it affects Windows XP/2000 Pro/NT/Me/98/95 and spreads through the popular KaZaA application and through IRC

Panda Software, leading antivirus developer, has reported the appearance of Kazoa.C, alias Gool, a new worm/Trojan programmed in Delphi, which spreads through the popular file sharing application KaZaA and through the chat program IRC. It affects Windows XP/2000 Pro/NT/Me/98/95 and when installed on the affected computer, it changes entries in the Windows Registry in order to ensure that it is run every time Windows is started up. It also opens a port (usually 31337) and sends out the IP address of the affected computer via the Internet, leaving the computer vulnerable to remote attacks. An attacker would be able to carry out the following actions on the affected computer:
- Send messages
- Hide the Taskbar that appears on the desktop
- Delete the CMOS
- Provoke an error in the computer
- Use up memory
- Handle and send files
- Capture screens and keystrokes
- Obtain data on the operating system and characteristics of the machine.
Kazoa.C, alias Gool, modifies the default shared file folder in the application KaZaA and creates a large number of files, which contain the worm’s code, with names like Catherine Zeta Jones, Pamela Anderson, Sandra Bullock, Shakira or Pokemon. This worm tries to trick users into running these files by suggesting that they contain erotic photos, cracks for hacking operating systems etc. These files always have a double extension, but the real extension is .exe. If a computer is not configured to show all file extensions, these icons will be displayed as inoffensive jpg or .txt files. When the executable file is run (by double-clicking on the icon), Kazoa.C displays a screen.
If this malicious code detects that processes belonging to certain antivirus, security and system programs are active, it ends them.
