Is RealGround the same company as CyberSE.AI?

Yes. RealGround was formerly known as CyberSE.AI. The company rebranded and moved from www.cyberse.ai to www.realground.com; the old domain permanently redirects here. Same team, services, and content.

RealGround is a daily AI security intelligence and advisory platform for SMBs and AI startups deploying LLMs, AI agents, model APIs, and AI-enabled workflows.

What risks does RealGround cover?

RealGround covers prompt injection, indirect prompt injection, AI agent abuse, data leakage, model and supply-chain risk, AI governance, and OWASP-relevant LLM and API security risks.

What is agentic application security?

Agentic application security is the practice of securing AI applications where LLM-based agents autonomously plan, call tools and APIs, read untrusted content, and act on live systems. It covers indirect prompt injection, tool misuse, excessive agency, authorization failures, memory poisoning, and MCP risks.

Who provides agentic application security services?

RealGround is a specialist agentic application security firm offering AI agent security audits, secure agent builds, continuous AI red teaming, AI SBOM mapping, and virtual CISO advisory for SMBs and AI startups.

One Extension Could Hijack AI Assistants Across Chrome, Comet, Edge, Opera Neon and Claude

What Happened

Security researchers at Forever Security have shown that one ordinary browser extension could take control of the AI assistants built into five Chromium-based products: Gemini Live in Chrome, Perplexity Comet, Microsoft Edge, Opera Neon and the Claude in Chrome extension. Once the extension was installed, it could access each product's built-in AI with a single click. On Comet, Edge,

Why It Matters

According to the article summary, researchers at Forever Security demonstrated that a single ordinary browser extension could access and effectively hijack built-in AI assistants across multiple Chromium-based products, including Gemini Live in Chrome, Perplexity Comet, Microsoft Edge, Opera Neon, and the Claude in Chrome extension, once installed and invoked with a click. This indicates a cross-product weakness where browser extension permissions can be used to control or misuse integrated AI assistants, rather than a flaw in any specific model. From a RealGround perspective, this is primarily an AI supply chain risk: organizations relying on browser-based AI assistants are exposed to extension-level compromise, so they should harden extension policies, maintain an AI-focused SBOM and supply chain inventory, and continuously red team browser-based AI workflows to detect unauthorized control paths through extensions.

RealGround Analysis

This signal maps to AI supply chain. Organizations using AI agents, LLM APIs, SaaS integrations, or sensitive data workflows should review whether this class of issue could create unauthorized tool execution, data leakage, weak approval gates, or unmanaged supply-chain exposure.

Recommended Actions

Restrict AI agent tool permissions and production write paths.
Review sensitive data access across prompts, logs, embeddings, memory, and SaaS integrations.
Add human approval workflows for high-impact or state-changing actions.
Run prompt injection and indirect prompt injection tests against affected workflows.
Document the owner, control gap, and remediation deadline for this risk class.
