QCSuper: Eavesdropping on Device Becomes a Hobby
QCSuper is a versatile tool that serves multiple purposes across different sectors. Its ability to capture and analyze raw radio frames from Qualcomm-based devices makes it indispensable for telecom operators, security researchers, network developers, and educators.
Main Features of QCSuper
📌Protocol Support: Captures raw radio frames for 2G (GSM), 2.5G (GPRS and EDGE), 3G (UMTS), and 4G (LTE) networks. Partial support for 5G is available for certain models
📌Device Compatibility: Works with Qualcomm-based phones and modems, including rooted Android devices and USB dongles
📌Data Output: Generates PCAP files with GSMTAP encapsulation, which can be analyzed using Wireshark
📌Ease of Use: Simple commands to start capturing data
📌Cross-Platform Support: Can be installed on both Linux and Windows systems, with detailed instructions provided for both platforms
📌Research and Analysis: Widely used by telecom, mobile, and security researchers for analyzing radio communication exchanges
Hardware Requirements for Using QCSuper
📌Qualcomm-Based Devices: The primary requirement is a Qualcomm-based phone or modem. This is because QCSuper relies on the Qualcomm Diag protocol to capture raw radio frames
📌Rooted Android Phone or USB Modem: For Android phones, the device must be rooted to access the necessary diagnostic interfaces
📌Operating System Compatibility: QCSuper has been tested on Ubuntu LTS 22.04 and Windows 11. It is recommended to use Linux for better compatibility
📌Wireshark: Wireshark is needed to analyze the PCAP files generated by QCSuper. Different versions of Wireshark are required depending on the type of frames being captured (e.g., Wireshark 2.x — 4.x for 2G/3G frames, Wireshark 2.5.x for 4G frames, and Wireshark 3.6.x for 5G frames)
Limitations
🚫QCSuper cannot be used with non-Qualcomm phones. The tool specifically relies on the Qualcomm Diag protocol to capture raw radio frames, which is a proprietary protocol available only on Qualcomm-based devices. Therefore, it is not compatible with phones or modems that do not use Qualcomm chipsets
🚫QCSuper cannot capture 5G radio frames on all devices. The ability to capture 5G frames is limited to certain models of Qualcomm-based devices. The tool has partial support for 5G, and this functionality has been tested under specific conditions with Wireshark 3.6.x. Therefore, not all Qualcomm-based devices will necessarily support 5G frame capture, and users may need to verify compatibility for their specific device model.
