“With the kind of virus called a time bomb during the ‘90s. It’s easy for crackers to write viruses that are activated at a particular later time.”

Is there any information on the damage any of these alleged 1990s time bomb virus’ caused when they were activated?

I only recall news of small damage caused to private computer systems and networks, because I had a pulse during the '90s and probably have near average long term memory. It's likely that some of the news of recent years involved time-activated viruses. An Internet search should yield some instances of time-activated viruses and damages caused by them. It seems there was news of DoS attacks done that way.
