The attachment will be a random name with extensions .BMP.vbs, .JPG.vbs, .GIF.vbs ( Example: aEcOb.JPG.vbs ). The VBS extension will not appear if Windows Scripting Host is installed.

                     While opening the e-mail attachment, will copy LINUX32.vbs and a random file name in windows system folder and reload.vbs in windows folder. Then it changes the registry settings so that the the script is automatically executed when the system is restarted.

                     Then it checks for "WinFAT32.exe" in windows system folder, if found it also tries to download three files named macromedia32.zip, linux321.zip and linux322.zip. If the files are download , it copies the files in the name of important_note.txt, logow.sys, logos.sys Windows folder. Actaully, these are not zip files. The first one is a text file and other two are BMP files. The bmp file is used for windows startup and shutdown screen. The text file is displayed by modifying the registry.

                     Then the worm creates "US-PRESIDENT-AND-FBI-SECRETS.HTM" in windows system folder. It opens the Microsoft Outlook Address book and sends email to all the email ids stored in that. The message subject, body and attachment details will be the same as explained above.

                     Then the virus searches for all local and remote drives and overwrites .js, .jse, .css, .wsh, .sct and .hta files with the script. It overwrites jpg, jpeg files with the virus code and renames to .vbs extension. In case of mp2 and mp3 files it hides the original file and creates a new file with .vbs extension and writes its code there.

                     The worm contains date activated payload also. When the current date is 17th and current month is September ( 9th month ) it will display the following message.

"Dedicated to my best brother=> Christiam Julian(C.J.G.S.)"
