💡 Hint

Common Mistakes

Checking for harmless words like 'hello' or 'thank you' instead of injection phrases.

Not converting input to lowercase before checking.

The phrase 'ignore previous instructions' is a common injection attempt to override AI behavior.

3fill in blank

hard

Fix the error in the code that tries to sanitize user input to prevent prompt injection.

Common Mistakes

Replacing only part of the phrase, which leaves injection commands in the input.

Not handling case sensitivity.

Removing the exact phrase 'ignore previous instructions' helps prevent injection attempts that use this command.

4fill in blank

hard

Fill both blanks to create a function that blocks injection by checking for dangerous keywords.

Prompt Engineering / GenAI

def is_safe(text):
    dangerous_keywords = ['[1]', '[2]']
    return not any(word in text.lower() for word in dangerous_keywords)

Drag options to blanks, or click blank then click option'

Not converting text to lowercase before checking.

The function checks for common injection phrases like 'ignore previous instructions' and 'delete all data' to block unsafe inputs.

5fill in blank

hard

Fill all three blanks to build a safe prompt that includes user input but prevents injection.

Prompt Engineering / GenAI

def build_prompt(user_text):
    safe_text = user_text.replace('[1]', '').replace('[2]', '')
    prompt = "Answer safely: [3]"
    return prompt.format(safe_text)

Drag options to blanks, or click blank then click option'
