Last week, U.S. investigators uncovered a global financial network run by a senior Islamic State group official who was funneling money to an alleged ISIS operative in the U.S. through one of America’s favorite online platforms. The agent, disguising himself as a printer salesman, was receiving funds from the terrorist organization through fake eBay Inc. (EBAY) transactions, according to a recently unsealed FBI affidavit.

Mohamed Elshinawy, an American citizen, received a total of $8,700 from individuals working with the self-proclaimed Islamic State in order to aid in domestic attacks. Elshinawy, a man in his early 30s, was arrested in Maryland more than a year ago after an FBI surveillance operation found initial clues that he was linked to the terrorist group. He was later found to be part of a global network stretching from Britain to Bangladesh, built to fund a now-deceased senior ISIS official.

The eBay cash went for expenses such as a laptop, a mobile phone and software to set up a virtual private network that the FBI suspects was used in order to hide Elshinawy's internet usage as he communicated with ISIS operatives overseas.

Fintech Boom Complicates Terror Tracking

A spokesman for San Jose, Calif.-based eBay said the company “has zero tolerance for criminal activities taking place on our marketplace,” indicating that the e-commerce industry pioneer is swiftly working with law enforcement on the case. Elshinawy was reportedly not on eBay’s watch list and therefore his sale of two printers on the site did not spur an investigation into suspicious activity. The online marketplace says it has a “robust system in place to identify and prevent” such activity.

The incident brings to light the complexity in tracking the finances of global terror networks as they seek channels outside of traditional banks and find a plethora of options in the booming financial technology space. In the past, ISIS has gotten away with funding itself through means such as low-level fraud including check scams and online lending, as well as social media, prepaid cards and crowdfunding sites.
