What it detects

This rule detects DNS queries carrying the structured bt.node.js label suffix to the azurestaticprovider backdoor domain used by the trojanized node-ipc package. The backdoor encodes stolen developer credentials into subdomains resolved through the actor name server for covert exfiltration. DNS lookups matching this domain or the encoded node.js suffix indicate active credential theft over DNS.
