WebGPU Widens Mobile Attack Surface

Browser GPU APIs (like WebGPU) introduce new, high‑performance pathways that attackers can chain with browser and OS flaws to break sandboxes on phones and steal sensitive data in minutes. The DarkSword exploit shows those paths can be exploited on older iOS builds via Safari, targeting messages, credentials and crypto wallets with little forensic trace. — If GPU‑backed browser APIs become a common attack vector, device makers, browser vendors and regulators must rethink update urgency, platform hardening, and disclosure/patching practices for mobile security.
