Product: BShield — Runtime Application Self-Protection (RASP)
Introduction
BShield is a "Made in Vietnam" Runtime Application Self-Protection (RASP) security solution that specializes in protecting mobile applications and games (Android, iOS) from real-time attacks.
BShield is integrated directly into applications to automatically detect and block reverse engineering, hooking, and fraud behaviors. Joining BShield, you will directly participate in a battle of wits against the latest attack techniques on the market.
WHAT WILL YOU DO?
Develop Core Shield (R&D)
- •Build protection layers: Design and develop anti-Debug, anti-Hooking, anti-Root/Jailbreak modules, emulator detection, and prevent all unauthorized interference with app Runtime.
Code Obfuscation
- •Implement code obfuscation techniques at LLVM IR, Bytecode, or Machine code levels to maximize the difficulty of reverse engineering.
Security Research
- •Analyze tools such as Frida, Magisk, APatch... and the latest attack techniques to continuously upgrade BShield's defensive capabilities.
Performance Optimization
- •Ensure the protection layer operates optimally – absolute security without slowing down the app, draining battery, or overheating the device for end users.
Partner with Customers (Support & Integration)
- •Integration support: Directly guide customer Dev teams to embed BShield into projects and configure on CI/CD systems.
- •Real-world troubleshooting: Analyze logs, identify root causes, and thoroughly resolve logic conflicts, crashes, or performance degradation issues.
