You thought your machine were well protected, didn't you? Deep in your big fancy buildings with secured access for only a few trusted employees - a virtual fortress, only ever violated by the emails you decide to reply to. Otherwise unassailable, no?
Maybe you shouldn't have accepted samples from my lab. Do you think it's coincidence that machines in two MDPCs in two different countries have gone down while processing our samples in the last month? Do you? Maybe it's worth considering the possibility that what at first seemed like an innocent sample delivered to your door was actually anything but. Once you let it in the door, placed it on your machine and left it alone to run, it was all over. While your technicians slept soundly, our samples were working away. Be afraid, your machines are no longer safe.
