【摘要】：我们目前正处在“互联网2.0”时代,4G、5G是当前的主流,所以会感觉2G已经离我们很遥远了。其实并不然,我们目前在绝大多数的情况下,还会使用2G网络,这就涉及到了GSM网络。GSM网络不安全这件事早已经是国内外安全圈子所知晓的。这项技术在2010年时已经十分的成熟,而在2012年已经出现了比较完整的开源方案—osmocomBB项目。本文将介绍osmocomBB项目如何实现Gsm_sniffer,通过大量的实验,借助开源操作系统Kali Linux,将整个OsmocomBB嗅探平台部署在上面。使用这个平台将破解固件通过“软”刷机的方式写入到手机中去,然后抓取手机与基站进行数据交换的通信数据。整个平台由开源项目osmocomBB与物理硬件一台摩托罗拉C118手机组成。通过手机端RAW中的Layer1层与PC上位机中的layer2层和layer3层之间的相互协同工作,能够通过手机捕获到附近的RF信号。osmocomBB会选择附近的基站,截获基站与手机之间的通信数据,将数据发送到计算机中。在计算机中通过将数据进行封装并发送到指定的端口中。然后通过解码,还原了信息的内容。GSM网络已经无法保障人们的日程通信安全,所以我们将通过下面的实验来测试GSM的安全性,并做出相关的威胁评估,希望人们重视起通信安全。
[Abstract]:We are currently in the "Internet 2.0" era of 4GG 5G is the current mainstream, so will feel like 2G is far away from us. In fact, in most cases, we still use 2G network, which is related to the GSM network. The security of the network is already known at home and abroad. The technology matured in 2010, and in 2012 a more complete open source program-osmocomBB was launched. This article will introduce how to implement the osmocomBB project, through a large number of experiments, with the help of open source operating system Kali Linux, the entire OsmocomBB sniffing platform will be deployed on it. Use this platform to "soft" the firmware to write to the mobile phone through the "soft" way, and then grab the mobile phone and the base station for data exchange communication data. The whole platform is composed of open source project osmocomBB and physical hardware, a Motorola C 118 phone. Through the cooperative work between the Layer1 layer in the mobile phone RAW and the layer2 layer and the layer3 layer in the PC, it can capture the nearby RF signal. OsmocomBB will select the nearby base station through the mobile phone, and intercept the communication data between the base station and the mobile phone. Send data to your computer. In the computer by encapsulating the data and sending it to the specified port. Then, by decoding, restoring the content of the information. GSM network can no longer guarantee the security of people's daily communication, so we will test the security of GSM through the following experiments, and make the related threat assessment. It is hoped that people will attach importance to the security of communications.
