Duties of care and diligence against cybercrime

The present report is an exploratory investigation of whether contributory parties other than criminals and private individuals may have legal duties to help combat cybercrime. The scope is limited to four jurisdictions (The Netherlands, U.S.A., Brazil, and Czech Republic) and three specific topics of cybercrime: security of hardware and software, ransomware, and DDoS attacks. The focus is on a legal analysis, preceded by a brief factual description, and closing with tentative suggestions for improvement.
