Researchers have successfully proven that viruses can be weaponized to infect computers and take them over. And if that’s not the premise of a dystopian sci-fi novel, I don’t know what is.
The University of Washington recently baked malware into a genetic molecule and then infected a system analyzing it. If it sounds like DNA data storage, you’re right; the premise is a natural expansion.
If you can put good code on DNA, then naturally you can put bad code on it – and any system that reads it is going to be at risk of infection. Which begs the question – since scientists have just learned to store data on atoms, will there one day be atomic-level malware?
