Fueled by access to ever-increasing computational power, the past few decades have seen an explosion in Artificial Intelligence (AI) capabilities and applications. Today, AI is used in everything from image and speech recognition, to recommendation systems, to biomedical informatics to self-driving cars. Recently, various cyber security vendors are adapting "AI Technologies" in their products in order to improve the detection rate of malware and attacks. In particular, AI is expected to slowly replace the old-style signature-based detection of malware. Signature-based detection has proved to be ineffective against today's "one-million-new-samples-per-day" malware variants. But what does it really mean to use AI in detection of attacks and malware; can it really live up to its promises?
