Context
BREEZE COMET is a financially motivated threat actor targeting Brazilian financial services, retail, and eCommerce organizations through compromised websites, custom malware, and stolen credentials to manipulate payment systems and execute fraudulent transfers.

Forensic evidence indicates that BREEZE COMET has executed waves of fraudulent transactions within 24-48 hours of compromise, likely stealing tens of thousands of USD in assets.
