Brinztech Alert: The Alleged Customer Database of Kimia Market is Leaked

Dark Web News Analysis

The dark web news reports a critical data privacy and infrastructure incident involving Kimia Market (kimiamarket.co.id), a prominent Indonesian supplier of industrial, food-grade, and cosmetic chemicals. A threat actor on a hacker forum is claiming to have leaked a multi-part database containing highly sensitive operational and customer data.

The compromised dataset is extensive and structurally revealing. It reportedly includes three core SQL files: transaksi.sql (containing 352,000 rows of transaction histories), tbl_sessions.sql (containing 1.4 million rows of session data), and customer.sql (containing 20,553 rows of registered user data). The exposure of raw .sql files suggests a severe backend compromise, potentially stemming from an SQL Injection vulnerability or a misconfigured database backup server left exposed to the public internet.

Key Cybersecurity Insights

Breaches involving active session tokens and transactional histories are “Tier 1” e-commerce threats because they provide attackers with multiple avenues for immediate financial exploitation:

• The Session Hijacking Threat: The exposure of the tbl_sessions.sql file is the most immediate technical danger. This file contains the unique Session IDs assigned to users currently or recently logged into the platform. Attackers can inject these valid tokens into their own browsers to hijack active sessions. This allows them to bypass authentication completely—including passwords and Multi-Factor Authentication (MFA)—and take over the victim’s account as if they had logged in legitimately.+1
• Transaction-Based Fraud: The transaksi.sql file exposes 352k rows of Transaction IDs and Dates. Cybercriminals can use this granular data to commit sophisticated refund fraud, or launch highly convincing Business Email Compromise (BEC) attacks targeting B2B clients by referencing exact past orders to demand “unpaid” invoices.
• Customer PII & “Smishing”: The customer.sql dump exposes the Personally Identifiable Information (PII) of over 20,000 customers, including Names, Phone Numbers, and Addresses. In Indonesia, phone numbers are frequently targeted for Smishing (SMS Phishing). Attackers can send texts claiming an issue with a specific Kimia Market delivery, tricking victims into clicking malicious links.
• Supply Chain Intelligence: Because Kimia Market supplies chemicals to other businesses (cosmetics, food production, industrial), this leak also acts as a B2B intelligence goldmine. Competitors or threat actors can analyze the purchasing habits of Kimia Market’s clients to map out local manufacturing supply chains.

Mitigation Strategies

To protect customer accounts and secure the e-commerce infrastructure, the following strategies are recommended:

• Session Invalidation: The IT team must immediately terminate and invalidate all active user sessions on the web server. This neutralizes the 1.4 million leaked session IDs, forcing all users to re-authenticate securely.
• Password Reset & MFA Enforcement: Mandate a global password reset for all 20,553 registered customers. Enforce Multi-Factor Authentication (MFA) for all administrative and high-privilege accounts managing the backend database.
• SQL Vulnerability Audit: Conduct an urgent penetration test focusing on the web application’s input sanitization to identify and patch the specific SQL vulnerability that allowed the database to be dumped.
• Customer Communication: Notify all affected users transparently. Advise them to be on high alert for phishing emails or WhatsApp messages referencing their past Kimia Market orders.
