Banking Trojan Targets Latin American Financial Users Through Social Engineering

JanelaRAT demonstrates how banking trojans continue to evolve with sophisticated techniques like DLL sideloading and real-time browser interception to steal financial credentials. The malware's success relies heavily on social engineering to trick users into executing malicious MSI files, bypassing traditional security measures through legitimate-looking installation processes. This threat particularly targets cryptocurrency and banking data, showing how cybercriminals adapt their tools to exploit regional financial behaviors and less mature security infrastructures in Latin America.
