In a filing with the court in November, Massachusetts U.S. Attorney Carmen Ortiz called Miller's actions "widespread, persistent and pernicious hacking" and said he was aware he was breaking the law, but she also said it's not clear how much actual damage he caused.
"Likewise, he did not successfully monetize his hacking activities," Ortiz wrote, adding that the government is only aware of a $500 sale completed before the undercover agent got in touch with Miller.
Ortiz recommended an 18-month sentence, three years of supervised release and monetary penalties of about $16,000 to U.S. District Judge Mark Wolf of the District of Massachusetts.
However, in letters to the court, Miller and members of his family, including his mother and father, pleaded for him to be spared jail time, saying he was very sorry for his actions, is seeing a psychiatrist for depression, and is needed at home to help care for his mother, who is very ill.
Miller faced a maximum penalty of 15 years in prison and $500,000 in fines for the three counts in his indictment that he pleaded guilty to. He had previously been convicted in 2004, when he was a minor, of being involved in writing malicious software, according to Ortiz's filing.
