This coalition letter signed by a number of civil liberties organizations, privacy groups, and technology experts calls for the Senate to oppose the proposed amendment (No. 2626) from Sen. Whitehouse to the Cybersecurity Information Sharing Act (CISA), which would expand the Computer Fraud and Abuse Act (CFAA) in dangerous and unpredictable ways. The amendment would exacerbate existing problems with the CFAA and enable prosecution of behaviors that are not malicious computer trespasses or hacking, which was the original and appropriate target of the CFAA. Worse, these changes are being rushed through Congress without adequate debate over the far-reaching effects of its provisions.
