Welcome to the Virus Encyclopedia of Panda Security.
It allows to gain remote access to the affected computer. It spreads and affects other computers.

|Yes, using TruPrevent Technologies
|VB.SX is a worm with that has backdoor characteristics. VB.SX spreads by copying itself, without infecting other files. Its main objective is to collapse computers and networks, thus preventing users from working on their computers.|
Furthermore, due to its backdoor characteristics, VB.SX allows hackers to gain remote access to the affected computer. Therefore, hackers will be able to carry out actions that compromise user confidentiality and impede the tasks carried out on the computer.
It captures certain information entered or saved by the user, with the corresponding threat to privacy:
It affects productivity, preventing tasks from being carried out:
- In the affected computer:
causes system slowdowns.
- 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.
It uses stealth techniques to avoid being detected by the user:
- It modifies system permissions in order to hide itself.
It uses several methods in order to avoid detection by antivirus companies:
- It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
VB.SX 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.
