EDR is still essential for detecting host execution, but it can miss attacks that stay inside browser-based SaaS sessions, identity workflows, and cloud applications. The article explains how browser controls, identity protections, and SaaS-specific policies can stop threats like AiTM phishing, malicious extensions, and ClickFix attacks before they reach endpoint telemetry. #UNC6395 #SalesloftDrift #Storm2755 #Microsoft365 #Workday #TerminalFix #NordLayerBrowser
Keypoints
- EDR cannot see every malicious action that occurs only in the browser.
- OAuth abuse and SaaS access can enable data theft without malware execution.
- AiTM phishing can steal credentials, cookies, and session tokens in real time.
- Malicious browser extensions can read web content and exfiltrate data unnoticed.
- Browser controls should block phishing, restrict extensions, and limit risky actions.
