Abstract
A scanning system for scanning computer files for exploits uses a database of validation rules, in respect of each of a plurality of file formats comprising data fields having a predetermined structure, the validation rules specifying valid structure and/or content for the data fields of the respective file format. Files are analysed to determine their file format. A validation process is performed comprising parsing the file to determine the structure and content of its data fields and validating the structure and/or content of the data fields of the file against the validation rules stored in the database in respect of the determined file format of the file. A file is determined to contain an exploit in response to the structure and/or content of the data fields of the file failing to be validated.
