An exploit allows messages and additional data to be sent across Apple's Find My network, according to the findings of a security researcher.
Security researcher Fabian Bräunlein has found a way to leverage Apple's Find My network to function as a generic data transfer mechanism, allowing non-internet-connected devices to upload arbitrary data by using nearby Apple devices to upload the data for them.
The Find My network uses the entire base of active iOS devices to act as nodes to transfer location data. Bräunlein explained in an extensive blog post that it is possible to emulate the way in which an AirTag connects to the Find My network and broadcasts its location. The AirTag sends its location via an encrypted broadcast, so when this data is replaced with a message, it is concealed by the broadcast's encryption.
Bräunlein's practical demonstration showed how short strings of text could be sent from a microcontroller running custom firmware over the Find My network. The text was received via a custom Mac app to decode and display the uploaded data.
It is not immediately clear if this Find My network exploit could be used maliciously or what useful purposes it may serve. Nonetheless, it seems that it could be difficult for Apple to prevent this unintended use due to the privacy-focused and end-to-end encrypted nature of the system.
For more information, see Bräunlein's full blog post, which explains in detail the entire technical process behind passing arbitrary data through the Find My network.

Barclays analyst Tom O'Malley and his colleagues recently traveled to Asia to meet with various electronics manufacturers and suppliers. In a research note this week, outlining key takeaways from the trip, the analysts said they have "confirmed" that a fourth-generation iPhone SE with an Apple-designed 5G modem is slated to launch towards the end of the first quarter next year. In line with previo...

Apple released the AirTag in April 2021, so it is now three over and a half years old. While the AirTag has not received any hardware updates since then, a new version of the item tracking accessory is rumored to be in development.
Below, we recap rumors about a second-generation AirTag.
Timing
Apple is aiming to release a new AirTag in mid-2025, according to Bloomberg's Mark Gurman....

Apple today released iOS 18.1.1 and iPadOS 18.1.1, minor updates to the iOS 18 and iPadOS 18 operating systems that debuted earlier in September. iOS 18.1.1 and iPadOS 18.1.1 come three weeks after the launch of iOS 18.1.
The new software can be downloaded on eligible iPhones and iPads over-the-air by going to Settings > General > Software Update. Apple has also released iOS 17.7.2 for...

While the Logitech MX Master 3 is a terrific mouse for the Mac, reports claiming that Apple CEO Tim Cook prefers that mouse over the Magic Mouse are false.
The Wall Street Journal last month published an interview with Cook, in which he said he uses every Apple product every day. Soon after, The Verge's Wes Davis attempted to replicate using every Apple product in a single day. During that...

In a research note with Hong Kong-based investment bank Haitong today, obtained by MacRumors, Apple analyst Jeff Pu said he agrees with a recent rumor claiming that the so-called "iPhone 17 Air" will be around 6mm thick.
"We agreed with the recent chatter of an 6mm thickness ultra-slim design of the iPhone 17 Slim model," he wrote.
If that measurement proves to be accurate, there would be ...

The iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1 updates that Apple released today address JavaScriptCore and WebKit vulnerabilities that Apple says have been actively exploited on some devices.
With the JavaScriptCore vulnerability, processing maliciously crafted web content could lead to arbitrary code execution. The WebKit vulnerability had the same issue with maliciously crafted...

Apple has partnered with select merchants to offer Apple Card users three percent Daily Cash back on their purchases, and two new companies were added to the partner list today. When purchasing goods and services from Booking.com and ChargePoint, Apple Card users will now get more cash back.
Booking.com is a site for reserving flights, cars, cruises, and hotels, while ChargePoint sells...
The first thought that comes to mind is someone installing a compromised IoT device that gains legitimate access to their network and then uses the Find My network to funnel data out of the network, bypassing any firewall rules that prevent the IoT device from communicating with the Internet at large.
It's the type of thing you'd see in a heist or spy movie to try and snag someone's password.
Another “IF YOU SET EVERYTHING UP JUUUUUUUUUST RIGHT, YOU CAN DO A THING!” from a security researcher. AirTags is the security gift that keeps on giving. Next week, “We’ve been able to determine that if you accelerate an AirTag at just the right speed towards a target that’s not trying to dodge and is totally aware and ok that you’re throwing it (though accelerate sounds cooler) YOU MAY BE ABLE TO HIT THEM!”
This could be used for some kind of Denial of Service Attack, couldn't it?
You set up a server that's just spamming the Find My network, then all the Apple devices are constantly bouncing these spam messages around. They may end up drowning out legitimate Find My network messages.
Waiting for someone to show a hack that executed the following steps: 1) uses forgot password 2) clicks try another device for access code pin 3) has a hamster run in a wheel to disrupt radio waves transmitting the secret pin 4) said wheel traps the secret pin and translated via a sudoku puzzle to the hacker 5) hacker inlists a millennial to decrypt the puzzle 6) millennial asks for gluten free juice cleanser for payment 7) hacker gets in!

From the source:
With the public key validity check implemented, everything worked flawlessly. While I didn't do extensive performance testing and measurements, here are some estimates:
The sending rate on the microcontroller is currently ~3 bytes/second. Higher speeds could be achieved e.g. simply by caching the encoding results or by encoding one byte per advertisement In my tests, the receiving rate was limited by slow Mac hardware. Retrieving 16 bytes within one request takes ~5 seconds The latency is usually between 1 and 60 minutes depending on how many devices are around and other random factors.
