Accessory Authentication – part 2/3

This is Part 2 of a 3-Part series. You can find Part 1 here. Introduction In this post, we continue our deep dive comparison of the security processors used on a consumer product and an unlicensed clone. Our focus here will be comparing manufacturing process technology. We already know the sizes of both dies, so given the gate density (which can be roughly estimated from the technology node or measured directly by locating and measuring a 2-input NAND gate) it’s possible to get a rough estimate for gate count….

Accessory Authentication – Part 1/3

Introduction Manufacturers of consumer electronics often use embedded security processors to authenticate peripherals, accessories, and consumables. Third parties wishing to build unlicensed products (clones) within such an ecosystem must defeat or bypass this security for their products to function correctly. In this series, the IOActive silicon lab team will take you on a deep dive into one such product, examining both the OEM product and the clone in detail. Fundamentally, the goal of a third party selling an unlicensed product is for the host system to recognize their product as…

IOActive Presents at HARRIS 2024, a Unique Workshop for Chip Reverse Engineering | Tony Moor

The Hardware Reverse Engineering Workshop (HARRIS) is the first ever annual workshop devoted solely to chip reverse engineering, and 2024 was its second year. IOActive has been present both years, and this year I attended to see what all the fuss was about. Background The workshop is organized by the Embedded Security group of the Max Planck Institute for Security and Privacy (MPI-SP) together with Cyber Security in the Age of Large-Scale Adversaries (CASA) and

IOActive Security Advisory | Movistar 4G Router – Multiple Vulnerabilities

IOActive found that the Android Debug Bridge (ADB) is listening on all interfaces and gives access to a shell with root privileges; a malicious actor with access to the same network that the router is providing access to will have full control of the device. A malicious actor can send a specific payload to the gui.cgi using the ping_traceroute_process functionality to execute arbitrary commands as the privileged root user. IOActive saw a general lack of protection against cross-site request forgery (CSRF) attacks. CVE-2024-2414, CVE-2024-2415, CVE-2024-2416

IOActive Security Advisory | Lamassu Douro Bitcoin ATM – Multiple Vulnerabilities

Supporting security advisory/disclosure document (CVE-2024-0175, CVE-2024-0176 and CVE-2024-0177) supporting the Lamassu Douro Bitcoin ATM research by Gabriel Gonzalez, IOActive Director of Hardware Security. IOActive had access to few of these machines, specifically to Lamassu’s Douro ATM. This provided the team with the opportunity to assess the security of these devices – more specifically, to attempt to gain full control over them – assuming the role of an attacker with the same physical access to the device that a regular customer might have.

Opinion: AGI Influencing the Secure Code Review Profession

It’s tough to be a secure code reviewer. There are already over 700 programming languages according to Wikipedia, and seemingly more languages materializing every year. Expectations are high that rapid developments in Artificial Generative Intelligence (AGI) will bring a new suite of languages and security issues that’ll have an oversized impact on software development. Consequently, secure software development lifecycle (SDL) processes and security code review are having to evolve rapidly. I’m both excited and nervous about AGI advancements in the world of software development and secure…
