Google clarified that “Not all affected email will necessarily be dangerous,” anyway it is important for a proper security posture to be extra careful about interacting with emails from unauthenticated sources.

Google is spending significant efforts against threat online like malware and phishing, and the IT giants also worked hard to protect its user’s privacy through the adoption of encryption.

In March, Google improved the Safe Browsing notification messages using a full-page warning related to state-sponsored hacking.

Starting this week, Gmail users will begin to see warnings if they click these links, further extending this protection to different web browsers and email apps. ” States the security advisory published by Google.

Back to the last security improvement announced by Google, the company plans to release it in a couple of weeks. The gradual rollout (potentially longer than 3 days for feature visibility) will impact all Gmail users.
