Octopus and squid genes are weird. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my blog posting guidelines here. Powered by WPeMatico
Researchers have demonstrated controlling touchscreens at a distance, at least in a laboratory setting: The core idea is to take advantage of the electromagnetic signals to execute basic touch events such as taps and swipes into targeted locations of the touchscreen with the goal of taking over remote control and manipulating the underlying device. The … Read More “Remotely Controlling Touchscreens” »
Interesting paper by Lennart Maschmeyer: “The Subversive Trilemma: Why Cyber Operations Fall Short of Expectations“: Abstract: Although cyber conflict has existed for thirty years, the strategic utility of cyber operations remains unclear. Many expect cyber operations to provide independent utility in both warfare and low-intensity competition. Underlying these expectations are broadly shared assumptions that information … Read More “The Limits of Cyber Operations in Wartime” »
Yet another adversarial ML attack: Most deep neural networks are trained by stochastic gradient descent. Now “stochastic” is a fancy Greek word for “random”; it means that the training data are fed into the model in random order. So what happens if the bad guys can cause the order to be not random? You guessed … Read More “Manipulating Machine-Learning Systems through the Order of the Training Data” »
A surprising number of websites include JavaScript keyloggers that collect everything you type as you type it, not just when you submit a form. Researchers from KU Leuven, Radboud University, and University of Lausanne crawled and analyzed the top 100,000 websites, looking at scenarios in which a user is visiting a site while in the … Read More “Websites that Collect Your Data as You Type” »
Video of oval squid (Sepioteuthis lessoniana) changing color in reaction to their background. The research paper claims this is the first time this has been documented. As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered. Read my blog posting guidelines here.

Researchers are using the reflection of the smartphone in the pupils of faces taken as selfies to infer information about how the phone is being used: For now, the research is focusing on six different ways a user can hold a device like a smartphone: with both hands, just the left, or just the right … Read More “Using Pupil Reflection in Smartphone Camera Selfies” »
New research: “Are You Really Muted?: A Privacy Analysis of Mute Buttons in Video Conferencing Apps“: Abstract: In the post-pandemic era, video conferencing apps (VCAs) have converted previously private spaces — bedrooms, living rooms, and kitchens — into semi-public extensions of the office. And for the most part, users have accepted these apps in their … Read More “Video Conferencing Apps Sometimes Ignore the Mute Button” »
Interesting: Drawing inspiration from cephalopod skin, engineers at the University of California, Irvine invented an adaptive composite material that can insulate beverage cups, restaurant to-go bags, parcel boxes and even shipping containers. […] “The metal islands in our composite material are next to one another when the material is relaxed and become separated when the … Read More “Friday Squid Blogging: Squid Skin–Inspired Insulating Material” »
New research on the changing migration of the Doryteuthis opalescens as a result of climate change. News article: Stanford researchers have solved a mystery about why a species of squid native to California has been found thriving in the Gulf of Alaska about 1,800 miles north of its expected range: climate change. As usual, you … Read More “Friday Squid Blogging: Squid Migration and Climate Change” »
