Remote-Timer-as-a-Service: Efficient Microarchitectural Leakage in the Cloud with Remote Timers
Martin Schwarzl, Haocheng Xiao, Albert Pedersen +2
Edge computing solutions have become a crucial part of the industry, delivering fast, flexible and scalable applications close to the end users, with typical use cases including dy…
TME-Box: Scalable In-Process Isolation through Intel TME-MK Memory Encryption
Martin Unterguggenberger, Lukas Lamster, David Schrammel +2
Efficient cloud computing relies on in-process isolation to optimize performance by running workloads within a single process. Without heavy-weight process isolation, memory safety…
Layered Binary Templating: Efficient Detection of Compiler- and Linker-introduced Leakage
Martin Schwarzl, Erik Kraft, Daniel Gruss
Cache template attacks demonstrated automated leakage of user input in shared libraries. However, for large binaries, the runtime is prohibitively high. Other automated approaches…
Systematic Analysis of Programming Languages and Their Execution Environments for Spectre Attacks
Amir Naseredini, Stefan Gast, Martin Schwarzl +5
In this paper, we analyze the security of programming languages and their execution environments (compilers and interpreters) with respect to Spectre attacks. The analysis shows th…
Remote Memory-Deduplication Attacks
Martin Schwarzl, Erik Kraft, Moritz Lipp +1
Memory utilization can be reduced by merging identical memory blocks into copy-on-write mappings. Previous work showed that this so-called memory deduplication can be exploited in…
Practical Timing Side Channel Attacks on Memory Compression
Martin Schwarzl, Pietro Borrello, Gururaj Saileshwar +3
Compression algorithms are widely used as they save memory without losing data. However, elimination of redundant symbols and sequences in data leads to a compression side channel.…
Dynamic Process Isolation
Martin Schwarzl, Pietro Borrello, Andreas Kogler +4
In the quest for efficiency and performance, edge-computing providers eliminate isolation boundaries between tenants, such as strict process isolation, and instead let them compute…
Speculative Dereferencing of Registers:Reviving Foreshadow
Martin Schwarzl, Thomas Schuster, Michael Schwarz +1
Since 2016, multiple microarchitectural attacks have exploited an effect that is attributed to prefetching. These works observe that certain user-space operations can fetch kernel…
NetSpectre: Read Arbitrary Memory over Network
Michael Schwarz, Martin Schwarzl, Moritz Lipp +1
In this paper, we present NetSpectre, a generic remote Spectre variant 1 attack. For this purpose, we demonstrate the first access-driven remote Evict+Reload cache attack over netw…
