Exposed Kubernetes (K8s) clusters are being exploited by malicious actors to deploy cryptocurrency miners and other backdoors. Cloud security firm Aqua, in a report shared with The Hacker News, said a majority of the clusters belonged to small to medium-sized organizations, with a smaller subset tied to bigger companies, spanning financial, aerospace, automotive, industrial, and security sectors.

The publicly-accessible clusters, per Aqua, are said to suffer from two different kinds of misconfigurations: allowing anonymous access with high privileges and running kubectl proxy with the flags "--address=`0.0.0.0` --accept-hosts `.*`" "Housing a wide array of sensitive and valuable assets, Kubernetes clusters can store customer data, financial records, intellectual property, a
