Feed: All Latest | Websites Can Now Spy on You Through Your Hard Drive by Dan Goodin, Ars Technica AI generated summary, Read the full article for complete information. Websites can now covertly track visitors by measuring subtle SSD activity through a newly disclosed technique called FROST (fingerprinting remotely using OPFS‑based SSD timing). By running JavaScript in the browser that repeatedly reads from a large file stored in the origin‑private file system (OPFS), attackers can detect latency variations caused by competing I/O operations and, using a pretrained convolutional neural network, infer which other sites and native applications a user has open—even across different browsers. Unlike earlier side‑channel attacks, FROST works entirely within the browser and requires no user interaction beyond visiting the malicious page, though it needs a very large OPFS file (≈ 1 GB) on the same SSD, which limits its stealth at scale. Mitigations include closing unused tabs promptly, monitoring and restricting OPFS file sizes, and browser vendors could further limit file allocation. So far there is no evidence of FROST being used in the wild, and the researchers demonstrated the attack on an M2 Mac, with comparable results expected on Linux.

The Salsus people began life in the deserts of Exoplanet 74657. They, like all other life, used available resources to build homes. For them it was salt. They mastered the art of manufacturing perfect rectangular blocks. Eventually, one king built the customary-next-step-in-cultural-evolution pyramid. But now, centuries later, the climate has shifted. It rains one day every ten years on the desert, which is slowly, ever so slowly, dissolving the pyramid (but creating beautiful crystals on the outer surface). Now that politics in the region has stabilized, the decades old plans to build a protective roof over the pyramid (and the controversial ‘Shopping Destination and Leisure Complex’) are being dusted off. #scifi #exoplanet #MicroFiction #nature #photography #frost #ice

Once a year, maybe, weather conditions are just right to produce hoar frost and rime. When the sun comes out, the world turns magical for a few brief hours. #winter #frost #yyc #outdoorphotography #PhotoMonday #ice
