今天分享的PowerShell脚本，专治各种‘看不见’的恶意进程：
✅ 自动识别高危端口（135/445/139）关联进程
✅ 透视进程签名/路径异常（比如svchost.exe 躲在C:Temp）
✅ 生成HTML报告+高亮风险项
——让后门程序无所遁形！”
（以下为脚本核心代码预览，完整版见文末）
<#
.SYNOPSIS
生成带安全风险评估的网络端口通信报告（兼容所有PS版本）
.DESCRIPTION
功能清单：
1. 全端口扫描（TCP/UDP）
2. 标注危险等级（高/中/低）和入侵方法
3. 按风险等级排序输出
4. 自动生成可视化HTML报告

<h3>🔧 加固建议</h3>
<ol>
<li><strong>高危端口</strong>：立即关闭非必要的135/445端口，安装KB5034439补丁</li>
<li><strong>中危端口</strong>：配置防火墙规则限制访问源IP</li>
<li><strong>可疑进程</strong>：检查非系统目录进程的签名证书</li>
</ol>
