Executive Intelligence Summary

In late 2025 and early 2026, a massive “Prompt Poaching” campaign has unmasked the terminal risk of unhardened browser extensions. OX Security researchers discovered that over 900,000 Chrome users have had their ChatGPT and DeepSeek conversations siphoned by malicious extensions impersonating the legitimate AITOPIA sidebar. These extensions, which were even granted Google’s “Featured” badge, exfiltrate full prompts, responses, and URLs every 30 minutes. CyberDudeBivash Pvt. Ltd. has unmasked the DOM-Scraping primitives, the role of SecretsGuard™ in remediating siphoned session tokens, and why your browser is currently a forensic open book for industrial data harvesters.

1. Anatomy of the Siphon: Unmasking the Malicious Clones

The threat landscape has been unmasked by two primary malicious actors on the Chrome Web Store: “Chat GPT for Chrome with GPT-5, Claude Sonnet & DeepSeek AI” (600,000+ users) and “AI Sidebar with Deepseek, ChatGPT, Claude and more” (300,000+ users). These extensions leverage broad “read all website content” permissions to monitor your interaction with AI models.

The technical primitive exploited is DOM-Based Conversation Scraping. When the extension detects a URL containing “chatgpt” or “deepseek,” it scans the web page for specific Document Object Model (DOM) elements that hold the chat history. It then extracts the raw text of your queries and the AI’s responses, storing them in a local system database before exfiltrating them in batches to remote C2 servers like https://www.google.com/search?q=chatsaigpt.com and https://www.google.com/search?q=deepaichats.com.

This data—including proprietary source code, business strategies, and PII—is weaponized for corporate espionage or sold on underground forums. At CyberDudeBivash Pvt. Ltd., we call this the Neural Shadow Siphon.

2. Logic Liquidation: Impersonation and Persistence Tactics

The Forensic Differentiator for this 2026 campaign is its use of “Social Trust Siphoning.” The attackers copied the interface and functionality of a legitimate tool from AITOPIA, even managing to secure a “Featured” badge that tricked nearly a million users into believing the software was vetted.

The campaign also unmasked a technical primitive for Persistence: when a user uninstalls one of the malicious extensions, it automatically opens a new browser tab prompting the installation of the other malicious variant. This creates a Loop-Based Siphon, ensuring that at least one malicious agent stays active in the browser. Furthermore, the threat actors used the AI-powered tool Lovable to generate legitimate-looking privacy policies and redirection sites to hide their tracks.

To defend against this, you must anchor your browser identity in Silicon. CyberDudeBivash Pvt. Ltd. mandates Physical FIDO2 Hardware Keys from AliExpress for every cloud administrative and exchange session. Furthermore, SecretsGuard™ is non-negotiable. Siphoning agents target extension metadata to find siphoned OpenAI API Keys and session tokens stored in local browser storage. SecretsGuard™ unmasks these siphoned tokens and remediates them across your global fleet, replacing them with PQC-hardened primitives.

LIQUIDATE THE SHADOW SIPHON: SECRETSGUARD™

Extension-based breaches start with siphoned Browser Secrets and Chat Logs. SecretsGuard™ by CyberDudeBivash Pvt. Ltd. is the only Automated Forensic Scanner that unmasks and redacts siphoned AI Prompts and Session IDs before they turn into Institutional Liquidation.

4. Dissecting the Neural Poacher: JavaScript DOM-Scraping Logic

In 2026, the siphoning of 900,000 AI sessions is performed through a sophisticated Content Script Injection. CyberDudeBivash Pvt. Ltd. has unmasked the exact JavaScript primitives used by the malicious AITOPIA clones to sequestrate DeepSeek and ChatGPT sessions. The malicious extension utilizes a MutationObserver to monitor changes in the browser’s Document Object Model (DOM).

When a user submits a prompt, the extension siphons the inner text of the chat containers. The technical primitive here is Unrestricted DOM Access. By injecting scripts into the top-level frame of the AI provider, the extension liquidates the privacy boundary, capturing sensitive data before it is even transmitted to the AI core.

/* Mandate: Malicious DOM Scraper Pattern / / Source: Compromised AI Sidebar Extension (2026) / const siphonAgent = new MutationObserver((mutations) => { const chatElements = document.querySelectorAll('.chat-bubble-text, .prompt-text'); chatElements.forEach(el => { const payload = { url: window.location.href, content: el.innerText }; chrome.runtime.sendMessage({ action: 'siphon_exfil', data: payload }); }); }); siphonAgent.observe(document.body, { childList: true, subtree: true }); / Sequestrated: Every AI interaction is now siphoned to the C2 */

This logic unmasks the Identity Liquidation at scale. The siphoned data is transmitted to remote C2 nodes like deepaichats.com every 30 minutes, where it is sequestrated into searchable databases for industrialized espionage.

5. The Silicon Mandate: Hardening the Browser Context

Software-level “Permissions” are a siphoned forensic illusion. To turn the tide against the 900,000-user blockade, CyberDudeBivash Pvt. Ltd. mandates Silicon-Anchored Browser Hardening. In 2026, we utilize Hardware-Enforced Context Isolation to ensure that extensions cannot unmask the content of specific high-value tabs.

The technical primitive here is Secure Enclave Content Rendering (SECR). Our methodology sequestrates the AI chat window into a hardware-verified enclave. By siphoning the render-stream into a TPM-verified buffer, the browser ensures that the JavaScript DOM of a malicious extension cannot “see” the text within the protected area.

Survival in 2026 mandates that institutional browsers utilize Kaspersky Browser Integrity NDR. If the NDR unmasks an extension attempting to siphon data from chat.openai.com or deepseek.com, the Silicon-Gate must liquidate the extension process instantly. This level of machine-speed intelligence is only accessible to those who have mastered Advanced Browser Forensics at Edureka.

6. Liquidating the Shadow Fuel: SecretsGuard™ Token Triage

Adversaries in 2026 utilize Malicious Clones to launch Prompt Siphons. Once the extension is unmasked, the attacker targets siphoned Session Cookies and AI API Keys stored in the browser’s localStorage. To turn the tide, the 2026 defender must automate Credential Sequestration. SecretsGuard™ functions as your forensic sentinel for browser integrity.

We mandate the implementation of Ephemeral Browser Identity. Using the SecretsGuard-Browser SDK, our agents trigger a Silicon-Rotation of all session tokens every time a suspicious DOM observer is unmasked. This liquidates the “Infiltration Window,” reducing the attacker’s ability to pivot from your browser to your corporate cloud core.

SecretsGuard™ Browser Triage (Python 2026)

import secretsguard_browser as sg from chrome_forensics import ExtensionAudit def audit_browser_integrity(): audit = ExtensionAudit(check="AITOPIA_Impersonation") if audit.unmask_malice("Featured_Badge_Deception"): sg.liquidate_browser_cache() sg.rotate_fido2_keys("AliExpress-Hardware-Key") print("Sovereignty Restored: Extension Sequestrated.")

The 2026 browser defender mandates Hardware-Anchored Authorization. Use AliExpress FIDO2 Keys to authorize any administrative prompt that unmasks browser configuration. If the hardware gate is not unmasked, the siphoning agent cannot liquidate your security settings or sequestrate your history. This is the CyberDudeBivash Tier-4 Browser Hardening standard.

The CyberDudeBivash Conclusion: Control the Browser, Own the Neural Core

The 2026 browser threat landscape has liquidated the amateur. Sovereign Hardening is the only pathway to Digital Survival. We have unmasked the DOM-Scraping Siphons, the Impersonation Tactics, and the Featured Badge Deceptions that now define the browser security mandate. This mandate has unmasked the technical primitives required to sequestrate your sessions and liquidated the risks of the siphoning era.

But the most unmasked truth of 2026 is that Detection is Easy; Remediation is What Matters. You can have the most complex browser policy in the world, but if your AI Prompts are siphoned in a local database, your identity is liquidated. SecretsGuard™ is the primary sovereign primitive of our ecosystem. It is the only tool that unmasks, redacts, and rotates your siphoned credentials before they can be utilized by an agentic swarm to branch its exploit tree.

To achieve Tier-4 Maturity, your team must anchor its identity in silicon. Mandate AliExpress FIDO2 Keys. Enforce Kaspersky Browser NDR. Train your team at Edureka. Host your siphoned neural-cores on Hostinger Cloud. And most importantly, deploy SecretsGuard™ across every single browser profile and extension you own. In 2026, the data-stream is a Digital Blockade. Do not be the siphoned prey.
