Arsenal Reveals Sophisticated Evidence Tampering Involving Turkish Journalists

Arsenal Consulting President Mark Spencer’s article in Digital Forensics Magazine (Issue 27, published May 1) describes how his firm uncovered evidence tampering which led to the wrongful imprisonment of Turkish investigative reporter Baris Pehlivan and his colleagues at Odatv. Odatv runs one of the most popular news websites in Turkey and has a reputation for being critical of the current government, controlled since 2002 by the Justice and Development Party. Mr. Pehlivan and his colleagues are currently on trial and accused of supporting the Ergenekon terrorist organization. Ergenekon is an alleged secularist “deep state” in Turkey with ties to the military, academia, NGOs, and the media whose supporters are charged with plotting to overthrow the government.“Arsenal has a great deal of experience identifying evidence tampering, but even we were surprised by the volume and nature of the attacks against Mr. Pehlivan’s Odatv computer,” Mr. Spencer said. “Unfortunately for Mr. Pehlivan and his colleagues, these attacks were ultimately successful and resulted in their imprisonment.”

Arsenal used an analysis technique known as “Anchors in Relative Time” to reveal critical details about the attacks – details other digital forensics experts missed. This analysis technique allows digital forensics experts to determine when, in relative time, important events have occurred within electronic evidence, even when all the dates and times associated with those events cannot be trusted. Anchors in Relative Time has become one of Arsenal’s most powerful weapons when confronting sophisticated evidence tampering.

Mr. Spencer will be discussing the analysis of Mr. Pehlivan’s Odatv computer at the Internet Security Operations and Intelligence conference in San Francisco, CA on May 12 and the High Technology Crime Investigation Association’s Mid-Atlantic Chapter meeting in Manassas, VA on May 19.
