Banana RAT Propose Change

Actor(s): SHADOW-WATER-063

According to Trend Micro, Banana RAT is a Brazilian banking trojan linked to SHADOW-WATER-063. It employs a fileless, PowerShell-based client that runs in memory, with a polymorphic, AES-wrapped payload delivery pipeline and multiple obfuscation layers to evade detection. Once active, it provides remote fraud capabilities, including screen capture, remote input control, keylogging, overlays that mimic banking interfaces, and a Pix QR interception subsystem to manipulate payments. The operation targets Brazilian financial institutions, uses Brazilian Portuguese artifacts, and appears to operate as a malware-as-a-service style platform with per-victim builds to complicate detection.
