Digimon data breach

Breach date: 2016-09-05. Added to this index: 2018-09-28. Accounts affected: about 7.7M. Domain: digimon.co.in.

What happened

In September 2016, over 16GB of logs from a service indicated to be digimon.co.in were obtained, most likely from an unprotected Mongo DB instance. The service ceased running shortly afterwards and no information remains about the precise nature of it. Based on enquiries made via Twitter, it appears to have been a mail service possibly based on PowerMTA and used for delivering spam. The logs contained information including 7.7M unique email recipients (names and addresses), mail server IP addresses, email subjects and tracking information including mail opens and clicks.

  • Email messages: The content of emails you sent or received, including subject lines, message bodies, attachments and contacts, exposed through a compromised mailbox, an email provider or a company that kept copies.
  • IP addresses: The network addresses your devices used when you signed up, logged in or posted, recorded by almost every website in its access logs.
  • Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
