Something similar happened at a previous employer. Contractor was hired to do a big data PoC, and they managed to cajole access to a prod data dump for a more impactful demo.

They then managed to load all this PII data into an ElasticSearch instance that was open to the internet and was discovered by threat actors.

I wouldn’t be surprised to find that something similar happened here, where an unscrubbed prod dataset was shared for a better demo.
