Brief Description 

    

Radoppan.F is a virus that spreads to other computers by copying its code to other files or programs.

 

  • In the local network: it generates a large amount of network activity and consumes bandwidth.

 

It reduces the security level of the computer: it changes the security settings of Internet Explorer, decreasing its security level.

 

Radoppan.F accesses several websites to download files, which it then runs. These can be any type of file, although they are normally malware.

 

It uses stealth techniques to avoid being detected by the user:

  • It uses techniques included in its code to hide itself while it is active.
  • It injects itself in running processes.

 

It uses several methods in order to avoid detection by antivirus companies:

  • It prevents scanning tools from running, such as Windows Registry Editor, FileMonitor, etc.

 

Radoppan.F uses the following propagation or distribution methods:

  • Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
  • Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
  • File infection: it infects different types of files, which are then distributed through any of the usual means: floppy disks, email messages with attachments, Internet download, files transferred via FTP, IRC channels, P2P file sharing networks, etc.

 

Radoppan.F uses the following infection strategies:

  • Resident: once it has been run, the virus goes memory resident and stops functions belonging to the operating system. Therefore, every time the operating system or an application tries to access any of these functions, the virus will activate and infect new files.
  • Prepending: it enters its code at the beginning of the file it infects. By doing this, it ensures that the virus is run every time the infected file is executed, but without interfering the functioning of the file.
