 The new type of logic bomb is turning physical.

A logic bomb is a computer virus that destroys databases or entire systems. Those computer viruses can be activated by data or by giving some stealth command to the targeted system. That command might be some kind of ALT+255 type order that activates the virus code. 

The traditional logic bombs can slip into the systems in the updates. In some scenarios, that malicious code would be masked as the GPS signal or delivered between GPS packages. 

Or those logic bombs can be hidden in components. If it is remotely-activated malware code in the kernel of the microchip, that thing can cause very bad things. It can format the microchip. And without that thing the microchip is useless. 

But there is the possibility that the malware or logic bomb turns physical. In extreme cases, logic bombs or malware code slips in the nuclear enrichment plant. Or even nuclear reactors. In enrichment plants, the malicious code can simply accelerate centrifuge too high speed. If the rod of the centrifuge is too long that thing can cause a nuclear explosion. Especially, if the centrifuge is handling plutonium. Like it does in nuclear weapon production. 

If the speed of the centrifuge is too low in nuclear weapon production. That thing causes that there is a too low count of plutonium and the nuclear weapon doesn't explode. The centrifuge is used as the separator for uranium ore. The malware can force to shut down the nuclear reactors but that kind of software can cause the china syndrome where the nucleus of the reactor is melting. 

But the malicious software can also cause problems for producing things like fuels or explosives. There is the possibility that in the production process of explosives in the process slips too much nitric acid. And that turns it too hard. Or the malicious software would disturb the relationships in chemicals that are used for fuel. 

The new type of logic bomb is targeted to disturb the manufacturing process of the 3D-based printing technology. Those logic bombs can also disturb all work that is made by using automatized assembly lines. If there is a discontinuity in welds. 

Or internal structure in the 3D-printed machine parts like turbine wings that thing can be destructive. There are many points in the physical part's production processes where the logic bombs can affect.
