What it detects

This rule detects a command shell started in a minimized window that echoes and opens a decoy NotaFiscal PDF which the CarnavalHeist banking trojan LNK uses to distract the victim while it stages its loader. Minimized window execution with an invoice-themed decoy is a social engineering and defense evasion pattern in Brazilian banking malware.
