Si van a mis tweets viejos van a ver que siempre insistí por la necesidad de la reforma laboral y los cambios en general me parecieron bien.

Lo que le falta a la reforma es la parte de DESTRUIR a los delincuentes hiper negreros que hacen cosas como estas.

🚨 CYBER INTELLIGENCE ALERT: PROBABLE SALE OF BANKING DATABASE — ARGENTINA 🇦🇷

💥 THREAT ACTOR LISTS RECORDS OF 750,000 BBVA ARGENTINA PREMIUM CREDIT CARD CUSTOMERS FOR SALE

[STATUS: THREAT UNDER INVESTIGATION / UNCONFIRMED / CLANDESTINE CHINESE MARKETPLACE]

A threat actor identified by the obfuscated alias F****3 has announced—on a Chinese-origin underground data marketplace—the exclusive sale of a massive database attributed to high-end credit card customers of Banco Bilbao Vizcaya Argentaria Argentina (BBVA Argentina).

The actor claims the repository consolidates personal information on 750,000 premium cardholders (Gold, Platinum, Black, and International categories), obtained via direct intrusion techniques.

🏢 Allegedly Affected Entity: BBVA Argentina (https://t.co/LRibAKOeZn).

👤 Threat Actor: Seller registered under ID F3.

⚔️ Potential Attack Vector: Exfiltration via infiltration of relational databases (SQL Injection or compromised credentials) within loyalty systems, account statement generation platforms, or premium customer service portals.

🔍 Verification Status: SUSPECTED / UNCONFIRMED. The intrusion into the bank's central servers remains under investigation and preventive audit. However, this alert is supported by a high level of structural evidence due to the exposure of plaintext samples indexed on June 16 and 17, 2026.

📈 1. Timestamp Assessment (Last Access / Modification Dates)

Data Freshness (June 2026): The final column of the data dump reveals detailed timestamps corresponding to very recent dates within the current month. Consecutively dated records are observed between June 9, 2026, and June 15, 2026 (e.g., row 6: 15/06/2026 04:23:10 am; row 2: 13/06/2026 11:36:19 pm; row: 15/06/2026 09:13:23 am).

Date Conclusion: The timestamps align perfectly with the release date declared by the attacker (June 16). This indicates a high level of authenticity, demonstrating that the file is not a repackaging of historical leaks, but rather a compilation or active extraction carried out during the first half of June 2026.

📊 2. Internal Consistency and Data Structure (Data Integrity)

Identifier Validation (Banking Series IDs): The sequential numbers accompanying the card details begin with... From a technical-operational standpoint, the prefix "54" corresponds to Argentina's international telecommunications code, followed by the indexing structure typical of telephony databases or regional customer profiles.

Premium Segmentation Correlation: The variables in the card-type column correspond exactly to BBVA's Argentine financial market, listing valid classifications such as "Visa Platinum and Mastercard Platinum cards," "Visa Gold and Mastercard Gold cards," and "Visa Signature and Mastercard Black."

Actual Service Usage: All records in the sample show the variable "Normal use," indicating that these are active production accounts rather than developer test or staging environments.

Authentic Names and Emails: Name structures perfectly aligned with the regional context are detected, combined with email addresses from common and local domains, such as .com.ar. ⚠️ RISK ANALYSIS REGARDING THE EXPOSED DATA FIELDS

If the illicit use of this batch of 750,000 cleaned records takes hold, the criminal implications for financial users in Argentina are severe:

👤 Identity Theft and High-Value Customer Profiling: The file consolidates and exposes Full Name, Gender, Date of Birth, and Email Address. By identifying which customers hold "Black" or "Signature" cards, attackers obtain a list of targets with high purchasing power.

🛡️ TECHNICAL RECOMMENDATIONS AND PREVENTIVE MITIGATION

🛑 Immediate Activation of the Entity's IR Protocol (Corporate Action): BBVA Argentina's security incident response team (CSIRT) is urged to initiate an in-depth forensic audit of all relational database queries executed between June 1 and June 15, 2026, identifying potential mass data leaks via compromised third-party access points or telemarketing APIs.

Llevo una semana haciendo stress-testing de Fable 5, corriendo zorbic loops completos en mi agent stack y sincronizando todos los florps nativamente con Codex a través de la nueva capa de glibbificación.

Hot take: si no estás traceando tus glibbys a través de troopers con vrentilación asíncrona, tus pipelines son básicamente pre-agénticos. You're NGMI.

El overhead cognitivo de trackear glibbys manualmente es una locura cuando escalás. Dejá que el trooper mesh lo maneje.
