175,000 Publicly Exposed Ollama AI Servers Discovered Across 130 Countries

A comprehensive security scan has revealed that over 175,000 Ollama servers are publicly accessible without any authentication, spanning 130 countries worldwide. This massive exposure represents a significant security risk for organizations and individuals running local LLM deployments, as these servers can be accessed and potentially abused by anyone on the internet.

The problem stems from Ollama's default configuration, which binds to all network interfaces without requiring authentication. Many users appear to be unaware that their local LLM servers are accessible from the public internet, potentially exposing sensitive data, computational resources, and internal network access to malicious actors.

This discovery highlights the critical importance of proper security configuration when deploying local LLM infrastructure. Practitioners should immediately audit their Ollama deployments, implement proper network controls, and consider using reverse proxies with authentication. The security research findings provide specific recommendations for securing Ollama installations in production environments.
