New technology makes it easier to follow a criminal’s digital footprint

WEST LAFAYETTE, Ind. – Cybercriminals can run, but they cannot hide from their digital fingerprints.

Still, cybercrimes reached a six-year high in 2017, when more than 300,000 people in the United States fell victim to such crimes. Losses topped $1.2 billion.

Now, Purdue University cybersecurity experts have come up with an all-in-one toolkit to help detectives solve these crimes. Purdue has a reputation in this area – it is ranked among the top institutions for cybersecurity.

“The current network forensic investigative tools have limited capabilities – they cannot communicate with each other and their cost can be immense,” said Kathryn Seigfried-Spellar, an assistant professor of computer and information technology in the Purdue Polytechnic Institute, who helps lead the research team. “This toolkit has everything criminal investigators will need to complete their work without having to rely on different network forensic tools.”

The toolkit was presented in December 2018 during the IEEE International Conference on Big Data.

The Purdue team developed its Toolkit for Selective Analysis and Reconstruction of Files (FileTSAR) by collaborating with law enforcement agencies from around the country, including the High Tech Crime Unit of Tippecanoe County, Indiana. The HTCU is housed in Purdue’s Discovery Park.

FileTSAR is available free to law enforcement

FileTSAR is available free to law enforcement. The project was funded by the National Institute of Justice.

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.

“Our new toolkit allows investigators to retrieve network traffic, maintain its integrity throughout the investigation, and store the evidence for future use,” said Seunghee Lee, a graduate research assistant who has worked on the project from the beginning. “We have online videos available so law enforcement agents can learn the system remotely.”

FileTSAR captures data flows and provides a mechanism to selectively reconstruct multiple data types, including documents, images, email and VoIP sessions for large-scale computer networks. 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 or using their computers for workplace harassment.

“We aimed to create a tool that addressed the challenges faced by digital forensic examiners when investigating cases involving large-scale computer networks,” Seigfried-Spellar said.

The toolkit also uses hashing for each carved file to maintain the forensic integrity of the evidence, which helps it to hold up in court.

Their work aligns with Purdue's Giant Leaps celebration, celebrating the global advancements in artificial intelligence as part of Purdue’s 150th anniversary. This is one of the four themes of the yearlong celebration’s Ideas Festival, designed to showcase Purdue as an intellectual center solving real-world issues.

If you didn’t make it to Seoul for this year’s Uncovering Asia conference — or just couldn’t beat two panels at the same time — never fear, tipsheets from the impressive speakers are here! But just in case you can’t decide where to start, here are five presentations that are definitely worth checking out.

How to Make a Great Investigative Podcast

The human voice is a powerful tool. When someone is telling you a good story, you just can’t stop listening. It is, however, sometimes difficult to construct a good storyline for radio — especially if that’s new territory for you. In this excellent tipsheet, radio veteran Sandra Bartlett and Citra Prastuti, chief editor of Indonesian radio network Kantor Berita Radio, explain how to create images in your listener’s brain. Be sure to check out this story on some of their favorite investigative podcasts.

Best Verification Tools

From Russian trolls to teenage boys in MacedoniaCraig Silverman has exposed a wide gamut of disinformation operations around the world. He shared his experiences and research tips on a panel on fake news. Although years of experience like Silverman’s is certainly helpful, you don’t have to be an expert to spot fake news — or even a tech geek. In his tip sheet, Silverman continuously compiles tools that will help you to easily check out the accuracy of your sources.

Mojo in a Nutshell

Never heard of SCRAP or DCL? Then you are no different to most of the participants at the mojo workshop of award-winning television reporter Ivo Burum. Mojo is short for mobile journalism, which is becoming increasingly important in competitive, fast-moving newsrooms. Burum breaks down how to shoot, edit and publish an extraordinary video story just using your smartphone. Be sure not to miss his YouTube videos on mastering KineMaster or iMovie Basics or any of his regular columns on GIJN.

How to Track Criminal Networks

Transnational organized crime today generates $2 trillion in annual revenue, about the size of the UK economy, according to the UN Office on Drugs and Crime. It’s no wonder that, with that kind of cash on hand, authorities throughout the world often seem powerless to police them. But almost everybody leaves a digital trail, according to international affairs and crime reporter Alia Allana, who spoke at the Investigating Criminal Networks panel.

Web Scraping for Non-coders

Ever had a PDF document that you could not crawl with Ctrl + F? Or looked for specific information on a web page that has an endless number of pages? When documents have hundreds of pages or websites scroll for miles, it can be frustrating — not to mention time-consuming. With Pinar Dag and Kuang Keng Kueg Ser‘s guidance, you’ll be web scraping like a pro in no time.
