Threat Risk: Medium
Victim: Banking customers in Mexico and Latin America
Incident: Resurgence of the Grandoreiro banking Trojan campaign using updated evasion tactics.
Impact: Financial loss and credential theft through keystroke logging and remote device control.
Attacker: Brazilian-based threat actors operating as a Malware-as-a-Service (MaaS)
Analysis: The Grandoreiro banking Trojan has resurfaced using DLL sideloading and legitimate applications to evade detection. Operators are now employing protected loaders to separate initial access from long-term capabilities, indicating a strategic shift toward higher stealth. While overall volume has decreased, the malware’s ability to adapt its infrastructure shows persistent intent.
Recommendations: Deploy endpoint detection and response (EDR) tools to monitor for suspicious DLL sideloading.; Restrict the installation of unauthorized third-party file-management software on sensitive systems.; Enforce hardware-based multi-factor authentication to neutralize the impact of stolen banking credentials.
