Original Post: Frida-JIT-unPacker: An Imperva Contribution to the Security Research Community, Presented at Black Hat Asia 2024
In the dynamic field of cybersecurity, combating malicious bots remains a paramount challenge for web applications. These bots use sophisticated techniques to bypass security measures, often protected by advanced source code obfuscation, preventing developers from crafting effective countermeasures.
Imperva Threat Research has developed a tool named Frida-JIT-unPacker to tackle this issue. This tool is designed to unpack and analyze .NET-protected malware, facilitating the understanding and mitigation of such threats. The tool, available on GitHub, benefits cybersecurity researchers by offering insights into the mechanics of various bot threats, such as credential stuffing, scalping, and scraping.
The document elaborates on the development process of Frida-JIT-unPacker, including technical details on .NET sample structures and reverse engineering methods. The tool uses Frida, a dynamic instrumentation toolkit, to intercept crucial API communications within the Common Language Runtime (CLR), retrieving clear data processed by the CLR engine.
By sharing this tool, Imperva aims to support the security research community in dissecting and counteracting sophisticated malware threats. The innovation has been featured at BlackHat Asia 2024, underlining its importance to the cybersecurity sector. Imperva continues to enhance its Advanced Bot Protection to defend against automated threats without compromising user experience.
Imperva offers a 30-day free trial to experience its comprehensive security solutions for web, mobile, and API endpoints.
