Brief Description 

    

Downloader.LLH is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.

 

  • 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.

 

Downloader.LLH 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 injects itself in running processes.

 

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.

 

Downloader.LLH 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.
