On a related subject, many of my clients are worried about viruses
that target their specific operating environment. I am referring to
sophisticated entities here, such as banks and defense contractors,
that use computers for very important work involving millions of
dollars worth of transactions or life-and-death process control. It is
time we all acknowledged that in certain situations, viruses can cause
damage that is MUCH greater than the value of disk files. Prudent
businesses need to be concerned about "insider jobs" using viruses,
trojan horses, logic bombs, etc. that target them specifically. These
"inside jobs" may also target whatever defense mechanisms may be in
place. I have been referring to these attacks as "surgical strikes".
Perhaps a better term would be "targetted strikes". Although I am
aware of organizations that have purchased sophisticated defense
mechanisms to counter these kinds of attacks, I don't think knowledge
of the insider attacks will ever be as widespread as our knowledge of
more conventional viruses has become. This is because of the sensitive
nature of the attacks and damages done. The victims of these surgical
strikes handle them internally and secretly.
