Presently described is a decompilation method of operation and system for parsing executable code, identifying and recursively modeling data flows, identifying and recursively modeling control flow, and iteratively refining these models to provide a complete model at the nanocode level. The nanocode decompiler may be used to determine if flaws, security vulnerabilities, or general quality issues exist in the code. The nanocode decompiler outputs in a standardized, human-readable intermediate representation (IR) designed for automated or scripted analysis and reporting. Reports may take the form of a computer annotated and/or partially human annotated nanocode listing in the above-described IR. Annotations may include plain English statements regarding flaws and pointers to badly constructed data structures, unchecked buffers, malicious embedded code or “trap doors,” and the like. Annotations may be generated through a scripted analysis process or by means of an expert-enhanced, quasi-autonomous system.

A script analyzer with change guide generates accurate test scripts for evolving applications. Applications often have complex graphical user interfaces for which the permutations and combinations of GUI elements give rise to an enormous field of potential commands and command sequences to be tested. Furthermore, these applications change over time, rendering prior test scripts unworkable. The script analyzer automatically generates new test scripts to reliably test subsequent application versions, while greatly reducing the time, cost, and resource expenditures needed to arrive at subsequent application versions.

A method and system for analyzing scripts. A script is processed, which executes text blocks of code derived from the script and copied to an output file in a sequential order. The script is the first text block that is copied to the output file. Executing the text blocks includes interpreting each text block to generate and execute a corresponding interpreted block of code. Processing the script results in the text blocks being sequenced in the output file in the sequential order. The text blocks include an original text block of code that includes text that may be directly inferred from text appearing in the script. The blocks of code include a new text block of code, which includes text that may not be directly inferred from text appearing in the script. The new text block is generated from executing the original text block.

One embodiment relates to a computer-implemented method for detecting malicious scripts in web pages. A local engine and an application are executed at a client computer. The local engine intercepts an access by the application to a web page at a universal resource locator (URL) under a domain. The local engine determines scripts at the URL and scripts at other URLs under the domain. Using that information, the local engine determines if the scripts at the URL include one or more unique script(s). The local engine sends the unique script(s), if any, via a network to a script analyzer. The script analyzer may then perform emulation of the unique script(s) to detect malicious code therein. Other embodiments, aspects and features are also disclosed.
