"Criminal property destruction in Pennsylvania is charged as criminal mischief. Common circumstances of this charge are vandalism, or damage resulting from other personal or domestic disputes, revenge, road rage, or other reckless behavior that damages another person’s physical property." - Get Lawyer Leads, Inc.

Penalties and Sentences
"The computer crimes defined by Pennsylvania statutes generally lead to charges as third degree felonies. State law permits a term of imprisonment for up to seven years upon conviction for a third degree felony.
In addition to a term of imprisonment, the potential punishment for a computer crime in Pennsylvania may also include restitution payable to the victims. Upon conviction, the defendant may need to repay the victim for the cost of repairs, lost profits, and the cost of data restoration." - statelaws.findlaw.com
Hacking is highly discouraged. I recommend using the internet as a database for information or finding others with similar ideas and always navigating within the law.
