Zoom Vulnerability

The Zoom conferencing app has a vulnerability that allows someone to remotely take over the computer’s camera. It’s a bad vulnerability, made worse by the fact that it remains even if you uninstall the Zoom app: This vulnerability allows any website to forcibly join a user to a Zoom call, with their video camera activated, without the user’s permission. On… Continue reading Zoom Vulnerability

Newly reported flaws in cameras, locks add to scrutiny of smart-home security

Homeowners trying to protect their property with surveillance cameras and smart locks may have actually made their households more vulnerable, according to security flaws unveiled by separate teams of researchers Tuesday. The Netgear Arlo system, which the company says streams more than 100 million videos every day, and certain types of Zipato smart hubs, which can lock or unlock doors, are affected by security flaws detailed in unrelated announcements from Tenable and researchers Chase Dardaman and Jason Wheeler, respectively. The discoveries again demonstrate how the same technology that promises to make life more convenient and secure also can put consumers at risk. Patches are available for both vulnerabilities, and hackers would need physical access in both cases to carry out attacks. The weakness in the Arlo devices could allow malicious outsiders to take control of all the cameras connected to a single hub, at which point they could disable the video […]

Maybe a bored guard watched a dozen different screens, scanning for something interesting. In either case, the video was only stored for a few days because storage was expensive. Increasingly, none of that is true. Recent… Continue reading Computers and Video Surveillance

Video Surveillance by Computer

The ACLU’s Jay Stanley has just published a fantastic report: "The Dawn of Robot Surveillance" (blog post here) Basically, it lays out a future of ubiquitous video cameras watched by increasingly sophisticated video analytics software, and discusses the potential harms to society. I’m not going to excerpt a piece, because you really need to read the whole thing…. Continue reading Video Surveillance by Computer

iOS Shortcut for Recording the Police

"Hey Siri; I’m getting pulled over" can be a shortcut: Once the shortcut is installed and configured, you just have to say, for example, "Hey Siri, I’m getting pulled over." Then the program pauses music you may be playing, turns down the brightness on the iPhone, and turns on "do not disturb" mode. It also sends a quick text to… Continue reading iOS Shortcut for Recording the Police
