Abstract:
A digital good offered for downloading from a first computing system to a client computing device for execution by a browser executing on the client is identified. The digital good is received at a third computing system, where source code for the received digital good includes scripting language code. The code is re-written to include tracking code to track behavior of the digital good during execution of the digital good, and the re-written digital good is executed in a browser run by the third computing system. Based on evaluation of results of executing the re-written digital good, it is automatically determined, by the third computer system, whether the digital good violates one or more predetermined conditions, and based on the determination of whether the digital good violates a predetermined conditions, it is automatically determined whether to discourage downloading the digital good to, or executing the digital good by, the client.
Abstract:
A program binary file is identified as part of a webpage, where the file can be downloaded from the webpage for execution by a client. A browser-executable web application or browser extension that is installed on a client computing device as a consequence of executing the program binary is identified, where source code for the web application or browser extension includes scripting language code. The source code of the web application or browser extension is re-written to include tracking code to track behavior during execution of the re-written web application or browser extension. It is determined whether execution of the re-written web application or browser extension violates one or more predetermined conditions. Then, it is determined whether to discourage downloading the program binary from the webpage to the client computing device or whether to disable execution of the web application or browser extension on the client.
