New research is able to recover sound waves in a room by observing minute changes in the room’s light bulbs. This technique works from a distance, even from a building across the street through a window. Details: In an experiment using three different telescopes with different lens diameters from a distance of 25 meters (a … Read More “Eavesdropping on Sound Using Variations in Light Bulbs” »
New research on using specially crafted inputs to slow down machine-learning neural network systems: Sponge Examples: Energy-Latency Attacks on Neural Networks shows how to find adversarial examples that cause a DNN to burn more energy, take more time, or both. They affect a wide range of DNN applications, from image recognition to natural language processing … Read More “Availability Attacks against Neural Networks” »
New research: “Security Analysis of the Democracy Live Online Voting System“: Abstract: Democracy Live’s OmniBallot platform is a web-based system for blank ballot delivery, ballot marking, and (optionally) online voting. Three states — Delaware, West Virginia, and New Jersey — recently announced that they will allow certain voters to cast votes online using OmniBallot, but, … Read More “Security Analysis of the Democracy Live Online Voting System” »
I just published a new paper with Karen Levy of Cornell: “Privacy Threats in Intimate Relationships.” Abstract: This article provides an overview of intimate threats: a class of privacy threats that can arise within our families, romantic partnerships, close friendships, and caregiving relationships. Many common assumptions about privacy are upended in the context of these … Read More “New Research: “Privacy Threats in Intimate Relationships”” »
This study shows that most people don’t change their passwords after a breach, and if they do they change it to a weaker password. Abstract: To protect against misuse of passwords compromised in a breach, consumers should promptly change affected passwords and any similar passwords on other accounts. Ideally, affected companies should strongly encourage this … Read More “Password Changing After a Breach” »
This paper describes a SIGINT and code-breaking alliance between Denmark, Sweden, Germany, the Netherlands and France called Maximator: Abstract: This article is first to report on the secret European five-partner sigint alliance Maximator that started in the late 1970s. It discloses the name Maximator and provides documentary evidence. The five members of this European alliance … Read More “Denmark, Sweden, Germany, the Netherlands and France SIGINT Alliance” »
MIT researchers have built a system that fools natural-language processing systems by swapping words with synonyms: The software, developed by a team at MIT, looks for the words in a sentence that are most important to an NLP classifier and replaces them with a synonym that a human would find natural. For example, changing the … Read More “Fooling NLP Systems Through Word Swapping” »
They can communicate using bioluminescent flashes: New research published this week in Proceedings of the National Academy of Sciences presents evidence for a previously unknown semantic-like ability in Humboldt squid. What’s more, these squid can enhance the visibility of their skin patterns by using their bodies as a kind of backlight, which may allow them … Read More “Friday Squid Blogging: On Squid Communication” »
I previously wrote about hacking voice assistants with lasers. Turns you can do much the same thing with ultrasonic waves: Voice assistants — the demo targeted Siri, Google Assistant, and Bixby — are designed to respond when they detect the owner’s voice after noticing a trigger phrase such as ‘Ok, Google’. Ultimately, commands are just … Read More “Hacking Voice Assistants with Ultrasonic Waves” »
This paper describes the flaws in the Voatz Internet voting app: “The Ballot is Busted Before the Blockchain: A Security Analysis of Voatz, the First Internet Voting Application Used in U.S. Federal Elections.” Abstract: In the 2018 midterm elections, West Virginia became the first state in the U.S. to allow select voters to cast their … Read More “Voatz Internet Voting App Is Insecure” »
