This Is Already Happening
These aren't hypothetical threats. Every finding below comes from public research published in the last 90 days.
19 npm packages with hidden backdoors targeting Cursor, Claude Code, and Windsurf
Malicious packages in the npm registry specifically targeted developers using AI coding assistants, injecting backdoors into agent workflows.
Socket Threat Research, Feb 202621 of 36 documented attacks exploit 4+ stage kill chains
The majority of real-world AI agent attacks chain multiple vulnerabilities together, making single-point defenses insufficient.
Brodt, Feldman, Schneier, Nassi — “The Promptware Kill Chain,” Jan 2026Only 14.4% of organizations report all agents go live with full security approval
The vast majority of AI agent deployments bypass security review entirely, creating blind spots across identity, access control, and observability.
Gravitee API Security Report 202656 Pages. 9 Chapters. Everything You Need.
From threat landscape to implementation checklists. Every claim backed by a data point, CVE, academic paper, or named incident.
The AI Agent Threat Landscape
Deployment scale, governance gaps, and why agents are fundamentally different from traditional software. Includes Aguara Watch observatory data.
The Promptware Kill Chain: 7 Stages
From initial access to actions on objective. Each stage mapped to real attacks: Morris II, ZombAI, SANDWORM_MODE, SpAIware, and more.
OWASP Agentic Top 10
All 10 risks with real-world exploitation examples: goal hijacking, tool poisoning, memory corruption, privilege escalation, and inter-agent attacks.
Credential Security for AI Agents
23.8M secrets leaked on GitHub in 2024. AI-assisted repos leak 40% more. Hardcoded keys in 10.9% of scanned skills. Credential lifecycle for agents.
Supply Chain Security
Two distinct supply chains: data and tool. Rug-pull attacks, typosquatting, config injection (CVE-2025-59536), and the SANDWORM_MODE worm dissected.
Regulatory and Standards Landscape
OWASP, NIST NCCoE, MITRE ATLAS, Cloud Security Alliance, OpenSSF. What each framework requires and where they converge.
Defense-in-Depth Framework
Three deployment layers: static analysis before deployment, runtime isolation to contain breaches, runtime enforcement to detect and block attacks.
Implementation Checklists
7 actionable checklists: MCP hardening, secrets management, container security, code review, rug-pull detection, SIEM rules, argument validation.
