IoT ecosystems combine embedded devices, mobile apps, APIs, and cloud platforms. We assess firmware, hardware interfaces, communication protocols, backend services, and identity controls to uncover real-world exploit paths.
IoT security requires deep technical analysis across hardware and software layers.
Reverse engineering firmware to identify hardcoded credentials, insecure update mechanisms, and memory vulnerabilities.
Assessment of MQTT, Bluetooth, Zigbee, and custom communication protocols for encryption and authentication weaknesses.
Testing APIs and cloud platforms connected to IoT devices for privilege escalation and lateral movement risks.
Evaluation of UART, JTAG, and debug interfaces for unauthorized access and data extraction risks.
IoT penetration testing addresses both device-level and ecosystem-level security risks.
Yes. Our testers perform firmware extraction, reverse engineering, and hardware interface analysis where permitted.
| IoT Penetration Testing | Infrastructure Penetration Testing | |
|---|---|---|
Primary Focus | Security of connected devices, embedded systems, and firmware | Security of networks, servers, firewalls, and enterprise systems |
Scope | Smart devices, medical devices, industrial systems, sensors, gateways | Corporate networks, VPNs, Active Directory, internal and external servers |
Environment Tested | Physical devices, wireless protocols, firmware, cloud-connected device ecosystems | On-premise networks, data centers, hybrid infrastructure environments |
Common Vulnerabilities | Hardcoded credentials, insecure firmware updates, weak encryption, exposed device APIs | Open ports, unpatched services, weak segmentation, insecure remote access |
Attack Surface | Device hardware interfaces, Bluetooth/Wi-Fi, embedded web interfaces, cloud IoT platforms | External perimeter, internal network services, authentication systems |
Testing Approach | Hardware analysis, firmware extraction, protocol testing, device exploitation | Simulated attacker attempting network compromise and lateral movement |
Authentication & Access Control | Tests device-level authentication, default credentials, certificate management | Tests domain authentication, privileged accounts, and segmentation controls |
Impact if Compromised | Device takeover, operational disruption, data manipulation, safety risks | Network breach, ransomware deployment, domain compromise |
Regulatory Considerations | Often tied to medical, manufacturing, or critical infrastructure compliance | Often tied to general cybersecurity and data protection requirements |
Best For | Organizations developing, deploying, or managing connected devices | Organizations validating network and internal infrastructure defenses |
IoT environments expand your attack surface beyond traditional networks. Packetlabs IoT Penetration Testing identifies exploitable weaknesses across devices, firmware, APIs, and supporting infrastructure—so connected systems don’t become silent entry points.
Identify insecure firmware, hardcoded credentials, weak encryption, and unsafe update mechanisms that attackers can exploit at the hardware layer.
Assess Bluetooth, Zigbee, MQTT, HTTP, and other communication channels to uncover interception, spoofing, and injection risks.
Test how devices interact with APIs, cloud services, and mobile applications to prevent privilege escalation and data exposure.
Identify where telemetry, credentials, and personal data may be stored, transmitted, or logged insecurely across the ecosystem.
Assess risks where physical device access could lead to system compromise, firmware manipulation, or network pivoting.
Deliver evidence to customers, regulators, and partners that connected products are resilient against modern adversaries.
In this guide, learn why IoT Penetration Testing is an invaluable cybersecurity exercise to meet regulatory guidelines, ensure insurance parameters are met, and fortify your cyber roadmap.
