ConMan 1995 Link Virus
------------------------
ConMan 1995 Linkvirus:
Other possible names: M-Hac Virus, Bloody Virus
Detected in: M-hac.lha and Bloody.EXE
Detected when: August 1995/Germany SOS
Linking method: 4eb9 (!!!!)
Resident: NO
Length: 1836 bytes
This is a new type of linkvirus. There are 2 installers known yet.
It simply creates a new process with the known CONMAN code , but
now with different names.
Possible names are:
C:DIR
ramlib
Background_Process
RAm
L:FastFileSystem
LIBS: gadtools.library
Workbench
DF0
addbuffers
CON
LIB:req.library
CLI(0): no command loaded
CLI(1): no command loaded
Please note that several of this takss can appear in normal systems,
too.
The speciality of this virus is, that it uses a intern 4eb9 linker
to link to files. Quite tricky. Viruskillers like VT, VZ_II and
VW should so be able to detect the infected files.
The linking routine knows the following hunksymbols: $3f2,$3f3,$3ec
and $3eb. The code is a little bit dangerous, but I will implent
in VirusWorkshop a complete reverse analyzed routine, so it should
be no problem to repair even not working infected files.
The virus adds 4 hunks to the file and the linked code is partly
packed. It is packed with StoneCracker 4.04ß and then afterwards
manipulated.
The virus is not memory resident.
