Chrome 136 Finally Kills 23-Year-Old Browser History Sniffing Vulnerability

A 23-year-old vulnerability allowing websites to sniff users' browsing history through CSS :visited pseudo-class is finally being eradicated in Chrome 136. Previous attempts to mitigate the issue, which involved checking link colors to determine if a page had been visited, proved insufficient. Chrome 136 introduces a novel 'partitioning' mechanism, linking visited history to the link URL, top-level domain, and frame origin, preventing cross-site access to browsing history. This breakthrough represents a significant leap forward in browser privacy and concludes a decades-long arms race between attackers and defenders.

Modeling Open and Closed Universes of Choices in Rust

2025-02-21

Modeling Open and Closed Universes of Choices in Rust

This article explores how to model choices in Rust, distinguishing between closed universes (where all options are known and fixed, like Rust's `Option` type) and open universes (where new options can be added). For closed universes, enums are suitable. Semi-open universes (where library authors can add options but users can't), are best handled with non-exhaustive enums, forcing users to account for wildcard patterns and ensuring API backward compatibility. Fully open universes are best addressed with strings or newtypes, or traits for more flexibility. The article also discusses the pitfalls of using an 'Unknown' variant and explores the use of sealed traits. The author concludes by recommending a case-by-case approach, weighing the trade-offs between the simpler string-based approach and the more powerful, yet more complex, trait-based approach.

C to FlipJump: A Minimalist RISC-V Virtual Machine

The c2fj project is a compiler that translates C code into FlipJump, a minimalist instruction set virtual machine. It first compiles C code into a RISC-V ELF file, then translates RISC-V instructions into FlipJump instructions, and finally runs the resulting FlipJump program. This process cleverly leverages FlipJump's space optimization, allowing for efficient compilation even of large C codebases. c2fj supports various compilation flags and provides Makefile support for complex projects. It also includes a minimal C library implementing necessary system calls such as `exit`, `getc`, `putc`, and `sbrk`.

Government-Backed Hackers Behind Most Zero-Day Exploits in 2024

Government-Backed Hackers Behind Most Zero-Day Exploits in 2024

Google's latest research reveals that government-backed hackers were responsible for the majority of attributed zero-day exploits in 2024. While the total number of zero-days decreased from 98 in 2023 to 75 in 2024, Google attributed at least 23 to government actors. Ten were directly linked to government hackers (five to China, five to North Korea), and eight originated from spyware makers like NSO Group, which primarily sell to governments. The remaining attributed zero-days were likely exploited by cybercriminals. Although spyware companies' zero-day production is slowing, Google notes that the industry will continue to thrive as long as government demand persists. Importantly, security features like iOS/macOS Lockdown Mode and Google Pixel's MTE are proving effective against these attacks, highlighting advancements in zero-day defense.

Poka-Yoke: The Japanese Art of Mistake-Proofing

2025-01-09

Poka-yoke, meaning "mistake-proofing" in Japanese, is a lean manufacturing concept originating from the Toyota Production System. It involves designing mechanisms to prevent, correct, or highlight human errors in a process, thereby eliminating defects. A simple example is a car's clutch pedal—it's a poka-yoke, forcing the driver to depress it before starting the engine. This approach not only improves product quality but also reduces training costs, lessens quality control burdens, and ultimately achieves 100% built-in quality control.

Colossal's 'Dire Wolves': Gene Editing Sparks Controversy

Colossal Biosciences claims to have resurrected the extinct dire wolf, using gene editing to create grey wolf pups—Remus, Romulus, and Khaleesi—with some dire wolf traits. However, studies show grey wolves and dire wolves diverged 6 million years ago, with significant genetic differences. Colossal's claim of achieving this with only 20 gene edits is controversial. The three gene-edited pups are under observation in a reserve, and breeding is prohibited. This raises questions about species definition and the ethical challenges of gene editing.

Fedora's 32-bit Sunset Threatens Popular Handheld Gaming Distro Bazzite

Fedora's 32-bit Sunset Threatens Popular Handheld Gaming Distro Bazzite

Fedora Linux's proposal to drop 32-bit support has sparked controversy, particularly threatening the popular handheld gaming distribution Bazzite. Bazzite's creator, Kyle Gospodnetich, strongly opposes the change, arguing it would kill projects like Bazzite and damage Fedora's public image. He points out that even with built Steam packages, basic use cases would break, and Flatpak wouldn't solve issues with Bazzite's reliance on 32-bit architecture for Steam Big Picture Mode. Currently, the proposal is unlikely to pass for Fedora 44, but ideally, Valve would port the Steam client to 64-bit, resolving many problems. The issue also impacts OBS Studio game capturing and FEX.
