Klaus_cloud_public 528logs: 14,824 US Credentials — Second Oct 6 Batch, 25,174 Combined
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 realy 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.
