Fascinating research: “Generating Master Faces for Dictionary Attacks with a Network-Assisted Latent Space Evolution.” Abstract: A master face is a face image that passes face-based identity-authentication for a large portion of the population. These faces can be used to impersonate, with a high probability of success, any user, without having access to any user-information. We … Read More “Using “Master Faces” to Bypass Face-Recognition Authenticating Systems” »

New paper: “Encrypted Cloud Photo Storage Using Google Photos“: Abstract: Cloud photo services are widely used for persistent, convenient, and often free photo storage, which is especially useful for mobile devices. As users store more and more photos in the cloud, significant privacy concerns arise because even a single compromise of a user’s credentials give … Read More “Storing Encrypted Photos in Google’s Cloud” »

Interesting research: “EvilModel: Hiding Malware Inside of Neural Network Models”. Abstract: Delivering malware covertly and detection-evadingly is critical to advanced malware campaigns. In this paper, we present a method that delivers malware covertly and detection-evadingly through neural network models. Neural network models are poorly explainable and have a good generalization ability. By embedding malware into … Read More “Hiding Malware in ML Models” »

As ransomware becomes more common, I’m seeing more discussions about the ethics of paying the ransom. Here’s one more contribution to that issue: a research paper that the insurance industry is hurting more than it’s helping. However, the most pressing challenge currently facing the industry is ransomware. Although it is a societal problem, cyber insurers … Read More “Insurance and Ransomware” »

General Packet Radio Service (GPRS) is a mobile data standard that was widely used in the early 2000s. The first encryption algorithm for that standard was GEA-1, a stream cipher built on three linear-feedback shift registers and a non-linear combining function. Although the algorithm has a 64-bit key, the effective key length is only 40 … Read More “Intentional Flaw in GPRS Encryption Algorithm GEA-1” »

Detecting Deepfake Picture Editing

“Markpainting” is a clever technique to watermark photos in such a way that makes it easier to detect ML-based manipulation: An image owner can modify their image in subtle ways which are not themselves very visible, but will sabotage any attempt to inpaint it by adding visible information determined in advance by the markpainter. One … Read More “Detecting Deepfake Picture Editing” »

Henry Farrell and I published a paper on fixing American democracy: “Rechanneling Beliefs: How Information Flows Hinder or Help Democracy.” It’s much easier for democratic stability to break down than most people realize, but this doesn’t mean we must despair over the future. It’s possible, though very difficult, to back away from our current situation … Read More “Information Flows and Democracy” »

There’s new research that demonstrates security vulnerabilities in all of the AMD and Intel chips with micro-op caches, including the ones that were specifically engineered to be resistant to the Spectre/Meltdown attacks of three years ago. Details: The new line of attacks exploits the micro-op cache: an on-chip structure that speeds up computing by storing … Read More “New Spectre-Like Attacks” »
