Breach Database / NemoWeb

Yes — NemoWeb was breached.

What happened

In September 2016, almost 21GB of data from the French website used for "standardised and decentralized means of exchange for publishing newsgroup articles" NemoWeb was leaked from what appears to have been an unprotected Mongo DB. The data consisted of a large volume of emails sent to the service and included almost 3.5M unique addresses, albeit many of them auto-generated. Multiple attempts were made to contact the operators of NemoWeb but no response was received.

What data was exposed

What to do right now

  1. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  2. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  3. Monitor the apps you use going forward. Clearly watches the breach record for the companies behind your apps and alerts you the moment one appears.
