Reversing UEFI by execution

Hall 2
Jethro Beekman
This talk will be an overview of how to reverse-engineer Unified Extensible Firmware Interface (UEFI) firmware, the replacement for BIOS. Various useful tools will be discussed, including those written by the presenter and those written by others. One of the highlights will be a tool that enables running parts of the firmware in userspace on a standard Operating System.
The Unified Extensible Firmware Interface (UEFI) is a programming environment quite different from regular Operating Systems models, and as such reverse engineering UEFI software is quite different from reversing standard software. This talk will consits of three parts. First, an overview of UEFI and what makes it different will be presented. Then, existing and new tools that aid in reversing UEFI are discussed, including a demonstration of the efiperun tool that enables running UEFI modules in userspace. The talk will conclude with the recounting of a succesful reverse engineering project to uncover the Lenovo hard drive password hashing algorithm. Jethro Beekman is a security researcher and Ph.D. student at the University of California, Berkeley. He has a broad range of interests in technology, ranging from electronics to cryptography. Recent work has focused on various topics such as side-channels, remote attestation, Heartbleed and the Rust programming language.

Unser Vortrag demonstriert einen PLC-only Wurm. Der PLC-Wurm kann selbstständig ein Netzwerk nach Siemens Simatic S7-1200 Geräten in den Versionen 1 bis 3 durchsuchen und diese befallen. Hierzu ist keine Unterstützung durch PCs oder Server erforderlich. Der Wurm „lebt“ ausschließlich in den PLCs.

Key-Loggers are cool, really cool. It seems, however, that every conceivable aspect of key-logging has already been covered: from physical devices to hooking techniques. What possible innovation could be left in this field?

For years SCADA StrangeLove team speaks about vulnerabilities in Industrial Control Systems. Now we want to show by example of railway the link between information security and industrial safety and demonstrate how a root access gained in a few minutes can bring to naught all the years of efforts that were devoted to the improvement of fail-safety and reliability of the ICS system. Railroads is a complex systems and process automation is used in different areas: to control power, switches, ...
