Drug transactions and the dark web: Public perceptions of the locational setting of offenders and support for drug policy outcomes.

Background: Both legal and extra-legal factors influence judicial and non-judicial opinions about persons who use drugs. Yet, how the locational setting of drug transactions influences public perceptions of drug control policies remains understudied. In particular, the public's view of drug exchanges on the dark web could directly and indirectly influence drug policy, legal decision making, and spending decisions.

The Benefits and Costs of Cybersecurity Risk Reduction: A Dynamic Extension of the Gordon and Loeb Model.

This article develops a dynamic extension of the classic model of cybersecurity investment formulated by Gordon and Loeb. In this dynamic model, results are influenced by the rate at which cybersecurity assets depreciate and the rate of return on investment. Depreciation costs are lower in the dynamic model than is implicitly assumed in the classic model, while the rate-of-return threshold is higher.

The potential harms of the Tor anonymity network cluster disproportionately in free countries.

The Tor anonymity network allows users to protect their privacy and circumvent censorship restrictions but also shields those distributing child abuse content, selling or buying illicit drugs, or sharing malware online. Using data collected from Tor entry nodes, we provide an estimation of the proportion of Tor network users that likely employ the network in putatively good or bad ways. Overall, on an average country/day, ∼6.

The Case against Commercial Antivirus Software: Risk Homeostasis and Information Problems in Cybersecurity.

New cybersecurity technologies, such as commercial antivirus software (AV), sometimes fail to deliver on their promised benefits. This article develops and tests a revised version of risk homeostasis theory, which suggests that new cybersecurity technologies can sometimes have ill effects on security outcomes in the short run and little-to-no effect over the long run. It tests the preliminary plausibility of four predictions from the revised risk homeostasis theory using new survey data from 1,072 respondents.

The Dark Web and cannabis use in the United States: Evidence from a big data research design.

Background: Cannabis is one of the most commonly sold drugs on cryptomarkets. Because of the anonymity-granting functions of Tor, no study has traced the within-country effect of the Dark Web on cannabis consumption patterns. This article uses a big data research design to examine the association between revealed interest in the Dark Web and self-reported cannabis use within US states from 2011 when Silk Road launched to 2015 when Operation Onymous shuttered nine markets.
