QRIS (sistema de pagos QR de Indonesia)

A BreachForums thread is distributing what it claims is a database of about 1.5 million QRIS transactions, Indonesia's national QR payment standard used by banks and merchants nationwide. Though outside Latin America, it is a direct example of national payment-rail data being traded openly, which is useful context for defenders of similar systems such as Pix or Mercado Pago. Scale and freshness of the dataset are unverified and should be treated as unconfirmed.

A forum post advertises a 215MB archive from Cia de Trade Philip Morris in Brazil containing PST mailboxes, HR paystubs and credentials for roughly 965 staff. If genuine, it hands attackers working corporate email, payroll and identity data to pivot deeper into the Philip Morris environment and to run convincing HR-themed phishing.

BigBase (RU/KZ/BY/UA/US data)

A massive 700-million-record dataset dubbed BigBase, covering Russia, Kazakhstan, Belarus, Ukraine and the US, is circulating on BreachForums. Aggregated personal data at this scale fuels credential stuffing, identity fraud and targeted lookups against named individuals and companies.

Código fuente del troyano bancario BTMOB 3.6.3 a la venta

BTMOB (LATAM Android banking trojan)

Complete source code, reseller panel/server code and video tutorials for the BTMOB Android banking trojan are being shared, lowering the bar for new operators to build ATS/overlay campaigns. BTMOB is used against Latin American banks and their customers, so wider availability directly increases fraud risk for Argentine and regional financial institutions. Banks should update mobile-fraud detection for the 3.6.3 build and monitor for new reseller-distributed variants.

Ransomware group Emperador listed Brazilian firm GTL Concreto e Logística, which produces concrete and runs logistics and construction operations, claiming to have stolen financial documents, personal and customer data, and employee credentials. The Latin American victim spans manufacturing, finance and transportation, so the leaked data could fuel fraud and further intrusion.
