Brief Description 

    

IRCBot.ADF is a worm that spreads by copying itself, without infecting other files.

 

It captures certain information entered or saved by the user, with the corresponding threat to privacy: passwords saved by certain Windows services; keystrokes, in order to obtain information for accessing online banking services, passwords and other confidential information.

It sends the gathered information to a remote user by any available means: email, FTP, etc.

 

It affects productivity, preventing tasks from being carried out:

  • In the affected computer: it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.

 

It reduces the security level of the computer: it awaits remote-control orders received through IRC; it changes system permissions, decreasing the security level.

 

IRCBot.ADF prevents access from programs to websites of several companies related with security tools (antivirus programs, firewalls, etc.).

 

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.
  • It terminates its own execution if it detects that a memory dump program is running, such as Procdump.

 

IRCBot.ADF 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.
  • IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
