Majerczyk is accused of orchestrating a phishing scheme that illegally accessed more than 300 email and other online accounts, including those belonging to actress Jennifer Lawrence.
Federal agents have said Lawrence broke down and became distraught during a 2014 meeting about nude photos of her that appeared online.
A Chicago man was sentenced on Tuesday to nine months in prison for hacking the electronic accounts of 30 celebrities and stealing private information, including nude videos and photos.
Majerczyk illegally accessed the accounts of those people who provided that information.
