Computer Forensics Uncovers Evidence Tampering in Sledgehammer and Ergenekon Cases

What are Sledgehammer and Ergenekon?

Sledgehammer and Ergenekon are high-profile and ongoing political trials in Turkey.  Sledgehammer involves an alleged Turkish military coup and some of the most sophisticated digital forgeries Arsenal has ever seen.  Ergenekon involves an alleged "deep state" in Turkey with ties to the military, academia, NGOs, and media.  Forged documents critical to these cases include plans to bomb mosques, shoot down a fighter jet, and overthrow the Turkish government.

Why attend this presentation?

The Sledgehammer and Ergenekon cases have received significant press in the Middle East, but are only now receiving serious attention in the United States.  A recent New York Times front-page article on February 27 covered these cases, referring to document forgeries identified by Arsenal with digital forensics.  Attendees will be intrigued by details about Arsenal's work found exclusively in this presentation.

What people are saying.

"Mark Spencer's Sledgehammer presentation allows you to see evil up close and personal.  He tells an entertaining story and should turn his team's work into a book!" -- W. Olin Sibert, President, Oxford Systems, Inc.

"The Sledgehammer presentation is brilliant.  The reality is that motivated and technically competent adversaries can, by tampering with evidence, affect the power structures of nations." -- Paul Bowen, Director Emeritus, National Information Security Group, Inc.

"This presentation gives you a front-row seat to evidence tampering on an unprecedented scale.  Arsenal's dedication to digital forensics is obvious." -- Joseph Dahlbeck, Sergeant Detective, Boston Police Department

    Fantastic presentation!

    I should have announced the following position we have open at our firm during the jobs portion at the beginning, but I didn't and so here it is...

    We're looking for someone to join our IT Audit team. We do consulting with various clients, and the current role we're looking to fill is in IT compliance for a bank with an office in Quincy. You can learn more at and if you're interested, please email me ([masked]) your resume.

    Just think, if you come work for us, you too could have a email address!

    Mark Spencer, once again delivers a very compelling talk, has the makings of a spy novel infused with forensics. Also enjoyed Dawn's talk on S.E. Toolkit & how it can be used to spoof F.B., Missed Lucy & wish her the very best. Note: SOURCE Boston will be at the Marriot Tremont, next week Tue through Thurs.
    Great job Boston Security Meetup!

    I had a great time last night, thank you all for attending! If you haven't already, please email me ([masked]) and let me know what you thought. I have another topic in mind for a future Meetup that I think will raise the bar even further.

    I just finished my master degree in IT. This will be my first meet up. Thank you for this great opportunity.

    April 3, 2014

  • Mark S.

    Since this has been coming up privately and now here on the Meetup page, this presentation is something you need to see in person. Tomorrow night will be the second and probably last public Sledgehammer presentation in Boston.

  • Joe P.

    Will the slides and or presentation material be available to those who cannot make it?

    April 2, 2014

  • Mark S.

    Hi Chris, we'll discuss recording tomorrow night before I get started.

    1 · April 2, 2014

  • Chris S.

    Would it be alright to record this event (audio/video)? I have some stateside Turkish friends who don't live in Massachusetts but would be very interested in the content of this talk.

  • Cristian M.

    This will be my first Meetup, I'm excited about it. I love IT Security, thanks for this opportunity.
