🚨 CYBER INTELLIGENCE ALERT: ALLEGED COMPROMISE OF FINANCIAL AND TAX INTERMEDIARY — DCI GROUP MEXICO 🇲🇽
[STATUS: SAMPLE VIEWED / UNCONFIRMED / UNDER INVESTIGATION]
Through monitoring of Dark Web forums and leak communities, a post was detected today by the threat actor azazeljakel, operating under the banner of the cybercriminal group CORTEX. The attacker claims to have compromised and extracted the complete database of DCI Group Mexico, a firm that operates as an intermediary in management and collection processes for government entities such as the SAT (Tax Administration Service), the IMSS (Mexican Social Security Institute), and the mortgage portfolio administrator Zéndere.
🎯 Affected Entity: DCI Group Mexico (Third-party intermediary for SAT, IMSS, and Zéndere).
👤 Threat Actor: azazeljackel (Main Alias: azazel) / Group: CORTEX.
📂 Volume Claimed: 240,000 CURPs (Unique Population Registry Codes) and 9,000 mortgage loan files.
⚙️ Vector and Artifacts: A database dump (.sql) and an automated Bash script designed to download PDF loan documents en masse directly from compromised servers.
⚠️ Verification Status: NOT CONFIRMED. The data sample exposes structured, coherent, and accurate information about the management of a real mortgage loan, including valid bank references from BBVA Bancomer, but it has not been confirmed.
📊 TECHNICAL BREAKDOWN OF EXFILTERED FINANCIAL ASSETS
The forensic analysis of the published sample reveals a complete exposure of the asset, identity, and debt data of clients managed by Zéndere's portfolio:
🪪 Personally Identifiable Information (PII):
Full name of the account holder and CURP (240,000 records exposed).
RFC (Federal Taxpayer Registry) of the managing entity.
Collateral Address: Exact physical location of the mortgaged property (Department, Neighborhood, Municipality, State, and Postal Code).
📋 Product and Portfolio Control Data:
Critical internal identifiers: Product ID, Client Number, and Loan Number.
Exact periods of the account statements.
💸 Payment Breakdown and Bank References:
Plain text debt statement: Current Monthly Payment, Amount Due, Collection Fees, and Late Payment Interest.
Financial Fraud Vectors: Payment agreements, unique bank references, and the assigned receiving bank (BBVA Bancomer).
🛡️ MITIGATIONS AND EMERGENCY TECHNICAL RECOMMENDATIONS
🛑 Immediate Blocking of Endpoints and APIs (Kill-Switch): DCI Group and Zéndere must audit and immediately shut down any public APIs or web directories that are allowing the download of PDF account statement documents, as the attacker has distributed an automated script for other criminals to extract this information.
🔒 Customer Fraud Alert (Zéndere / BBVA): Urgently notify the 9,000 affected mortgage customers about the breach. Debtors should be instructed to ignore any phone or email communications requesting emergency payments, changes to receiving accounts, or unsolicited debt restructurings through official channels.
