Firmware security analysis targets connected smart hardware such as routers, cameras and industrial control equipment. It extracts, unpacks and statically analyses device firmware to detect firmware-level risks such as hard-coded credentials, debug interfaces, weak service configuration and insecure update mechanisms, providing the firmware component of security assessment and export compliance testing for connected products.

Why Firmware Security Analysis

Firmware-level issues directly affect the security baseline of the whole device: hard-coded credentials and backdoor accounts, unhardened debug interfaces and plaintext update packages all become entry points for attack. Several requirements in standards such as EN 303 645 and EN 18031 (secure updates, secure storage, communication protection) need to be verified at the firmware level, and supply-chain security management also requires a clear understanding of the firmware risk of procured equipment.

Analysis Scope

• Firmware extraction and unpacking (official update packages, extraction through UART / SPI / JTAG interfaces)
• File system analysis (sensitive information, hard-coded credentials, keys and certificates)
• Boot process and debug interfaces (serial port, console, secure boot configuration)
• Network services and default configuration (exposed services, default accounts, weak credentials)
• Update mechanisms (package signature verification, rollback protection, plaintext transmission)
• Third-party binary components (checks for known vulnerable versions)

Service Process

1. Device and firmware acquisition — confirm the device model and firmware version, and obtain firmware via the official package or hardware interfaces.

2. Unpacking analysis — unpack the firmware and map the file system structure and key components.

3. Sensitive information scanning — scan for hard-coded credentials, keys, certificates and debugging leftovers.

4. Service and configuration review — review the security of network services, boot scripts and default configuration.

5. Verification and reporting — verify suspicious findings and deliver the analysis report with remediation advice.

Deliverables

• Firmware analysis report — risk list, risk ratings and evidence records
• Remediation advice — specific fixes for firmware configuration and update mechanisms
• Retest support — verification after firmware updates to confirm that risk is closed out
