  Neural networks are now actively being used for computer vision tasks in
security critical areas such as robotics, face recognition, autonomous vehicles
yet their safety is under question after the discovery of adversarial attacks.
In this paper we develop simplified adversarial attack algorithms based on a
scoping idea, which enables execution of fast adversarial attacks that minimize
structural image quality (SSIM) loss, allows performing efficient transfer
attacks with low target inference network call count and opens a possibility of
an attack using pen-only drawings on a paper for the MNIST handwritten digit
dataset. The presented adversarial attack analysis and the idea of attack
scoping can be easily expanded to different datasets, thus making the paper's
results applicable to a wide range of practical tasks.
