The present use of obfuscators as tools for application of protection from snooping and decompilation/disassembly requires more sophisticated obfuscators.
In the past it was considered that obfuscators converted IL-code and metadata into something meaningless and difficult to recognize. The situation appears to be completely different today.
Methods of code development and maintenance have become very sophisticated. A completely different protection level is required as well as additional support services, analysis and maintenance of the code for large projects and for various configurations/packages is required.
Obfuscators do offer the possibility to convert IL-code and its structure into a difficult-to-read and hard to decompile file, protecting the code from hackers and competitors. Apart from that,
hackers and competitors have very efficient tools for the decompilation, deobfuscation and forging of the IL-code and therefore it is necessary to withstand exploitations of this vulnerability. Modern obfuscators expand their realm of this application.
Spices.Obfuscator (one of the products of the Spices.Net family) developed by the 9Rays.Net, Inc. company offers this entire array of applications making it a state of the art development tool.
Its features are listed as follows.
Most companies have quite complicated build-processes requiring flexibility and yet specific scripts. MSBuild support included in Spices.Obfuscator allows easy integration of the obfuscation process into the build process in the form of automation, thereby making Spices.Obfuscator more flexible. Obfuscation script can be written using C#, VB.Net, C++ or J# by integrating Spices.Obfuscator into one's own build-solutions.
Spices.Project and Spices.Solution both support launching of various solutions in the process of obfuscation at any step.
With Spices.Obfuscator it is possible to debug applications after the obfuscation. Thorough integration with Visual Studio 2003/2005 allows obfuscating applications right within the build process and launching of the obfuscated application in the debug mode.
Besides this, means of tracing exceptions is offered, allowing the receipt of the original method of stack trace which eventually results in quick analysis and correction of errors.
Support of Large Projects and Various Project Configurations
Many software manufacturers develop several software versions: evaluation version, pro version, light version, etc. They require different obfuscation modes for different versions. Spices.Solution can enable this to happen since it is a collection of projects (each of which contains one of the product configurations), which allow obfuscating various product configurations at a time.
This is a new patent pending technology that is including several methods to complicate code analysis and decompilation.
Spices.Anonymizer factually converts the code monolith of the protected application into sand, substantially complicating the process of analysis of the applications, the search of the vulnerable points for hackers as well as protecting applications from ILASM/ILDASM roundtrip.
This technology only insignificantly reduces the code efficiency. It is flexible in operational control and it allows several protection levels, where even the minimal level of protection considerably increases the security of the applications and the complication of their analysis.
It is not a secret that software developers spend a lot of efforts to provide security for their applications, hide secret information from hackers and substantially complicate its search in bytecode.
StringEncryption technology used by Spices.Obfuscator offers several levels of security ranging from removing strings from the code to string encryption using the TripleDES algorithm. Spices.Anonymizer technology foresees the possibility of code anonymization that is responsible for the information encryption in order to prevent the decompilation software from recognizing decryption methods.
Obfuscators do not only rename assembly members but optimize the assembly in size and efficiency as well. The obfuscation effect, which changes the names of the assembly members to shorter ones, increases the efficiency of the applications. Assemblies may contain code and metadata that do not have to be held in the obfuscated assembly. They are superfluous and should be deleted and by doing so reduce the assembly size. The technology used in Spices.Obfuscator allows 50% reduction of the metadata assembly size. This size reduction leads to faster initialization of the assembly and a significant increase of efficiency. Some methods used by Spices.Optimizer complicate the tasks of hacking and assembly research as well as ILDASM/ILASM roundtrip.
Localization as you know it in developmental tools such as Visual Studio does not allow localization of all of the string and application resources. Localized information must be constantly updated by updating the assembly process of the application with respect to the localization.
Spices.Obfuscator offers a convenient solution of this issue. By means of one of the tools contained in the Spices.Net – Spices.Localizer, a user can extract all the string and resource information from the assembly, obtain localization tables and perform localization of the required information to any language.
Spices.Localizer also offers line synchronization for localization with the current code version, which substantially reduces the assembly time and allows distribution of the tasks between the developers to be more efficient. After the localization tables are completed, they can be used while obfuscating and all the localized information will be implemented in the code. If string encryption is used, localized information will be encrypted as well.
Tamper-proof /anti Spoofing
If hackers were not attracted to the first .net versions, the growing popularity of them nowadays brings it to their attention. The .Net software uses assembly signing technology, converting the file into a strong-named assembly. At startup, such files are checked for digital signature that is kept in the assembly and confirms that since the moment of assembly signing its content hasn't changed. This is a good solution that allows avoiding corruption and modification of the assembly, but the signing technology has its weaknesses.
For instance, a hacker can remove an assembly signature, modify an assembly and re-sign it using his own key, forging the assembly by doing so. This is one of the widely used methods of .Net code hacking.
Spices.Obfuscator offers solutions to protect code from such hacking attacks by regenerating tamper-proof assembly that is very hard to forge (this is a patent pending technology as well). Experts at 9Rays.Net are working daily to improve this technology.
In order to assure that an assembly has been properly obfuscated, Spices.Obfuscator also includes the possibility of assembly verification after obfuscation and optimization.
Additional Means of Analysis, Browsing and Search
One very advantageous feature of Spices.Obfuscator is the fact that it contains additional means of analysis, browsing and verification of assemblies. The package includes a disassembler, an analyzer of call graphs, inheritance and interface implementation. A user can obtain complete context information about a current assembly member when browsing the assembly members, as well as when searched by name or token. The package also includes means for low level browsing and analysis of metadata ranging from the metadata table structure to the structure of PE-files (portable executable format). The package also includes a means of obtaining diagrams depicting various relations between the assemblies and their members. In other words Spices.Obfuscator presents not only the means of protection but serves as a tool for the analysis of the assembly architecture as well as the supplier of practically any information about the assembly that may be needed.
Assembly, Classes Merging & Linking
In the next versions of Spices.Obfuscator, The 9Rays.Net Company plans to develop a Class/Assembly Linker that will allow assembly manipulations such as assembly merging, splitting and extraction of classes from an assembly. Such services are in demand and as you can see, they expand the applicability of obfuscators.
As we can see Spices.Obfuscator offers a wide set of services and means that not only protect software from competitors and hackers, but also optimizes applications in size and efficiency. It can flexibly accompany the most sophisticated build-process and large projects, as well as serve as a supplier of information for browsing, analysis and verification of .Net applications.
