.DESCRIPTION AutoSpamEmailScan.ps1 is used to monitor a specific mailbox that in enterprise users can forward suspicious spam emails to a specific mailbox.
    This PowerShell script can monitor the mailbox for any unread emails, grab the URLs and attachments from the emails and submit to virustotal.com, urlscan.io, Google safe browsing and OPSWAT. Script also can extract URLs from a pdf file.
    After the scan finished, script can generate HTML format scan report and auto reply to the senders.
    Script can be run once or loop interval, if in the init.conf is 0 means script will only run one time else the number is the loop interval seconds.
 
    Visit https://github.com/banhao/AutoSpamEmailScan to get the init.conf and Bytescout.PDF2HTML.dll, this dll file is used to convert PDF to HTML.
 
    Please check the License before you download this script, if you don't agree with the License please don't download and use this script. https://github.com/banhao/AutoSpamEmailScan/blob/master/LICENSE
 
    The Password is base64 encoded and saved in init.conf, following is the example about how to genertae the encoded password:
    "JkPgsiG9Zh0XCvk" is the password.
    "yp9P7" is the salt. make sure salt is the unique string that can't have the same pattern in the password.
    Insert the salt into password where ever you want:
    yp9P7JkPgsiG9Zh0XCvk, JkPgsiG9Zh0XCvkyp9P7, JkPgyp9P7siG9Zh0XCvk, JkPgsiG9Zh0XCyp9P7vk, ...... all these are legitimate.
     
    Generate the base64 encoded string:
    [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes("yp9P7JkPgsiG9Zh0XCvk"))
        eQBwADkAUAA3AEoAawBQAGcAcwBpAEcAOQBaAGgAMABYAEMAdgBrAA==
    [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes("JkPgsiG9Zh0XCvkyp9P7"))
        SgBrAFAAZwBzAGkARwA5AFoAaAAwAFgAQwB2AGsAeQBwADkAUAA3AA==
    [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes("JkPgyp9P7siG9Zh0XCvk"))
        SgBrAFAAZwB5AHAAOQBQADcAcwBpAEcAOQBaAGgAMABYAEMAdgBrAA==
    [Convert]::ToBase64String([System.Text.Encoding]::Unicode.GetBytes("JkPgsiG9Zh0XCyp9P7vk"))
        SgBrAFAAZwBzAGkARwA5AFoAaAAwAFgAQwB5AHAAOQBQADcAdgBrAA==
     
    Save the encoded string in the init.conf file.
     
    Decode the encoded string:
    [System.Text.Encoding]::Unicode.GetString([System.Convert]::FromBase64String("eQBwADkAUAA3AEoAawBQAGcAcwBpAEcAOQBaAGgAMABYAEMAdgBrAA=="))
        yp9P7JkPgsiG9Zh0XCvk
    [System.Text.Encoding]::Unicode.GetString([System.Convert]::FromBase64String("SgBrAFAAZwBzAGkARwA5AFoAaAAwAFgAQwB2AGsAeQBwADkAUAA3AA=="))
        JkPgsiG9Zh0XCvkyp9P7
    [System.Text.Encoding]::Unicode.GetString([System.Convert]::FromBase64String("SgBrAFAAZwB5AHAAOQBQADcAcwBpAEcAOQBaAGgAMABYAEMAdgBrAA=="))
        JkPgyp9P7siG9Zh0XCvk
    [System.Text.Encoding]::Unicode.GetString([System.Convert]::FromBase64String("SgBrAFAAZwBzAGkARwA5AFoAaAAwAFgAQwB5AHAAOQBQADcAdgBrAA=="))
        JkPgsiG9Zh0XCyp9P7vk
     
    Even someone can get the encoded string from the init.conf and use base64 to decode it, but they don't know the salt, so they still can't get the password directly.
 
    This PowerShell passed the test in PowerShell version 5.1.16299.1146. Can not run on Powershell version 4 and below.
    PS H:\>host
    Check the PowerShell version.
