On October 16, claims emerged on the social platform X that approximately 24 million Mercari customer records were being sold on the dark web. Currently, neither the authenticity of the data for sale nor its origin from Mercari has been verified.
Circulating posts claim that Dark Web Informer previously listed related sale information with a price tag of $400. The seller claimed the data included names, addresses, phone numbers, and transaction records; another repost also mentioned email addresses, completed transactions, canceled purchases, product listings, and earnings. These fields are all derived from restatements of the seller's claims.
The available information does not provide independent verification of data samples, responses from Mercari, or investigative conclusions. Therefore, the authenticity and source of the data cannot be confirmed, nor can it be concluded that a data breach occurred in Mercari's systems based on this.
