Websites have a new way to spy on visitors: analyzing their SSD activity

While each file system is sandboxed, meaning it’s isolated from other websites and from the device system itself, the JavaScript can measure the I/O interactions. Then, by running those interactions through a pretrained convolutional neural network—a system that uses deep learning to analyze text, audio, and images—the attacker can deduce various apps and websites open… Read More »

Millions of AI agents imperiled by critical vulnerability in open source package

Millions of AI agents and tools around the world have been imperiled by a critical vulnerability that can allow hackers to breach the servers running them and make off with sensitive data and credentials to third-party accounts, a security researcher is warning. The vulnerability is present in Starlette, an open source framework that its developer… Read More »

Texas AG sues Meta over claims that WhatsApp doesn’t provide end-to-end encryption

The Texas Attorney General has sued Meta over allegations that the company’s WhatsApp messenger, used by more than 3 billion people, doesn’t provide the end-to-end encryption (E2EE) it has long claimed. Since at least 2016, Meta (then named Facebook) has said WhatsApp provides robust end-to-end encryption, meaning that messages are encrypted on a sender’s device… Read More »

A hacker group is poisoning open source code at an unprecedented scale

A so-called software supply chain attack, in which hackers corrupt a legitimate piece of software to hide their own malicious code, was once a relatively rare event but one that haunted the cybersecurity world with its insidious threat of turning any innocent application into a dangerous foothold in a victim’s network. Now one group of… Read More »

Google publishes exploit code threatening millions of Chromium users

Google on Wednesday published exploit code for an unfixed vulnerability in its Chromium browser codebase that threatens millions of people using Chrome, Microsoft Edge, and virtually all other Chromium-based browsers. The proof-of-concept code exploits the Browser Fetch programming interface, a standard that allows long videos and other large files to be downloaded in the background.… Read More »

In stunning display of stupid, secret CISA credentials found in public GitHub repo

Security researcher Brian Krebs brings us the news that America’s Cybersecurity & Infrastructure Agency (CISA) has had a large store of plaintext passwords, SSH private keys, tokens, and “other sensitive CISA assets” exposed in a public GitHub repo since at least November 2025. The now-offline public repo—named, somewhat aspirationally, “Private-CISA”—was brought to Krebs’ attention by… Read More »

Zero-day exploit completely defeats default Windows 11 BitLocker protections

A zero-day exploit circulating online allows people with physical access to a Windows 11 system to bypass default BitLocker protections and gain complete access to an encrypted drive within seconds. The exploit, named YellowKey, was published earlier this week by a researcher who goes by the alias Nightmare-Eclipse. It reliably bypasses default Windows 11 deployments… Read More »

Linux bitten by second severe vulnerability in as many weeks

Both privilege escalation vulnerabilities stem from bugs in the kernel’s handling of page caches stored in memory, allowing untrusted users to modify them. They target caches in networking and memory-fragment handling components. Specifically, CVE-2026-43284 attacks the esp4 and esp6 () processes, and CVE-2026-43500 zeroes in on rxrpc. Last week’s CopyFail exploited faulty page caching in… Read More »

Chaos erupts as cyberattack disrupts learning platform Canvas amid finals

Chaos erupted at schools and colleges throughout the US on Thursday as a cyberattack disrupted online learning platform Canvas just as students were due to take final exams. Canvas parent company Instructure said that as of Friday morning, the platform was back online. Instructure said it temporarily took Canvas offline on Thursday after identifying unauthorized… Read More »
