From a linked article:
In 2014 the security firm FireEye had issued warnings about a team of hackers that was planting BlackEnergy malware on targets that included Polish energy firms and Ukrainian government agencies; the group seemed to be developing methods to target the specialized computer architectures that are used for remotely managing physical industrial equipment. The group’s name came from references to Dune found buried in its code, terms like Harkonnen and Arrakis, an arid planet in the novel where massive sandworms roam the deserts.
No one knew much about the group’s intentions. But all signs indicated that the hackers were Russian: FireEye had traced one of Sandworm’s distinctive intrusion techniques to a presentation at a Russian hacker conference. And when FireEye’s engineers managed to access one of Sandworm’s unsecured command-and-control servers, they found instructions for how to use BlackEnergy written in Russian, along with other Russian-language files.
For some reason I find this single tidbit, that the Russians responsible for these attacks are (probably) into Dune, incredibly humanizing. I'm not entirely sure what to do with that.
