Cisco’s Talos security research team has found over 1,100 Ollama servers exposed to the public internet, where miscreants can use them to do nasty things.

Ollama provides a framework that makes it possible to run large language models locally, on a desktop machine or server. Cisco decided to research it because, in the words of Senior Incident Response Architect Dr. Giannis Tziakouris, Ollama has “gained popularity for its ease of use and local deployment capabilities.”

Talos researchers used the Shodan scanning tool to find unsecured Ollama servers, and spotted over 1,100, around 20 percent of which are “actively hosting models susceptible to unauthorized access.” Cisco’s scan found over 1,000 exposed servers within 10 minutes of commencing its sweep of the internet.
