## Summary  
The paper surveys large language model (LLM) vulnerabilities across the entire lifecycle and application stack, identifying eight distinct stages where trust boundaries can be breached. It maps each stage to specific attack vectors and security objectives—confidentiality, integrity, availability, safety, privacy, fairness, accountability, and agency‑control—and explains why point‑defense strategies rarely compose. The authors propose a systematic taxonomy that links the full operational chain of an LLM to concrete risks and defense gaps. This work moves beyond isolated attack catalogs toward a holistic view of secure LLM deployment.

## Key Contributions  
- [Finding 1] A comprehensive eight‑stage lifecycle framework that links each stage of LLM operation to specific attack vectors and trust failures.  
- [Finding 2] Mapping of LLM‑specific vulnerabilities to confidentiality, integrity, availability, safety, privacy, fairness, accountability, and agency‑control objectives.  
- [Finding 3] Emphasis on compositional security and the need for provenance‑aware retrieval and tool‑call containment.

## Methodology  
The authors conducted a systematic literature review of research papers, technical reports, and industry case studies published up to June 2026. They extracted attack categories per stage, evaluated their practical risk level, and surveyed existing defenses. The analysis is organized into a table‑like structure that groups attacks by stage, security objective, and mitigation approach.

## Results  
The survey identifies high‑risk stages such as data collection (privacy leaks), post‑training alignment (adversarial prompting), tool/agent execution (code injection), and deployment/maintenance (supply‑chain compromise). It also notes gaps in evaluation practices—most studies focus on isolated attacks rather than end‑to‑end trust. Theoretical insights include that untrusted data becomes executable instruction, amplifying model errors across the stack.

## Significance  
This work moves beyond ad‑hoc attack catalogs to a holistic view of LLM security, guiding developers and auditors toward layered defenses and long‑term governance. It informs policy on agency control and fairness in autonomous agents by highlighting where trust boundaries fail and why point defenses rarely compose.
