Google beefs up Gmail security to fight phishing attempts (Engadget)

See this Google post for more details

"First, Google has implemented a machine learning model to keep spam out of your inbox and to better detect phishing messages. The company estimates that between 50 and 70 percent of Gmail messages are spam and the new system blocks them with 99.9 percent accuracy. The machine learning system works with Google Safe Browsing to selectively delay emails (less than 0.05 percent of them) for added phishing analyses. It then generates URL click-time warnings for suspicious links.

Additionally, G Suite users trying to reply to someone outside of their company will get a warning asking if they really want to send the message. But users' existing and regular contacts will be picked up by Gmail so you're not bugged with excessive warnings.

Finally, Google also announced improved detection of malicious attachments in order to keep out sneaky ransomware and malware pushes, saying, maybe a little dramatically, "While the bad guys never rest, neither do we.""
