.OSIRIS File

What is the .OSIRIS file extension?

The .OSIRIS file extension is used by the OSIRIS ransomware to encrypt files on infected computers. OSIRIS ransomware is a type of malware that encrypts your files and demands a ransom payment in exchange for the decryption key. If you have files with the .OSIRIS file extension, it means that your computer has been infected with OSIRIS ransomware and your files have been encrypted.

OSIRIS ransomware is a variant of the Locky ransomware family. It was first discovered in December 2015 and has since infected millions of computers around the world. OSIRIS ransomware is typically spread through phishing emails and malicious attachments, but it can also be spread through exploit kits and malicious websites. Once OSIRIS ransomware has infected a computer, it will encrypt all of the files on the computer, including system files and personal documents, photos, videos, and music files.

Once the files have been encrypted, the ransomware will display a ransom note on the computer's desktop. The ransom note will contain instructions on how to pay the ransom to decrypt the files. The ransomware typically demands a ransom payment in Bitcoin.

There is no known way to decrypt .OSIRIS files without paying the ransom. However, there are some things you can do to protect yourself from OSIRIS ransomware infection, such as:

• Keep your software up to date. OSIRIS ransomware often exploits vulnerabilities in outdated software. By keeping your software up to date, you can help to protect yourself from infection.
• Use a strong antivirus program. A good antivirus program can help to detect and remove OSIRIS ransomware before it can encrypt your files.
• Be careful about what attachments you open. OSIRIS ransomware is often spread through malicious email attachments. Be careful about what email attachments you open, especially if they come from unknown senders.

If you think your computer has been infected with OSIRIS ransomware, you should immediately disconnect it from the internet and take steps to remove the infection. There are a number of free and paid ransomware removal tools available online. You can also contact a cybersecurity expert for assistance.
