New Phishing Attack Creates Malicious Pages Inside the Victim’s Browser

Attackers are using trusted Microsoft services and blob URLs to generate stealthy phishing pages that leave defenders with no static website to detect or block. The post New Phishing Attack Creates Malicious Pages Inside the Victim’s Browser appeared first on SecurityWeek .

Report facts: The article describes a new phishing technique where attackers abuse trusted Microsoft services and blob URLs to dynamically generate malicious pages inside a victim’s browser, limiting defenders’ ability to rely on static domain or URL-based detection and blocking. This browser-local page generation makes the phishing content more stealthy and harder to classify using traditional web security controls. RealGround analysis: While the attack is not inherently AI-specific, organizations increasingly rely on AI-powered email, web, and security analytics that must handle such trusted-URL and dynamic-content evasion techniques. Hardening AI-driven detection pipelines and continuously red-teaming AI-based phishing and anomaly detection systems against these stealthy delivery methods is critical to avoid over-trusting content hosted under reputable cloud and productivity domains.
