The Hardware Hacking Handbook vs Practical IoT Hacking: Which Should You Read?

Two cybersecurity books on Hardware, compared honestly: who each is for, what each does best, and which to read first.

Advanced

Breaking Embedded Security with Hardware Attacks

Jasper van Woudenberg, Colin O'Flynn

Jasper van Woudenberg and Colin O'Flynn (NewAE / ChipWhisperer) on real hardware attacks: bus sniffing, fault injection, side-channel power analysis, and the lab work that turns a black box into a known target.

Intermediate

Practical IoT Hacking

The Definitive Guide to Attacking the Internet of Things

Fotios Chantzis, Ioannis Stais, Paulino Calderon, Evangelos Deirmentzoglou, Beau Woods

Five-author guide to IoT pentesting covering hardware probing, radio (BLE / Zigbee / LoRa), embedded firmware, and the protocols that connect cheap devices to vulnerable backends.

Read this if

Embedded and IoT security researchers ready to move past firmware-only work and pick up the soldering iron. Also the right book for offensive practitioners auditing devices where the chip is the threat model: hardware wallets, automotive ECUs, smart locks, set-top boxes.

Pentesters branching into hardware and embedded targets. The book's coverage spans hardware probing (UART, JTAG, SWD), radio (BLE, Zigbee, LoRa), firmware analysis, and the protocols cheap devices speak to vulnerable backends. The most current general IoT book in print.

Skip this if

Readers who only want to read about hardware hacking. The book assumes you will buy a logic analyzer, a ChipWhisperer or similar, and break a few dev boards; without lab time, the middle chapters become abstract.

Pure software pentesters who don't want a hardware bench. Several chapters require oscilloscope, logic analyzer, or SDR access to follow.

Key takeaways

Side-channel and fault-injection attacks are no longer exotic: with sub-$300 tooling, an attacker can pull keys from MCUs that ship in shipping products today.
Bus interception (UART, JTAG, SWD, SPI flash dumps) is the unglamorous workhorse of hardware research and pays for itself across nearly every target.
Threat modeling for hardware is fundamentally different from software: physical access changes the cost curve of every attack, and the chapters on adversary models reflect that.

IoT is a stack: hardware, firmware, protocols, cloud. The book's strength is teaching all four as one continuous attack surface.
Radio attacks (BLE, Zigbee, LoRa) are now mainstream pentest territory; the chapters introducing SDR-based analysis are the practical entry point.
Firmware extraction-then-analysis is the core skill; the book's hardware chapters cover the extraction half, then hand off to standard binary-analysis tooling for the rest.

How they compare

We rate The Hardware Hacking Handbook higher (5/5 against 4/5 for Practical IoT Hacking). For most readers, that means The Hardware Hacking Handbook is the primary pick and Practical IoT Hacking is a useful follow-up.

The Hardware Hacking Handbook is pitched at advanced level. Practical IoT Hacking is pitched at intermediate level. Read the easier one first if you're not yet comfortable with the topic.

The Hardware Hacking Handbook and Practical IoT Hacking both cover Hardware, Embedded, so reading them in sequence reinforces the same material from different angles.
