Invasive Israeli-founded bloatware is harvesting data from Samsung users in WANA
IronSource Expands Samsung Partnership, Launching on Samsung Mobile Devices in MENA https://www.businesswire.com/news/home/20221103005106/en/iro…es-in-MENA
Across West Asia and North Africa (WANA), growing concerns about digital surveillance have placed Israeli cybersecurity firms and their software under intense scrutiny. Among the most alarming cases is AppCloud, a pre-installed application on Samsung’s A and M series smartphones.
The bloatware cannot be uninstalled easily because it runs on the device’s operating system. Uninstalling it requires root access (the highest level of control in a computer system) of the phone to remove the AppCloud package. Its privacy policy is nowhere to be found online and opting out is not always available.
But the real concern lies in who owns AppCloud. When investigating further, we discovered that AppCloud’s privacy policy can be traced back to the controversial Israeli-founded company ironSource (now owned by the American company Unity). ironSource is notorious for its questionable practices regarding user consent and data privacy.
3D worlds created from just a few phone photos
Existing 3D scene reconstructions require a cumbersome process of precisely measuring physical spaces with LiDAR or 3D scanners, or correcting thousands of photos along with camera pose information. A research team at KAIST has overcome these limitations and introduced a technology enabling the reconstruction of 3D—from tabletop objects to outdoor scenes—with just two to three ordinary photographs.
The results, posted to the arXiv preprint server, suggest a new paradigm in which spaces captured by camera can be immediately transformed into virtual environments.
The research team led by Professor Sung-Eui Yoon from the School of Computing developed the new technology called SHARE (Shape-Ray Estimation), which can reconstruct high-quality 3D scenes using only ordinary images, without precise camera pose information.
Google backpedals on new Android developer registration rules
Google is backpedaling on its decision to introduce new identity verification rules for all developers, stating that it will also introduce accounts for limited app distribution and will allow users to install apps from unverified devs.
As announced in August, Google was planning to introduce what it called “Developer Verification” starting in 2026 to block malware spreading via sideloaded apps sourced from outside the official Google Play app store.
The new rules require that all apps must originate from developers with verified identities to be installed on certified Android devices; otherwise, their installation will be blocked.
Genetically engineered virus acts as ‘smart sponge’ to extract rare earth elements from water
Today’s high-tech electronics and green energy technologies would not function without rare earth elements (REEs). These 17 metals possess unique properties essential to creating items like the phosphors that illuminate our mobile phone displays and the powerful magnets used in electric vehicles and wind turbines. But extracting these substances from raw materials is a dirty process that relies on toxic chemicals and leaves behind polluted waste.
Now, a team of UC Berkeley-led researchers may have solved this problem—thanks to a tiny virus.
As reported in Nano Letters, the researchers genetically engineered a harmless virus to act like a “smart sponge” that grabs rare earth metals from water, and, with a gentle change in temperature and acidity (pH), releases them for collection. Their unusual, groundbreaking approach could lead to a “clean” biological alternative to traditional extraction methods for REEs and other critical elements.
Metasurfaces show promise in boosting AR image clarity and brightness
Researchers have designed and demonstrated a new optical component that could significantly enhance the brightness and image quality of augmented reality (AR) glasses. The advance brings AR glasses a step closer to becoming as commonplace and useful as today’s smartphones.
“Many of today’s AR headsets are bulky and have a short battery life with displays that are dim and hard to see, especially outdoors,” said research team leader Nick Vamivakas from the University of Rochester. “By creating a much more efficient input port for the display, our work could help make AR glasses much brighter and more power-efficient, moving them from being a niche gadget to something as light and comfortable as a regular pair of eyeglasses.”
In an article published in the journal Optical Materials Express, the researchers describe how they replaced a single waveguide in-coupler—the input port where the image enters the glass—with one featuring three specialized zones, each made of a metasurface material, to achieve improved performance.
Magnetic materials discovered by AI could reduce rare earth dependence
Researchers at the University of New Hampshire have harnessed artificial intelligence to accelerate the discovery of new functional magnetic materials, creating a searchable database of 67,573 magnetic materials, including 25 previously unrecognized compounds that remain magnetic even at high temperatures.
“By accelerating the discovery of sustainable magnetic materials, we can reduce dependence on rare earth elements, lower the cost of electric vehicles and renewable-energy systems, and strengthen the U.S. manufacturing base,” said Suman Itani, lead author and a doctoral student in physics.
The newly created database, named the Northeast Materials Database, helps to more easily explore all the magnetic materials which play a major role in the technology that powers our world: smartphones, medical devices, power generators, electric vehicles and more. But these magnets rely on expensive, imported, and increasingly difficult to obtain rare earth elements, and no new permanent magnet has been discovered from the many magnetic compounds we know exist.
Samsung Mobile Flaw Exploited as Zero-Day to Deploy LANDFALL Android Spyware
It’s assessed that the attacks involved sending via WhatsApp malicious images in the form of DNG (Digital Negative) files, with evidence of LANDFALL samples going all the way back to July 23, 2024. This is based on DNG artifacts bearing names like “WhatsApp Image 2025/02/10 at 4.54.17 PM.jpeg” and “IMG-20240723-WA0000.jpg.”
Itay Cohen, senior principal researcher at Palo Alto Networks Unit 42, told The Hacker News that they have not observed any significant functional changes between the samples from July 2024 and February 2025, when the most recent LANDFALL artifact was uploaded to VirusTotal.
LANDFALL, once installed and executed, acts as a comprehensive spy tool, capable of harvesting sensitive data, including microphone recording, location, photos, contacts, SMS, files, and call logs.
