Embedded Device Security Testing
Embedded Device Security Testing
Embedded devices have revolutionized our world. They can be found in an extensive range of products, including digital security cameras, home appliances, vehicles, medical equipment, farming tools, and even doorbells. Despite their diversity, all these devices share one common feature: the ability to transmit data electronically, often with internet connectivity options. Embedded devices present both unique and familiar security challenges and risks compared to other technologies.
Software vulnerabilities are not exclusive to the Internet of Things (IoT), as they also exist in application development, making application security testing and reviews crucial. However, what sets IoT devices apart is that they do not have a single application but rather an entire embedded system.

Regulatory Compliance and Risk Assessment
Accessing the firmware “etched” into the hardware is not as straightforward as examining an application file or scanning passwords. IoT devices may also offer multiple ways to connect and interact with the device, potentially providing an entry point into your network from an enterprise user’s perspective, or risking sensitive proprietary data leakage from a developer’s standpoint.
Enterprises and manufacturers increasingly face growing compliance and regulatory concerns and risks. For instance, the recently amended Federal Food, Drug, and Cosmetic Act (FD&C Act) introduced section 524B, Ensuring Cybersecurity of Devices, and began setting IoT standards for embedded healthcare devices. Compliance with the U.S. Department of Commerce’s Entities List may also be necessary, and considering an embedded device may contain numerous parts from various sub-suppliers, conducting due diligence assurance assessments could significantly reduce the risk of violation.

Embedded Methodology
White Knight Labs excels at operating under a structured, repeatable methodology. We stress this concept in every engagement to ensure our findings are reliable, reproducible, and of excellent quality. As such, our embedded assessment results can always be verified by your teaj, both before and after remediation. To get these results, we adhere to the following steps:
Information Gathering
Within this phase, White Knight Labs will perform OSINT (Open Source Intelligence), documentation of device functionality, itemization of external/internal I/O connections, and utilize a number of techniques to derive an understanding of standard operating conditions, use cases, and functionality. These efforts will assist building a baseline of the assessment device’s threat landscape. The tasks executed during this phase, may include:
- FCCID / Patent data collection and analysis
- Public firmware analysis and review
- Passive Ethernet and RF analysis
- External / Internal peripheral and I/O identification
- PCB component indexing and identification
Vulnerability Identification
During this phase, White Knight Labs will deploy a number of automated and manual tools, techniques, and procedures to validate the operational integrity of critical device functionality. The goal of this effort is to identify both positive and negative controls that would allow for device compromise, data manipulation, or misuse. The tasks executed during this phase, may include:
- Destructive disassemble of the assessment device
- Firmware extraction
- PCB signal analysis and/or snooping
- Data injection, manipulation, or corruption
Device Exploitation
Having developed a full understanding of the assessment target’s threat landscape, White Knight Labs will perform targeted exploitation and validation of all observed deficiencies. The goal of this activity is to confirm expected outcomes and identify unforeseen mitigating controls. The tasks executed during this phase, may include:
- Malicious firmware installation
- Ethernet/RF Manipulator in the Middle (MitM) attacks
- Flash reprogramming or data injection
- Low level signal manipulation
Reporting and Documentation
Reporting is critical to the success of the assessment, as it provides the lasting documentation to share with management and vendors. Each report is customized to the specific scope of the assessment and risk based on the individual organization. The reports are intuitive to read, but thorough in the findings. In addition, each vulnerability includes a detailed remediation strategy. Some of the elements that you will find in our reports include:
- An executive summary for strategic direction
- A walkthrough of technical risks
- Multiple options for vulnerability remediation
- The potential impact of each vulnerability
Remediation Testing
As an additional service, White Knight Labs will revisit an assessment after an organization has had some time to patch vulnerabilities. We will retrace our steps from the engagement to ensure changes were implemented properly. Our engineers will also search for new vulnerabilities associated with the updates, such as misconfigurations in the network or flaws in a new software implementation. At this point, we will update our previous assessment to reflect the new state of the system.
