Abstract

See full text

Provided herein are systems and methods for targeted attack protection using predictive sandboxing. In exemplary embodiments, a method includes retrieving a Uniform Resource Locator (URL) from a message of a user and performing a preliminary determination to see if the URL can be discarded if it is not a candidate for sandboxing. The exemplary method includes computing a plurality of selection criteria factors for the URL if the URL passes the preliminary determination, each selection criteria factor having a respective factor threshold. The method can further include determining if any of the selection criteria factors for the URL exceeds the respective factor threshold for the respective selection criteria factor. Based on the determining, if any of the selection criteria factors exceeds the factor threshold for the selection criteria factor, the exemplary method includes automatically placing the URL in a sandbox for analysis.
