OSIRIS-9b28.html is a malicious file that appears on the computer after the Osiris ransomware virus secretly infiltrates the system and encrypts the existing files. Osiris is one of the latest versions of the infamous Locky virus which is this year’s most dreaded cyber threat. Apart from Osiris, Locky creators have released a bunch of other ancient mythology-based virus versions including Odin, Thor, or Aesir. All of these viruses share a similar structure and behavioral patterns on the infected computers. After stealthily infiltrating the system, they start scanning it for certain file types and, upon detection, use sophisticated ciphers to encode them. The next step is ransom note delivery. These files containing data recovery instructions may replace the infected computer’s desktop picture or be displayed on a lock screen, obstructing the access of any system features entirely. Nevertheless, most commonly, the note is simply delivered through automatically generated .txt or .html files. In the case of Osiris infiltration, it's the already mentioned OSIRIS-9b28.html document.
OSIRIS-9b28.html features a link to a malicious web page which provides links to Wikipedia articles, helping the ransomware victim to comprehend what encryption is and how it affects the files. Also, the extortionists explain that the lost data can only be retrieved by purchasing a private decryption key for 0.5 to 4 Bitcoin. Don’t ever collaborate with virus developers in any way, especially if it involves financial matters. Remove OSIRIS-9b28.html along with the rest of the virus files from your computer using Reimage or similar anti-malware software.
OSIRIS-9b28.html file never travels alone. It is placed on the computer after the malicious Osiris script initiates its download. Thus, to avoid its appearance on the computer, the primary importance should be dedicated to system’s protection against ransomware. For this purpose, it is recommended to obtain reputable virus-fighting tools and pay more attention to the content we are downloading and installing on our computers. Unfortunately, OSIRIS-9b28.html file may appear on the computers of the most cautious users. Thus, we strongly suggest keeping data backups for that extra layer of security.
As already pointed out previously, OSIRIS-9b28.html file is only one part of the virus and does not actually initiate any malicious activities on the infected computer itself. Nevertheless, if this file remains on the computer after the virus elimination, the consequences are highly unpredictable. Thus, when eliminating the Osiris ransomware, you should don’t forget to remove OSIRIS-9b28.html as well. Nevertheless, if you trust some antivirus utilities with the system cleanup, OSIRIS-9b28.html removal will be carried out automatically.
