Protecting 3D printers from cyberattacks could be as simple as listening carefully

As 3D printers grow smarter and continue to embed themselves in manufacturing and product creation processes, they are exposed to online malefactors just like every other device and network. Security researchers suggest a way to prevent hackers from sabotaging the outputs of 3D printers: listen very, very carefully.

Now, you’re forgiven if someone hacking a 3D printer doesn’t strike you as a particularly egregious threat. But they really are starting to be used for more than hobby and prototyping purposes: prosthetics are one common use, and improved materials have made automotive and aerospace applications possible.

The problem, as some security researchers have already demonstrated, is that a hacker could take over the machine and not merely shut it down but introduce flaws…
