On February 19, 2025, Indonesian IT solutions provider Next TI appeared on the leak site of the fog ransomware group in a listing claiming internal files were exfiltrated during a ransomware attack.

What Public Reporting Shows
Public reporting indicates that Next TI, which builds financial digital platforms for banking and multifinance companies and is backed by South Korea’s Hana Financial Group, had data taken by the attackers. The fog ransomware group listed the company on its leak site that same day. Available reporting describes the exposed material as internal files exfiltrated during the ransomware incident. The exact number of people whose information was contained in those files remains unknown. No confirmed list of specific data types such as customer names, account numbers, or employee records has been published by the group or independently verified.
Why This Matters for You and Your Family
When a company that handles financial technology platforms suffers a breach, the information inside its systems can include personal details that reach far beyond the company itself. If you or your family bank with institutions that use Next TI’s platforms, your data may have been present in the internal files taken. Credential leaks from such incidents often surface later on criminal forums, giving thieves the raw material they need to attempt account takeovers on your bank accounts, email, or other services where the same password was reused. For ordinary families this can mean sudden loss of access to money, fraudulent loans taken in your name, or months of cleaning up damaged credit. Children’s information linked to a parent’s work or banking records can also be exposed, creating long-term risks.
The Doxxing and Identity-Chain Implications
Ransomware groups rarely stop at encrypting computers. Once they exfiltrate files they frequently publish samples or sell the full dataset. This creates a chain reaction: an email address found in the Next TI files can be cross-referenced with gaming accounts, social-media handles, and family addresses. Attackers then use these links to dox individuals, harass family members, or launch spear-phishing campaigns. Credential leaks like this one regularly cascade into account takeovers precisely because people reuse passwords across work systems, personal email, and children’s gaming logins. A single breach can therefore expose an entire household’s digital footprint.
