🔒 On September 29 at 12:00 PM ET, BleepingComputer and SC Media will host a live webinar featuring browser security experts from Push Security to examine how modern web browsers have become a primary enterprise attack surface. The session will cover malicious and shadow extensions, session token theft, OAuth abuse, and emerging ClickFix and FileFix techniques, plus mitigation strategies. Attendees will learn practical detection and response approaches to protect SaaS sessions, restore visibility at the web edge, and close gaps missed by traditional endpoint and identity controls.

🔒 Browser-targeted attacks are rising as adversaries treat the browser as the primary access point to cloud services and corporate data. The article defines browser-based attacks and enumerates six high-risk techniques: credential and session phishing, ClickFix-style copy-and-paste exploits, malicious OAuth consent flows, rogue extensions, malicious file delivery, and credential reuse where MFA gaps exist. These vectors are effective because modern work happens in decentralized SaaS environments and across many delivery channels, making traditional email- and network-centric defenses less reliable. The piece highlights visibility gaps for security teams and points to vendor platforms such as Push Security that claim to provide in-browser detection and remediation for AiTM phishing, OAuth abuse, and session hijacking.

🔒 An AI-integrated browser embeds large multimodal models into standard web browsers, allowing agents to view pages and perform actions—opening links, filling forms, downloading files—directly on a user’s device. This enables faster, context-aware automation and access to subscription or blocked content, but raises substantial privacy and security risks, including data exfiltration, prompt-injection and malware delivery. Users should demand features like per-site AI controls, choice of local models, explicit confirmation for sensitive actions, and OS-level file restrictions, though no browser currently implements all these protections.

🔒 Browser extensions present a significant, often unmonitored enterprise risk: they can run privileged code, inject scripts into web apps, access cookies and local storage, and persist via background processes. Keep Aware offers a Buyer’s Guide to Browser Extension Management that outlines these technical attack surfaces and illustrates how to reduce exposure. The guide compares common controls — GPO/MDM, EDR, enterprise browsers — with purpose-built browser security extensions to show trade-offs between visibility, enforcement, and user experience.

🔒 This article outlines six browser-based attack techniques—phishing with reverse-proxy AitM kits, ClickFix/FileFix command-injection lures, malicious OAuth grants, rogue extensions, weaponized file downloads, and credential attacks exploiting MFA gaps—that security teams must prioritize in 2025. It explains why the browser has become the primary attack surface as users access hundreds of cloud apps, and why traditional email/network controls and endpoint defenses often miss these threats. The piece argues that effective detection requires real-time browser-level visibility and management across managed and unmanaged apps, highlighting Push Security as a vendor offering such capabilities.

🔒 As enterprises shift more critical work to the browser, adversary Scattered Spider (UNC3944) targets live browser data—saved credentials, calendars, and session tokens—to achieve account takeover and persistent access. The article highlights techniques like Browser-in-the-Browser overlays, JavaScript injection, malicious extensions, and token theft that evade conventional EDR. It recommends elevating browser-native controls: runtime JavaScript protection, session-token binding, extension governance, API restrictions, and integrated browser telemetry so CISOs treat browser security as a primary defense layer.

🔒 Browser extensions can provide useful features but also expose users and organizations to significant risk. Malicious or compromised add-ons may steal credentials, session cookies, and browsing data, inject ads or malware, redirect users, or run background tasks like cryptomining. Scrutinize developer credentials and permissions, prefer official web stores, keep browsers updated, and enable security software and MFA.

🔒 Android's Advanced Protection extends Google's device-level security and integrates with Chrome on Android, enabling three core protections to guard high-risk users such as journalists and officials. It forces HTTPS via the Always Use Secure Connections mode, turns on full Site Isolation for devices with 4GB+ RAM, and reduces attack surface by disabling V8's higher-level JavaScript optimizers. Settings are available on Android 16 in Chrome 137+, and enterprises can control behaviors via policies while affected users should enable automatic updates and join the Advanced Protection Program for maximum defense. These measures trade some performance for stronger exploitation resistance.
