CDEK Users Emails Have Been Published
In early 2022, there is much serious news related to Russia. An organization known as IT Army published over 30GB of data allegedly sourced from Russian courier service CDEK. The hackers said their goal isn't money, they want to expose over 100 GB of database to completely de-anonymize most Russian users.

Breach Detail
No report from CDEK confirmed when or how this leakage happened, and the authenticity of the breach could not be independently established. So the breach now is set as unverified.

IT Army didn't prove their data from CDEK and didn't hint any clues for the other 70 GB data they promised. The currently published data contained over 19M unique email addresses along with names and phone numbers. If we consider the business type of CDEK, the real address is probably leaked together.

If you are a user of CDEK, either sender or recipient, your personal data possibly is published by IT Army. If you have an online account, you have a higher risk.

Below are useful suggestions for CDEK users:
  • Check if your email is published;
  • Change your password with a strong format;
  • Make sure you do not use the same password twice;
  • Change passwords in other accounts that have the same or similar password.
