your PC, and pray that they are not ransomware like Osiris.

What is Osiris Virus?

There is a group of ransomware infections called LOCKY, and Osiris is the newest member of this group. Unfortunately unlike its predecessors Osiris will fully encrypt your files, so it will be practically impossible to decrypt them. Hence, you should not fall for the lies in the warning message that assures you that purchasing a special key or a code will restore your files. The only thing that can help you in this situation is file back-up, if you have done any prior to infecting your system with Osiris. Another problem that may occur concerns your privacy. Osiris will collect information about you that can be used for all kinds of purposes by the cyber criminals who created this ransomware. The moment you see a message by Osiris on your desktop, do not panic but immediately remove the infection from the PC.

What should I do?

The criminals are hoping that the surprise of loosing all your files will shock you and you will pay them the ransom. However this is not a good idea, for a couple of reasons.

  • Paying money to cyber criminals only encourages them to get better at their craft and extort even more people.
  • You are not guaranteed in any way that your files will be decrypted successfully if you make the payment.
  • There is absolutely no reason to pay until you’ve tried all the free methods first.
  • Antimalware and Antivirus companies are constantly developing their products to fight the bad guys

Attention! You should be aware that all of your accounts and passwords were likely compromised. Viruses are designed to collect every piece of private information. We advise you to change all your passwords, once you clean your computer, especially if you make online banking or shopping.
