COMMAND
Full Armor
SYSTEMS AFFECTED
Win95, NT (if running this program)
PROBLEM
Kimmie Dicaire found following. This is an alert for Full Armor
made by Micah Software and rated very high in PC Week. The
software itself is a desktop protection software that has many
many more options than the regular poledit that comes with Win95,
although it does utilize and expand on the poledit program. The
problem/hack comes into play when you get the Full Armor warning
that you don't have rights (or any other Full Armor dialog box) if
instead of just clicking the ok button to remove the dialog box,
instead you choose <ctrl> + <alt> + <del> to get to the task
manager you can end task on Full Armor and remove all the
protected areas, thus having full access to everything on your
destop/PC.
As anyone who runs '95 will tell you, when you turn it back on
scandisk comes up as well...it is possible to ctrl-break out of
scandisk and thus get an unprotected dos prompt, from there you
can modify whatever files you want, including full armors and
effectively disable its protection.
'chameleon' added following. Below is basically how to bypass
most "secure" desktop programs:
- turn on your computer. (Tuff one there)
- there will be a two or so second gap between seeing your windows
desktop and seeing the explorer bar across the bottom.
- during that two second gap, hit control + alt + delete... this
will load task manager.
- you now have taskmanager which will enable you to run whatever
you like. You also are able to do this without any restrictions
because you froze windows from loading explorer and Full Armor,
Fool Proof, Fortres 101 etc...
BTW, if you hit Ctrl-Esc at the Windows 95 login prompt, you'll
launch the task manager as well. From there, you can start the
Explorer, and you'll have full access to the computer. Windows 95
is inherently insecure.
The has been tested on both 486 and Pentium machine's all running
Win95 and the hack is reproduced everytime.
SOLUTION
There is no current work around for this hack. People at Micah
are currently re-working the code that should have a fix for
this by 6-9 or 10-1998. If you are running Full Armor it is
recommended that you get this fix when it becomes available.
Until then, to prevent this add the following to MSDOS.SYS under
the [Options] section:
BootSafe=0
BootKeys=0
BootWarn=0
AutoScan=0
Network=1 (if you have networking enabled)
While this does tend to stop most of the general populace from
bypassing the restrictions in effect - it still doesnt stop
someone booting off a disk, you could use a bios setting to boot
from C before A (if your bios supports it), hence bypassing this
as well. Stopping load of taskman.exe is to simply remove
taskman.exe from the machine. Another trick was to use the
keyboard remapper from the MS KernelToys to remap one of those
pesky CTRL, ALT or DEL keys.
