Problem

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.

Questions

#QuestionValue
1Is the reference either a U.S. Patent filed, a foreign patent published, or a non-patent document published or otherwise publicly available before June 2015? T/F
2Does the reference describe assessing whether an executable file is harmful (e.g., detecting malware) based on metadata or other characteristics of the file that are ascertainable without unpacking or executing the file (e.g., file size, copyright information, creation date, entropy, etc.)? 10
3Does the reference describe generating a feature vector from the metadata or other file characteristics? 10
4Are any features in the feature vector turned on or off based on whether the metadata or other file characteristics fall with a predefined range (e.g., (1) below a specific value, (2) between two specific values or (3) above a specific value)? 15
5Is a support vector machine used to process the generated feature vector to assess the file’s risk of harm? 10
6Does the reference describe determining if the file is known malicious, known benign, and/or known unwanted? 10
7Is file size used to determine whether any features in the feature vector are turned on or off? 20
8Does the reference define (1) a minimum size for harmful files so any file smaller than that is defined as safe/benign or (2) a file size above which files are assumed to be safe/benign? 25
