GPUHammer: Practical Rowhammer Attacks on GPU Memory

2025-07-16

Researchers from the University of Toronto have developed GPUHammer, the first successful Rowhammer attack against GPU memory, specifically GDDR6 memory in an NVIDIA A6000 GPU. The attack uses user-level CUDA code to bypass in-DRAM defenses like TRR, inducing bit flips across all tested DRAM banks. This allows a malicious user to tamper with other users' data in shared, time-sliced environments. A proof-of-concept demonstrated an accuracy degradation attack against a victim's DNN model, reducing accuracy from 80% to 0.1% with a single bit flip. While enabling ECC mitigates the risk, it can introduce up to a 10% slowdown for ML inference workloads on the A6000.

Cell Phone OPSEC at Borders: Data Deletion and Recovery

2025-04-05

Concerns are rising about stricter electronic device checks at US borders. The author asks about securely deleting data (files, photos) from phones to prevent recovery. Does a factory reset truly erase data, or is it recoverable? This question hinges on whether the reset removes the encryption key or just the access password. The article stresses the growing need for enhanced phone security globally, given increasing risks for those opposing state power.

MIT Study: AI Chatbots Reduce Brain Activity, Impair Fact Retention

A new preprint study from MIT reveals that using AI chatbots to complete tasks actually reduces brain activity and may lead to poorer fact retention. Researchers had three groups of students write essays: one without assistance, one using a search engine, and one using GPT-4. The LLM group showed the weakest brain activity and worst knowledge retention, performing poorly on subsequent tests. The study suggests that early reliance on AI may lead to shallow encoding and impaired learning, recommending delaying AI integration until sufficient self-driven cognitive effort has occurred.

Reverse Engineering a Ski Jump: Reaching the Game's Limits

2025-08-10

Driven by childhood nostalgia, a programmer delves into the code of a retro ski-jumping game to conquer its 100-meter barrier. Rejecting tool-assisted approaches, he opts for reverse engineering, deciphering the game's binary and replay file format. By analyzing the game's physics engine, he reconstructs the jump simulation and ultimately uses a meticulously crafted replay file to achieve an astonishing 113.8-meter jump, revealing subtle discrepancies between the game's mechanics and optimal strategies.

Electric School Buses Fuel V2X Market Boom

Electric school buses are driving significant growth in the vehicle-to-everything (V2X) market, poised to double capacity to 40 megawatts by 2025, according to a new Wood Mackenzie report. Their predictable schedules, large batteries, and downtime make them ideal for V2X applications. However, challenges remain, including unclear utility interconnection processes and a lack of compensation mechanisms. While European energy companies are forming partnerships to explore V2X business models, mass adoption hinges on standardizing charging protocols and reducing hardware costs. Many 2025 passenger EVs will feature vehicle-to-load (V2L) capabilities, a stepping stone to broader AC V2X adoption.

Google strongly disagrees with and will appeal the Department of Justice's (DOJ) ruling in the search distribution lawsuit. Ahead of an April 2025 hearing, Google submitted its own remedies proposal, focusing on contracts with browser and Android device makers. The proposal aims to give browser companies and device makers more flexibility in choosing default search engines, while ensuring compliance with the court's order and avoiding harm to consumer privacy and US tech leadership. In contrast, the DOJ's proposal is seen as overly interventionist and potentially harmful to consumers and US tech competitiveness.

Gordon Cordeiro, imprisoned for 30 years for a murder he claimed he didn't commit on Maui, was released after new DNA evidence overturned his conviction. His first impressions of the outside world revolved around its hyper-connectivity – “Everybody is looking at their phones,” he noted during a Zoom interview. He expressed gratitude for the advancements in DNA technology, visited his mother's grave (she died shortly after his arrest), and celebrated with family. While he finds readjusting to life challenging, particularly given the changes to Maui since his incarceration, the case highlights the power of technological advancements in achieving justice.

Masimo Sues US Customs to Block Apple's Restored Blood Oxygen Feature on Apple Watch

Following a patent infringement lawsuit by Masimo, Apple's blood oxygen feature on the Apple Watch was initially banned. While Apple disabled the feature via software, it recently re-enabled it, calling it a "redesigned" feature. Masimo now alleges that US Customs and Border Protection (CBP) overstepped its authority and violated due process by allowing Apple to restore the functionality. The lawsuit seeks to prevent CBP's decision and reinstate the original ban. The central issue is whether CBP violated due process and whether Apple's 'redesigned' feature still constitutes patent infringement.

Breaking Math.random(): An Improved Algorithm for Inverting Xorshift128+

The recent vulnerability CVE-2025-7783 exploits an edge case in the Node.js ecosystem, affecting applications using axios or the deprecated request library. The attack requires five consecutive outputs of JavaScript's Math.random(), allowing prediction of future outputs using the z3 solver. This blog post presents a more efficient approach. The author demonstrates a 226-operation algorithm to invert the Xorshift128+ algorithm used by Math.random(), requiring only two full 64-bit outputs. By analyzing Xorshift128+, knowing only the least significant 26 bits of R1 allows determining the remaining bits of L1 and R2. The post also discusses adapting this to the full Math.random() function, highlighting challenges due to bit truncation and proposing a solution using three outputs. Finally, the author shares their experience using ChatGPT for research, noting its potential while acknowledging current limitations.

Runtime Resizable Structs in Zig

This post proposes the concept of a "runtime resizable struct" in the Zig programming language. Existing methods for handling structs with runtime-determined field lengths are cumbersome, requiring manual size calculations, memory allocation, and alignment considerations. The author presents a solution leveraging Zig's compile-time metaprogramming capabilities. Using `ResizableArray` and `ResizableStruct`, a runtime-resizable struct is implemented, simplifying operations and avoiding potential errors. The core is compile-time offset and size calculations, providing `init`, `get`, `resize`, and `deinit` methods for memory management. A minimal implementation is available on GitHub, with community feedback encouraged.

Gondwanaland: An Ancient Supercontinent's Modern History

Around 400 million years ago, Australia was part of Gondwanaland, a supercontinent encompassing Antarctica, India, South America, and others. About 200 million years ago, it began breaking apart, leading to the continental configurations we see today. The Gondwana/Land project, an international research initiative, explores Gondwanaland's modern history, examining its impact from the remnants we protect to the resources we exploit. The name 'Gondwana' originates from a region in central India, and its modern usage is interwoven with colonial history, the Industrial Revolution, and resource extraction. Gondwanaland's mythical status, appearing in fiction and shaping cultural perceptions, is also investigated. While some Gondwanan remnants, like Australia's Gondwana Rainforests, are protected, their historical links to Indigenous peoples are often overlooked. This multidisciplinary project aims to unravel the complete story of Gondwanaland, revealing its significance in our modern world.
