Updated some info for SET (Social Engineer Toolkit) PDF’s x AntiVirus & Scoring System

Virus Total Public API will make my live much easier . Look previous post about it http://spookerlabs.blogspot.com/2010/08/virus-total-public-api.html .

Some results really surprised me . Take a look and do your all conclusions .

Best AntiVirus to detect SET Malicious PDF (higher is better):

      7  "Sophos"
      7  "Microsoft"
      7  "GData"
      7  "F-Secure"
      7  "F-Prot"
      7  "ClamAV"
      7  "BitDefender"
      7  "Avast5"
      7  "Avast"
      6  "Sunbelt"
      6 "nProtect"
      6  "McAfee-GW-Edition"
      6  "eTrust-Vet"
      5  "Symantec"
      5  "PCTools"
      4  "eSafe"
      3  "NOD32"
      3  "Kaspersky"
      3  "Ikarus"
      3  "Emsisoft"
      3  "Antiy-AVL"
      2  "McAfee"
      1  "VBA32"
      1  "Panda"
      1  "AVG"
      1  "Authentium"
      1  "AntiVir"
      1  "AhnLab-V3"


Missed PDF detection for SET malicious PDF's (higher is worst) :

      7  "VirusBuster"
      7  "ViRobot"
      7  "TrendMicro-HouseCall"
      7  "TrendMicro"
      7  "TheHacker"
      7  "SUPERAntiSpyware"
      7  "Rising"
      7  "Prevx"
      7  "Norman"
      7  "Jiangmin"
      7  "Fortinet"
      7  "DrWeb"
      7  "Comodo"
      7  "CAT-QuickHeal"
      6  "VBA32"
      6  "Panda"
      6  "AVG"
      6  "Authentium"
      6  "AntiVir"
      6  "AhnLab-V3"
      5  "McAfee"
      4  "NOD32"
      4  "Kaspersky"
      4  "Ikarus"
      4  "Emsisoft"
      4  "Antiy-AVL"
      3  "eSafe"
      2  "Symantec"
      2  "PCTools"
      1  "Sunbelt"
      1 "nProtect"
      1  "McAfee-GW-Edition"
      1  "eTrust-Vet"

As we can see lot of AntiVirus missed all PDF from SET what is a big problem for companies . Some AntiVirus have some methods that VirusTotal doesn't emulate and possible those methods could detect them .

I'll do a big analysis against all my pdf's and share the results .

Happy Hacking!

Virus Total Public API

Today I started to play with Virus Total Public API http://www.virustotal.com/advanced.html

My initial idea was to send files using command line and get the results quickly so I don't need a web browser and spend time uploading the file .

I read their inital samples/docs and build a mix of codes using python (most retrieve from their samples) and perl (only language I can try somehting) . By now what I have :

$ perl vt-auto.pl /LABS/pdf-basics/samples/AdamSamples/15

Sending file /LABS/pdf-basics/samples/AdamSamples/15 to Virus Total ...
Response from VT with resource "86ee2f99a207d31ea2b69198dc2bf5e7c7946eeae7dacdd6032f2c050525bc07-1282091669"

Waiting 120 seconds to wait file /LABS/pdf-basics/samples/AdamSamples/15 be scanned ...

Sending request fo Virus Total about /LABS/pdf-basics/samples/AdamSamples/15 with resource "86ee2f99a207d31ea2b69198dc2bf5e7c7946eeae7dacdd6032f2c050525bc07-1282091669"

Report Results for /LABS/pdf-basics/samples/AdamSamples/15 :
"nProtect": "Trojan-Exploit/W32.Pidief.16718.AV"
 "CAT-QuickHeal": ""
 "McAfee": "Exploit-PDF.b.gen"
 "TheHacker": ""

 "AntiVir": "EXP/Pidief.JX"
 "TrendMicro": "TROJ_PIDIEF.ADY"
 "Emsisoft": "Exploit.Pidief!IK"
 "eTrust-Vet": "PDF/Pidief.IQ"
 "Authentium": "PDF/Obfusc.D!Camelot"
 "Jiangmin": ""

 "AhnLab-V3": "PDF/Shellcode"
 "VBA32": ""
 "Sunbelt": "Exploit.PDF-JS.Gen (v)"
 "PCTools": "Trojan.Pidief"
 "Rising": ""
 "Ikarus": "Exploit.Pidief"
 "Fortinet": ""
 "AVG": "Exploit"
 "Panda": ""
 "Avast5": "JS:Pdfka-PO"

Detection : (31/41)

I'll improve and fix the code so I can share because now it's impossible . That 120 seconds that I wait is just to make sure that the scan will finish before I try to retrive the results but sometimes depending on file size it'll probably fail .

Nice resource from VirusTotal Team , congratulations!

Happy Hacking!

We sent some papers to a couple of conferences to star to share those information . I’ll let you know if we get approve and where =) .

Let’s keep improving our research and sharing each time more and more information. In the future we’ll share all the information , scoring and parser .

RazorBack - New Sourcefire VRT Project

VRT guys just released at Defcon 18 version 0.1 for RazorBack . The project is REALLY interesting and it's targeting client-side attack mostly since that's currently where most attacks are .

What is RazorBack ?

Project Razorback™ is an undertaking by the Sourcefire VRT.
Razorback is a framework for an intelligence driven security solution. It consists of a Dispatcher at the core of the system, surrounded by Nuggets of varying types.

The project page could be found here : http://labs.snort.org/razorback/

There you will find the slides, papers,  0.1 files version. Besides that they created a new channel at irc.freenode.net #razorback .

I'll try to do lot of test in next week and post about those here .

For sure this project will grow a lot quickly and kickass in the future . Get involved . I'll for sure .

Happy Snorting!

Snort 2.9.0 Beta Available

Awesome new features coming with snort 2.9.0 . I'll do lot of tests after Blackhat/Defcon .


A beta version of Snort 2.9.0 is now available on snort.org, at
http://www.snort.org/snort-downloads/

Snort 2.9.0 introduces:

  * Feature rich IPS mode including improvements to Stream for
    inline deployments.  Additionally a common active response API is
    used for all packet responses, including those from Stream,
    Respond, or React.  A new response module, respond3, supports the
    syntax of both resp & resp2, including strafing for passive
    deployments.  When Snort is deployed inline, a new preprocessor
    has been added to handle packet normalization to allow Snort
    to interpret a packet the same way as the receiving host.

  * Use of a Data Acquisition API (DAQ) that supports many different
    packet access methods including libpcap, netfilterq, IPFW, and
    afpacket.  For libpcap, version 1.0 or higher is now required.
    The DAQ library can be updated independently from Snort and is
    a separate module that Snort links.  See README.daq for details
    on using Snort and the new DAQ.

  * Updates to HTTP Inspect to extract and log IP addresses from
    X-Forward-For and True-Client-IP header fields when Snort generates
    events on HTTP traffic.

  * A new rule option 'byte_extract' that allows extracted values to
    be used in subsequent rule options for isdataat, byte_test,
    byte_jump, and content distance/within/depth/offset.

  * Updates to SMTP preprocessor to support MIME attachment decoding
    across multiple packets.

  * Ability to "test" drop rules using Inline Test Mode.  Snort will
    indicate a packet would have been dropped in the unified2 or
    console event log if policy mode was set to inline.

  * Two new rule options to support base64 decoding of certain pieces
    of data and inspection of the base64 data via subsequent rule
    options.

  * Updates to the Snort packet decoders for IPv6 for improvements to
    anomaly detection.

  * Added a new pattern matcher that supports Intel's Quick Assist
    Technology for improved performance on supported hardware
    platforms.  Visit http://www.intel.com to find out more about
    Intel Quick Assist.  The following document describes Snort's
    integration with the Quick Assist Technology
http://download.intel.com/embedded/applications/networksecurity/324029.pdf

  * Reference applications for reading unified2 output that handle
    all unified2 record formats used by Snort.

Please see the Release Notes and ChangeLog for more details.

Please submit bugs, questions, and feedback to snort-beta@sourcefire.com.

Happy Snorting!
The Snort Release Team
