So far we have seen so many machine learning (ML) papers in computer vision, from object detections to activity recognitions. There have been tons of papers doing the good, and the same that many are doing the bad thing, namely adversarial ML. Many papers are now following the trend to attack existing well-trained ML models. One example is by wearing a glass with special colors designed, the guy can be recognized as someone else, by machines (shown as the figure below). You can find many many papers on this topic.
