golang获取windows版本和详细信息

场景:

将木马丢到感染机运行后回连时希望返回感染机的操作系统信息.golang 可以通过runtime.OS获取到操作系统类型,但是无法获取详细的版本信息,如win7 win10等,

解决方案;

下面是chatgpt的写法;

    "fmt"

        return
    }
 
    fmt.Println("Windows version:", version)
}

    kernel32, err := syscall.LoadDLL("kernel32.dll")
    if err != nil {
        return "", err
    }
 
    proc, err := kernel32.FindProc("GetVersion")
    if err != nil {
        return "", err
    }
