Kaspersky卡巴斯基：2025年上帝模式开启-研究人员在车辆的主单元上运行Doom在远程攻击其调制解调器之后报告（英文版）

The modem under investigation, like any modern modem, implements several protocol stacks: 2G, 3G, and LTE. Clearly, the more protocols a device supports, the more potential entry points (attack vectors) it has. Moreover, the lower in the OSI network model stack a vulnerability sits, the more severe the consequences of its exploitation can be. Therefore, we decided to analyze the data packet fragmentation mechanisms at the data link layer (RLC protocol). We focused on this protocol because it
