标题： Enterprise Security Incident Analysis and Countermeasures Based on the T-Mobile Data Breach

摘要： 本文全面分析了T-Mobile在2021年和2023年的关键数据泄露事件，并对其系统、基础设施和公开暴露的端点进行了全方位的安全审计。 通过结合基于案例的漏洞评估与主动伦理黑客技术——包括Shodan侦察、API滥用模拟、VNC暴力破解、固件逆向工程和网络应用扫描——我们发现了在初始泄露事件之后仍然存在的结构性弱点。 在这些发现的基础上，我们提出了一种多层防御策略，包括零信任架构、细粒度基于角色的访问控制、网络分割、使用AES进行固件加密并带有完整性检查，以及API速率限制和令牌生命周期控制。 财务模型表明，五年的投资所带来的收益不到预期泄露损失的1.1%，验证了主动安全措施的成本效益。 我们的工作将事件后的事后分析与实际的安全评估相结合，为寻求运营弹性、合规性和跨领域威胁准备的大规模电信公司提供了可操作的蓝图。 显示英文摘要

摘要： This paper presents a comprehensive analysis of T-Mobile's critical data breaches in 2021 and 2023, alongside a full-spectrum security audit targeting its systems, infrastructure, and publicly exposed endpoints. By combining case-based vulnerability assessments with active ethical hacking techniques--including Shodan reconnaissance, API misuse simulations, VNC brute-forcing, firmware reverse engineering, and web application scans--we uncover structural weaknesses persisting beyond the initial breach events. Building on these findings, we propose a multi-layered defensive strategy encompassing Zero Trust Architecture, granular role-based access control, network segmentation, firmware encryption using AES with integrity checks, and API rate limiting and token lifecycle control. Financial modelling demonstrates that a five-year investment yields less than 1.1% of expected breach losses, validating the cost-effectiveness of proactive security measures. Our work bridges post-incident forensic analysis with hands-on security evaluation, providing an actionable blueprint for large-scale telecoms seeking operational resilience, regulatory compliance, and cross-domain threat readiness.
