Cyberespionage groups or cybercriminals? UAV and C-UAV vendors and buyers are increasingly targeted.
#Resecurity had an interesting post on the topic.
As an example: about 1 GB of compressed #FortemTechnologies internal files wound up in the hands of an adversary, but Fortem denies there was any breach, claiming (wait for it):
" There was no breach. The files in question were attached to emails that had been shared outside of our network."
Shared intentionally with an adversary or cybercriminal? I tend to doubt that....
