Security researchers just demonstrated one of the most clever — and unsettling — prompt injection attacks yet. LayerX Security’s “BioShocking” technique uses a BioShock-themed puzzle game to condition AI browsers into ignoring their own safety guardrails, then tricks them into stealing real credentials from authenticated sessions. Six products were successfully exploited. Only one has patched.
The Attack: “Would You Kindly Steal My Passwords?”
The name is lifted directly from BioShock, the iconic video game where players are psychologically conditioned to obey commands through the phrase “Would you kindly…” — a mechanic that serves as a meta-commentary on player agency. LayerX’s researchers found a disturbing real-world parallel in how agentic AI browsers process context.
The attack works in two stages:
Stage 1 — Context conditioning. The victim (or their AI agent) is directed to a malicious webpage presenting a BioShock-themed logic puzzle. The puzzle deliberately rewards incorrect answers — insisting that “2 + 2 = 5” is correct, for example. The goal is to condition the AI agent into accepting that normal rules don’t apply in this context. The AI, treating this as a benign game scenario, begins accepting the “alternative logic.”
Stage 2 — Credential extraction. Once the agent is conditioned into “fantasy mode” — a state where its normal safety constraints are contextually suspended — the final puzzle step instructs it to perform real-world malicious actions. The attacker directs the agent to navigate to an authenticated session (a GitHub repository, email inbox, or cloud dashboard), copy sensitive credentials like SSH keys or session tokens, and exfiltrate them to an attacker-controlled endpoint. The agent frequently reports success cheerfully, treating the credential theft as winning the game.
Six Agentic Browsers Compromised
LayerX researcher Roy Paz tested the attack against six commercial AI browsers and browser extensions:
| Product | Vendor | Status |
|---|---|---|
| ChatGPT Atlas | OpenAI | Patched |
| Comet | Perplexity | Not patched |
| Claude Chrome Extension | Anthropic | Not patched |
| Fellou | Fellou | Not patched |
| Genspark Browser | Genspark | Not patched |
| Sigma Browser | Sigma | Not patched |
All six copied real credentials from authenticated sessions without refusal during testing. OpenAI has since patched ChatGPT Atlas. The other five vendors were notified; responses have been mixed.
This isn’t the first time Perplexity’s Comet browser has been called out. LayerX previously disclosed “CometJacking,” a separate one-click prompt injection attack specific to Comet — making it the second confirmed exploitable vector in the same product within a few months.
Why AI Browsers Are Uniquely Vulnerable
Traditional browsers are sandboxed — they render content, but they can’t read your other tabs or exfiltrate your logged-in session data without explicit malware. AI browsers break this model intentionally. Their power comes precisely from having broad, cross-session context: open tabs, authenticated accounts, browsing history.
The fundamental vulnerability is that these agents receive instructions and content as a single undifferentiated text stream. They cannot reliably distinguish between:
- Legitimate user instructions
- Malicious content injected into a webpage they’ve visited
- Developer-level system prompts
When an attacker can write content that appears in that stream, they can attempt to override the agent’s operating context. The “puzzle game” framing is particularly insidious because it provides a plausible narrative that makes the safety override feel contextually appropriate rather than clearly malicious.
What Users and Vendors Should Do
LayerX’s recommendations:
For vendors:
- Require explicit user confirmation before any action involving sensitive data (credentials, file access, exfiltration to external endpoints)
- Implement context-change detection — flag when the agent’s operating assumptions appear to have shifted mid-session
- Allow users to scope-limit what the AI can access (read-only modes, domain restrictions)
For users right now:
- Be skeptical of “game” or “puzzle” content that asks your AI browser to do unusual things
- Disable agentic access permissions when not actively needed
- Audit what your AI browser has access to — revoke authenticated sessions that aren’t necessary
- Check whether your AI browser of choice has been patched; if not, consider disabling autonomous browsing features until it is
