Google Chrome Hit In Another Mysterious Zero-Day Attack

wiredmikey shares a report from SecurityWeek: Google late Tuesday shipped another urgent security patch for its dominant Chrome browser and warned that attackers are exploiting one of the zero-days in active attacks. This is the fourth in-the-wild Chrome zero-day discovered so far in 2021 and the continued absence of IOC data or any meaningful information about the attacks continue to raise eyebrows among security experts.

The newest Chrome update -- 90.0.4430.85 -- is available for Windows, Mac and Linux users and is being rolled out via the browser's automatic update mechanism. The vulnerability being exploited is identified as CVE-2021-21224 and simply described as a 'type confusion' in the V8 Chrome rendering engine.

'Google is aware of reports that exploits for CVE-2021-21224 exist in the wild,' the company said, with no additional details.
