Prompt injection is rapidly emerging as one of the most critical threats in generative AI. By exploiting the way chatbots interpret prompts, attackers are turning friendly AI interfaces into covert entry points.
This blog breaks down how these attacks work, examples from the wild, and how to defend your organisation.
What Is Prompt Injection?
Prompt injection occurs when a malicious actor embeds harmful instructions in chatbot inputs or content the bot consumes.
Recent Findings:
Remote shell access was achieved with simple chatbot prompts (e.g. ls -la /app).
Credential exposure via hidden prompts embedded in content.
Persistence via cron jobs and stealth Python modules, surviving container restarts.
These attacks were detected across industries like finance and healthcare—where LLMs often process sensitive data.
Defence Strategies
Securing your AI stack means implementing layered protections:
Sanitise user inputs to catch suspicious phrasing.
Partition system prompts from user data.
Limit agent permissions using least-privilege access.
Log and monitor agent behaviour for anomalies.
Human review gates for critical functions.
As AI becomes central to your systems, it must be secured like any critical infrastructure.
AWS's Guide to Securing AI Systems
If you’re building or deploying AI agents, consider a security audit for prompt injection vulnerabilities. The cost of prevention is far lower than post-breach response.
