Breach Database / CDEK

Yes — CDEK was breached.

What happened

In early 2022, a collective known as IT Army whose stated goal is to "completely de-anonymise most Russian users by leaking hundreds of gigabytes of databases" published over 30GB of data allegedly sourced from Russian courier service CDEK. The data contained over 19M unique email addresses along with names and phone numbers. The authenticity of the breach could not be independently established and has been flagged as "unverified".

What data was exposed

What to do right now

  1. Be alert for smishing and SIM-swap attempts. Treat unexpected texts and "carrier" calls with suspicion; add a PIN/port-freeze with your mobile carrier.
  2. Expect convincing phishing emails. Attackers use breached details to write personalized emails. Be suspicious of any message referencing this service.
  3. Check your other accounts on Have I Been Pwned. Your email address may appear in other breaches you don't know about yet.
  4. 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.
