🚨 PREVENTIVE CYBER INTELLIGENCE ALERT: ALLEGED MASSIVE LEAK OF TAX AND SOCIAL SECURITY DATA — AFIP / ANSES (ARGENTINA) 🇦🇷

[STATUS: UNVERIFIED / HIGH RISK OF TAX FRAUD AND IDENTITY THEFT / POSSIBLE SALE OF DATABASES]

Through the monitoring of threat intelligence tracking platforms, three new incidents were detected on May 25, 2026, registered consecutively (Cases #6528, #6529, and #6530). The threat actor, identified as sergio87, claims to have exfiltrated highly sensitive databases belonging to the main tax collection and social security agencies of the Republic of Argentina.

🎯 Alleged Affected Entities:

Federal Administration of Public Revenue (AFIP) - Monotributo Registration Certificate / PUC Registry.

National Social Security Administration (ANSES) - Social Security (Health Insurance / Pension Data).

RCA (Possibly related to City/Province Revenue Collection or Registries) - Argentine Taxpayer Identification Number (CUIT).

👤 Threat Actor: sergio87.

📂 Claimed Volume: Case #6530 (AFIP) explicitly specifies 20,000,000 records.

⚙️ Incident Type: Alleged Exfiltration and Sale of Government Databases.

📊 TECHNICAL BREAKDOWN AND POTENTIAL RISKS
If these data dumps turn out to be authentic and up-to-date (and not compilations of old breaches like the Renaper one or other previous hacks of state agencies), the impact at the national level is systemic:

🧾 AFIP (Monotributo Certificate / PUC Registry):

The Single Taxpayer Registry (PUC) is the core of tax identification in Argentina. The exposure of 20 million records entails a massive leak of CUIT/CUIL numbers, full names, tax addresses, billing categories, economic activities, and debt status.

Financial Risk: This would facilitate the issuance of fraudulent invoices, tax identity theft, and the extortion of taxpayers with irregularities.

🏥 ANSES (Social Work / Health Insurance):

ANSES data exposes employment history, family allowances, retirement status, and health insurance affiliations (CODEM).

Risk: Data cross-referencing for precise socioeconomic profiling—ideal for telephone scams (known as the "Cuento del Tío" or "Uncle's Tale") targeting retirees by promising retroactive payments or changes in health insurance coverage.

🪪 CUIT (Taxpayer Identification Number):

Massive and structured access to CUITs (Case #6528) allows criminals to automate the creation of fake profiles on digital wallets (Fintechs) and cryptocurrency exchange platforms, or to apply for pre-approved loans by impersonating the victim.

🛡️ MITIGATION AND PREVENTIVE RECOMMENDATIONS

🛑 Alert to Financial Institutions: Banks and Fintechs in Argentina must heighten their biometric validation standards (Liveness Detection) for account opening and online loan applications, operating under the assumption that static data—specifically CUIT/CUIL numbers and addresses—is completely compromised and available to the general public.

🔒 Traffic Auditing (Public Sector): The National CERT, in conjunction with the SOC teams at AFIP and ANSES, must urgently review access logs for their APIs (particularly those utilized by provincial governments, municipalities, or health insurance providers) to detect any recent instances of massive data extraction (Data Scraping). ⚡ MONITORING AND EVALUATION

Great book!

[Phil Eaton @eatonphil]

I first tried to read this book in 2018 and couldn't make it through because I thought it was too hard.

8 years later it's the only book I recommend every developer reads, and I had the chance to review the 2nd edition.

Join a study group, give it a read.

I rejected and she was confused

"I've never been hacked"

99% of people are not aware any account probably can and will be hacked on a long enough timespan

The best security is NOT storing sensitive data ever
