First couple of paragraphs in Dark Reading story says it all:
Both the Google Chrome and Mozilla Firefox browsers currently are under separate attacks, the former from actors exploiting a zero-day bug and the latter from a list of malicious extensions that are actively compromising users.
Google rushed out a stable channel update on Monday to patch the fourth zero-day flaw found in its browser this year, a high-severity type confusion flaw tracked as CVE-2025-6554, according to a Google security advisory. The flaw, which allows attackers to execute arbitrary code, is under active exploitation and should be patched immediately.
Why is this important? Because when(not if) you get a phishing attempt and they try to download and install on your computer, they are trying to insert malware and if your browser is the weak point it is almost easy for them.
So it is important to keep updating your browser as soon as practical. Contact to discuss or to create your own security program with my security policy templates in the store/shop.
