Google Chat has replaced Hangouts and now displays banners warning you about possible phishing and malware attacks from personal accounts, Google announced Thursday† This change for Google Chat is the latest extension of Google’s efforts to prevent phishing.
At the 2022 I/O Developer Conference, Google discussed several security measures it has implemented to improve user security, including warnings about potential vulnerabilities and recommendations for fixing them. Google has also laid out other plans for security measures, such as enhanced two-step verification, ad customization, and increased data security.

Google’s new warning banners first appeared in Gmail on Workspace accounts to indicate attempts to lure someone with a link that could be used for malware, phishing or ransomware. In late April, Google expanded the banners to Google Docs, warning users about suspected malicious files in various Google Workspace apps (Documents, Sheets, Slides, and Drawing), regardless of where they opened the link.
This new feature will be rolled out in the coming weeks and will be available to both personal Google accounts and all Google Workspace customers.
