GLitch, our JS-based Rowhammer exploit that takes advantage of GPU acceleration to trigger bit flips and get control over the Firefox browser on Android made it to the news. After respecting the 90 days disclosure policy we finally went live on May 3 releasing all the details of our attack.
The research got quite some interest from the security community on Twitter and it got covered in two detailed articles on Wired and ArsTechnica. After this, it got picked up by other news outlets such as Decipher, Tweakers, The Hacker News and others.
While the great interest for the research people did not really like the demo video. The reason is attributed to the background music.
Oh well… ¯\_(ツ)_/¯
This year, VUSec had 2 papers accepted at USENIX Security ’18: Malicious Management Unit (how to use the MMU to mount indirect cache attacks and bypass software-based defenses) and TLBleed (how to mount TLB side-channel attacks across threads and leak fine-grained information).
Network infrastructure attacks are a growing threat, and are addressed by a budding VUSec research project.
KPN recently published the fifth European Cyber Security Perspectives – edition 2018. It features an article detailing an early version of an active research project of VUsec, called Packet Origin Fidelity (POF), a detection method of network infrastructure attacks.

We analyzed the election software that is used, and has been used for years, in all Dutch elections. Our conclusion: this software is very vulnerable.
On the 13th of March, Herbert Bos appeared on RTL Nieuws to summarize these findings. He is on briefly after 7 seconds, and then again at 3m17s (also with Sebastian, Marco and Sanjay, who did the heavy lifting for the analysis, together with Andrei).
Surprisingly, Minister Ollongren does not think there is a problem, even though we show vulnerabilities as bad as integer overflows that allow attackers to manipulate overall results even from compromised local polling stations.
The news broadcast, our analysis, and the independent analysis by Sijmen Ruwhof, did lead to questions from the parliament, and some members of parliament explicitly echoed Herbert’s analysis. The issue was also reported in most newspapers and on Tweakers.
At ICTOPEN 2018, the Dutch Cyber Security best Research Papers (DCSRP) Award was awarded to AnC. Ben Gras went there to give a talk as one of the five nominees and – the jury of Prof. Dr. Konrad Rieck, Prof. Evangelos Markatos and Dr. Richard Clayton had decided – receive the award.

Or: if you can’t do the time, don’t do the crime
Several days ago, we released a technical report entitled Benchmarking Crimes: An Emerging Threat in Systems Security. The paper was intended for publication at a security conference but was rejected at multiple venues. To let our work be a supporting piece of evidence and analysis for the community to build on, we share our work with the community as a technical report, and we publish it on Arxiv.org.
The results are as revealing as they are damning: we formulate 22 different benchmarking crimes, each of which violates the results of a benchmark in a minor or major fashion. We survey 50 different systems security defense papers. We include papers published by this group in that selection. To gauge reliability, the survey is performed twice – we let two independent readers perform this survey. Their findings are consistent: in this wide study of accepted papers at top systems security venues, all papers had committed benchmarking crimes in some number and degree of egregiousness.
Most of these are recent papers (2015), but a significant fraction are from 2010. This longitudinal component of the study tells us that not only are benchmarking crimes widespread, but also no better in modern papers than in older ones.
This raises the question of how we can trust benchmarks in research results. We hope our work will contribute to an improvement in this situation.
The Register has coverage.
There has been significant media coverage over the CPU flaws known as meltdown and spectre. In the wake of one of our researchers, using only public information and speculation, reproducing the bug before the embargo got lifted, the vusec group has been asked to comment in several pieces, including tweakers.net, wired.com, volkskrant.nl, nos.nl, HBO Vice news tonight (video), news.com.au.
Recently (announcement here), Kaveh and Ben gave a talk at Hardwear.io about trusting the abstractions we think of when we program applications and kernels. We combine the very different Flip Feng Shui (rogue writing) and AnC (ASLR side channel leaking secrets) projects into a single assumptions-challenging talk.
Again, recorded talk here.
Drammer won first 2017 CSAW prize in the category Applied Research Best Paper Award.
Luckily, Victor was there to receive this award on behalf of the Drammer team!
To quote the CSAW site:
Accepted papers are presented by one of the student authors in poster-format during CSAW Finals. Industry experts serving as judges evaluate the originality, relevance, and accuracy of the research.
With eligibility limited to previously published papers, this competition has a reputation for drawing some of the best doctoral security research worldwide.
vusec is proud of this academic and industry recognition.
Nucleus, our approach to compiler-agnostic function detection in binaries (EuroS&P’17) made it into Binary Ninja.
