;PHOEBE
|
|
;coded by Opic of the Codebreakers
|
|
;PHOEBE is an appending .com infector with DT via a dotdot routine
|
|
;infection criteria is met on a moday once all files that are capable of
|
|
;being infected by PHOEBE are, a payload is delivered:
|
|
;the monitor will print a message to the screen(in the French) which
|
|
;translates to;"Indroducing PHOEBE, she was coded in the heart of midwest
|
|
;america in the autumn of ninteen ninty-seven by Opic of The Codebreakers"
|
|
;along with a text string which will be printed to the printer. Thanx go
|
|
;out to:Spo0ky,Arsonic,and Sea4 for which without their help Phoebe whould
|
|
;not be what she is today. PHOEBE can be assembled using a86 V4.02
|
|
;it should be noted that phoebe has no anti-av routines, yet is still
|
|
;remains undetectable by most av software. a testament to the inconsistancy
|
|
;of many av scanners, specifically windows95 scanners.
