; [ Win32.Seraph@mm Vorgon/iKX ]
; [ 28672 bytes Target - PE ]
; [ 09/28/03 Made in Canada ]
;
;
;
;
; [ Introduction ]
;
; Seraph is a mass-mailing virus that takes advantage of social engineering. This may sound
; boring to you, but it takes social engineering to the next level. Seraph is an information
; gatherer. It takes data from websites, computers, URL's and uses what it finds to generate
; a convincing and personal email message.
;
; So what information does Seraph gather? Seraph gathers information about the Internet service
; provider of the computers it infects. Information such as:
;
; ISP Name example: AOL
; Domain example: AOL.COM
; Website example: WWW.AOL.COM
; Logo example: HTTP://www.aol.com/logo.gif
; Deadline example: SEPTEMBER 21, 2003
; Copyright String example: (C) 2003 AOL INC.
;
; What does Seraph do with this information? Seraph takes everything you see above and generates
; an email message in HTML format. The message containing a logo image, names, valid email
; addresses, etc, appears to be a security update from your ISP. Unsuspecting victims reading this
; email message see that they must install the attached update by the deadline date, or face
; disconnection of there Internet service.
;
; How does Seraph know the email addresses of other people on the same ISP? Seraph takes a list
; of the 1024 most popular surnames in the USA and randomly selects one. It then a appends a first
; initial either the start or the end of the surname. This gives a possible 53238 email addresses
; per ISP.
;
; Sure this will spread to users on the same ISP, but how does it spread to other ISP's? Seraph
; is highly infectious. Every time it runs it infects 50 files on all drives it can find on a
; computer, except CD-ROM and drive A. It will naturally find executables in file sharing
; directories, shared folders, and anything else you can imagine.
;
;
; [ Other ]
;
; I named this virus after Seraph from the Matrix Reloaded. Seraph (the Chinese guy Neo meets
; before meeting the Oracle) had golden code and was so spectacular because he came from the first
; incarnation of the matrix, which was heaven. "Seraph" is singular for the plural "seraphim". The
; seraphim are the highest choir of angels and included amongst others: Lucifer, Gabriele, Raziel
; and Malaciah, and they sit on the 8th level of Heaven just one below God.
;
;
; [ Bug Fixes ]
;
; Below are a list of bugs i have fixed in this version.
;
; -The find file code begins searching at the start of the first drive instead of the current
; Directory. This bug was causing the entire contents of the most important drive to be excluded
; from the search.
;
; -Files in the system directory are no longer infected. Infecting files in this directory was
; causing Windows to not boot at all.
;
; -The program to be run on start-up is no longer whatever infected program is executed. It has
; been changed to the program that was last infected. Before if the user deleted the infected
; email attachment after executing the virus it would not be able to run on start-up.
;
;
; [ The Infection ]
;
; Below is a break down of what the virus does in order:
;
; - Decrypt the virus
; - Get the address of GetModuleHandleA
; - Get the kernel32.dll address
; - Get the address of GetProcAddress
; - Load the win9x API functions
; - Create a thread to execute the rest of the virus code
; - Infect 50 files on drives B-Z, excluding CD-ROM
; - Make the last file infected run on start-up
; - Display an install message if the filename is patch110.exe
; - On February 23 display the pay load
; - Load the win2k API functions if the OS version permits
; - Get the IP address of the computer
; - Get the hostname of the computer
; - Extract the ISP domain from the host name of the computer
; - Download the main page of the internet service provider and handle redirections
; - Search the webpage for a logo image URL
; - Get the company name of the ISP
; - Create a dead line date for the email message
; - Generate an email address
; - Create the email message using all the data collected
; - Send the email message
; - Send the current host EXE as the update attachment.
; - Exit the thread
