Swatting Goes Into Politics — as Congresswoman Greene Discovered

Swatting — calling the police and pretending that a violent incident is taking place at a given address — can kill the victim

This has been a summer to remember for U.S. Congresswoman Marjorie Taylor Greene (R-Georgia). She was “swatted” twice. The first false report that brought the police to her home was Wednesday, August 23: According to the first Rome PD report, five officers responded to a call on Wednesday during the initial attempted swatting. The caller claimed that a man had been “shot five times in a bathtub” at Greene’s home, and there was a woman and possibly children still in potential danger. On the way to Greene’s house, police realized who the homeowner was, but “due to the nature of the call,” police “formed up” at a nearby intersection and made a “tactical approach.” Rome PD provided Ars with no…

New Text-to-Art Image Generator Easier to Misuse, Critics Say

Relative to DALL-E 2, it is easier to use to generate pornography, as controversial website 4Chan has recently demonstrated

Stable Diffusion, a new open source text-to-art generator (they’re coming thick and fast), dropped a couple of days ago: It has come under fire for some of its more questionable uses. Most uses have been reasonable, according to Kyle Wiggers at TechCrunch, but the problem uses give us a window into potential headaches to come: On the infamous discussion board 4chan, where the model leaked early, several threads are dedicated to AI-generated art of nude celebrities and other forms of generated pornography. Emad Mostaque, the CEO of Stability AI, called it “unfortunate” that the model leaked on 4chan and stressed that the company was working with “leading ethicists and technologies” on safety and other mechanisms around responsible release.

A Novel Trick for Detecting Deepfakes: A Sideways View

The average person doesn’t have many profile pictures so a sideways view may well blur out, revealing the fakery. But that’s just a first step…

Tech writer Martin Anderson offers a simple trick to detect deepfakes in video calls: Ask the caller to turn sideways: DeepFaceLive is a live-streaming version of the popular DeepFaceLab software, and is capable of creating alternate video identities in real-time. From more or less face-on viewpoints, most of the celebrity recreations are quite effective, and some are very convincing even at fairly acute angles – until the facial angle hits a full 90°.ry good at recreating profile views. Martin Anderson, “To Uncover a Deepfake Video Call, Ask the Caller to Turn Sideways” at Metaphysic (August 8, 2022) Then, as his examples at the site show, the possibly convincing face fuzzes out. He thinks that computer security analysts have overlooked this…
