Why Pentest IoT Devices?

Performing penetration testing on IoT devices is crucial to securing embedded systems that often operate with limited resources, weak authentication, and outdated firmware—making them attractive targets for attackers. These devices, which frequently control sensitive operations in homes, healthcare, manufacturing, and critical infrastructure, can be exploited to gain unauthorized access, disrupt services, or pivot into broader networks. Penetration testing techniques such as firmware extraction, UART/JTAG debugging, side-channel analysis, and radio frequency analysis using tools like Binwalk, Ghidra, Shodan, JTAGulator, and RFExploit help uncover hardcoded credentials, misconfigured services, and insecure communications. Testing is guided by standards like OWASP IoT Top 10, NIST SP 800-213, and ETSI EN 303 645, which provide frameworks for evaluating IoT security throughout the product lifecycle. Regularly testing and securing IoT devices helps manufacturers and integrators mitigate risks, protect user data, and maintain the resilience of interconnected ecosystems.
