Adversarial example images appear to be of one class (e.g. dog or car), but are classified by machine learning image recognition systems as a class of the attacker's choosing. This talk covers a conceptual introduction to image recognition via convolutional neural networks, creating adversarial examples, and how the speaker adapted such an attack as a problem in picoCTF 2018, an introductory level capture the flag. The talk concludes with an overview of the current state of adversarial example generation in academia, including the current capabilities of defenses, and how attacks have been adapted for the real world. Prior conceptual knowledge of neural networks is not required.
