Abstract
Detection of malicious files is disclosed. A set comprising one or more sample classification models is stored on a networked device. N-gram analysis is performed on a sequence of received packets associated with a received file. Performing the n-gram analysis includes using at least one stored sample classification model. A determination is made that the received file is malicious based at least in part on the n-gram analysis of the sequence of received packets. In response to determining that the file is malicious, propagation of the received file is prevented.
