  Robots applications in our daily life increase at an unprecedented pace. As
robots will soon operate "out in the wild", we must identify the safety and
security vulnerabilities they will face. Robotics researchers and manufacturers
focus their attention on new, cheaper, and more reliable applications. Still,
they often disregard the operability in adversarial environments where a
trusted or untrusted user can jeopardize or even alter the robot's task.
  In this paper, we identify a new paradigm of security threats in the next
generation of robots. These threats fall beyond the known hardware or
network-based ones, and we must find new solutions to address them. These new
threats include malicious use of the robot's privileged access, tampering with
the robot sensors system, and tricking the robot's deliberation into harmful
behaviors. We provide a taxonomy of attacks that exploit these vulnerabilities
with realistic examples, and we outline effective countermeasures to prevent
better, detect, and mitigate them.
