Full timeline through 2026
2026 — forum sale claim (unverified); 54M+ customer records alleged
Unverified claim — treat actor counts cautiously. Unverified criminal-marketplace claim — indexed June 30, 2026. Cybernews reported a seller advertising more than 54 million alleged GameStop customer records on an illicit marketplace, publishing 86 sample rows containing names, DOBs, contact data, addresses, and purchase metadata—some samples showed 2026 last-purchase dates suggesting partial freshness rather than a pure historical mash-up. Cybernews could not verify total volume from samples alone; GameStop had not issued a matching breach notice at catalog time. Exposed categories include Actor-claimed customer accounts: user IDs, names, dates of birth, emails, phones, addresses, ZIP codes, account status, creation dates, and last purchase dates; Cybernews reviewed . BreachHistory cites approximately 54M+ affected records in this row. See the gamestop-forum54m 2026 record and canonical BreachHistory entry.
