IoT penetration testing is a hands-on security assessment of a connected product's full ecosystem - the physical device and its hardware interfaces, the firmware, the companion mobile app, and the backend cloud and APIs that tie them together. CyberXplore's senior testers manually probe hardware debug ports such as UART and JTAG, extract and reverse-engineer firmware, and attack device-to-cloud communications, mapping every finding to the OWASP IoT Top 10. This senior-led, manual-first approach surfaces the chained, real-world attack paths that automated scanners and firmware analyzers simply cannot reach.

Why it matters
A single connected device is a foothold into your customers' networks and your own cloud backend - one weak default credential or unsigned firmware update can compromise an entire fleet.
IoT attack surface spans hardware, radio, firmware, mobile, and cloud, so flaws missed in one layer are routinely chained across the others into full device takeover.
Physical access to a device often exposes UART consoles, JTAG debug ports, and unencrypted flash that leak credentials, keys, and firmware to anyone who buys the product.
Regulators and buyers increasingly demand evidence of device security under ETSI EN 303 645, the EU Cyber Resilience Act, and the US Cyber Trust Mark before products reach the market.

Our methodology
01
Scoping & Threat Modeling
We map the full product ecosystem - device, firmware, radios, mobile apps, and cloud APIs - define rules of engagement, and build a threat model covering physical, network, and remote attackers.
02
Hardware & Interface Analysis
We inspect the PCB, identify and probe debug interfaces such as UART, JTAG, and SWI, dump flash memory, and assess physical tamper resistance and secure-boot enforcement.
03
Firmware Extraction & Reverse Engineering
We extract firmware from flash, OTA update channels, or vendor images, unpack file systems, and reverse binaries to find hardcoded secrets, weak crypto, backdoors, and insecure update mechanisms.
04
Device, Mobile & Cloud Testing
We attack device network services and wireless protocols, the companion mobile app, and the backend cloud and APIs - testing authentication, authorization, and the trust between every component.
05
Exploitation & Chaining
We safely exploit and chain weaknesses across layers to demonstrate concrete impact, such as remote takeover, fleet-wide compromise, or extraction of cross-customer data.
06
Reporting, Remediation & Retest
You receive a prioritized report with reproduction steps and evidence, and we re-test every fix to confirm it is resolved - included free.

Frequently asked questions
We assess the entire connected product: the physical device and its hardware interfaces, the firmware, the radio and network protocols, the companion mobile app, and the cloud backend and APIs. We test each layer and the trust relationships between them, since most real attacks chain weaknesses across components.
