Keep Your Android Phone Safe From Pixnapping - DTNS 5124
🕑 Added 2025-10-14 18:30:50 +0000 UTCTOM: This is the Daily Tech News for Tuesday, October 14, 2025. We tell you what you need to know, follow up on the context of those stories and help each other understand.
JENN: Today, we walk you through the Pixnapping exploit for Android, what you do and do not need to worry about, and how to avoid falling victim to it.
I’m Tom Merritt,
I’m Jenn Cutter.
TOM: Let’s start with what you need to know with the big story.
[[BIG STORY]]
[[SOLO story of the day. Basic details, monitor commentary and sound when possible.]]
Hackers can steal 2FA codes and private messages from Android phones – Ars Technica
Hackers can steal 2FA codes and private messages from Android phones : r/DailyTechNewsShow
TOM: You should always be careful what apps you install on your devices, but here's an extra reason for Android users to be careful. Thanks to lujuan73 on our subreddit for calling attention to this one.
Scientists from the University of California at Berkeley, the University of Washington, the University of California at San Diego, and Carnegie Mellon University presented a paper this week at the 32nd ACM Conference on Computer and Communications Security. The paper is called "Pixnapping: Bringing Pixel Stealing out of the Stone Age."
The team's exploit requires the victim to install a malicious app. So that's your first line of defense. Don't install a malicious app. Sounds easy, but of course, if people didn't get tricked into installing malicious apps all the time, this wouldn't be much of a concern.
Once installed, the app that takes advantage of the Pixnapping exploit can read any data displayed on the screen without needing special system permissions.
It does this by invoking Android programming interfaces that cause the targeted app to send sensitive information, say a multifactor code, into Android's rendering pipeline to be displayed on screen. The app then runs graphical operations on the pixels on screen (like drawing a transparent piece of content over the other content) and exploits a side channel in the GPU, usually the known GPU.zip side channel. To oversimplify, the time it takes for a frame to be rendered on the screen behind the transparent image, can be used to deduce whether a pixel is white or not. The app can use that information to map pixels to letters, numbers, or shapes, thus letting it deduce what information the app sent.
The attack takes time, so had to be refined to work in the 30 seconds in which a multifactor code is shown on screen before it changes. They were able to do this on the Pixels but not the Galaxy S25.
Obfuscated or hidden information that is not displayed on screen cannot be accessed.
The exploit works on the Google Pixel and Samsung Galaxy S25. Google released partial mitigations in the September Android security bulletin, but a modified version of the exploit can still work. Google says further mitigations are coming in the December Android security bulletin. No in-the-wild exploits have been discovered.

Nvidia to Start Selling $3,999 DGX Spark Mini PC This Week | PCMag
NVIDIA starts selling its $3,999 DGX Spark AI developer PC
Nvidia unveils its vision for gigawatt 'AI factories' based on its Vera Rubin architecture – SiliconANGLE
Tom: At the 2025 OCP Global Summit in San Jose, Nvidia said it is donating its Vera Rubin NVL144 architecture to the Open Compute Project as an open standard. It is a more power-efficient rack server architecture designed to support the Vera Rubin GPUs coming in 2027.
And while we're talking about Nvidia, the company will begin selling its DGX Spark desktop (aka Project DIGITS) on October 15th. The $3,999 desktop 2.6-pound PC runs Nvidia's DGX OS, a custom version of Ubuntu. It has a GB10 super chip, which combines a 20-core Grace CPU with a Blackwell GPU and 128GB of LPDDR5x memory. That and custom software will let scientists run powerful models locally. Versions of the desktop from other vendors like Dell, HP, Lenovo and ASUS were shown at Computex, and should be coming soon. Nvidia is also working on a model with a GB300 Grace Blackwell Ultra Desktop Superchip, with 20 petaflops of performance and 784GB of unified system memory.
Microsoft debuts its first in-house AI image generator
JENN: Microsoft debuted its first in-house image generator, called MAI-Image-1. It specialises in generating photorealistic images with natural lighting and landscapes. The model is being tested on LMArena, with plans to roll out to Copilot and Bing Image Creator soon.

Oracle, AMD Partner on New AI Chip Deal – WSJ
TOM: OpenAI announced Monday that it has partnered with Broadcom for 10 gigawatts worth of custom-designed AI accelerator racks that will be deployed to OpenAI data centers and partner data centers from 2026 through 2029. Since the beginning of September, OpenAI signed deals for 6 Gigawatts of chips from AMD, 10 Gigawatts from Nvidia, and an infrastructure deal with Oracle. Deployments are to begin in the second half of 2026 as well. OpenAI is expected to have 2GW of capacity by the end of this year, but these deals are part of a goal to reach 250GW of capacity in the next 8 years. That would cost $10 trillion. OpenAI is expected to make $13 billion in revenue this year. Meanwhile, AMD is partnering with Oracle to deploy 50,000 MI450 chips in Oracle's data centers by Q3 next year.
Satellites found exposing unencrypted data, including phone calls and some military comms | TechCrunch
T-Mobile customer call and text data captured from satellite comms
JENN: Scientists at UC San Diego and the University of Maryland discovered that by using an $800 off-the-shelf satellite receiver, they could monitor unencrypted data from satellites used for routing voice calls, text messages, and internet traffic, including WiFi from airplanes. It also included communications with critical infrastructure like energy and water. The data was in an obscure format, which they needed three years to consistently decode. The scientists alerted providers, including AT&T and T-Mobile, which have since encrypted the traffic, though not everyone they contacted has done so.
Supreme Court rejects Grindr liability case
TOM: The US Supreme Court has declined to hear appeals to a second case that challenged Section 230 safe harbor protections for internet companies. Previously, it declined to hear a case holding Meta accountable for the radicalization of a mass shooter. This time, it declined to hear an appeal holding a dating app accountable for connecting a minor with adults who were later convicted of sex crimes against the minor. In both cases, lower courts ruled that the platform was not responsible for the conduct of its users.

[[HELPING EACH OTHER UNDERSTAND]]
[[Short missives from people with experience. Could be written email or pre-recorded from the person.]]
JENN: We end every episode of DTNS with some shared wisdom. Today Rob has some thoughts on AI helping productivity.
TOM: Responding to Friday’s discussion on AI productivity, Rob Bugslife commented:
With the news items today, the stuff Jenn mentioned and that I have seen at my own job, I'm not sure I can trust any of the reports of "efficiencies gain" when being self report by companies. When employees are told to find ways to use these tools and report back on gained efficiencies, they will find ways to at least appear to be following orders cause they don't want to lose their jobs. Which means to mean a lot of that data in the future may be artificially boosted.
From my own experience there are no doubt benefits, but I would be lying if I said it added more than 15% maybe 20% efficiency for some tasks, definitely not to everything.
Keep sharing and thanks keeping everything levelheaded.
