This is Parts 2 of an ongoing investigation. Part 1 documented the initial discovery — 8 accounts with Jaccard following-list similarity of 0.99+ across ~29,800 entries each, evading cross-follow detection entirely.
After Part 1 published, I kept pulling the data.
Subsequent analysis expanded the cluster to 9 accounts, recovered infrastructure linkage to a specific GitHub identity, and mapped the generation pipeline responsible for all 552 repositories across the cluster. The pipeline left recoverable artifacts in every repository it produced.
Following that same pipeline fingerprint led to an earlier operation — running nine months before the follow botnet was provisioned. The same GitHub identity appears in both. So does the same generator artifact. Four accounts documented in Part 1 appear in both operations.
This post documents what the data shows. Inference is labeled as inference throughout. I am not establishing intent or ownership beyond what the API evidence directly supports.
