摘要： In one embodiment, a method includes identifying, using one or more processors, a plurality of characteristics of a Portable Document Format (PDF) file. The method also includes determining, using the one or more processors, for each of the plurality of characteristics, a score corresponding to the characteristic. In addition, the method includes comparing, using the one or more processors, the determined scores to a first threshold. Based at least on the comparison of the determined scores to the first threshold, the method includes determining, using the one or more processors, that the PDF file is potential malware.

摘要： A computer-implemented method includes accessing, by an analysis console, information related to a first file received at a first host of a plurality of hosts. Each host is capable of running a corresponding set of malware detection processes. The information includes: an identifier of the first file; and data indicating a first result of the first host applying the set of malware detection processes to the first file. The identifier is generated by the first host and is usable by each of the hosts to determine whether a second file comprises content substantially equivalent to content of the first file. The analysis console generates a first output including: the identifier of the first file; and a second result indicating whether the first file comprises malware. The second result is usable by each of the hosts to determine whether the second file comprises malware. The first output is propagated to the hosts.

摘要： In accordance with particular embodiments, a method includes intercepting a communication and extracting metadata associated with the communication. The extracted metadata comprises a plurality of different fields from communication metadata and file metadata. The method further includes determining a score, based on previous communications, for each field of the extracted metadata. The score is indicative of a likelihood that the communication is a malicious communication. The method additionally includes combining the scores to generate a combined score for the communication based on an algorithm developed from the previous communications. The method also includes generating, based on the combined score at a first time, a predicted classification as to whether the communication is a malicious communication. The method further includes receiving, at a second time subsequent to the first time, an indication of whether the communication is a malicious communication and updating the algorithm based on the indication.

摘要： In certain embodiments, a method includes receiving, at a first malware detection node, from a malware detection system a request to apply a first malware detection technique to a file. The malware detection system is configured to determine whether the file is suspected malware by analyzing a plurality of predefined result states received in response to the first malware detection node applying the first malware detection technique to the file and a second malware detection node applying a second malware detection technique to the file. The method includes receiving at least one result from a malware detection engine of applying the first malware detection technique to the file and determining at least one predefined result state based on the received at least one result. The method includes reporting, by the first malware detection node, the at least one predefined result state to the malware detection system.
