Abstract: A method of detecting leakage of sensitive source code on network-accessible sites is provided. The method includes determining a set of unique identifying elements that identify a sensitive source code module accessed from a source code repository; using a crawler server connected to an external network to automatically search a list of one or more network-accessible sites for text that matches one or more of the unique identifying elements in the set of unique identifying elements, to provide search results; collecting the search results in a memory of the crawler server; determining a relevancy for each of the search results based at least in part on a number of the unique identifying elements that were matched and on a number of search results; sorting the results according to the relevancy; and providing the results to a user, to indicate whether sensitive source code was found on the network-accessible sites.

Abstract: Embodiments of the invention provide a method and a system of detecting source code in a message being sent over a digital communication network to secure against unauthorized leakage of source code. The message is intercepted on a network device, placed into a memory on the network device, and divided into one or more segments, wherein each segment includes a predetermined number of lines of text from the message. For each segment, one or more syntax rules of a programming language is applied to the segment and a predetermined number of context lines of text before the segment and/or after the segment, to determine which of the syntax rules of the programming language are matched in the segment. A determination of whether the text message includes source code is provided based on the syntax rules that were matched.
