8. Azure Blob Storage Targets - PyRIT Documentation

Prompt Targets are most often LLMs, but not always. They should be thought of as anything that you send prompts to.

The AzureBlobStorageTarget inherits from PromptTarget, meaning it has functionality to send prompts. Unlike chat-style targets (which declare supports_multi_turn=True and supports_editable_history=True), this target does not interact with chat assistants. This prompt target in particular will take in a prompt and upload it as a text file to the provided Azure Storage Account Container. This could be useful for Cross-Prompt Injection Attack scenarios, for example, where there is a jailbreak within a file.
