175K Exposed Ollama Hosts Allow Remote Code Execution
cyberpress.org/175k-expo…
A massive global network of 175,000 publicly exposed Ollama AI servers, posing
significant remote code execution risks across 130 countries.
An unmanaged layer of AI compute infrastructure operating without the security
guardrails and monitoring systems that major platform providers implement by
default.
Over a 293-day scanning period, researchers identified 7.23 million
observations from unique Ollama hosts spanning 130 countries and 4,032
autonomous system numbers.
The infrastructure analysis revealed a persistent core of approximately 23,000
hosts that generated most of the activity, while a larger layer of transient
hosts appeared briefly before disappearing.
Nearly half of the observed hosts are configured with tool-calling
capabilities that enable them to execute code, access APIs, and interact with
external systems.
