Arsium Files Virus – Detailed Description
Arsium files viru is a dangerous new virus threat which was detected in a worldwide distribution campaign. At the moment it is known that it can be used as a platform to build other viruses on. This means that different hackers and groups can use it against their intended targets and deployed using the most popular spread strategies.
One of the most popular tactics is to create different phishing messages and sites that aim to impersonate well-known sites and services. By interacting with the shown contents the victim will infect themselves. In the case of email messages they can take the most popular forms such as password reset reminders, update notifications or special offers. They can link to a hacker-controlled site or inclue the virus installation code in links or attached files. The actual phishing sites are hosted on domain names that sound very similar to the landing pages of well-known companies and services. When the users enter in their addresses they may find copied contents from the real sites.
Another possibility that the hackers can use is the including of the underlying infection code in file carriers such as the following:
- Malicious Documents — The hackers can embed the necessary code as macros all popular document file formats: presentations, text documents, databases and spreadsheets. When opened by the victims they will be asked to enable them in order to correctly view the contents of the file. If done so the infection will be started.
- Application Setup Packages — The hackers can include the Arsium files virus code in application installers. Usually popular software which is often acquired by the end users: system utilities, creativity suites, productivity programs and even computer games.
Bear in mind that the browser hijackers are also a popular conduit for spreading the Arsium files virus. They are malicious extensions made compatible with the most popular web browsers. The plugins are uploaded to the relevant repositories of the browsers with fake user reviews and developer ID.

- Persistent Installation — The Arsium files virus can modify the boot options so that the virus threat is started every time the computer is powered on. In some cases it can also block access to the boot recovery options. This will make it very hard to follow the instructions in most manual user removal guides.
- Sensitive Data Removal — In certain situations the hackers can program the virus engines in order to locate and remove sensitive data which can make the computer much more difficult: backups, restore points and shadow volume copies.
In some cases the existing Arsium Files virus infections can be programmed into ediitng out existing Windows Registry values or creating new ones specific to the threat. Some of the most likely consequences ca lead to serious performance issues, the inability to launch certain services and unexpected errors.
The Arsium Files Virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.
You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.
