Classifying Sequences of Extreme Length with Constant Memory Applied to Malware Detection

1 code implementation17 Dec 2020 Edward Raff, William Fleshman, Richard Zak, Hyrum S. Anderson, Bobby Filar, Mark McLean

Recent works within machine learning have been tackling inputs of ever-increasing size, with cybersecurity presenting sequence classification problems of particularly extreme lengths.

Getting Passive Aggressive About False Positives: Patching Deployed Malware Detectors

no code implementations22 Oct 2020 Edward Raff, Bobby Filar, James Holt

We propose a strategy for fixing false positives in production after a model has already been deployed.

Learning to Evade Static PE Machine Learning Malware Models via Reinforcement Learning

4 code implementations arXiv 2018 Hyrum S. Anderson, Anant Kharkar, Bobby Filar, David Evans, Phil Roth

We show in experiments that our method can attack a gradient-boosted machine learning model with evasion rates that are substantial and appear to be strongly dependent on the dataset.

DeepDGA: Adversarially-Tuned Domain Generation and Detection

no code implementations6 Oct 2016 Hyrum S. Anderson, Jonathan Woodbridge, Bobby Filar

We test the hypothesis of whether adversarially generated domains may be used to augment training sets in order to harden other machine learning models against yet-to-be-observed DGAs.
