CVE-2026-2828-WebGPU-Cross-Origin-Pixel-Stealing-via-Timing

4. CVE-2026-2828 – WebGPU Cross‑Origin Pixel Stealing via Timing Overview A malicious website uses WebGPU compute shader timing to measure rendering time of a cross‑origin iframe, recovering pixel values of sensitive content e.g., banking details. Severity: High Information Disclosure...

Pixel-stealing “Pixnapping” attack targets Android devices

Researchers at US universities have demonstrated how a malicious Android app can trick the system into leaking pixel data. That may sound harmless, but imagine if a malicious app on your Android device could glimpse tiny bits of information on your screen—even the parts you thought were secure,...

New Pixnapping Android Flaw Lets Rogue Apps Steal 2FA Codes Without Permissions

Android devices from Google and Samsung have been found vulnerable to a side-channel attack that could be exploited to covertly steal two-factor authentication 2FA codes, Google Maps timelines, and other sensitive data without the users' knowledge pixel-by-pixel. The attack has been codenamed...

Pixnapping: Bringing Pixel Stealing out of the Stone Age

Pixel stealing attacks enable malicious websites to leak sensitive content displayed in victim websites. The idea, introduced by Stone in 2013, is to embed victim websites in iframes and use SVG filters to compute on, and create side channels as a function of, those websites' pixels. Fortunately,...

For example, attackers can sometimes accurately...

EXAM: Exploiting Exclusive System-Level Cache in Apple M-Series SoCs for Enhanced Cache Occupancy Attacks

Cache occupancy attacks exploit the shared nature of cache hierarchies to infer a victim's activities by monitoring overall cache usage, unlike access-driven cache attacks that focus on specific cache lines or sets. There exists some prior work that target the last-level cache LLC of Intel...
