LLVM pass plugin for native code obfuscation — CFG flattening, string encryption, anti-debug, VM virtualization, and more. Supports iOS & Android.

Runtime memory toolkit for jailbroken iOS — scan, patch, freeze, and pointer scan with in-app overlay GUI.

Static analysis tool that visualizes iOS app exposure to reverse engineering.

ADB-based memory modification tool for rooted Android devices.

Web-based Android APK packer. Encrypts DEX bytecode, native libraries, and assets with AES-256-GCM. Supports Unity, multidex, and standard apps. No source changes required.

Frida-based Android Analyzer toolkit.

MITM HTTP/HTTPS proxy for inspecting and modifying traffic — GUI/CUI, rule engine, GraphQL support, security tools.

Async job queue for Python — Redis/PostgreSQL/MySQL backends, priority queues, job dependencies, dead letter queues, Prometheus metrics, built-in dashboard.

An open-source LLVM New Pass Manager obfuscation and anti-tamper toolkit for mobile game anti-cheat binaries on iOS and Android. Provides nine composable LLVM passes including control-flow flattening, bogus control flow, instruction substitution, string encryption, constant obfuscation, memory-value obfuscation, indirect branching, and basic-block splitting/reordering. Includes IL2CPP-aware string handling and dual-XOR tamper detection.

A framework for hiding anti-cheat detection logic via server-side fully homomorphic encryption (FHE). Clients encrypt game state under a public key; the server evaluates detection functions over ciphertexts, returning only a binary verdict. Proves logic secrecy and soundness under LWE, and proposes a randomized response mechanism against adaptive oracle queries.

Spectral feature extraction framework for Android malware detection. Extracts normalized power spectra from raw DEX bytecode and compresses them into compact feature vectors via polynomial approximation — robust against graph-preserving obfuscation.
