Reverse engineering duck and cover torrent

The key in reverse engineering a mechanical part, is to know how the part was produced, as it will determine how the part will be reverse engineered. For example, if a part was created by machining, then the part can be reverse engineered by visualizing how the part was machined.

The geometry of a machined part will be limited to what can be achieved by removing material from the sides of the stock, as machining is a subtractive method.

In contrast, a casted part can have complex internal geometry that sometimes cannot be seen from the outside. Features like this are possible as casting is an additive method. In addition to these two methods, there are numerous other ways to manufacture a mechanical part. By knowing how the part was manufactured, the engineer can get a better idea on the design intent that went into creating the original part.

For this project we used Solidworks and Xtract 3D to perform the reverse engineering. After importing the mesh into Solidworks, we checked if the mesh was aligned to the correct axis. Every reverse engineer, malware analyst or simply a researcher eventually collects a set of utility software that they use on a daily basis to analyze, unpack, and crack other software.

This article will cover mine. It will be useful to anyone who has not yet collected their own toolset and is just starting to look into the subject. However, an experienced reverse engineer must also be curious about what other crackers are using. This article is for information purposes only.

Debugging an application is an essential part of studying it, so every reverse engineer needs a debugger at the ready. A modern debugger must support both Intel architectures x64 and x86 , so this is the first prerequisite. We must also be able to debug kernel-mode code. You will need this every once in a while, especially if you want to look for zero-day vulnerabilities in OS kernels or reverse engineer malware in drivers. The main candidates are x64dbg and WinDbg.

The first debugger works in user mode, while the second one can debug kernel-mode code. This is a modern debugger with a good user interface, a worthy successor of OllyDbg. It supports both architectures x64 and x86 , and there are tons of useful plugins. Granted, it has its downsides as there are a number of annoying bugs. But it is actively developed and supported. Since the debugger works in user mode, it is of course vulnerable to a wide range of anti-debugging techniques.

This is, however, in part offset by the availability of many different debugger hiding plugins. This debugger has enabled some hackers to break down the infamous Denuvo DRM system! It does not support the latest operating systems or x OllyDbg is undoubtedly a milestone piece of software, but now it seems that its time has passed.

Official homepage. WinDbg is one of the best kernel or driver debugging tools. This is currently the most up-to-date and powerful kernel code debugger.

WinDbg supports remote debugging and can download debug symbols directly from Microsoft servers. Reverse engineering cannot exist without static code analysis tools.

The current selection of disassemblers is not much better than that of debuggers, but there we still have some favorites. The IDA Pro disassembler is a de facto standard in antivirus labs.

The free version is limited to x86 and does not support plugins. If you would like to receive our regular newsletter, please follow this link and complete the form:.

Reverse Engineering There is a new, updated version of this news post here: The role of reverse engineering in modern product design What is reverse engineering?

Why would you need reverse engineering? Recovering data and designs lost during company transition, data corruption or IT failures Product Improvement Whatever the need, reverse engineering can shine a light on the processes involved in the creation of the product in question — whether this is to establish details of an existing technologies or an unusual device, or simply to determine technical aspects of an established product that may not have been manufactured for some time.

Product Improvement Product improvement can be a significant driver in wanting to RE a product. Reducing manufacturing cost Refining product performance Replacement of a product Designers and engineers are always looking for ways to improve both novel concepts and existing products. How do you reverse engineer? Design intent capture The design team will start by measuring components using digital, traditional and sometimes non-contact methods to define the parts.

There are several tools within the CAD environment to achieve accurate design capture: Interference checking to ensure the parts can operate with sufficient clearance or are purposely interfering such as self-tapping screws etc Wall thickness analyses to ensure that for example a moulding has not been modelled with excess wall thickness which would potentially cause problems in moulding further down the line Draft analyses, again with moulded components to ensure that all surfaces have been correctly drafted in the right direction.

This also helps to validate the split lines of the product. Other CAD tools that aid the process look at part volume, mass properties and undercut checking to help ensure the products parts are robust. How do you reverse engineer a very complex shape?
