2 million files from the French Office of Immigration were found for sale on the dark web.

Omissions

• The figure of '2 million' appears in Le Monde's reporting; other sources cite 2.1 million entries — the difference is within rounding tolerance.
• The data was published on BreachForums, a dark web forum where stolen data is commonly traded. While the hacker published samples and claimed to possess the full dataset, it remains unclear whether the entire dataset was formally listed 'for sale' or simply published as a proof-of-breach.
• At the time of the MEP's speech (17 June 2026), the investigation opened by the Paris prosecutor's office on 8 January 2026 was still ongoing, and the full extent of the breach had not been independently confirmed by authorities beyond the hacker's claim.
• All available sources are secondary (journalistic); no primary official confirmation from OFII or French authorities regarding the exact number of files was publicly available by the session date.
