## Klaus_cloud_public's Second Strike: 528logs and 28.1 Records Per File Klaus_cloud_public's 528logs release on October 6, 2023 is the operator's second confirmed dataset from that day -- following the earlier 351logs batch (10,350 records at 29.5/file). Together they push Klaus_cloud_public's Oct 6 total to 25,174 records, making it the fourth-largest individual operator on the day by combined volume. What's really notable about Klaus_cloud_public is consistency: both batches clock in at near-identical per-file yields (29.5 and 28.1 respectively), a pattern that suggests a stable, high-quality source of infected endpoints rather than opportunistic collection. --- ## Klaus_cloud_public 528logs (Oct 6, 2023): Stealer Log Summary - **Records Exposed:** 14,824 - **Data Types:** Email addresses, plaintext passwords, URLs - **Breach Type:** Stealer log -- credentials harvested from malware-infected endpoints, not a direct database breach - **Password Type:** Plaintext -- captured directly from browser sessions and credential stores by infostealer malware - **Country:** United States - **Date Leaked:** October 6, 2023 --- ## Per-File Yield: Klaus_cloud_public vs. the Oct 6 Operator Field Among all confirmed Oct 6 operators, Klaus_cloud_public 351logs holds the day's highest per-file yield at 29.5 records/file. The 528logs batch (28.1/file) sits just below -- still comfortably ahead of Usmancloud 733logs (28.0/file), BananaLogs 495count (18.5/file), and the SunCloudPubl batches.
