There's not enough detail in your question, and what information you have needs clarification. You should contact and engage an IP attorney, and provide specific details. Nonetheless, use of the copyright of a third party, even if credited, may be an infringement and/or criminal act unless the use falls within certain limited exceptions.

It depends on what the information is. If it is proprietary information protected by copyright than using it without the owner's permission would be copyright infringement. One thing to look for is whether there is a copyright notice on the work. A copyright notice is an clear indication that someone believes the work is their intellectual property and they are likely to have a copyright registration. You can search the Copyright Office to see if the owner [if you know their name] has a copyright registration issued on the work. If you want to protect yourself from a suit for copyright infringement, I recommend that you consult an intellectual property attorney for an opinion.
