Weaponizing LSPosed: Remote SMS Injection and Identity Spoofing in Modern Payment Ecosystems

This report analyzes an active financial-fraud campaign that uses an LSPosed Android module called "Digital Lutera" to hook system SMS and telephony APIs, exfiltrate registration tokens to Telegram, inject forged SMS entries, and remotely orchestrate UPI account takeovers via a Socket.IO C2; it includes code-level analysis, IoCs (telegram handle, C2 URL, package and file paths), actor attribution to "Berlin"/@Syntext_Erorr, observed operational activity, and recommended mitigations such as Play Integrity MEETS_STRONG_INTEGRITY, carrier-side validation, and runtime hook detection.
