Romanian citizen Mircea-Ilie Ispasoiu made his first appearance in a New Jersey federal court after being extradited to the U.S. for allegedly orchestrating an international hacking scheme. 

The cyber attack targeted medical offices, retailers, security companies and United States residences, according to a Department of Justice release.  

Between 2011 and 2014, Ispasoiu worked as a computer systems administrator at a large Romanian financial institution. There he allegedly hacked into multiple private and business networks, including a company that ran background checks. He was able to access thousands of credit and debit card numbers and personal identifiers.

Ispasoiu is facing multiple charges of aggravated identity theft, unauthorized computer access to obtain information, unauthorized computer access that caused damage, and wire fraud. If convicted, he could face more than 30 years in prison and millions of dollars in fines.
