What it detects

This rule detects an external Salesforce application issuing bulk record queries using a Python-urllib user agent, the data theft pattern of the Klue supply chain attack. The actor drove QueryMore bulk reads against the query API from an external application client using a scripted urllib agent rather than a browser. Bulk querying of Salesforce objects by an external app with a scripting user agent indicates automated data exfiltration.
