Brief Description 

    

IRCbot.ADR 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 reduces the security level of the computer: it terminates processes belonging to security tools, such as antivirus programs and firewalls, leaving the computer defenseless against attacks from other malware; it awaits remote-control orders received through IRC; it changes system permissions, decreasing the security level.

 

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

 

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 terminates processes corresponding to several security tools, such as antivirus programs and firewalls, to prevent detection.
  • It deletes the original file from which it was run once it is installed on the computer.
  • It modifies system permissions in order to hide itself.

 

IRCbot.ADR 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.
