SQLULDR2

SQLULDR2 is a tool used by the APT41 DUST cluster to gather local system and database information and to collect data from victim Oracle databases. In the described activity, APT41 DUST used SQLULDR2 as part of a broader intrusion focused on Oracle database theft: data was collected from Oracle databases using SQLULDR2, exported to local CSV files, compressed with RAR, and then exfiltrated to OneDrive. The reporting directly associates SQLULDR2 with automated collection from compromised environments and specifically with Oracle database data extraction. It is mentioned alongside PINEGROVE as part of APT41 DUST tooling. High-confidence context ties its use to APT41 DUST operations that also employed HTTPS-based command and control, Cloudflare infrastructure or Cloudflare Workers, compromised Google Workspace accounts, web shells such as ANTSWORD and BLUEBEAM, and malware including DUSTPAN and DUSTTRAP. The content does not provide standalone technical details such as platform support, persistence, or specific file indicators for SQLULDR2 itself beyond its role in gathering local system and Oracle database information.
