"It's really simple. There are always thousands of unused gates in every IC. Banks and banks of memory for the taking. Homosoto was no slouch, and he recognized that hardware viruses are the ultimate in underground computer warfare. Even better than the original Trojan Horse. No messy software to worry about, and extensive collateral damage to nearby electronic components. Makes repairs terrifically expensive."
Which chips are to be considered suspect? The Spook was clear.
"Any RAM or ROM chips with the OSO logo and a date code after 1/89 are potentially dangerous. They should be swapped out immediately for new, uninfected components. Also, OSO sold their chips, in die form, to other manufacturers to put their own names on them. I wish I knew to whom, but Homosoto's firm handled all of that."
The Spook also said to beware of any electronic device using OSO labeled or OSO made LS logic chips. Hundreds of millions of the LS logic chips, the so called Glue of electronics, are sold every year. In the electronics world they are considered 'dime-store' parts, selling for a few pennies each. However, in most elec- tronic systems, an inexpensive component failure is just as bad as an expensive component failure. In either case, it stops working.
The Spook continues: "The idea was to build a small timebomb into VCR's, televisions and radios. Not only computers, but alarm systems, cash registers, video games, blowing up all at once. At times it got very funny. Imagine dishwashers spitting up gallons of suds in kitchens everywhere. The ovens will be cook- ing pork tartar and toast a la burnt. What happens when Betty- Jean doesn't trust her appliances any more? The return line at Sears will be a week long."
I asked the Spook how this was possible? How could he inflict such damage without anyone noticing? His answer is as indicting as is his guilt. "No one checks. If the chip passes a few simple tests, it's put into a calculator or a clock or a tele- phone or an airplane. No one expects the chip to be hiding something destructive, so no one looks for it. Not even the military check. They just expect their chips to work in the frozen depths of space and survive a nuclear blast. They don't expect a virus to be lurking."
No matter what one thinks of the nameless, faceless person who hides behind the anonymity of these computerized confessions, one has to agree that the man known as the Spook has awakened this world to many of the dangers that unbridled technical proficiency brings. Have we taken too much liberty without the concomitant responsibility? I know that I find I wish I could run parts of my life in fast forward. Sitting in a movie theater, I feel myself tense as I realize I cannot speed up the slow parts. Has the infinite flexibility we have given ourselves outpaced social conscience?
Ironically, conversations with the Spook tended to be impersonal; not machine-like, but devoid of concern for people. I asked him if he cared.
"That was not the idea, as far as I know. In a way this was electronic warfare, in the true sense of the word. Collateral damage is unavoidable."
Hardware viruses in addition to software viruses. Is nothing sacred?
