AI-Powered Threats Target Browsers
On June 30, 2025, Forbes published a critical warning for users of Google Chrome and Microsoft Edge, highlighting a new wave of AI-driven cyberattacks exploiting browser vulnerabilities, particularly through agentic AI tools. Authored by Zak Doffman, the report urges users to enable the highest browser protection settings to mitigate risks, as AI tools exhibit limited cyber awareness, likened to a “toddler” navigating a work PC. This article details the threat, recommended actions, and broader context, drawing from the Forbes report and related sources.
The Threat: AI-Driven Attacks and Browser Vulnerabilities
-
AI Security Risks: The rise of agentic AI, capable of autonomous actions, introduces a “security nightmare” due to its potential to interact with malicious content without robust safeguards. Forbes notes that AI tools lack the cyber awareness to avoid phishing sites, malicious downloads, or exploitative extensions, amplifying risks on browsers like Chrome and Edge.
-
Browser-Specific Issues: Chrome, with its 65% market share, is the primary target, but Edge, built on the same Chromium platform, is equally vulnerable. Recent vulnerabilities, like CVE-2025-6554 (a type confusion flaw in Chrome’s V8 JavaScript engine), have been actively exploited via crafted HTML pages, risking remote code execution.
-
Exploitation Methods: Attackers use phishing emails, fake document websites (e.g., mimicking Adobe or DocuSign), and malicious browser extensions to steal credentials, crypto wallets, or install malware. A 137% surge in tech support scams from November 2024 to April 2025 underscores the growing threat.
Recommended Actions: Update and Secure Your Browser
-
Enable Enhanced Protection:
-
Chrome: Go to Settings > Privacy and Security > Safe Browsing and select “Enhanced Protection.” This offers warnings for dangerous sites, downloads, and extensions, including previously unknown threats. Google’s Safe Browsing protects against phishing and malware, critical when using AI tools.
-
Edge: Navigate to Settings > Privacy, Search, and Services > Security and enable “Enhanced Security.” This leverages Microsoft Defender SmartScreen to block malicious sites and downloads.
-
-
Update Immediately: Ensure Chrome is updated to version 138.0.7204.96/.97 (Windows/Mac) to patch CVE-2025-6554, mitigated on June 24, 2025, and fixed on July 1. Edge users should also update for the same fix. Restart browsers post-update to apply changes, as Incognito tabs won’t reopen.
-
Avoid Risky Extensions: Limit browser extensions, as 95% of Chrome extensions have fewer than 10,000 installs and are prone to hijacking. Check Settings > Extensions and remove unverified or unused ones.
-
Beware Document Scams: Avoid free online document converters or sharing sites (e.g., fake Adobe or DocuSign links), which may embed malicious JavaScript or Visual Basic code. Report suspicious sites to IC3.gov.
Context: Ongoing Browser Security Challenges
-
Recent Exploits: In 2025, Chrome and Edge faced multiple zero-day vulnerabilities:
-
CVE-2025-5419 (May 2025): An out-of-bounds read/write in V8, exploited via crafted HTML pages, prompted emergency updates for Chromium-based browsers.
-
CVE-2025-2783 (March 2025): A sandbox escape in Chrome’s Mojo component was used to deploy the Trinper backdoor via phishing emails.
-
CVE-2025-4664 (May 2025): A query parameter takeover risked account hijacking, fixed with a U.S. government mandate to update by June 5.
-
-
Microsoft vs. Google: Microsoft pushes Edge as a safer alternative, citing SmartScreen and warnings against Chrome-targeted malware like StilachiRAT, which steals crypto wallet data. However, both browsers share Chromium vulnerabilities.
-
AI’s Role: The surge in AI-fueled phishing, with 90% of email traffic being spam or malicious, heightens risks. Google’s push for passkeys over passwords aims to counter this, but only 46–48% of users enable two-factor authentication (2FA), leaving many vulnerable.
Community and Industry Reactions
Social Media Sentiment
X posts underscore urgency, with @TheHackersNews and @H4ckmanac warning of CVE-2025-6554’s active exploitation, urging immediate updates. @the_yellow_fall highlighted the V8 flaw’s remote code execution risk, while @Huntio referenced earlier Chrome exploits like CVE-2025-2783. Users like @KamilZm emphasized the need to avoid malicious web pages.
Industry Insights
Analysts stress proactive measures. Forbes warns that AI tools’ naivety amplifies browser risks, with LayerX noting extensions’ “extensive access permissions” as a trojan horse for enterprises. Bleeping Computer highlighted a 2024 surge in extension hijacking, while HelpNet and Google’s Threat Analysis Group confirmed CVE-2025-6554’s severity, mitigated swiftly on June 24.
The Bigger Picture: Cybersecurity in 2025
The convergence of AI-driven attacks and browser vulnerabilities marks 2025 as a critical year for cybersecurity. India’s internet user base, over 900 million, faces similar risks, with phishing and malware campaigns targeting its 20% annual digital growth. Enterprises must prioritize browser security, as 95% of Chrome extensions remain low-visibility and high-risk. Users worldwide, including in India, should adopt enhanced protection and vigilant browsing habits to counter evolving threats.
Act Now to Protect Your Browser
The June 30, 2025, Forbes warning highlights a “massive security risk” for Chrome and Edge users, driven by AI-powered attacks exploiting vulnerabilities like CVE-2025-6554. With Chrome’s 65% market dominance and shared Chromium risks with Edge, users must enable enhanced protection, update browsers immediately, and avoid risky extensions and document sites. India’s growing digital population, alongside global users, faces heightened phishing and malware threats. By adjusting settings and staying vigilant, users can safeguard their data in an increasingly hostile cyber landscape.
