-一、源代码结构与功能
-APT-Hunter的源代码主要由Python编写，包含多个模块和脚本，用于实现日志收集、解析、分析以及结果输出等功能。
-
-日志收集：
-源代码中包含了用于收集Windows事件日志的PowerShell脚本（windows-log-collector-full-v3-CSV && windows-log-collector-full-v3-EVTX）脚本能够提取CSV和EVTX格式的日志。
-用户可以通过运行这些脚本来自动收集所需的日志，而无需手动查找和提取。
-日志解析：
-APT-Hunter使用内置库（如csv库）来解析CSV日志文件，使用外部库（如evtx库）来解析EVTX日志文件。
-解析过程中，APT-Hunter会使用正则表达式（Regex）为每个事件提取字段，以便后续分析。
-日志分析：
-源代码中包含了用于分析日志的逻辑，这些逻辑基于Mitre ATT&CK战术和技术，将攻击指标映射到Windows事件日志中。
-分析过程中，APT-Hunter会检测各种可疑活动，如恶意软件的安装、未授权的网络连接等，并生成相应的报告。
-结果输出：
-分析结果可以以Excel工作表和CSV文件的形式输出，便于用户查看和分析。
-其中，Excel工作表包含了从每个Windows日志中检测到的所有事件，而CSV文件则可以用于时间线分析。
-二、关键模块与代码分析
-日志收集模块：
-该模块主要包含PowerShell脚本，用于从Windows系统中提取日志。
-脚本中使用了Windows事件日志API或PowerShell命令来获取日志数据，并将其保存为CSV或EVTX格式。
-日志解析模块：
-该模块使用Python编写，包含了用于解析CSV和EVTX日志文件的函数。
-在解析CSV文件时，使用了Python的csv库来读取文件并提取字段。
-在解析EVTX文件时，使用了外部库（如pyevtx）来读取文件并解析事件。
-日志分析模块：
-该模块是APT-Hunter的核心部分，包含了用于检测可疑活动的逻辑。
-逻辑中定义了多个检测规则，这些规则基于Mitre ATT&CK战术和技术，用于识别各种APT攻击指标。
-分析过程中，APT-Hunter会遍历日志文件中的事件，并根据检测规则进行判断和分类。
-结果输出模块：
-该模块负责将分析结果输出为用户可读的格式。
-在输出Excel工作表时，使用了Python的pandas库来创建和填充工作表。
-在输出CSV文件时，则直接使用了Python的文件操作函数来写入数据。
-三、技术亮点与优势
-高效性：APT-Hunter能够快速地收集、解析和分析大量的Windows事件日志，提高了威胁检测的效率和准确性。
-易用性：该工具提供了友好的用户界面和简洁的操作流程，使得用户能够轻松上手并快速掌握其使用方法。
-兼容性：APT-Hunter支持多种格式的日志解析和输出配置，使得用户能够灵活地将其集成到现有的安全监控系统中。
-开源性：作为一款开源工具，APT-Hunter的源代码是公开的，用户可以根据需要进行二次开发或定制。
-四、结论与展望
-通过对APT-Hunter源代码的分析，可以看出该工具在Windows事件日志的威胁搜寻方面具有较高的效率和准确性。其友好的用户界面、简洁的操作流程以及灵活的日志解析和输出配置，使得用户能够轻松地使用该工具进行威胁检测和分析。然而，随着APT攻击的不断发展和变化，APT-Hunter也需要不断更新和完善其检测规则和功能，以应对新的威胁和挑战。未来，可以进一步优化APT-Hunter的性能和效率，提高其适用性和易用性，并探索与其他安全监控系统的集成和联动，以实现更加全面和高效的安全防护。
