Binary classification aims to separate elements of a given dataset into two groups on the basis of some learned classification rule. It has extensive applications from security analytics, fraud detection, malware identification, and much more. Being a supervised machine learning method, binary classification relies on the presence of labeled training data that can be used as examples from which a model can learn what separates the classes.

Ransomware is a serious threat to institutions of all kinds, resulting in mounting costs for organizations that must literally pay ransom to regain access to their essential systems. A ransomware attack takes place when a cybercriminal denies an organization access to the data it needs to conduct business, usually by encrypting the data with a secret key. The attacker then offers to reveal the encryption key in exchange for a payment. The payment can vary in amount or kind.
