WHOIS history on that domain shows the registration changed hands on November 15, 2016. Before that, it was owned by "Digital River, Inc.":

    Registrant Name: Digital River, Inc.
    Registrant Organization: Digital River, Inc.
    Registrant Street: 10380 Bren Road West
    Registrant City: Minnetonka
    Registrant State/Province: MN
    Registrant Postal Code: 55343
    Registrant Country: US
    Registrant Phone: [phone]
    Registrant Email: [e-mail]

Digital River appears to be an online commerce company: https://www.digitalriver.com/cloud-based-ecommerce-solutions...

They were probably the legitimate owners. The domain registration expiration date at that time was set for 2017, so it doesn't look like a registration lapse. It's unclear how and why the ownership was transferred.
