In general, in one aspect, a method for machine learning recognition of portable executable files as malware includes providing training data comprising features of portable executable files and descriptive information for the portable executable files, the descriptive information comprising a family or type of malware. The method may include training a model using the training data to detect malware. The method may include using the trained model to recognize malware by providing features of a portable executable file as input and providing a threat score and descriptive information as output.

Attribute relevance tagging in malware recognition

A system for conducting a security recognition task, the system comprising a memory configured to store a model and training data including auxiliary information that will not be available as input to the model when the model is used as a security recognition task model for the security recognition task. The system further comprising one or more processors communicably linked to the memory and comprising a training unit and a prediction unit. The training unit is configured to receive the training data and the model from the memory and subsequently provide the training data to the model, and train the model, as the security recognition task model, using the training data to predict the auxiliary information as well as to perform the security recognition task, thereby improving performance of the security recognition task. The prediction unit is configured to use the security recognition task model output to perform the security recognition task while ignoring the auxiliary attributes in the model output.
