Well this is slightly different. DGA seems to actually use it as a rendez-vous host, whereas in this case, it literally is a dummy domain that they didn't even bother registering, with the only purpose of checking if they were in a VM. In which case, generating any long hash domain would most likely not be registered and would do the job.
