New iPhone Security Features to Protect Stolen Devices

Apple is rolling out a new “Stolen Device Protection” feature that seems well thought out:

When Stolen Device Protection is turned on, Face ID or Touch ID authentication is required for additional actions, including viewing passwords or passkeys stored in iCloud Keychain, applying for a new Apple Card, turning off Lost Mode, erasing all content and settings, using payment methods saved in Safari, and more. No passcode fallback is available in the event that the user is unable to complete Face ID or Touch ID authentication.

For especially sensitive actions, including changing the password of the Apple ID account associated with the iPhone, the feature adds a security delay on top of biometric authentication. In these cases, the user must authenticate with Face ID or Touch ID, wait one hour, and authenticate with Face ID or Touch ID again. However, Apple said there will be no delay when the iPhone is in familiar locations, such as at home or work.

Data Exfiltration Using Indirect Prompt Injection

Interesting attack on a LLM:

In Writer, users can enter a ChatGPT-like session to edit or create their documents. In this chat session, the LLM can retrieve information from sources on the web to assist users in creation of their documents. We show that attackers can prepare websites that, when a user adds them as a source, manipulate the LLM into sending private information to the attacker or perform other malicious activities.

The data theft can include documents the user has uploaded, their chat history or potentially specific private information the chat model can convince the user to divulge at the attacker’s behest.

OpenAI Is Not Training on Your Dropbox Documents—Today

There’s a rumor flying around the Internet that OpenAI is training foundation models on your Dropbox documents.

Here’s CNBC. Here’s Boing Boing. Some articles are more nuanced, but there’s still a lot of confusion.

It seems not to be true. Dropbox isn’t sharing all of your documents with OpenAI. But here’s the problem: we don’t trust OpenAI. We don’t trust tech corporations. And—to be fair—corporations in general. We have no reason to.

Simon Willison nails it in a tweet:

“OpenAI are training on every piece of data they see, even when they say they aren’t” is the new “Facebook are showing you ads based on overhearing everything you say through your phone’s microphone.”

Willison expands this in a blog post, which I strongly recommend reading in its entirety. His point is that these companies have lost our trust:

Trust is really important. Companies lying about what they do with your privacy is a very serious allegation.

A society where big companies tell blatant lies about how they are handling our data—­and get away with it without consequences­—is a very unhealthy society.

A key role of government is to prevent this from happening. If OpenAI are training on data that they said they wouldn’t train on, or if Facebook are spying on us through our phone’s microphones, they should be hauled in front of regulators and/or sued into the ground.

If we believe that they are doing this without consequence, and have been getting away with it for years, our intolerance for corporate misbehavior becomes a victim as well. We risk letting companies get away with real misconduct because we incorrectly believed in conspiracy theories.

Privacy is important, and very easily misunderstood. People both overestimate and underestimate what companies are doing, and what’s possible. This isn’t helped by the fact that AI technology means the scope of what’s possible is changing at a rate that’s hard to appreciate even if you’re deeply aware of the space.

If we want to protect our privacy, we need to understand what’s going on. More importantly, we need to be able to trust companies to honestly and clearly explain what they are doing with our data.

On a personal level we risk losing out on useful tools. How many people cancelled their Dropbox accounts in the last 48 hours? How many more turned off that AI toggle, ruling out ever evaluating if those features were useful for them or not?

And while Dropbox is not sending your data to OpenAI today, it could do so tomorrow with a simple change of its terms of service. So could your bank, or credit card company, your phone company, or any other company that owns your data. Any of the tens of thousands of data brokers could be sending your data to train AI models right now, without your knowledge or consent. (At least, in the US. Hooray for the EU and GDPR.)

Or, as Thomas Claburn wrote:

“Your info won’t be harvested for training” is the new “Your private chatter won’t be used for ads.”

These foundation models want our data. The corporations that have our data want the money. It’s only a matter of time, unless we get serious government privacy regulation.

Police Get Medical Records without a Warrant

More unconstrained surveillance:

Lawmakers noted the pharmacies’ policies for releasing medical records in a letter dated Tuesday to the Department of Health and Human Services (HHS) Secretary Xavier Becerra. The letter—signed by Sen. Ron Wyden (D-Ore.), Rep. Pramila Jayapal (D-Wash.), and Rep. Sara Jacobs (D-Calif.)—said their investigation pulled information from briefings with eight big prescription drug suppliers.

They include the seven largest pharmacy chains in the country: CVS Health, Walgreens Boots Alliance, Cigna, Optum Rx, Walmart Stores, Inc., The Kroger Company, and Rite Aid Corporation. The lawmakers also spoke with Amazon Pharmacy.

All eight of the pharmacies said they do not require law enforcement to have a warrant prior to sharing private and sensitive medical records, which can include the prescription drugs a person used or uses and their medical conditions. Instead, all the pharmacies hand over such information with nothing more than a subpoena, which can be issued by government agencies and does not require review or approval by a judge.

Three pharmacies—­CVS Health, The Kroger Company, and Rite Aid Corporation—­told lawmakers they didn’t even require their pharmacy staff to consult legal professionals before responding to law enforcement requests at pharmacy counters. According to the lawmakers, CVS, Kroger, and Rite Aid said that “their pharmacy staff face extreme pressure to immediately respond to law enforcement demands and, as such, the companies instruct their staff to process those requests in store.”

The rest of the pharmacies—­Amazon, Cigna, Optum Rx, Walmart, and Walgreens Boots Alliance­—at least require that law enforcement requests be reviewed by legal professionals before pharmacists respond. But, only Amazon said it had a policy of notifying customers of law enforcement demands for pharmacy records unless there were legal prohibitions to doing so, such as a gag order.
