Installing printers can be a pain. Installing printers on Linux results in an even bigger pain. Installing printers with wrong and crappy drivers and no open-source alternative is an endless amount of pain.
Kudos to Canon for hitting the trifecta.
So I've set out to get the drivers for my …
read moreSoftware contains bugs and some bugs are exploitable. Mitigations protect our systems in the presence of these vulnerabilities, often stopping the program when detecting a security violation. The alternative is to discover bugs during development and fixing them in the code. Despite massive efforts, finding and reproducing bugs is incredibly …
read moreSide channel attacks such as Spectre or Meltdown allow data leakage from an unwilling process. Until now, transient execution side channel attacks primarily leveraged cache-based side channels to leak information. The very purpose of a cache, that of providing faster access to a subset of data, enables information leakage. While …
read moreOn one hand, GPUs expose broad functionality for graphics and machine learning workloads, on the other hand, this functionality may be exploited due to large amounts of unvetted code, complex functionality, and the information gap between user-space application, kernel, and the auxiliary GPU. We introduce a novel framework that allows …
read moreWith the rise of strong control-flow defenses such as Control-Flow Integrity (CFI), attackers will increasingly resort to data-only attacks that can be equally powerful. Earlier research demonstrated that data-only attacks can be as devastating as control-flow hijacking attacks. So far, constructing data-only attacks was cumbersome and required deep manual analysis …
read moreThis post started out of the need to provide a little more clarification after a long and heated discussions on Twitter (initial discussion and follow up) about the origins of Control-Flow Integrity (CFI), the contributions of academia, and the precision, performance, and compatibility of different existing implementations.
CFI is a …
read moreAssuming you have given everything to write the best and most beautiful paper you can ever create, it is obvious that the reviewers must see your points and therefore write you a favorable review with a recommendation of strong accept. Unfortunately, this is not always the case and reviewers may …
read moreAfter serious advertising of the NSF TTP program at several conferences throughout last year, I've decided to submit to the NSF TTP program last fall. The NSF TTP program is supposed to help transition research into practice, either by forming a company to commercialize a prototype or by developing a …
read moreProgram Committee (PC) meetings are this mysterious event where the fate of our research projects is decided based on a review of our paper submission. Especially for beginning researchers (i.e., PhD students) it is unclear how the evaluation and review process actually works. From a student's perspective, a paper …
read moreJust like every year, this year's NDSS was mid February in sunny (but not too warm) San Diego. To help cure the minimal 3 hour jetlag, I enjoyed a couple of morning runs with some of my colleagues -- if you want to get a workout done at a security conference …
