Meta Platforms' WhatsApp and Cloudflare have banded together for a new initiative called Code Verify to validate the authenticity of the messaging service's web app on desktop computers. Available in the form of a Chrome and Edge browser extension, the open-source add-on is designed to "Automatically verif[y] the authenticity of the WhatsApp Web code being served to your browser," Facebook said in a statement.

Mozilla has pushed out-of-band software updates to its Firefox web browser to contain two high-impact security vulnerabilities, both of which it says are being actively exploited in the wild. Tracked as CVE-2022-26485 and CVE-2022-26486, the zero-day flaws have been described as use-after-free issues impacting the Extensible Stylesheet Language Transformations parameter processing and the WebGPU inter-process communication Framework.

The particular provision requires web browsers like Chrome, Safari, and Firefox to accept QWACs, which practically compels browser developers and security advocates to ease their security stance. TLS certificates are vital for the online exchange of sensitive information with websites such as passwords, sensitive uploads, or payment details.

Google on Monday rolled out fixes for eight security issues in the Chrome web browser, including a high-severity vulnerability that's being actively exploited in real-world attacks, marking the first zero-day patched by the internet giant in 2022. The shortcoming, tracked CVE-2022-0609, is described as a use-after-free vulnerability in the Animation component that, if successfully exploited, could lead to corruption of valid data and the execution of arbitrary code on affected systems.

In the past few days, both Apple and Adobe have published software updates to close off zero-day security holes that were already being exploited by attackers. In other words, now matter how quickly you update against a zero-day once the patch is announced, you know that someone - and you have to hope that it wasn't you! - has already been attacked and pwned, even if they're accustomed to patching promptly themselves.

A financially-motivated malware campaign has compromised over 800 WordPress websites to deliver a banking trojan dubbed Chaes targeting Brazilian customers of Banco do Brasil, Loja Integrada, Mercado Bitcoin, Mercado Livre, and Mercado Pago. "Chaes is characterized by the multiple-stage delivery that utilizes scripting frameworks such as JScript, Python, and NodeJS, binaries written in Delphi, and malicious Google Chrome extensions," Avast researchers Anh Ho and Igor Morgenstern said.

Trojan titan TrickBot has added a striking anti-debugging feature that detects security analysis and crashes researcher browsers before its malicious code can be analyzed. The new anti-debugging feature was discovered by Security Intelligence analysts with IBM, who reported the emergence of a variety of TrickBot tactics aimed at making the job of security researcher more difficult, including server-side injection delivery and secure communications with the command-and-control server to keep code protected.

The notorious TrickBot malware has received new features that make it more challenging to research, analyze, and detect in the latest variants, including crashing browser tabs when it detects beautified scripts. TrickBot has dominated the malware threat landscape since 2016, constantly adding optimizations and improvements while facilitating the deployment of damaging malware and ransomware strains.

A software bug introduced in Apple Safari 15's implementation of the IndexedDB API could be abused by a malicious website to track users' online activity in the web browser and worse, even reveal their identity. That's not the case with how Safari handles the IndexedDB API in Safari across iOS, iPadOS, and macOS. "In Safari 15 on macOS, and in all browsers on iOS and iPadOS 15, the IndexedDB API is violating the same-origin policy," Martin Bajanik said in a write-up.

Folks at Technische Universität Wien in Austria have devised a formal security framework called WebSpec to analyze browser security. They've used it to identify multiple logical flaws affecting web browsers, revealing a new cookie-based attack and an unresolved Content Security Policy contradiction.
