What the 2026 DBIR Confirms: Attacks Are Living in the Browser

The 2026 Verizon Data Breach Investigations Report (DBIR) warns that the web browser is now the primary enterprise attack surface: attackers increasingly use AiTM phishing, browser-in-the-browser, malicious extensions, infostealers, and unauthorized AI integrations to steal credentials, session cookies, and sensitive data. The report emphasizes that traditional endpoint, network, and email-centric controls have a significant blind spot for these browser-layer attacks and recommends browser-layer security platforms, zero-trust session controls, phishing-resistant MFA, and targeted user education.
