astsu

astsu 工作原理 扫描常见端口 向目标发送一个 TCP Syn 包到指定端口，如果端口开放，则使用 nmap 扫描检查该端口上运行的服务，并打印所有发现的端口。 发现网络中的主机 以路由器的 IP 为基础，映射所有可能的 IP。然后向每个 IP 发送 ICMP 包，等待响应。如果收到任何响应，将在线主机的 IP 存储在一个数组中，当检查完所有主机后，打印所有在线主机。 操作系统扫描 向目标发送一个 ICMP 包并等待响应。然后，从目标响应中提取 TTL，并在列表中检查可能的操作系统，如果找到，则打印。 支持的操作系统 Windows ✔️ Linux ✔️ Mac ❓ 安装方法...
