A 22-year-old Grand Haven man has pleaded guilty to conducting a criminal enterprise in connection with the theft and sale of account access to Meijer “mPerks” accounts.
As part of his guilty plea, Mui will forfeit his computer tower and roughly $630,000 in cryptocurrency.
Meijer’s mPerks program is used by customers to accrue store credit on their accounts when they make purchases at Meijer. The points can be used as cash value toward purchases.
Authorities said Mui stole mPerks login credentials and sold them online. People then fraudulently redeemed points from the stolen accounts. Investigators believe that Mui got the login credentials from separate data breaches, cross-referenced them with mPerks, and then sold the logins online. It is not believed that Meijer was directly breached.
Meijer has reinstated the full previous balance of accrued points to impacted customers, which reportedly cost the grocery chain more than $1,000,000.
Mui was originally charged in December 2023 with one count of conducting a criminal enterprise, one count of use of a computer to commit a crime, and seven counts of identity theft. He pleaded guilty to conducting a criminal enterprise Monday, July 15.
He will be sentenced Sept. 5.
