After a long embargo period of 9 months we made our paper RIDL: Rogue In-Flight Data Load available to the general public. RIDL introduces a new class of speculative execution attacks that can leak any “in-flight” data available in the CPU.
More information (including some nice demo videos) are available at https://mdsattacks.com. We have also released a tool that you can use to see how vulnerable your computer is to different speculative execution attacks.
We have shared TLBleed with several operating system projects, in order for them to be able to implement mitigations if desired. As a result of seeing TLBleed, OpenBSD decided to disable /msg99141.html">Hyperthreading by default. This has prompted some speculation that TLBleed is a spectre-like attack, but that is not the case. OpenBSD also realizes the exact impact of TLBleed. There has been significant news coverage: TheRegister (and this one), ArsTechnica, bleepingcomputer, ZDnet, Techrepublic, TechTarget, ITwire, tweakers, and a personal favorite, the SecurityNow Podcast episode 669 (mp3, show notes, youtube).
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)_/¯
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.
Prof. Herbert Bos, Prof. Michel van Eeten, and Prof. Bart Jacobs on the 24th released a joint Dutch statement and proposal on the inadequacy of academic cybersecurity funding in The Netherlands. Funding that is up to 50x higher in neighboring countries is causing a drain of talented researchers away from The Netherlands.
Cybersecurity Investment Proposal
The proposal calls for the development of a three-pronged strategy to maintain the high academic standard of Dutch research organizations, funded by in total a budget of €100 million over 10 years, in a combination of public and private investment.
€40M (public): fund open tenders for non-permanent PhD and postdoc projects, where both pure-CS and interdisciplinary proposals will be considered. Examples might be legal, medical and organizational fields.
€20M (public): a budget of €2M/year for which universities may apply to either (a) hire permanent staff for a newly appointed cybersecurity professor; or (b) retain staff, done by a cybersecurity professor with at least 5 years proven record, to establish areas of new research.
€40M (private): The establishment of a pool of inter-organizational cybersecurity experts. The organizations will be a combination of research, government and industrial organizations that host the members. These members will then share knowledge, deepen knowledge (by following an external or industrial PhD program), and provide operational expertise in emergencies.
Coverage
This proposal was covered in Computable last week and Prof. Bos was a guest on BNR News Radio at 06:00 AM this morning for discussion.
Today we announce ASLR^Cache, a MMU sidechannel exploiting a micro-architectural property of all modern CPU models. This signal is even visible from Javascript and breaks ASLR in sandboxed environments. The name ASLR^Cache (or simply AnC) is a reference to the fact that ASLR and CPU caches are mutually exclusive on modern architectures. For more information, please see our AnC project page.
