Evaluation of files for cyber threats using a machine learning model
A system for evaluating files for cyber threats includes a machine learning model and a locality sensitive hash (LSH) repository. When the machine learning model classifies a target file as normal, the system searches the LSH repository for a malicious locality sensitive hash that is similar to a target locality sensitive hash of the target file. When the machine learning model classifies the target file as malicious, the system checks if response actions are enabled for the target file. The system reevaluates files that have been declared as normal, and updates the LSH repository in the event of false negatives. The system disables response actions for files that have been reported as false positives.
