Fill Your Boots: Enhanced Embedded Bootloader Exploits Via Fault Injection and Binary Analysis
IACR Transactions on Cryptographic Hardware and Embedded Systems ISSN 2569-2925, Vol. 2021, No. 1, pp. 56–81. DOI:10.46586/tches.v2021.i1.56-81 Fill your Boots: Enhanced Embedded Bootloader Exploits via Fault Injection and Binary Analysis Jan Van den Herrewegen1, David Oswald1, Flavio D. Garcia1 and Qais Temeiza2 1 School of Computer Science, University of Birmingham, UK, {jxv572,d.f.oswald,f.garcia}@cs.bham.ac.uk 2 Independent Researcher, [email protected] Abstract. The bootloader of an embedded microcontroller is responsible for guarding the device’s internal (flash) memory, enforcing read/write protection mechanisms. Fault injection techniques such as voltage or clock glitching have been proven successful in bypassing such protection for specific microcontrollers, but this often requires expensive equipment and/or exhaustive search of the fault parameters. When multiple glitches are required (e.g., when countermeasures are in place) this search becomes of exponential complexity and thus infeasible. Another challenge which makes embedded bootloaders notoriously hard to analyse is their lack of debugging capabilities. This paper proposes a grey-box approach that leverages binary analysis and advanced software exploitation techniques combined with voltage glitching to develop a powerful attack methodology against embedded bootloaders. We showcase our techniques with three real-world microcontrollers as case studies: 1) we combine static and on-chip dynamic analysis to enable a Return-Oriented Programming exploit on the bootloader of the NXP LPC microcontrollers; 2) we leverage on-chip dynamic analysis on the bootloader of the popular STM8 microcontrollers to constrain the glitch parameter search, achieving the first fully-documented multi-glitch attack on a real-world target; 3) we apply symbolic execution to precisely aim voltage glitches at target instructions based on the execution path in the bootloader of the Renesas 78K0 automotive microcontroller. -
Jeffrey Heim, Marcel Hernandez, Maria Nunez,& Matthias Katerna Morris Worm on November 2, 1988, Robert Tappan Morris Releas
Jeffrey Heim, Marcel Hernandez, Maria Nunez,& Matthias Katerna Morris Worm On November 2, 1988, Robert Tappan Morris released a worm into the internet. The experimental worm was the first of its kind. It replicated itself and programmed itself, so it ended up spreading much faster than Morris expected. It self-programmed and self-replicated at an exponential rate in a manner that had never been seen before. Morris knew this worm was not necessarily ethical, for he released it out of MIT instead of his own Cornell University. In due course, many computers across the United States had crashed because of Morris. Once he discovered how much damage the worm had been causing, he reached out to a friend at Harvard looking for a solution to stop it. They attempted in sending an anonymous message to the network with directions that could kill the worm, but the message came through too late since they system was clogged. Many significant computers at colleges, businesses and the military became infected. The cost to fix each computer ranged from $200 to over $53,000. The worm exploited vulnerabilities in computer systems and in the UNIX email software. Within 24 hours of releasing the worm, thousands of people were aware something was unusual. Eventually, it would infect ten percent of all computers using the internet. The Morris Worm was the largest malware case ever to reach this percentage. However, the percentage was so high due to the fact that the number of computers was much less than today. The computers it impacted included significant systems, such as Stanford’s, Berkley’s and NASA’s. -

You can’t fake it . try to fake three laughs in an hour—ha ha ha ha ha—they’ll take you away, man. You can’t.2 – Lenny Bruce Abstract This note will discuss the current state of protection for jokes and comedy. As it is now, the only protection comics have is self-help, meaning comedians take punishing thefts into their own hands. This note will dive into the reasons why the current legislature and courts refuse to recognize jokes as copyrightable. -

Crime and the Internet
Crime and the Internet Is the Internet really powerful enough to enable a sixteen-year-old boy to become the biggest threat to world peace since Adolf Hitler? Are we all now susceptible to cybercriminals who can steal from us without ever having to leave the comfort of their own armchairs? These are fears which have been articulated since the popular development of the Internet, yet criminologists have been slow to respond to them. Consequently, questions about what cyber- crimes are, what their impacts will be and how we respond to them remain largely unanswered. Organised into three sections, this book engages with the various crimino- logical debates that are emerging over cybercrime. The first section looks at the general problem of crime and the internet; it then describes what is currently understood by the term ‘cybercrime’, before identifying some of the challenges that are presented for criminology. The second section explores the different types of cybercrime and their attendant problems. The final section contem- plates some of the challenges that cybercrimes give rise to for the criminal justice system.
