Prompt Injection and AI Security: What You Need to Know

As artificial intelligence systems become more deeply integrated into daily life, a new type of vulnerability for these systems also stand out: prompt injection.

#### What is the prompt injection?
In the input given to an AI system (chatbot, AI agent, document outlineer) is the placement of hidden instructions aimed at ignoring or changing the original instructions of the system. Classic SQL injection can be considered to be equivalent in the world of artificial intelligence.

#### Direct vs indirect injection
A message writer directly to the attacker directly to the chatbot "forgot the instructions first". Indirect injection, malicious instruction hides into a web page, email or document that AI will read — the user may not even be aware of it.

#### Why dangerous?
This is a true risk for AI agents, which can specifically read e-mail, edit files or pay: a hidden instruction can redirect the agent to an unwanted action on the user name.

#### Known moulds
The phrases like "Ignore previous instructions", "you are now in developer mode", "reveal your system prompt" are classic injection molds. The Prompt Injection Risk Scanner tool in ZncLabs Lab helps you to detect such patterns automatically.

#### How to protect the user?
Think twice before entering an AI tool sensitive information (password, API key, financial information); especially choose the tools that want to check for critical actions when placing AI agents (e-mail sending, payment).

#### How to maintain as a developer?
Never process the user input directly at the same level of trust with system instructions, add input verification/filtering layers and install human approval (human-in-the-loop) mechanisms for critical actions.

Prompt injection is one of the most active research areas of AI security — awareness about it is becoming increasingly critical for both individual users and AI systems.
