Purdue University Creates Cyber Toolkit

March 4, 2020 — Purdue University cybersecurity experts have developed technology that helps law enforcement track down cybercriminals by following their "digital footprint".

The Toolkit for Selective Analysis and Reconstruction of Files (FileTSAR) "allows forensic investigators to capture, selectively analyze and reconstruct files from network traffic,” said Kathryn Seigfried-Spellar, an associate professor of computer and information technology in the Purdue Polytechnic Institute, who helps lead the research team. “The main functions of this tool are capturing data flows and providing a mechanism to selectively reconstruct documents, images, email, and VoIP conversations.”

Seigfried-Spellar said the toolkit could be used to uncover any network traffic that may be relevant to a case, including employees who are sending out trade secrets.

The Purdue toolkit brings together in one complete package the top open-source investigative tools used by digital forensic law enforcement teams at the local, state, national and global levels.

More than 100 law enforcement agencies from across the world have requested access to the technology, which is being licensed through the Purdue Research Foundation Office of Technology Commercialization. You can learn more about it here.
