Final answer:
Using unauthorized passwords to access the CDC's database constitutes computer fraud or data theft, which is a violation of law, specifically the Computer Fraud and Abuse Act.
Step-by-step explanation:
If Gunther uses unauthorized passwords to access the data from the Center for Disease Control, regardless of his previous internship there, he is possibly committing a crime. This act falls under unauthorized access and could be classified as computer fraud or data theft. Accessing a secure database without proper authorization violates various federal and state laws, including the Computer Fraud and Abuse Act (CFAA) in the United States. If he includes this data in a marketing brochure, Gunther could face serious legal penalties, and his company could be subject to considerable liabilities, including violations of privacy laws and misuse of confidential health data.
