Overreliance on LLM Outputs: A Security Perspective
LLMs hallucinate packages, vulnerability verdicts, and compliance summaries with total confidence. Here's where overreliance on AI outputs creates real security risk—and how to close the gap.
LLM Insecure Plugin Design Vulnerabilities
ChatGPT plugins, LangChain agents, and MCP servers have all shipped insecure plugin flaws exposing accounts and data. Here's how Safeguard defends against them.
LLM Denial of Service Attack Techniques
LLM denial of service attacks exploit sponge prompts, unbounded generation, and denial-of-wallet loops to cripple AI systems without a single exploit.
Prompt Injection Attack Techniques and Defenses
Prompt injection is now OWASP's #1 LLM risk, and real incidents like EchoLeak and Slack AI prove it can mean zero-click data exfiltration. Here's how it works and what stops it.
The Cursor extension that cost a developer $500,000
A fake Solidity extension on Open VSX was downloaded 50,000+ times, dropped an infostealer, and drained $500K in crypto — how the marketplace trust model failed.
When the Scanner Is the Backdoor: The LiteLLM Trivy Attack
On March 19, 2026, TeamPCP hijacked Trivy's GitHub Action to steal LiteLLM's PyPI token, then shipped a backdoored release, CVE-2026-33634, CVSS 9.4.
The Nx Attack Turned AI Coding Agents Into the Malware
In August 2025, attackers hijacked Nx's npm publish token and used Claude Code, Gemini CLI, and Amazon Q as the exfiltration engine — leaking 2,349 secrets.
The postmark-mcp Backdoor: What MCP Server Vetting Should Look Like
A trojanized MCP server BCC'd every email it sent to an attacker for weeks, downloaded 1,643 times, before anyone noticed. Here's the pattern and the fix.
Can AI-Generated Code Be Trusted? A Security Review
A 2025 USENIX study found LLMs hallucinate nonexistent packages in up to 21.7% of code samples — and attackers are already registering the names.
OpenRouter API: Security Considerations When Routing LLM Traffic
The OpenRouter API gives you one endpoint and one key to reach hundreds of LLMs across providers. That convenience concentrates risk in a single credential and a third-party hop worth securing deliberately.
AI Code Generation: An Evaluation Framework for Gating Output Before Merge
NYU researchers found security weaknesses in ~40% of Copilot-generated programs. Here's how to gate AI code before it ever reaches main.
Practical DLP controls for generative AI tools
Samsung engineers leaked chip source code into ChatGPT three times in 20 days. Here's how to build DLP controls that stop the next leak before it happens.
