Thingiverse's owner, MakerBot, is aware of the incident but at the time of writing, is yet to issue a disclosure statement. The data was provided to HIBP by dehashed.com.
In September 2021, a publicly accessible PostgresSQL database belonging to the Playbook service was identified. Run by VC firm Plug and Play Ventures, the database had been exposed since October 2020 and contained more than 50 thousand unique email addresses along with names, phone numbers, job titles and passwords stored as PBKDF2 hashes. It took more than 2 weeks after being notified of the exposed data to properly secure it.

During the first half of 2021, LinkedIn was targeted by attackers who scraped data from hundreds of millions of public profiles and later sold them online. Whilst the scraping did not constitute a data breach nor did it access any personal data not intended to be publicly accessible, the data was still monetised and later broadly circulated in hacking circles. The scraped data contains approximately 400M records with 125M unique email addresses, as well as names, geographic locations, genders and job titles. LinkedIn specifically addresses the incident in their post on An update on report of scraped data.
