Crooks behind a newly identified malware campaign are targeting Windows 10 with malware that can infect systems via a technique that cleverly bypasses Windows cybersecurity protections called User Account Control. Iwamaye wrote in a blog post published Thursday, the attack chain is initiated when a Chrome browser user visits a malicious website and a "Browser ad service" prompts the user to take an action.

Google has released Chrome 95.0.4638.69 for Windows, Mac, and Linux to fix two zero-day vulnerabilities that attackers have actively exploited."Google is aware that exploits for CVE-2021-38000 and CVE-2021-38003 exist in the wild," Google disclosed in the list of security fixes in today's Google Chrome release.

Google on Thursday pushed urgent security fixes for its Chrome browser, including a pair of new security weaknesses that the company said are being exploited in the wild, making them the fourth and fifth actively zero-days plugged this month alone. As is usually the case, the tech giant has refrained from sharing any additional details regarding how these zero-day vulnerabilities were used in attacks until a majority of users are updated with the patches, but noted that it's aware that "Exploits for CVE-2021-37975 and CVE-2021-37976 exist in the wild."

Google has released Chrome 94.0.4606.61 for Windows, Mac, and Linux, an emergency update addressing a high-severity zero-day vulnerability exploited in the wild. The update was available immediately when BleepingComputer manually checked for new updates from Chrome menu > Help > About Google Chrome.

Google on Monday released security updates for Chrome web browser to address a total of 11 security issues, two of which it says are actively exploited zero-days in the wild. Tracked as CVE-2021-30632 and CVE-2021-30633, the vulnerabilities concern an out of bounds write in V8 JavaScript engine and a use after free flaw in Indexed DB API respectively, with the internet giant credited anonymous researchers for reporting the bugs on September 8.

Google has addressed two zero-day security bugs that are being actively exploited in the wild. Google is restricting any technical details "Until a majority of users are updated with a fix," it said.

A newly discovered side-channel attack demonstrated on modern processors can be weaponized to successfully overcome Site Isolation protections weaved into Google Chrome and Chromium browsers and leak sensitive data in a Spectre-style speculative execution attack. Dubbed "Spook.js" by academics from the University of Michigan, University of Adelaide, Georgia Institute of Technology, and Tel Aviv University, the technique is a JavaScript-based line of attack that specifically aims to get around barriers Google put in place after Spectre, and Meltdown vulnerabilities came to light in January 2018, thereby potentially preventing leakage by ensuring that content from different domains is not shared in the same address space.

Google Chrome will no longer show whether a site you are visiting is secure and only show when you visit an insecure website. Currently, when you visit a secure site, Google Chrome will display a little locked icon indicating that your communication with the site is encrypted, as shown below.

A malware known for targeting macOS operating system has been updated once again to add more features to its toolset that allows it to amass and exfiltrate sensitive data stored in a variety of apps, including apps such as Google Chrome and Telegram, as part of further "Refinements in its tactics." Earlier this April, XCSSET received an upgrade that enabled the malware authors to target macOS 11 Big Sur as well as Macs running on M1 chipset by circumventing new security policies instituted by Apple in the latest operating system.

Security researchers have published details about the method used by a strain of macOS malware to steal login information from multiple apps, enabling its operators to steal accounts. Dubbed XCSSET, the malware keeps evolving and has been targeting macOS developers for more than a year by infecting local Xcode projects.
