  • All internal databases.
  • Customer financials.
  • Passports.
  • Account balances.
  • Accesses to personal accounts of Companies House customers of Xeinadin.
  • Client legal information.
  • And much more.

The gang threatens to publish the data if the company does not contact them within the deadline of 25 December 2023.

“We suggest Xeinadin management to contact us and correct their mistakes, preventing a huge leak of customer data. If in 72 hours management does not realize the severity of the situation and contact us, we will publish the legal, tax, financial and other private data of hundreds of companies from England and Ireland here.” reads the message published by the ransomware group on its Tor leak site.
