  • 20 Million User Data of French Citizens
  • 20 Million User Data of Turkish Citizens
  • 10 Million User Data of Russian Citizens
  • Over 11 Million User Data of UK Citizens

Cybernews researchers contacted the threat actor who shared the post and requested a data set sample as evidence to confirm the relevant leak. In the shared example, there are phone numbers of 1097 UK and 817 US users. However, the threat actor did not provide details on how the database was obtained, suggesting that they used their strategies to collect the data. Upon this, the analysis of the sample data set by Cybernews researchers confirmed that all numbers belong to active WhatsApp users.
