This contest is for a prior art search. We are ideally looking for a reference that describes a process for assessing whether an executable file is harmful by analyzing metadata and other characteristics of the file that can be determined without unpacking or executing it. Metadata could be file size, copyright information, creation date, etc. This process involves generating a feature vector from these characteristics, and potentially turning certain features on or off based on whether the metadata or characteristics fall within predefined ranges. The generated feature vector is then processed using a support vector machine to assess the file's risk of harm. The reference should also mention the possibility of determining if the file is known to be malicious, benign, or unwanted. The file size may be used to determine whether certain features in the feature vector are turned on or off, and the reference may define either a minimum size for harmful files or a maximum size for benign files.
