Product Testing & Code Review

About the service

The team of technical experts at Effectual Services has been improving litigation outcomes by providing critical evidence mining support through physical product testing, source code review, advanced document review, reverse engineering and tear down report analysis. We have experience of working with a number of litigation law firms, expert witnesses and across a number of technologies for such services. We maintain a good inventory of products, software’s, test set-ups, development and testing kits and are able to prove infringement and prepare claim charts in a short time with the required depth and details in an inexpensive manner.

Methodology

Following steps are performed for product testing and source code review

Setting Objectives and Scope

Acquisition (purchasing or arranging the device/product to be tested).

Disassembly or dismantling

Component Analysis (such as PCB, display, chip, BUS architecture etc) or software code analysis (java, C++, python, html, etc.)

Data collection and analysis (security protocol SSL/TLS, authentication access control, secure boot analysis, communication flow)

Case Study

We performed accelerometer signal analysis of a Smartphone using reverse engineering. Here is an example of how we used reverse engineering to analyze the accelerometer signals associated with the Smartphone’s motion detection feature
  • Identifying the connector on the motherboard of the Smartphone to which the accelerometer is connected.
  • Soldering jumper wires to the points of interest on the connector.
  • Connecting the jumper wires to an oscilloscope.
  • Powering on the Smartphone and move it around.
  • Observing the signals on the oscilloscope to understand how they change when the Smartphone is moved.
We performed reverse engineering and tear down to analyze the signals that control the PTZ camera motor's pan and tilt functions. We performed the following steps
  • Identifying the connector on the motor's controller board to which the pan and tilt motors are connected.
  • Soldering jumper wires to the points of interest on the connector.
  • Connecting the jumper wires to a logic analyzer.
  • Powering on the PTZ camera and move the camera's pan and tilt axes.
  • Observing the signals on the logic analyzer to understand how they change when the camera's pan and tilt axes are moved.
We performed a source code analysis using browser's web development tool to detect various page load parameters. We performed the following steps
  • First running the website and opening web inspector tool.
  • Checking the different timestamp displayed in the performance option.
  • irst time stamp can be inferred as the time when request is send and end time is the time when page load completes.
  • Further, we also checked server response time in the network option.
  • Finally, using these different time stamps, we calculated page load time and first response time.

FAQ

Reverse engineering is the process of disassembling a system or component to understand its design and function.

Reverse engineering can be used for a variety of purposes, such as:
  • To understand how a system or component works
  • To identify and fix security vulnerabilities
  • To develop new products and services that are compatible with existing systems
  • To improve the performance or reliability of existing systems

The legality of reverse engineering varies depending on the jurisdiction. In general, it is legal to reverse engineer systems and components for personal use or for the purpose of research. However, it may be illegal to reverse engineer systems and components that are protected by copyright or trade secrets.

Source code analysis is the process of examining the source code of a program to identify potential problems or areas for improvement.

Source code analysis can be used for a variety of purposes, such as:
  • To identify and fix security vulnerabilities
  • To improve the performance or reliability of a program
  • To understand how a program works
  • To develop new features for a program

There are a variety of tools available for source code analysis. Some of the most popular tools include:
  • Static analysis tools : These tools analyze the source code of a program without executing it. They can identify potential problems such as syntax errors, coding errors, and security vulnerabilities.
  • Dynamic analysis tools : These tools analyze the source code of a program by executing it. They can identify potential problems such as performance issues and memory leaks.

Reverse engineering and source code analysis can be challenging tasks, especially for complex systems and programs. Some of the challenges include:
  • Understanding the system or program's architecture
  • Identifying the different components of the system or program
  • Understanding how the components interact with each other
  • Identifying the signals that control the system or program

Reverse engineering and source code analysis can provide a number of benefits, such as:
  • Improved understanding of how systems and programs work
  • Identification and fixing of security vulnerabilities
  • Development of new products and services that are compatible with existing systems
  • Improvement of the performance and reliability of existing systems
