; This is the first collaboration of the russian virus writer Z0MBiE to 29A,
; and also his first Win95 PE infector. It is an encrypted runtime PE infec-
; tor which, after having decrypted its body, locates KERNEL32.DLL and then
; looks in its export table for the address of the API functions used it the
; viral code. This virus has also the feature which consists on looking for
; files to infect in the Windows directory as well as in other units. PE in-
; fection consists on adding a new section (called .Z0MBiE) to infected exe-
; cutables and creating an entry point in it for the virus code. Last but
; not least, Win95.Z0MBiE, after having infected files in a given drive, in-
; serts a dropper called ZSetUp.EXE in the root directory. This file is ac-
; tually a dropper of the Z0MBiE.1922 virus, also included in this issue of
; 29A, in the "Viruses" section of the magazine. Its peculiarities are des-
; cribed there, together with the analysis of Igor Daniloff, same as the one
; which follows, describing the behavior of Win95.ZOMBiE.

;
; Win95.Zombie is a nondestructive nonresident encrypted virus which
; infects PortableExecutable EXE files. On starting an infected file,
; the virus decryptor explodes the main virus body and passes control
; to it. The main virus body determines the location of KERNEL32 Export
; Table in memory and saves in its code the address of WIN32 KERNEL API
; functions that are essential for infecting files.
;
; Then the virus determines the command line of the currently-loaded
; infected program and loads it once again through the WinExec function.
; The second virus copy then infects the system. The first virus copy
; (that started a second copy the infected program), after completing
; the WinExec procedure, returns control to the host program.
;
; To infect PE EXE files, the virus scans the Windows system folder and
; also takes peeps into all other folders in drives C:, D:, E:, and F:.
; On detecting a PE EXE file, the virus analyzes the file. If all is well,
; the file is infected. Win95.Zombie creates a new segment section .Z0MBiE
; in the PE header, sets an entry point to it, and appends a copy of the
; encrypted code at the file end which is within the limits of the region
; of this segment section. After infecting the logical drive, the virus
; creates a dropper file ZSetUp.EXE in the root directory and assigns it
; ARCHIVE and SYSTEM attributes. In this file, Win95.Zombie plants a
; Zombie.1922 virus code. The virus contains a few text strings:
;
; Z0MBiE 1.01 (c) 1997
; My 2nd virii for mustdie
; Tnx to S.S.R.

; Z0MBiE`1668 v1.00 (c) 1997 Z0MBiE
