Two men have pleaded guilty for their roles in a computer hacking and spamming scheme that federal prosecutors in New Jersey say compromised the personal information of tens of millions of people.
Tomasz Chmielarz, of Rutherford, New Jersey, and Devin McArthur, of Ellicott City, Maryland, pleaded guilty to conspiracy charges Thursday.
Authorities say the men operated a business known as A Whole Lot of Nothing that sent spam emails on behalf of clients including insurance companies and online pharmacies.
Chmielarz admitted that he wrote computer programs to send spam in a way that bypasses email filters and also hacked into corporate email accounts to send spam.
They are scheduled to be sentenced Sept. 13, one month before co-defendant Timothy Livingston, of Boca Raton, Florida, is scheduled for trial.
