FamousSparrow Deploys New SparroWocky Backdoor Against Latin American Governments

China-aligned APT FamousSparrow deployed a new modular backdoor, SparroWocky, against government entities across eight Latin American countries since August 2025, ESET reports.

ESET reports that China-aligned threat actor FamousSparrow replaced its SparrowDoor implant with SparroWocky, a distinct modular C++ backdoor active against governments in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico, and Venezuela. Around 90% of the group's targets from mid-2025 into 2026 were in Latin America, which ESET links to regional competition over US influence. The backdoor arrives via a three-component DLL side-loading chain, persists through a Windows service (ProcAuditManager) or Run keys (SnapCart), captures screenshots, and exfiltrates RC4-encrypted data over TLS C2 on ports 443 and 8080. It supports in-memory Beacon Object File execution, API hashing, and SilentMoonwalk-style call-stack spoofing; IOCs for three C2 servers were released.

RatHat Abuses Android Wireless Debugging to Gain Shell Access and Steal Banking PINs

New Android banking trojan RatHat abuses Wireless Debugging to gain shell access and steals banking PINs and OTPs via raw touch capture.

Zimperium and zLabs analyzed RatHat, an Android banking malware linked to China-based actors that chains Accessibility abuse and Wireless Debugging to obtain a local ADB shell without a host computer. Masqueraded Go binaries in /data/local/tmp provide persistence and an FRP reverse tunnel, while a getevent-based collector maps touch coordinates to PIN pads and pattern locks using locateValues.json layouts. It targets banking, crypto, WeChat and Alipay apps through smishing, malicious ads, and HTML overlays, and serializes the accessibility tree for a generative AI assistant to automate on-screen actions. Layered anti-analysis includes malformed DEX, a padded manifest, and debugger, Frida, and emulator checks.
