JTAGulator®
On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available OCD interfaces can be a difficult and time consuming task, sometimes requiring physical destruction or modification of the device.

Adventures of Wallet Hacking
With his team at offspec.io, Joe Grand has been hacking cryptocurrency wallets to help people recover funds they once thought were lost forever. In this photographic slideshow, Joe shares his experiences and technical challenges, including work on the Trezor One, Ledger Nano S, and Samsung Galaxy S3. [ continue ]
Trezor One Fault Injection
Fault injection, also known as ‘glitching,’ is a process to intentionally cause a system to misbehave in a way that is beneficial to an attacker. This technique is commonly used to defeat a microcontroller’s security mechanism, which is intended to protect access to its debug interface and/or internal memory/data. [ continue ]
Hardware Hacking Party Tricks
The way electronic products are attacked is continually evolving. What used to be complex tasks requiring specialized equipment and/or knowledge are now possible with open source tools and resources created by hackers for hackers. We can take advantage of this widespread availability to more thoroughly break systems or to understand how our products might be approached by an adversary. [ continue ]
