TheUniversal Asynchronous Receiver-Transmitter (UART) is one of the simplest serial protocols, and its exploitation provides one of the easiest ways to gain access to IoT devices. Vendors typically use it for debugging.
Now, connecting the UART pins to a USB TTL-to-Serial device, one an access this serial console via a utility such as minicom or screen. Executing screen /dev/ttyUSB0 9600 results in a terminal showing a successful console session obtained with kernel boot logs being displayed from the GL-AR750 router!
Binwalk relies on magic values to detect files and file systems to parse.In the event data was obfuscated, encrypted or otherwise modified, it would be easy to fool binwalk into not automatically extracting firmware as seen in the previous Arch Cloud Labs blog post.
This was my first venture into hardware hacking for embedded devices.I always thought hardware hacking had an expensive cost to entry, but with this simple UART example and old inexpensive router, it was trivial to dive into this field via a $13 USD USB-to-TTL device. The continued growth of IoT devices and edge computing will be dominated by a mix of Linux systems and odd-kubernetes systems. I look forward to continuing to grow technical skills in this arena to poke at weird home devices.
The Hardware Hacking Handbook brings advanced hardware hacking techniques into your life. Along the way it touches on many aspects of hardware hacking. You can read more about the book from the Official No Starch Press page.
This companion site is a very lightweight place to hold links to the resources we reference in the book. This includes information about running the practical examples along with errors we discovered (or were told about) too late to fix in the book.
In this course students explore hardware hacking on embedded devices. Different types of embedded systems are analyzed: revealing the designs, components, security limits, and reverse-engineering challenges required to execute a hardware attack. Next the class explores hardware interfaces, ports and communication protocols, electrical signaling, tips for analyzing firmware images, and more. In the labs the student takes the role of the hacker, performing fault-injection, side-channel (SCA), and simple and differential power analysis (SPA/DPA) attacks on real devices.

As we continue to meet the challenges of COVID- 19 in 2021, the need to plan for the unexpected remains a critical component for all businesses. Of course, no one, including those of us who work in the bankruptcy system, could have foreseen the degree to which the COVID-19 pandemic would impact the ability of many businesses and governmental agencies to conduct business and the plethora of changes that would have to be made to continue operations. While this extraordinary, global crisis represents precisely the situation that calls for disaster planning, lesser emergencies occur that nevertheless may cause substantial disruption to business as usual if appropriate forethought is not taken.
What would happen if you, as a chapter 7 panel trustee, encountered an unexpected event that kept you from performing your fiduciary duties to not only administer assigned cases but also to run your trustee operations? What if there was an unexpected event that occurred in the facilities in which you conduct your chapter 7 trustee case administration, such as a fire, flood due to a water main break or other conditions that prevented you and your staff from entering your office? What if everything in your office was destroyed due to a catastrophic incident? Are you ready for the next unexpected event?
Assess Potential Risks. To develop or update your COOP, identify potential sources of business interruption. These may include natural disasters, such as hurricanes, wildfires, earthquakes and pandemics; major computer malfunctions and interruptions, such as loss of function due to area blackouts or hacking; incapacitation or death of the trustee or staff; or other man-made sources of disruption that threaten the safety of the staff.
While each trustee has discretion in establishing the exact details of his or her COOP, having and maintaining a plan is not discretionary. Consider organizing a COOP plan team comprised of essential employees. Once your COOP has been developed, provide a copy of the COOP to each employee and conduct periodic training exercises to test the efficacy of your plan.
The following are common elements of a COOP. These suggestions are by no means exhaustive, and trustees should consult the Handbook as well as emergency planning resources, which are readily available on the Internet for additional elements that may be appropriate for your trustee operation.
Communications with the United States Trustee. Maintaining regular communications with your U.S. Trustee is vital to the proper maintenance of your trustee operations. When emergencies occur, whether large or small, immediate notice to the U.S. Trustee is required. Do you and your staff know how to reach the U.S. Trustee, either directly or indirectly through the Assistant U.S. Trustee, if your emergency occurs after hours or on a weekend?
Communications with Outside Parties. The plan should include a list of key telephone numbers, including police, fire, trustee, employees, U.S. Trustee and local U.S. Trustee office, court contacts, computer hardware and software vendors, banks, landlord, insurance, utilities and other vendors. The trustee and each employee should keep a copy of the list in the office and off site.
Life Safety. The first priority should be protection of the health and safety of all staff. Take reasonable steps to secure the office[Footnote 8] and the safety of your staff. In the event of an emergency, determine whether to evacuate, seek shelter, shelter in place or initiate a lockdown.
