RIDL featured in the media

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.

TLBleed in the news

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 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).

The full paper will be online soon.

GLitch hits the news

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 DecipherTweakers, 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)_/¯
