A latest cybersecurity warning highlights vital dangers related to AI-powered browser brokers, particularly for customers of Chrome and Microsoft Edge. In accordance with cybersecurity agency SquareX, the widespread adoption of agentic AI—AI instruments able to autonomously performing duties—could pose an escalating menace to enterprise safety.
Browser AI brokers are actually utilized by roughly 79% of organizations, primarily to spice up productiveness by automating duties. Nevertheless, in contrast to human customers, these brokers lack the power to acknowledge malicious web sites, suspicious URLs, extreme permission requests, or some other crimson flags that may usually alert an worker to a phishing try or different menace. Because of this, attackers are actually concentrating on these brokers with browser-based assaults that conventional safety measures could not stop.
SquareX’s Vivek Ramachandran emphasizes that present browser protections, resembling web site whitelisting, blacklisting, and browser hardening options in enterprise variations of Chrome and Edge, are inadequate. Assaults can exploit authentic browser capabilities, like OAuth authentication flows, making it practically not possible to dam them by standard 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 functions—is dangerously excessive.
Google recommends enabling Chrome’s “Enhanced Safety” mode, which offers warnings about doubtlessly dangerous web sites and downloads, together with rising threats not beforehand recognized. Whereas this affords some protection, SquareX argues it isn’t sufficient. The agency requires browser-native safety controls, much like Endpoint Detection and Response (EDR) techniques, to govern AI agent habits.
Ramachandran notes a rising have to rethink browser safety as these AI instruments turn out to be extra succesful and embedded in each day workflows. In accordance with Gartner, by 2028, not less than 15% of routine on-line duties might be carried out by browser AI brokers.
SquareX warns that with out ample safeguards, these instruments may rapidly turn out to be a main vulnerability in enterprise environments, as attackers are already designing malicious websites particularly to take advantage of their weaknesses.
