I have to develop a plugin for a program that uses dongle to activate.Just wondering can i crack the key of the usb or something else?

1 Answer

I'm sure you can, but you might be running afoul of the various legislation regarding the act of reverse engineering content protection systems. I am, of course, referring to the American DCMA statues.

In any event, as pure thought experiment, I might try the following:

• Clone the USB firmware image, and load it into a virtual USB port
• As you say, crack the key and the USB interface, and short-circuit the check in a virtual USB device.
• Locate the part of the code in the program that is doing the security check, and edit the bytecode / machine code to return successful without actually looking for the device.

NOTE: Do not contact me for services related to defeating security systems. I won't do it, and I'll probably lecture you.

Reverse engineering, also called back engineering, is the process by which a man-made object is deconstructed to reveal its designs, architecture, or to extract knowledge from the object; similar to scientific research, the only difference being that scientific research is about a natural phenomenon.^[1]:3

Reverse engineering is applicable in the fields of mechanical engineering, electronic engineering, software engineering, chemical engineering,^[2] and systems biology.^[3]

Overview[edit]

There are many reasons for performing reverse engineering in various fields. Reverse engineering has its origins in the analysis of hardware for commercial or military advantage.^[4]:13 However, the reverse engineering process in itself is not concerned with creating a copy or changing the artifact in some way; it is only an analysis in order to deduce design features from products with little or no additional knowledge about the procedures involved in their original production.^[4]:15 In some cases, the goal of the reverse engineering process can simply be a redocumentation of legacy systems.^[4]:15[5] Even when the product reverse engineered is that of a competitor, the goal may not be to copy them, but to perform competitor analysis.^[6] Reverse engineering may also be used to create interoperable products and despite some narrowly tailored United States and European Union legislation, the legality of using specific reverse engineering techniques for this purpose has been hotly contested in courts worldwide for more than two decades.^[7]

Software reverse engineering can help to improve the understanding of the underlying source code for the maintenance and improvement of the software, relevant information can be extracted in order to make a decision for software development and graphical representations of the code can provide alternate views regarding the source code, which can help to detect and fix a software bug or vulnerability. Frequently, as some software develops, its design information and improvements are often lost over time, but this lost information can usually be recovered with reverse engineering. This process can also help to cut down the time required to understand the source code, reducing the overall cost of the software development.^[8] Reverse engineering can also help to detect and eliminate a malicious code written to the software with better code detectors. Reversing a source code can be used to find alternate uses of the source code, such as to detect unauthorized replication of the source code where it wasn't intended to be used, or to reveal how a competitors product was built.^[1] This process is commonly used for 'cracking' software and media to remove their copy protection,^[1]:7 or to create a (possibly improved) copy or even a knockoff, which is usually the goal of a competitor or a hacker.^[1]:8Malware developers often use reverse engineering techniques to find vulnerabilities in an operating system (OS), in order build a computer virus that can exploit the system vulnerabilities.^[1]:5 Reverse engineering is also being used in cryptanalysis in order to find vulnerabilities in substitution cipher, symmetric-key algorithm or public-key cryptography.^[1]:6

In addition to these purposes there are other uses to reverse engineering:

• Interfacing. Reverse engineering can be used when a system is required to interface to another system and how both systems would negotiate is to be established. Such requirements typically exist for interoperability.
• Military or commercialespionage. Learning about an enemy's or competitor's latest research by stealing or capturing a prototype and dismantling it, which may result in development of a similar product, or a better countermeasure against it.
• Obsolescence. Integrated circuits are often designed on proprietary systems, and built on production lines which become obsolete in only a few years. When systems using these parts can no longer be maintained (since the parts are no longer made), the only way to incorporate the functionality into new technology is to reverse engineer the existing chip and then redesign it using newer tools, using the understanding gained as a guide. Another obsolescence originated problem which can be solved by reverse engineering is the need to support (maintenance and supply for continuous operation) existing, legacy devices which are no longer supported by their original equipment manufacturer (OEM). This problem is particularly critical in military operations.
• Product security analysis. To examine how a product works by determining the specifications of its components and estimate costs, identifying potential patent infringement. Also part of product security analysis is acquiring sensitive data by disassembling and analysing the design of a system component.^[9] Another intent may be to remove copy protection, or circumvention of access restrictions.
• Competitive technical intelligence. Understand what one's competitor is actually doing, versus what they say they are doing.
• Saving money. When one finds out what a piece of electronics is capable of, it can spare a user from purchase of a separate product.
• Repurposing. When obsolete objects are reused in a different but useful manner.

Common situations[edit]

Reverse engineering of machines[edit]

As computer-aided design (CAD) has become more popular, reverse engineering has become a viable method to create a 3D virtual model of an existing physical part for use in 3D CAD, CAM, CAE or other software.^[10] The reverse-engineering process involves measuring an object and then reconstructing it as a 3D model. The physical object can be measured using 3D scanning technologies like CMMs, laser scanners, structured light digitizers, or Industrial CT Scanning (computed tomography). The measured data alone, usually represented as a point cloud, lacks topological information and design intent. The former may be recovered by converting the point cloud to a triangular-faced mesh. Reverse engineering aims to go beyond producing such a mesh, and to recover the design intent in terms of simple analytical surfaces where appropriate (planes, cylinders, etc), as well as possibly NURBS surfaces, to produce a boundary-representation CAD model. Recovery of such a model allows a design to be modified to meet new requirements, a manufacturing plan to be generated, etc.

Hybrid Modelling is a commonly used term when NURBS and Parametric modelling are implemented together. Using a combination of geometric and freeform surfaces can provide a powerful method of 3D modelling. Areas of freeform data can be combined with exact geometric surfaces to create a hybrid model. A typical example of this would be the reverse engineering of a cylinder head, which includes freeform cast features, such as water jackets and high tolerance machined areas.^[11]

Reverse engineering is also used by businesses to bring existing physical geometry into digital product development environments, to make a digital 3D record of their own products, or to assess competitors' products. It is used to analyse, for instance, how a product works, what it does, and what components it consists of, estimate costs, and identify potential patent infringement, etc.

Value engineering is a related activity also used by businesses. It involves de-constructing and analysing products, but the objective is to find opportunities for cost cutting.

Reverse engineering of software[edit]

In 1990, the Institute of Electrical and Electronics Engineers (IEEE) defined reverse engineering as 'the process of analyzing asubject system to identify the system's components and their interrelationships, and to create representations of the system in another form or at a higherlevel of abstraction', where the 'subject system' is the end product of software development. Reverse engineering is a process of examination only: the software system under consideration is not modified (which would make it re-engineering or restructuring). Reverse engineering can be performed from any stage of the product cycle, not necessarily from the functional end product.^[8]

There are two components in reverse engineering: redocumentation and design recovery. Redocumentation is the creation of new representation of the computer code so that it is easier to understand. Meanwhile, design recovery is the use of deduction or reasoning from general knowledge or personal experience of the product in order to fully understand the product functionality.^[8] It can also be seen as 'going backwards through the development cycle'.^[12] In this model, the output of the implementation phase (in source code form) is reverse-engineered back to the analysis phase, in an inversion of the traditional waterfall model. Another term for this technique is program comprehension.^[5] The Working Conference on Reverse Engineering (WCRE) has been held yearly to explore and expand the techniques of reverse engineering.^[1][13]Computer-aided software engineering (CASE) and automated code generation have contributed greatly in the field of reverse engineering.^[1]

Software anti-tamper technology like obfuscation is used to deter both reverse engineering and re-engineering of proprietary software and software-powered systems. In practice, two main types of reverse engineering emerge. In the first case, source code is already available for the software, but higher-level aspects of the program, perhaps poorly documented or documented but no longer valid, are discovered. In the second case, there is no source code available for the software, and any efforts towards discovering one possible source code for the software are regarded as reverse engineering. This second usage of the term is the one most people are familiar with. Reverse engineering of software can make use of the clean room design technique to avoid copyright infringement.

On a related note, black box testing in software engineering has a lot in common with reverse engineering. The tester usually has the API, but their goals are to find bugs and undocumented features by bashing the product from outside.^[14]

Other purposes of reverse engineering include security auditing, removal of copy protection ('cracking'), circumvention of access restrictions often present in consumer electronics, customization of embedded systems (such as engine management systems), in-house repairs or retrofits, enabling of additional features on low-cost 'crippled' hardware (such as some graphics card chip-sets), or even mere satisfaction of curiosity.

Binary software[edit]

Binary reverse engineering is performed if source code for a software is unavailable.^[1] This process is sometimes termed Reverse Code Engineering, or RCE.^[15] As an example, decompilation of binaries for the Java platform can be accomplished using Jad. One famous case of reverse engineering was the first non-IBM implementation of the PCBIOS which launched the historic IBM PC compatible industry that has been the overwhelmingly dominant computer hardware platform for many years. Reverse engineering of software is protected in the U.S. by the fair use exception in copyright law.^[16] The Samba software, which allows systems that are not running Microsoft Windows systems to share files with systems that are, is a classic example of software reverse engineering,^[17] since the Samba project had to reverse-engineer unpublished information about how Windows file sharing worked, so that non-Windows computers could emulate it. The Wine project does the same thing for the Windows API, and OpenOffice.org is one party doing this for the Microsoft Office file formats. The ReactOS project is even more ambitious in its goals, as it strives to provide binary (ABI and API) compatibility with the current Windows OSes of the NT branch, allowing software and drivers written for Windows to run on a clean-room reverse-engineered Free Software (GPL) counterpart. WindowsSCOPE allows for reverse-engineering the full contents of a Windows system's live memory including a binary-level, graphical reverse engineering of all running processes.

Another classic, if not well-known example is that in 1987 Bell Laboratories reverse-engineered the Mac OS System 4.1, originally running on the Apple Macintosh SE, so they could run it on RISC machines of their own.^[18]

Binary software techniques[edit]

Reverse engineering of software can be accomplished by various methods.The three main groups of software reverse engineering are

1. Analysis through observation of information exchange, most prevalent in protocol reverse engineering, which involves using bus analyzers and packet sniffers, for example, for accessing a computer bus or computer network connection and revealing the traffic data thereon. Bus or network behavior can then be analyzed to produce a stand-alone implementation that mimics that behavior. This is especially useful for reverse engineering device drivers. Sometimes, reverse engineering on embedded systems is greatly assisted by tools deliberately introduced by the manufacturer, such as JTAG ports or other debugging means. In Microsoft Windows, low-level debuggers such as SoftICE are popular.
2. Disassembly using a disassembler, meaning the raw machine language of the program is read and understood in its own terms, only with the aid of machine-language mnemonics. This works on any computer program but can take quite some time, especially for someone not used to machine code. The Interactive Disassembler is a particularly popular tool.
3. Decompilation using a decompiler, a process that tries, with varying results, to recreate the source code in some high-level language for a program only available in machine code or bytecode.

Software classification[edit]

Software classification is the process of identifying similarities between different software binaries (for example, two different versions of the same binary) used to detect code relations between software samples. This task was traditionally done manually for several reasons (such as patch analysis for vulnerability detection and copyright infringement) but nowadays can be done somewhat automatically for large numbers of samples.

This method is being used mostly for long and thorough reverse engineering tasks (complete analysis of a complex algorithm or big piece of software). In general, statistical classification is considered to be a hard problem and this is also true for software classification, therefore there aren't many solutions/tools that handle this task well.

Source code[edit]

A number of UML tools refer to the process of importing and analysing source code to generate UML diagrams as 'reverse engineering'. See List of UML tools.

Although UML is one approach to providing 'reverse engineering' more recent advances in international standards activities have resulted in the development of the Knowledge Discovery Metamodel (KDM). This standard delivers an ontology for the intermediate (or abstracted) representation of programming language constructs and their interrelationships. An Object Management Group standard (on its way to becoming an ISO standard as well), KDM has started to take hold in industry with the development of tools and analysis environments which can deliver the extraction and analysis of source, binary, and byte code. For source code analysis, KDM's granular standards' architecture enables the extraction of software system flows (data, control, & call maps), architectures, and business layer knowledge (rules, terms, process). The standard enables the use of a common data format (XMI) enabling the correlation of the various layers of system knowledge for either detailed analysis (e.g. root cause, impact) or derived analysis (e.g. business process extraction). Although efforts to represent language constructs can be never-ending given the number of languages, the continuous evolution of software languages and the development of new languages, the standard does allow for the use of extensions to support the broad language set as well as evolution. KDM is compatible with UML, BPMN, RDF and other standards enabling migration into other environments and thus leverage system knowledge for efforts such as software system transformation and enterprise business layer analysis.

Reverse engineering of protocols[edit]

Protocols are sets of rules that describe message formats and how messages are exchanged (i.e., the protocol state-machine). Accordingly, the problem of protocol reverse-engineering can be partitioned into two subproblems; message format and state-machine reverse-engineering.

The message formats have traditionally been reverse-engineered through a tedious manual process, which involved analysis of how protocol implementations process messages, but recent research proposed a number of automatic solutions.^[19][20][21] Typically, these automatic approaches either group observed messages into clusters using various clustering analyses, or emulate the protocol implementation tracing the message processing.

There has been less work on reverse-engineering of state-machines of protocols. In general, the protocol state-machines can be learned either through a process of offline learning, which passively observes communication and attempts to build the most general state-machine accepting all observed sequences of messages, and online learning, which allows interactive generation of probing sequences of messages and listening to responses to those probing sequences. In general, offline learning of small state-machines is known to be NP-complete,^[22] while online learning can be done in polynomial time.^[23] An automatic offline approach has been demonstrated by Comparetti et al.^[21] and an online approach by Cho et al.^[24]

Other components of typical protocols, like encryption and hash functions, can be reverse-engineered automatically as well. Typically, the automatic approaches trace the execution of protocol implementations and try to detect buffers in memory holding unencrypted packets.^[25]

Reverse engineering of integrated circuits/smart cards[edit]

Reverse engineering is an invasive and destructive form of analyzing a smart card. The attacker grinds away layer after layer of the smart card and takes pictures with an electron microscope. With this technique, it is possible to reveal the complete hardware and software part of the smart card. The major problem for the attacker is to bring everything into the right order to find out how everything works. The makers of the card try to hide keys and operations by mixing up memory positions, for example, bus scrambling.^[26][27]In some cases, it is even possible to attach a probe to measure voltages while the smart card is still operational. The makers of the card employ sensors to detect and prevent this attack.^[28] This attack is not very common because it requires a large investment in effort and special equipment that is generally only available to large chip manufacturers. Furthermore, the payoff from this attack is low since other security techniques are often employed such as shadow accounts. It is uncertain at this time whether attacks against CHIP/PIN cards to replicate encryption data and consequentially crack PINS would provide a cost effective attack on multifactor authentication.

Reverse engineering for military applications[edit]

Reverse engineering is often used by people in order to copy other nations' technologies, devices, or information that have been obtained by regular troops in the fields or by intelligence operations. It was often used during the Second World War and the Cold War. Well-known examples from WWII and later include:

• Jerry can: British and American forces noticed that the Germans had gasoline cans with an excellent design. They reverse-engineered copies of those cans. The cans were popularly known as 'Jerry cans'.
• Panzerschreck: The Germans captured an American Bazooka during World War II, and reverse engineered it to create the larger Panzerschreck.
• Tupolev Tu-4: In 1944, three American B-29 bombers on missions over Japan were forced to land in the USSR. The Soviets, who did not have a similar strategic bomber, decided to copy the B-29. Within three years, they had developed the Tu-4, a near-perfect copy.^[29]
• SCR-584 radar: copied by USSR after the Second World War. Known in the form a few modifications - СЦР-584, Бинокль-Д.
• V-2 rocket: Technical documents for the V2 and related technologies were captured by the Western Allies at the end of the war. The American side focused their reverse engineering efforts via operation Paperclip, which led to the development of the PGM-11 Redstone rocket.^[30] The Soviet side used captured German engineers to reproduce technical documents and plans, and work from captured hardware in order to make their clone of the rocket, the R-1. Thus began the postwar Soviet rocket program that led to the R-7 and the beginning of the space race.
• K-13/R-3S missile (NATO reporting nameAA-2 Atoll), a Soviet reverse-engineered copy of the AIM-9 Sidewinder, was made possible after a Taiwanese AIM-9B hit a Chinese MiG-17 without exploding in September 1958.^[31] The missile became lodged within the airframe, and the pilot returned to base with what Russian scientists would describe as a university course in missile development.
• BGM-71 TOW Missile: In May 1975, negotiations between Iran and Hughes Missile Systems on co-production of the TOW and Maverick missiles stalled over disagreements in the pricing structure, the subsequent 1979 revolution ending all plans for such co-production. Iran was later successful in reverse-engineering the missile and are currently producing their own copy: the Toophan.
• China has reversed engineered many examples of Western and Russian hardware, from fighter aircraft to missiles and HMMWV cars, such as the MiG-15 (which became the J-7) and the Su-33 (which became the J-15).^[32]. More recent analyses of China's military growth have pointed to the inherent limitations of reverse engineering for advanced weapon systems.^[33]
• During the Second World War, Polish and British cryptographers studied captured German 'Enigma' message encryption machines for weaknesses. Their operation was then simulated on electro-mechanical devices called 'Bombes' that tried all the possible scrambler settings of the 'Enigma' machines to help break the coded messages sent by the Germans.
• Also during the Second World War, British scientists analyzed and defeated a series of increasingly sophisticated radio navigation systems being used by the German Luftwaffe to perform guided bombing missions at night. The British countermeasures to this system were so effective that in some cases German aircraft were led by signals to land at RAF bases, believing they were back in German territory.

Overlap with patent law[edit]

Reverse engineering applies primarily to gaining understanding of a process or artifact, where the manner of its construction, use, or internal processes is not made clear by its creator.

Patented items do not of themselves have to be reverse-engineered to be studied, since the essence of a patent is that the inventor provides detailed public disclosure themselves, and in return receives legal protection of the invention involved. However, an item produced under one or more patents could also include other technology that is not patented and not disclosed. Indeed, one common motivation of reverse engineering is to determine whether a competitor's product contains patent infringements or copyright infringements.

Legality[edit]

United States[edit]

In the United States even if an artifact or process is protected by trade secrets, reverse-engineering the artifact or process is often lawful as long as it has been legitimately obtained.^[34]

Reverse engineering of computer software in the US often falls under both contract law as a breach of contract as well as any other relevant laws. This is because most end user license agreements specifically prohibit it, and U.S. courts have ruled that if such terms are present, they override the copyright law which expressly permits it (see Bowers v. Baystate Technologies^[35][36]). Sec. 103(f) of the DMCA (17 U.S.C. § 1201 (f)) says that a person who is in legal possession of a program, is permitted to reverse-engineer and circumvent its protection if this is necessary in order to achieve 'interoperability' — a term broadly covering other devices and programs being able to interact with it, make use of it, and to use and transfer data to and from it, in useful ways. A limited exemption exists that allows the knowledge thus gained to be shared and used for interoperability purposes.^[37]

European Union[edit]

EU Directive 2009/24 on the legal protection of computer programs, which superseded an earlier (1991) directive,^[38] governs reverse engineering in the European Union.^[39][40]

    (2) Notwithstanding the provisions of subsections (a)(2) and (b), a person may develop and employ technological means to circumvent a technological measure, or to circumvent protection afforded by a technological measure, in order to enable the identification and analysis under paragraph (1), or for the purpose of enabling interoperability of an independently created computer program with other programs, if such means are necessary to achieve such interoperability, to the extent that doing so does not constitute infringement under this title.
    (3) The information acquired through the acts permitted under paragraph (1), and the means permitted under paragraph (2), may be made available to others if the person referred to in paragraph (1) or (2), as the case may be, provides such information or means solely for the purpose of enabling interoperability of an independently created computer program with other programs, and to the extent that doing so does not constitute infringement under this title or violate applicable law other than this section.
    (4) For purposes of this subsection, the term 「interoperability」 means the ability of computer programs to exchange information, and of such programs mutually to use the information which has been exchanged.

40. ^The directive states:

    The unauthorised reproduction, translation, adaptation or transformation of the form of the code in which a copy of a computer program has been made available constitutes an infringement of the exclusive rights of the author. Nevertheless, circumstances may exist when such a reproduction of the code and translation of its form are indispensable to obtain the necessary information to achieve the interoperability of an independently created program with other programs. It has therefore to be considered that, in these limited circumstances only, performance of the acts of reproduction and translation by or on behalf of a person having a right to use a copy of the program is legitimate and compatible with fair practice and must therefore be deemed not to require the authorisation of the rightholder. An objective of this exception is to make it possible to connect all components of a computer system, including those of different manufacturers, so that they can work together. Such an exception to the author's exclusive rights may not be used in a way which prejudices the legitimate interests of the rightholder or which conflicts with a normal exploitation of the program.
