Technical Details



Variant:Staple.A

This worm arrives in a email message with the following content:

  Subject:    RE:Injustice     Body:       Dear      Did you send the attached message, I was not expecting this from you !     Attachment: injustice.TXT.vbs  

When executed, the worm copies itself to the Windows System directory as "injustice.TXT.vbs". Then it sends itself to 50 random recipients from each address book. The worm also sends several infected messages to email addresses in Israel.Next the worm shows a message related to Middle-East war, as follows:

Subject:

RE:Injustice

 Body: DearDid you send the attached message, I was not expecting this from you !

 Attachment: injustice.TXT.vbs

Finally VBS/Staple.A opens six Internet Explorer browser windows, and connects to related web sites.
