Majerczyk's attorney, Thomas Needham, could not immediately be reached for comment.
Majerczyk, who resides in Chicago and Orland Park, Illinois, was originally charged in Los Angeles, but his case was transferred to Illinois as part of his plea agreement.
Majerczyk pleaded guilty in September to federal computer hacking charges but, the Justice Department and Mr Needham said investigators had not uncovered any evidence linking Majerczyk to the actual leaks.
Through this scheme, Majerczyk was able to access full iCloud backups belonging to numerous victims, including at least 30 celebrities, many of whom reside in the Los Angeles area, the plea agreement stated.
While no victims were named in court documents, the investigation began after Oscar winner Jennifer Lawrence and other celebrities, including actresses Kirsten Dunst and Gabrielle Union and model Kate Upton, complained in interviews about having their private photos end up publicly disseminated online.
