The Pentagon virus consists of:
|
||
|
||
* a normal MS-DOS 3.20 boot sector where the name "IBM" has been
|
||
replaced by "HAL".
|
||
|
||
* A file with the name of the hex character 0F9H. This file contains the
|
||
portion of the virus code which would not fit into the boot sector, as
|
||
well as the original boot sector of the infected disk. This file is
|
||
addressed by its absolute address, rather than name.
|
||
|
||
* A file named PENTAGON.TXT that does not appear to be used or contain
|
||
any data. Portions of this virus are encrypted.
|
||
|
||
The Pentagon virus will look for and remove the Brain virus from any
|
||
disk that it infects. It is memory resident, occupying 5K of RAM, and can
|
||
survive a warm reboot.
