VBS.Stages.A - Worm/Virus
The worm is coded in Visual Basic Script (VBS) language. It spreads by e-mail messages triggered by its own code. The addresees of messages are selected from the address book (first one hundred addresses). The Subject field of the messages can vary. The following subjects are possible: "Life stages", "Funny" or "Jokes". Occasionally the word "text" is added to the aforementioned subject. The body of the message usually reads: "> The male and female stages of life." sometimes followed by a greeting: "Bye.". The worm itself is hidden in the message attachment named: LIFE_STAGES.TXT.SHS. After clicking at this attachment the notepad is open containing the following, somewhat funny content:
