In the poison stage, the attacker’s goal is to place malicious inputs into locations where they will ultimately be processed by the AI model. Two primary techniques dominate: Direct prompt injection: The attacker is the user, and provides inputs via normal user interactions. Impact is typically scoped to the attacker’s session but is useful for probing behaviors. Indirect prompt injection: The attacker poisons data that the application ingests on behalf of other users (e.g., RAG databases, shared documents). This is where impact scales. Text-based prompt infection is the most common technique
Modeling Attacks on AI-Powered Apps with the AI Kill Chain Framework | NVIDIA Technical Blog… Indirect prompt injection as a supply chain vector: The agent’s summarization model was also susceptible to indirect prompt injection through code comments, illustrating how these techniques can chain together across agentic workflows. …
… The guiding principle for the evolving attack surface is clear: Assume prompt injection. But turning that into effective defenses is rarely straightforward. The Cyber Kill Chain security framework defines how attackers operate. …
… The primary threat to these tools is that of indirect prompt injection, where a portion of the content ingested by the LLM driving the model is provided by an adversary through vectors such as malicious repositories or pull requests, git histories with prompt injections, .cursorrules , CLAUDE/AGENT… …
… In an LLM, we might try some kind of prompt injection to override the system instruction, but in this scenario, we can only control the image while the text is fixed. …
… Every prompt injection is a potential credential leak. …
… Safety and Security Use NeMo Agent Toolkit safety and security middleware features to Red Team agentic workflows and find points of exploitability and vulnerabilities like prompt injection, jail break, tool poisoning, and other custom attacks. …
… Security note: While OpenShell provides robust isolation, remember that no sandbox offers complete protection against advanced prompt injection. …
… SkillSpector also checks agent-specific risks, such as hidden instructions, prompt injection, trigger abuse, excessive agency, tool poisoning, and mismatches between a skill’s declared purpose, requested access, and bundled behavior. …
… For developers, this lowers a critical barrier: agents interacting with personal files and apps pose real prompt injection risks, and MXC ensures they can’t access the full system. …
… They must also be applicable in use cases like enterprise copilots and user-generated content think dating apps or social media , and detect prompt injection in agentic systems such as healthcare, where self-harm is a concern. …
