A latest cybersecurity warning highlights important dangers related to AI-powered browser brokers, particularly for customers of Chrome and Microsoft Edge. Based on cybersecurity agency SquareX, the widespread adoption of agentic AI—AI instruments able to autonomously performing duties—might pose an escalating risk to enterprise safety.
Browser AI brokers are actually utilized by roughly 79% of organizations, primarily to spice up productiveness by automating duties. Nevertheless, not like human customers, these brokers lack the flexibility to acknowledge malicious web sites, suspicious URLs, extreme permission requests, or some other pink flags that might usually alert an worker to a phishing try or different risk. In consequence, attackers are actually focusing on these brokers with browser-based assaults that conventional safety measures might not forestall.
SquareX’s Vivek Ramachandran emphasizes that present browser protections, equivalent to website whitelisting, blacklisting, and browser hardening options in enterprise variations of Chrome and Edge, are inadequate. Assaults can exploit professional browser features, like OAuth authentication flows, making it almost inconceivable to dam them via typical means like proxy filtering or browser settings alone.

A very alarming vulnerability arises from the truth that browser AI brokers function with the identical privileges and authentication credentials as human customers. In a single proof-of-concept assault, a browser agent was tricked into granting entry to a malicious app, regardless of clear warning indicators. As a result of browsers can’t distinguish between consumer actions and AI-driven workflows, the potential for unauthorized entry to delicate data—emails, passwords, bank card particulars, and enterprise purposes—is dangerously excessive.
Google recommends enabling Chrome’s “Enhanced Safety” mode, which gives warnings about doubtlessly dangerous web sites and downloads, together with rising threats not beforehand recognized. Whereas this presents some protection, SquareX argues it isn’t sufficient. The agency requires browser-native safety controls, just like Endpoint Detection and Response (EDR) programs, to govern AI agent conduct.
Ramachandran notes a rising must rethink browser safety as these AI instruments grow to be extra succesful and embedded in every day workflows. Based on Gartner, by 2028, no less than 15% of routine on-line duties shall be carried out by browser AI brokers.
SquareX warns that with out ample safeguards, these instruments might shortly grow to be a main vulnerability in enterprise environments, as attackers are already designing malicious websites particularly to take advantage of their weaknesses.
