Banana RAT
Intelligence Profile
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.
Threat Analysis
Banana RAT is a advanced-sophistication threat actor of undetermined national origin, engaged in cyber operations with a primary motivation of espionage.
The group's espionage-oriented operations suggest a state-sponsored or state-aligned mandate, typically focused on stealing intellectual property, government secrets, or military intelligence. Targets are usually selected for strategic value rather than financial gain.
Classified as an advanced threat actor, Banana RAT likely develops or acquires zero-day exploits, employs custom malware toolchains, and demonstrates long-term persistence capabilities — hallmarks of a well-resourced operation consistent with nation-state backing.
