摘要
A system and method for .Net PE files malware detection is provided. The method may include accessing two or more portable executable (PE) files and detecting at least one identical global user identifier (GUID) attribute. In response to finding identical GUID attributes, the method may include clustering a group of files into family clusters each having the same GUID attribute. The method may generate and release a signature for the family cluster. An exoneration criteria level may be set in accordance with matching characteristics associated with an acceptable software standard for the computing system or network, such that when the exoneration criteria level is reached, the PE file is exonerated from being associated with PUA or malware. Until this criterion is met, the PE file will be identified as PUA or malware. Additional GUID attributes may be identified as further proof that the PE file is polymorphic.
