Full breach record for TransUnion →13 incidents on file

Maine AG data breach notice filed listing TransUnion as the entity. The form reports 51 persons affected total (19 Maine residents) from an 'Internal system breach.' Form fields are internally inconsistent: breach date listed as Sept 19 2022, discovery date as 08-20-2009, and consumer notification date as July 13 2009 — these dates pre-date the breach date and suggest data-entry errors in the submission. The submitter is identified as a 'Consumer' (Trustee), not a TransUnion representative, further reducing reliability. No data categories acquired were specified; no identity-theft-protection services offered.
