NY Penal Law § 156.10: Computer trespass

Unauthorized access of a computer can include a number of different activities including figuring out another person's password and using it to access that person's computer, giving a password to another person who does not have authorization to access the computer, hacking into someone's computer via the internet, or pretending to be another person in order to access computer services that would otherwise not be available to you. Such activities are crimes. There are several crimes in the New York criminal code related to unauthorized access of a computer. The specific charge that you will face largely depends on what you do or intend to do once you accessed the computer. Under New York Penal Law § 156.10 you have committed the computer trespass if you knowingly use or access a computer, computer service, or computer network without authorization, and you also

  1. Do so with the intent to commit a felony, or
  2. Knowingly gain access to computer material.

Louis Puesan was on disability leave from his job as a field technician with Time Warner Cable. While on leave he was no longer authorized to access the company's offices or computer system. However, Puesan did gain access to the company's offices and was observed using three different company computers. Company employees later discovered that someone had installed keystroke logging software on the three computers that Puesan was observed using. This software allowed Puesan to gain access to confidential customer information. Puesan was charged with computer trespass. People v. Puesan, 973 N.Y.S.2d 121 (N.Y. App. Div., 2013)

Related Offenses
  1. Unauthorized use of a computer: N.Y. Pen. Law § 156.05
  2. Criminal possession of computer related material: N.Y. Pen. Law § 156.35

In order to successfully prosecute you for a charge of criminal trespass the prosecutor must prove not only that you accessed a computer without authorization, but that you also did so in furtherance of a felony or that you actually gained access to material on the computer. If you simply accessed a computer but did nothing else, then a charge of computer trespass would not be appropriate.

In addition, the prosecutor must prove that you were the one who unlawfully accessed the computer. If someone other than you used your computer to commit a computer crime without your knowledge, then the prosecutor will have a difficult time prosecuting for computer trespass or any other computer crime.


As a Class E felony, if you are convicted of computer trespass your sentence may include a prison term of up to 4 years, a probation term of 5 years, and a fine.

Client Reviews
My wife and I met under some unconventional circumstances. After I had some legal problems, Mr Bilkis and his firm continually got me out of trouble. I then had his firm represented my wife and he got her out of trouble! We are still married and got our ways straightened away. We both can't thank him enough for saving our lives and our families! J.P.
I contacted Stephen Bilkis' office for an issue regarding a family member and I could not be happier with the results. I have recommended the firm to friends and family, all of whom were also ecstatic with Mr. Bilkis and all members of his staff. P.R.
I was in need of legal assistance for a very sensitive matter for a family member. I contacted the law offices of Stephen Bilkis & Associates, PLLC and was met with staff whose demeanor was supportive, compassionate and professional. The lawyer handling our case had many years of experience and treated us as if we were his own family. Our experience was so good, and we became so close to all of the staff and all of the attorneys who assisted us, that we consider them our extended family and continue to send them our home baked gifts for the holidays. P.A.K.
I hired Stephen Bilkis and Associates to represent me on a legal matter a few months ago and am grateful for their swift action and resolution on my behalf. I was impressed with their professionalism and would recommend them to friends and family in a heartbeat. M.B.
