20130074185 | Providing a Network-Accessible Malware Analysis - In certain embodiments, a computer-implemented method comprises receiving, via a computer network and from a first computer system, a first malware analysis request. The first malware analysis request comprises a file to be analyzed for malware by a malware analysis system. The method includes initiating a malware analysis by the malware analysis system of the first file for malware. The method includes communicating to the first computer system a response for the first file determined by the malware analysis system to the first computer system. The response comprises an indication of whether the first file comprises malware. | 03-21-2013 |
20130081142 | System, Method, and Logic for Classifying Communications - 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. | 03-28-2013 |
