OLR Report 2012-R-0254 explains the penalties under state law for computer hacking (accessing someone's computer without authorization).
Someone who hacks into another person's computer could be punished by a number of different crimes, depending on the circumstances. The law punishes hacking under the computer crime statutes. These crimes carry penalties ranging from a class B misdemeanor (punishable by up to six months in prison, a fine of up to $1,000, or both) to a class B felony (punishable by up to 20 years in prison, a fine of up to $15,000, or both). The law also punishes unauthorized access to a computer or computer network, with penalties ranging from a class B misdemeanor to a class D felony (punishable by up to five years in prison, a fine of up to $5,000, or both).
A number of generally applicable crimes could also apply. For example, hacking could be done to commit identity theft or larceny and it could be punished under those generally applicable crimes.
In addition to criminal penalties, the law specifically authorizes someone harmed by a computer or unauthorized use crime to bring a civil lawsuit against the perpetrator. These civil actions are in addition to any other grounds for a civil action that the injured party may have.
