The article explains how third‑party cookies enable cross‑site tracking, why browsers are deprecating them, introduces the SameParty attribute as a partial mitigation, and details Chrome's CHIPS proposal with partitioned cookies that isolate cookie storage per top‑level site to protect user privacy.
This article explains the Spectre hardware side‑channel vulnerability, its exploitation via speculative execution and cache timing, demonstrates simple JavaScript attacks, and reviews various browser mitigation strategies such as cache‑control headers, disabling high‑resolution timers, COOP, COEP, and CORB to reduce attack surface.
This article explains the Spectre hardware vulnerability, how it leverages speculative execution and side‑channel attacks to read arbitrary memory, and reviews the browser‑level defenses such as cache policies, timer reduction, rel="noopener", COOP, COEP and CORB that aim to mitigate its impact.
Chrome 93, released on August 31, 2021, introduces 18 new features including the Error Cause proposal, Object.hasOwn method, port blocking to mitigate ALPACA attacks, removal of 3DES cipher suites, cross‑device WebOTP support, and SVG support in the Clipboard API, all enhancing web development and security.
A tech roundup reveals a former actor turned PhD, exposes a massive Amazon paid‑review fraud, extends Linux 5.10 LTS support to 2026, details Edge’s false Firefox block, showcases Google’s new Chrome media controls, and announces China’s 62‑qubit programmable quantum prototype.
This article explains the purpose, possible values, and security impact of the Sec-Fetch request headers introduced by the Fetch Metadata specification, showing how browsers automatically add them, how servers can use them to filter illegal requests, and providing practical policy examples and code snippets.
This article explores how HTTPS certificates are validated, why revocation mechanisms like CRL and OCSP often fall short, compares browser implementations, and discusses practical mitigation techniques such as OCSP stapling and Must‑Staple to improve TLS security.
Microsoft released a Chrome extension called Windows Defender Browser Protection that ports Edge’s SmartScreen anti‑phishing technology to Chrome, showing red warning pages for malicious links and reportedly achieving a 99% phishing detection rate compared with Chrome’s 87% in NSS Labs tests.
