Data Poisoning Attacks | Episode 31
In this episode of BHIS Presents: AI Security Ops, the panel dives into the hidden danger of data poisoning – where attackers corrupt the data that trains your AI models, leading to unpredictable and often harmful behavior. From classifiers to LLMs, discover why poisoned data can undermine security, accuracy, and trust in AI systems.

We break down:

What data poisoning is and why it matters
How attackers inject malicious samples or flip labels in training sets
The role of open-source repositories like Hugging Face in supply chain risk
New twists for LLMs: poisoning via reinforcement feedback and RAG
Real-world concerns like bias in ChatGPT and malicious model uploads
Defensive strategies: governance, provenance, versioning, and security assessments

Whether you’re building classifiers or fine-tuning LLMs, this episode will help you understand how poisoned data sneaks in, and what you can do to prevent it. Treat your AI like a “drunk intern”: verify everything.
