Detile: Fine-Grained Information Leak Detection in Script Engines
Robert Gawlik, Philipp Koppe, Benjamin Kollenda +3
Memory disclosure attacks play an important role in the exploitation of memory corruption vulnerabilities. By analyzing recent research, we observe that bypasses of defensive solut…
An Exploratory Analysis of Microcode as a Building Block for System Defenses
Benjamin Kollenda, Philipp Koppe, Marc Fyrbiak +3
Microcode is an abstraction layer used by modern x86 processors that interprets user-visible CISC instructions to hardware-internal RISC instructions. The capability to update x86…
Breaking and Fixing Destructive Code Read Defenses
Jannik Pewny, Philipp Koppe, Lucas Davi +1
Just-in-time return-oriented programming (JIT-ROP) is a powerful memory corruption attack that bypasses various forms of code randomization. Execute-only memory (XOM) can potential…
Steroids for DOPed Applications: A Compiler for Automated Data-Oriented Programming
Jannik Pewny, Philipp Koppe, Thorsten Holz
The wide-spread adoption of system defenses such as the randomization of code, stack, and heap raises the bar for code-reuse attacks. Thus, attackers utilize a scripting engine in…
Reverse Engineering x86 Processor Microcode
Philipp Koppe, Benjamin Kollenda, Marc Fyrbiak +4
Microcode is an abstraction layer on top of the physical components of a CPU and present in most general-purpose CPUs today. In addition to facilitate complex and vast instruction…
Interdiction in Practice -- Hardware Trojan Against a High-Security USB Flash Drive
Pawel Swierczynski, Marc Fyrbiak, Philipp Koppe +2
As part of the revelations about the NSA activities, the notion of interdiction has become known to the public: the interception of deliveries to manipulate hardware in a way that…
