20140359588 | SYSTEMS AND METHODS FOR REMOTE ANALYSIS OF SOFTWARE APPLICATIONS - A system for testing a software application receives one or more object spaces extracted from a development or runtime environment of the software application. The extracted object space includes information about various objects associated with the software application, its dependencies, and/or environment, and some of the objects may be dynamically created and/or modified. The extracted object space does not include any source code. A language dependent extraction component can extract the object space using introspections and/or reflection APIs. The extracted object can be translated into a language-independent format and can be analyzed to identify any vulnerabilities in the software application without access to the source code, compiled binary, and runtime environment of the software application. | 12-04-2014 |
20150106795 | SOFTWARE ANALYSIS FRAMEWORK - 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. | 04-16-2015 |
