New machine learning model sifts through the good to unearth the bad in evasive malware

Most machine learning models are trained on a mix of malicious and clean features. Attackers routinely try to throw these models off balance by stuffing clean features into malware. Monotonic models are resistant against adversarial attacks because they are trained differently: they only look for malicious features. The magic is this: Attackers can’t evade a monotonic model by adding clean features. To evade a monotonic model, an attacker would have to remove malicious features.

Artificial intelligence and machine learning are persistently in the headlines with rich debate over its next advances. Will cybercriminals further leverage machine learning to craft attacks? Can defenders build a machine learning model capable of detecting all malware? We believe machine learning is an essential and critical piece of cybersecurity, but it must be only [&#8230;]<img src=”http://feeds.feedburner.com/~r/sophos/dgdY/~4/z8gcd4bDkho” height=”1″ width=”1″ alt=””/>
