IL HB2053

Amends the Criminal Code of 1961 to add "electronic hi-jacking" definition as a network security attack where an attacker takes unauthorized control of electronic communications, social networking sites, computer networks or programs.

Expands computer tampering offense to include electronically hi-jacking computers, computer networks, electronic mail, or social networking websites, and adds new offense of transmitting false data (such as information, pictures, or videos) while posing as the account or equipment owner.

Classifies transmitting false data while impersonating an account owner as a Class 4 felony (Class 3 felony for second or subsequent offense), same penalty as existing computer tampering offenses involving data damage or insertion of malicious programs.

Clarifies that accessing a computer network is authorized if the owner permits patrons, customers, guests, or the public to access it and the person complies with all stated terms and conditions for use.
