EFF Teams Up With AV Comparatives to Test Android Stalkerware Detection by Major Antivirus Apps
EFF has, for many years, raised the alarm about the proliferation of stalkerware—commercially-available apps designed to be installed covertly on another person’s device and exfiltrate data from that device without their knowledge. In particular, we have urged the makers of anti-virus products for Android phones to improve their detection of stalkerware and call it out explicitly to users when it is found. In 2020 and 2021, AV Comparatives ran tests to see how well the most popular anti-virus […]

OpenAI’s new GPT-5.2 model takes on Google’s Gemini 3
As expected and following multiple reports, OpenAI officially announced the GPT-5.2 model. For those unaware, it’s a product that the company fast-tracked out of the heat it’s facing from the success of the latest models from Google and Anthropic. Not to forget, the GPT-5.2 is OpenAI’s second biggest update since the company officially launched GPT-5 in August. GPT-5.2 is here with improved raw performance results In the announcement, OpenAI describes GPT-5.2 as its “most capable model series yet […]

EFF to Arizona Federal Court: Protect Public School Students from Surveillance and Punishment for Off-Campus Speech
Legal Intern Alexandra Rhodes contributed to this blog post. EFF filed an amicus brief urging the Arizona District Court to protect public school students’ freedom of speech and privacy by holding that the use of a school-issued laptop or email account does not categorically mean a student is “on campus.” We argued that students need private digital spaces beyond their school’s reach to speak freely, without the specter of constant school surveillance and punishment. Surveillance Software Exposed a […]

The Machine Learning “Advent Calendar” Day 5: GMM in Excel
This article introduces the Gaussian Mixture Model as a natural extension of k-Means, by improving how distance is measured through variances and the Mahalanobis distance. Instead of assigning points to clusters with hard boundaries, GMM uses probabilities learned through the Expectation–Maximization algorithm – the general form of Lloyd’s method. Using simple Excel formulas, we implement EM step by step in 1D and 2D, and we visualise how the Gaussian curves or ellipses move during training. The means shift, […]

Simpler models can outperform deep learning at climate prediction
Environmental scientists are increasingly using enormous artificial intelligence models to make predictions about changes in weather and climate, but a new study by MIT researchers shows that bigger models are not always better. The team demonstrates that, in certain climate scenarios, much simpler, physics-based models can generate more accurate predictions than state-of-the-art deep-learning models. Their analysis also reveals that a benchmarking technique commonly used to evaluate machine-learning techniques for climate predictions can be distorted by natural variations in […]
