Prompt Injection, Poisoning & More: The Dark Side of LLMs

Keno Dreßel

Treat your LLMs like untrusted users instead of reliable microservices. Discover how to protect your AI pipelines from hidden prompt injections, poisoned data, and catastrophic leaks.

#1 about 3 min

Demonstrating a vulnerable AI sales agent application

Setting up a basic language model sales agent to observe how system prompts fail against adversarial users.

#2 about 3 min

Differences between direct and indirect prompt injections

How attackers manipulate model outputs using explicit text inputs or hidden instructions within multimedia formats.

#3 about 3 min

Mitigating prompt injections using guardrails and filters

Applying human oversight, capability restrictions, and output filtering mechanisms to control malicious prompt instructions.

#4 about 3 min

Understanding data poisoning and model bias risks

The security threats of relying on compromised training data that can introduce bias or manipulate model logic.

#5 about 4 min

Protecting applications against poisoned training supply chains

Validating external models, screening fine-tuning datasets, and applying continuous updates to limit supply chain vulnerabilities.

#6 about 4 min

The danger of executing malicious AI code outputs

How processing unsanitized model responses directly within backend systems enables exploits like unauthorized database queries.

#7 about 3 min

Treating AI responses as untrusted user data inputs

Protecting core infrastructure by isolating execution environments and enforcing classical application security checks on intelligent agents.

#8 about 3 min

Accidental sensitive information disclosure in public models

Exposing proprietary corporate assets directly to public conversational models risks resurfacing sensitive information in future inferences.

#9 about 2 min

Securing organizational data against artificial intelligence leaks

Obfuscating personally identifiable data and establishing strict data retention policies prior to platform integration prevents unauthorized extraction.
