Summary:A method for extracting the genetic fingerprinting of a malicious document file includes the steps of establishing a database to store a plurality of genetic fingerprinting data of the first malicious document, then retrieving a document file sent via the Internet, and then proceeding with multi-point detection and extraction to the document file, so as to obtain a multi-point section, then comparing and analyzing the multi-point section with the plurality of genetic fingerprinting data of the first malicious document to confirm whether the multi-point section program code of the document file matches a malicious feature, thereby achieves the goal of extracting the content information of the document file and converts it into the genetic fingerprinting data of a new malicious document.
