The Invisible Risk: The Data-sharing Activities of Data Brokers and Information Leakage

Data brokers are the major players in the market for collecting, selling and sharing user information. This paper considers data brokers’ data sharing activities as a co-opetition between data brokers and investigates how the information collecting and sharing activities may lead to information leakage on the dark web. We find that S&P 1,500 firms experience higher information leakage when sharing more customer information with data brokers through third-party cookies. Further, using all the registered data brokers and their competitors as the sample, we observe that registered data brokers are more susceptible to information leakage with data sharing activities than unregistered data brokers. Our study provides initial evidence on the consequences of data brokers’ data sharing activities

Classifying the contents of cybersecurity risk disclosure through textual analysis and factor analysis

Cybersecurity has garnered much attention due to the increasing frequency and cost of cybersecurity incidents and has become a significant concern for organizations and governments. Regulators such as the Securities and Exchange Commission (SEC) have also shown an interest in cybersecurity and the quality of cybersecurity risk disclosures. This paper examines the informativeness of cybersecurity risk disclosures when cybersecurity incidents or related internal control weaknesses are reported. In particular, we propose a quantitative methodology, which is a combination of textual analysis and factor analysis, for classifying cybersecurity risk disclosures into nine factors. Our results show different disclosing patterns among firms depending on whether they had cybersecurity incidents and internal control weaknesses. Further, our analysis indicates that firms disclose control-related factors to mediate the negative effect of disclosing vulnerability-related factors. This study provides various stakeholders, including investors, regulators, and researchers, with insight into the informativeness of cybersecurity risk disclosures
