Hasta La Gadget!

From Hollywood strikes to digital portraits, AI’s potential to steal creatives’ work and how to stop it has dominated the tech conversation in 2023. The latest effort to protect artists and their creations is Nightshade, a tool allowing artists to add undetectable pixels into their work that could corrupt an AI’s training data, the MIT Technology Review reports. Nightshade’s creation comes as major companies like OpenAI and Meta face lawsuits for copyright infringement and stealing personal works without compensation.

University of Chicago professor Ben Zhao and his team created Nightshade, which is currently being peer reviewed, in an effort to put some of the power back in artists’ hands. They tested it on recent Stable Diffusion models and an AI they personally built from scratch.

Nightshade essentially works as a poison, altering how a machine-learning model produces content and what that finished product looks like. For example, it could make an AI system interpret a prompt for a handbag as a toaster or show an image of a cat instead of the requested dog (the same goes for similar prompts like puppy or wolf).

Nightshade follows Zhao and his team’s August release of a tool called Glaze, which also subtly alters a work of art’s pixels but it makes AI systems detect the initial image as entirely different than it is. An artist who wants to protect their work can upload it to Glaze and opt in to using Nightshade. 

Damaging technology like Nightshade could go a long way towards encouraging AI’s major players to request and compensate artists’ work properly (it seems like a better alternative to having your system rewired). Companies looking to remove the poison would likely need to locate every piece of corrupt data, a challenging task. Zhao cautions that some individuals might attempt to use the tool for evil purposes but that any real damage would require thousands of corrupted works.

GM has announced that it will pay $1,400 to owners of 2020-2022 Bolt EVs and EUVs who endured a recall that limited range to 80 percent for a significant period of time, Electrek has reported. It’s effectively an upfront payment to customers as part of an expected class action settlement. 

“GM is announcing a compensation program for 2020-22 Bolt EV/EUV owners upon installation of the final advanced diagnostic software as part of the original battery recall,” a spokesperson wrote in a statement. “Owners are eligible to receive a $1,400 Visa eReward card upon installation. This applies to Bolt EV/EUV owners in the US only. We’re grateful to our customers for their patience and understanding.”

Owners must install a “software final remedy” by December 31, 2023 and sign a legal release — those who decline will have to wait for the class action lawsuit to play out. If the settlement ends up being more than $1,400, those who accept the payment will still receive the difference.

It seems like Chevy’s Bolt EVs (and larger EUVs that came along in 2021) have never not had problems with their batteries. The 2017-2019 models had serious defects that could cause fires, forcing GM to recall them and install special software, reducing maximum charge levels to 90 percent. 

The 2020-2022 models affected by the lawsuit used new battery chemistry with a different issue that could also cause a fire when the car was fully, or nearly fully charged. GM issued a recall for those models as well, installing diagnostic software that would reduce maximum charging levels to 80 percent (cutting range from about 259 miles to 207 miles). The software will eventually either warn customers that their battery pack needs to be replaced, or automatically return the maximum charge to 100 percent. 

The problem is, the vehicles needed to reach 6,200 miles of use before the final assessment. That could be years for some buyers, and GM mandated that owners complete the diagnostic by March 2025 in order to qualify for an extended warranty or replacement battery, if needed. 

GM announced earlier this year that it was discontinuing the Bolt EV amid the company’s shift to the Ultium platform, possibly because it felt the name had been sullied by the battery issues. Following an outcry, though, it backtracked and said that a next-gen Bolt was in the works — showing that people still liked what the Bolt stood for (a practical, cheap EV with decent range) despite the recalls. 

Presumably, any potential settlement would cover owners who effectively lost the full and expected use of their vehicle during the period. If you’re part of the recall, you should receive a letter soon with more information and a unique PIN to access their site — more information is available here.

Amazon, the biggest e-commerce website in most countries, now supports passkeys. That gives users access to the new login solution that’s considered more secure than passwords, allowing them to access their account using the biometrics or PIN they use to unlock their devices. The company started rolling out the capability a few days ago but has only just announced the feature, which is now available on browsers and is gradually making its way to all users accessing Amazon through its iOS app. Passkey support is also “coming soon” to Amazon’s Android application. 

Passkeys are resistant to phishing, the effects of data leaks or social engineering, because there are no passwords to steal or give away. Instead, the technology uses cryptographic pairs, one of which is a public key saved on a particular service’s servers, while the other one remains private and is securely saved to a user’s device. These pairs are unique for every service, and they must match for someone to be able to log in. It’s also a lot less involved than two-factor authentication, though for some reason, Amazon will not automatically switch it off for those who turn on passkey support. 

In its FAQs, Amazon says that those who have two-factor switched on will still need to verify their identities with a one-time code even after they activate the new login option. It’s unclear if users will no longer have to key in two-factor codes after their initial login with a passkey, but upon trying it out, we weren’t asked for one the next time we signed in. To switch on passkey login, users only need to go to Login & Security under Your Account on Amazon and then choose “Set up” next to the new Passkeys option.
