VirusTotal API 2.0 UDF

Danyfirex · May 13, 2013

Hi mates, well this is my first contribution. a simple UDF to use Virustotal API v2.0 The response return is not parsed|splitted. requires >WinHttp UDF

Functions List:

Update:

Now a Only Function using a flags for respective mode.

VT() Use respective flag($Type)

VT(ByRef $aAPI, $Type, $sResource, $sAPIkey,$Comments="")

flags($Type)

$fReport = retrieve a scan report on a given file

$fScan = submit a file for Scanning

$fRescan = Rescan files in VirusTotal's file store

$uReport = retrieve a scan report on a given URL

$uScan = submit a URL for Scanning

$Comment = Make a commnet on files and URLs

Example:

#include <Crypt.au3>
#include "VT.au3"

Example()

Func Example()

    _Crypt_Startup()
    Local $sFilePath = @WindowsDir & "\Explorer.exe" 

    Local $bHash = _Crypt_HashFile($sFilePath, $CALG_MD5)
   _Crypt_Shutdown()
    Local $hVirusTotal = VT_Open()
    Local $APIkey='Your API key'
    ConsoleWrite(VT($hVirusTotal, $fReport, '20c83c1c5d1289f177bc222d248dab261a62529b19352d7c0f965039168c0654',$APIkey) & @CRLF)
    ConsoleWrite(VT($hVirusTotal, $fScan, $sFilePath,$APIkey) & @CRLF)
    ConsoleWrite(VT($hVirusTotal, $fRescan, hex($bHash),$APIkey) & @CRLF)
    ConsoleWrite(VT($hVirusTotal, $uReport, "http://www.virustotal.com",$APIkey) & @CRLF)
    ConsoleWrite(VT($hVirusTotal, $uScan, "http://www.google.com",$APIkey) & @CRLF)
    ConsoleWrite(VT($hVirusTotal, $Comment, hex($bHash) ,$APIkey,"Hello Word | Hola Mundo") & @CRLF)
    VT_Close($hVirusTotal) ;
EndFunc   ;==>Example

Nice idea!

guinness · May 13, 2013

A nice idea and UDF. May I provide some suggestions?

; Firstly, Global variables should be at the top a script and not in a function.
; Secondly, how about removing Global variables and doing something like this?

Global Const $__sVirusTotal_Page = 'www.virustotal.com'

Func Example()
    Local $hVirusTotal = VT_Open() ; Pass the 'handle' to the appropriate functions.
    ConsoleWrite(VT_Url_Scan($hVirusTotal, 'someurl.com', 'API') & @CRLF)
    VT_Close($hVirusTotal) ; Pass the 'handle' from $hVirusTotal.
EndFunc   ;==>Example

Func VT_Open() ; Pass
    Local Enum $eAPI_HttpOpen, $eAPI_HttpConnect ; These could be in the Global space too.
    Local $aAPI[2] = [0, 0]
    $aAPI[$eAPI_HttpOpen] = _WinHttpOpen()
    If @error Then $aAPI[$eAPI_HttpOpen] = -1
    $aAPI[$eAPI_HttpConnect] = _WinHttpConnect($aAPI[$eAPI_HttpOpen], $__sVirusTotal_Page)
    If @error Then $aAPI[$eAPI_HttpConnect] = -1
    Return $aAPI
EndFunc   ;==>VT_Open

Func VT_Close(ByRef Const $aAPI)
    Local Enum $eAPI_HttpOpen, $eAPI_HttpConnect ; These could be in the Global space too.
    _WinHttpCloseHandle($aAPI[$eAPI_HttpOpen])
    _WinHttpCloseHandle($aAPI[$eAPI_HttpConnect])
    Return True
EndFunc   ;==>VT_Close

Func VT_Url_Scan(ByRef $aAPI, $sURL, $sAPIkey)
    Local Enum $eAPI_HttpOpen, $eAPI_HttpConnect ; These could be in the Global space too.
    If $aAPI[$eAPI_HttpConnect] = -1 Then $aAPI = VT_Open() ; Check if HttpConnect isn't -1, if it is then connect to VirusTotal.
    Return _WinHttpSimpleRequest($aAPI[$eAPI_HttpConnect], 'POST', '/vtapi/v2/url/scan', Default, 'url=' & $sURL & '&key=' & $sAPIkey)
EndFunc   ;==>VT_Url_Scan

Nice start!

Do you have any plans to marry it up to one of the JSON UDFs to extract the info?

Have fun!

John Morrison

Danyfirex · May 13, 2013

Thanks mates.

A nice idea and UDF. May I provide some suggestions?
...

Thanks for your suggestions I'will update it. maybe use JSON UDF to Get response returns Error too.

I thought some like this for Http

If @Error Return SetError(@Error,0,0)

or

Simple return @error

obvious I need split the response to manage page returns.

Hello,

thanks, very useful, How can I connect through a proxy?

Danyfirex · May 13, 2013

Hello,

thanks, very useful, How can I connect through a proxy?

change _WinHttpOpen parameters.

_WinHttpOpen([$sUserAgent = Default [, $iAccessType = Default [, $sProxyName = Default [, $sProxyBypass = Default [, $iFlag = Default ]]]]])

guinness · June 4, 2013

Awesome, you went with my design. Thanks for that.

storme · June 18, 2013

I had a bit of a play with the UDF and I don't appear to be getting anything back from "$fScan" and subsequent checks indicate that the file wasn't uploaded.

My Code (well actually just your example modified).

Local $hVirusTotal = VT_Open()
    ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ConsoleWrite(":" & VT($hVirusTotal, $fScan, $sFileName,$sVirusTotalAPIkey) & ":" & @CRLF)
    ConsoleWrite("@error = " & @error & @cr)
    ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ;ConsoleWrite(VT($hVirusTotal, $fRescan, hex($bHash),$sVirusTotalAPIkey) & @CRLF)
    ;1 = queued for rescanning. -1 = not present. 0 = unexpected error
    ;ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ConsoleWrite(VT($hVirusTotal, $fReport, hex($bHash),$sVirusTotalAPIkey) & @CRLF)
    ;
    ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    VT_Close($hVirusTotal) ;

The result

----------------------------------------------------------------------------------
::
@error = 0
----------------------------------------------------------------------------------
{"response_code": 0, "resource": "46B3CC00ECD3D3E042DECA0072B063B3", "verbose_msg": "The requested resource is not among the finished, queued or pending scans"}
----------------------------------------------------------------------------------

The file exists...... Any ideas what's going on?

Thanks!

guinness · June 18, 2013

storme,

Probably best to actually post what data the other variables contain instead of second guessing. Thanks.

storme,

No Guessing necessary.

The code is basically a cut and paste from the example in the OP.

This is the important line

VT($hVirusTotal, $fScan, $sFileName,$sVirusTotalAPIkey)

$hVirusTotal is set in the line above

$fscan is a UDF constant

$sFileName is the full path of the file (useless to anyone else, I stated it exists...and I checked with fileexists() to make sure it was ok)

$sVirusTotalAPIkey is my Virus total API key (Private not to be published)

The API states there should be a return from the file scan ($fScan) but as you see from the results it returns nothing.

Danyfirex · June 19, 2013

@storme I think the problem is that you'r not waiting the file scan and you trying to get the report.

When you upload some file for scanning you should wait some time to get the report file.

So

if I get this "The requested resource is not among the finished, queued or pending scans" So I should wait. I'll try some minutes later.

@storme I think the problem is that you'r not waiting the file scan and you trying to get the report.

When you upload some file for scanning you should wait some time to get the report file.

Yep understand that, the script I'm writing will do that when I can get it to submit a file to be scanned.

However, I'm not getting anything back from the submit to indicate it's done anything. According to the API help page there should be a report sent back with various information that I'll then use to keep track of files submitted.

if I get this "The requested resource is not among the finished, queued or pending scans"

So I should wait. I'll try some minutes later.

The message you quoted above states "or pending scans" so shouldn't my "pending scan" be in the list?

I submitted the file last night and it still isn't in the list. If it was submitted it should be there by now.

It appears as if the file isn't being submitted.

Have you tried your URL on a brand new EXE file that hasn't been submitted before?

BTW everything else works fine, if I use a file/hash that is already scanned.

So back to you...

John

Danyfirex · June 19, 2013

@storme have you tried with another file?

For me work correctly I just upload another file right now this is the response that you should to get

:{"scan_id": "c38c7912767533053ef8f1c647b4fbf9f37f5ee305ead5b3049c4346b5c4419a-1371648640", "sha1": "01fc1499d986a1593f51a40d8f4294b5b69e83d9", "resource": "c38c7912767533053ef8f1c647b4fbf9f37f5ee305ead5b3049c4346b5c4419a", "response_code": 1, "sha256": "c38c7912767533053ef8f1c647b4fbf9f37f5ee305ead5b3049c4346b5c4419a", "permalink": "https://www.virustotal.com/file/c38c7912767533053ef8f1c647b4fbf9f37f5ee305ead5b3049c4346b5c4419a/analysis/1371648640/", "md5": "e0efdfe49b64cf7c2fc191c969d2d29d", "verbose_msg": "Scan request successfully queued, come back later for the report"}:

~~which is the size of your file?~~

I keep thinking the problem is that you're not waiting enough(some minutes maybe 3 or 5)

Also

You can use a Http debugger to see what's wrong.

The file I was trying to upload/scan was an AutoIt program and my antivirus was intercepting and blocking it.

So the file was not passed to VT thus no report from the "$fScan".

I finally got it to go by disabling the antivirus.

It maybe worth adding some checks to your code to see if the files exists and can be opened.

An antivirus will probably allow you to check it exists but not open it.

Don't have any time to do any major checking now, wish I had found this last night when I did have time.

It's 2am here and I have to sleep but I did a bit of checking and got some strange results.

Test Code - VirusSubmit.exe (331KB) is the program I'm working on and Bitdefender (my antivirus) doesn't like it and is blocking it.

$sFileName = "P:\Autoit\_Projects\_MyProjects\VirusSubmit\VirusSubmit.exe"

; submit to Virustotal
    _Crypt_Startup()
    Local $bHash = _Crypt_HashFile($sFileName, $CALG_MD5)
    _Crypt_Shutdown()

    ;Check if hash exists
        ; Doesn't exist
            ; Submit file

    ;Get report
        ; Not ready yet (come back later)


    ConsoleWrite("FileExists = " & FileExists($sFileName) & @cr)
    ConsoleWrite("$bHash = " & $bHash & @cr)
    local $stest =  __WinHttpFileContent("", "file", $sFileName,"--------Boundary")

    ConsoleWrite("$stest-LEN = " & StringLen($stest) & " @error = " & @error & @cr)
    ConsoleWrite("$stest = " & $stest& @cr)

    Local $hVirusTotal = VT_Open()
    ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ConsoleWrite(":" & VT($hVirusTotal, $fScan, $sFileName,$sVirusTotalAPIkey) & ":" & @CRLF)
    ConsoleWrite("@error = " & @error & @cr)
    ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ;ConsoleWrite(VT($hVirusTotal, $fRescan, hex($bHash),$sVirusTotalAPIkey) & @CRLF)
    ;1 = queued for rescanning. -1 = not present. 0 = unexpected error
    ;ConsoleWrite("----------------------------------------------------------------------------------" & @cr)
    ConsoleWrite(VT($hVirusTotal, $fReport, hex($bHash),$sVirusTotalAPIkey) & @CRLF)
    ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $bHash = ' & $bHash & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console

Now as you can see there is information in VT now as I disabled the antivirus so it would transmit earlier tonight....

However you can see there was no submit for this file

::
@error = 0

Not sure how much this is going to help. If you can think of any tests you want me to try let me know and I'll try them when I get home.

Onward and upward!

On a related note, does your script provide the ability to upload via HTTPS? The reason I ask is that some UTM firewalls may block the transmission of a virus. While some UTMs can interrogate SSL, most don't; so it would be good to have this capability if possible.

Great UDF.
