Virus Bulletin Board: For the latest Emergency related news and notices
Around the period of the Year 2000 transition it is expected that computer viruses will be spread by people seeking to
destabilize the Internet.
Nov. 11, 1999
Patch Available for "scriptlet.typelib/Eyedog" Vulnerability
Microsoft has released a patch that eliminates security vulnerabilities
in two ActiveX controls. The net effect of the vulnerabilities is that
a web page could take unauthorized action against a person who visited
it. Specifically, the web page would be able to do anything on the computer
that the user could do.
Frequently asked questions regarding this vulnerability
Once the virus is triggered the first 2048 sectors of each hard drive
in the computer are overwritten with random data. This area of the hard
drive contains important information about the files on the computer. Without
this file information the computer will think the hard drive is empty.
The virus will also write one byte of data to the BIOS boot block which
is critical for booting a computer. Writing to the system BIOS can be prevented
by setting a jumper on most motherboards. Contact the computer vendor or
motherboard vendor for assistance with their product. If the virus succeeds
in reprogramming the flash BIOS ROM, there is no software remedy for it:
your PC will no longer be bootable and the flash BIOS will need to be replaced
or re-programmed in a special EEPROM programming device. Where the flash
BIOS ROM is permanently attached to the motherboard, the entire motherboard
will need replacing. The damage caused to the information on the hard disk
is possibly recoverable by using data recovery services, and the success
depends on the disk size, format, fragmentation etc.
