Guided Lab: Achieving Code Execution via LLM Output
A hands-on guided lab demonstrating how to bypass blocklists and achieve RCE by tricking an LLM into generating alternative shell payloads via connected tools.

Frequently Asked Questions
How can an LLM lead to remote code execution?
If an app executes model-generated code or commands without isolation, an attacker can prompt the model to output a malicious payload. The application then runs it with its own privileges.
Why do blocklists fail against LLM-generated commands?
Attackers can obfuscate commands with encoding, quoting or alternate binaries so the blocklist misses them. Allowlists, sandboxes and least privilege are more reliable than pattern matching.
Is the lab safe to practise?
Yes. It is a controlled guided lab where you test shell evasion against a deliberately vulnerable setup. It is free and hands-on on Codelivly, with no real systems at risk.
