CertVerify 是一款旨在检测使用不受信任或已泄露的代码签名证书签名的可执行文件（exe、dll、sys）的工具。该工具的目的是识别那些使用已被泄露、被盗或来自不可信来源的证书签名的潜在恶意文件。
使用已被泄露或不受信任的代码签名证书签名的可执行文件可用于分发恶意软件和其他恶意程序。攻击者可以利用这些文件绕过安全控制，使其恶意软件对受害者看似合法。此工具有助于识别这些文件，以便进一步移除或调查。
作为之前恶意软件扫描器项目的延续，我创建了这样一个工具。在安全事件应急响应中，此类工具也至关重要。
CertVerify 无法保证所有被识别为可疑的文件一定都是恶意的。文件可能被误判为可疑，或者恶意文件可能被扫描器遗漏。
该扫描器仅针对已被公共社区识别为恶意的代码签名证书。这包括通过恶意软件分析工具和服务以及其他公共来源提取的证书。存在大量未被验证的恶意软件签名证书，无法获取所有恶意签名证书，该工具只能检测其中一部分。如需额外检测，您需要自行提取证书的序列号和指纹信息并添加到签名库中。
本工具的范围不包括针对已抢先在内核级别运行的特殊 rootkit（例如无文件启动套件或通过高级技术隐藏的隐藏文件）提取代码签名信息。换句话说，运行此工具时，它将在用户级别执行。内核级别的类似功能使用 antirootkit 或 EDR 更为准确。请牢记这一点，并重点关注其思路和原理……要实现适合本工具目的的原理，您需要开发一个驱动程序（.sys）并以 NT\SYSTEM 权限在内核中运行它。
尽管如此，如果您希望在 Windows 系统入侵事件中运行此工具，并且您的目标是 sys 文件，请在运行工具前以安全模式或其他不加载 Windows 系统额外驱动程序（仅加载默认系统驱动程序）的启动选项启动。我认为这样会更有帮助。
或者，将 Windows 系统磁盘挂载到 Linux 上，然后在 Linux 环境中运行该工具。我认为这可能会产生更好的结果。
