The impact of message framing on end-user security
Evaluating the Effectiveness of Two-Factor Authentication (2FA) in Mitigating Account Takeover Fraud
Account takeover fraud involves cybercriminals using stolen credentials to access online accounts, with financial institutions often targeted due to their monetary value. Despite growing adoption, the effectiveness of cybersecurity measures like two-factor authentication (2FA) remains underexplored. This study evaluates 2FA as a target hardening strategy within the situational crime prevention (SCP) framework. Using a natural experimental design,…
Dude, Where’s My Check? An Osint-Based Analysis of the Link Between Check Theft and Identity Theft
Identity theft targeting American citizens continues to rise. While prior research has linked this trend to data breaches and scams, a more recent development—check theft from U.S. Postal Service (USPS) mailboxes—may also be contributing to the problem. However, the absence of official data connecting check theft to identity theft limits our ability to fully assess this relationship. This paper investigates whether check theft activity observed o…
Crime and Calculation
Drawing on rational choice and social learning theories, this study examines how social networks, subcultural immersion, and specific activities shape dark web actors’ perceptions of risks and rewards. Using original 2024 survey data from 123 active dark web users recruited across English- and Russian-language forums and Telegram channels, we analyze how peer involvement, sustained participation in deviant subcultures, and interest in particular …

The Relevance of Targets’ Sexual Knowledge in the Progression of Online Sexual Grooming Events
Although the typical end goal of an online grooming event is to lure a minor into performing sexual activity (either online or offline), no previous study has examined the relevance of targets’ sexual knowledge on the progression of these events. To address this gap, we deployed two honeypot chatbots which simulated young female users in a sample of twenty-three online chatrooms, over a period of three months. The first chatbot simulated a sexual…
Risk Avoidance Behavior on Darknet Marketplaces
The current study employs a quasi-experimental design to test the efficacy of situational crime prevention (SCP) in understanding risk avoidance behavior in a darknet environment. Specifically, we deployed a web scraper to extract data from a popular darknet market. We then used these data to assess change in vendors and customers’ behavior following the deliverance of a warning message from the market administrator regarding the former market ad…
A Depiction and Classification of the Stolen Data Market Ecosystem and Comprising Darknet Markets
Scant research has investigated the illicit online ecosystem that enables the sale of stolen data. Even fewer studies have examined the longitudinal trends of the markets on which these data are bought and sold. To fill this gap in the literature, our research team identified 30 darknet markets advertising stolen data products from September 1, 2020, through April 30, 2021. We then developed python web scrapers to systematically extract informati…
The Moderating Role of Thoughtfully Reflective Decision-Making on the Relationship between Information Security Messages and SMiShing Victimization
Security messages, as a form of information security awareness training, are designed to encourage individuals to make an informed security decision, reducing their susceptibility to online victimization. To date, no known study has assessed the effectiveness of security messages or whether the effectiveness of these messages varies based on the recipients’ characteristics. Using a randomized controlled trial, this study tests the efficacy of sec…
An Examination of Email Fraudsters’ Modus Operandi
Focusing on two of the most common deceptive strategies employed by fraudsters, we assess which type of cue—politeness or urgency—is more likely to result in an email fraud attempt. We also examine whether these cues are mutually exclusive and consistent throughout the progression of a fraud attempt. To answer our research questions, we posted “for-sale” advertisements on classified-advertisement websites and interacted with fraudsters who respon…
What Money Can Do
With the advent of the internet, romance fraud – or instances wherein individuals use fake identities and sham romantic relationships to defraud others – has moved online. Victims of this crime experience harms to their financial, social, and personal well-being. While researchers have made strides in exploring this crime from the perspective of victims, little research has investigated it using data drawn from the persons committing the crime. M…
Parental guardianship and online sexual grooming of teenagers
The Illicit Ecosystem of Hacking
Over the past four decades, research on hackers has widely propagated within the social sciences. Although this area of scholarship yields rich insight into the interpersonal dynamics of hackers, research on the unique ecosystems they create and inhabit is scant in comparison. The current study aims to offer a more complete assessment of hackers’ ecosystems by incorporating the group affiliations which link hackers to one another. Using 12 months…
The Network of Online Stolen Data Markets
In the face of market uncertainty, illicit actors on the darkweb mitigate risk by displacing their operations across digital marketplaces. In this study, we reconstruct market networks created by vendor displacement to examine how digital marketplaces are connected on the darkweb and identify the properties that drive vendor flows before and after a law enforcement disruption. Findings show that vendors’ movement across digital marketplaces creat…
Malicious Spam Distribution
The distribution of malicious spam occurs in substantial numbers around the globe and can function as a precursor to serious forms of cybercrime. Yet to date, no known study has employed criminological theory to gain insight into the macro-correlates of malicious spam victimization. To address this gap in the literature, the current study utilizes data gathered from multiple sources to assess whether variables derived from routine activity theory…
Restrictive deterrence and the scope of hackers’ reoffending
A Routine Activities Approach to Evidence-Based Risk Assessment
To assess the efficacy of routine activity theory (RAT) for explaining phishing victimization and guide evidence-based policy, we launched two phishing attacks via a university Listserv ( N = 25,875). The first email offered access to a pdf file; the second offered free concert tickets. Several interesting findings emerged demonstrating phishing victimization results from network users’ routine behaviors. Students were significantly less likely t…
Website Defacer Classification
Hackers often engage in website defacement early in their criminal careers to establish a reputation. Some hackers become increasingly prolific and launch a large number of attacks against their targets, whereas others only launch a few attacks before eventually desisting from a life of crime. A better understanding of why some hackers launch a large number of attacks, while others do not, will assist in the implementation of targeted interventio…
Cyber-Dependent Crimes
Online crime has increased in severity and frequency over the past two decades. However, although several scientific disciplines have commonly employed criminological theories to explain this phenomenon, mainstream criminology has devoted relatively scant attention to the investigation of cyber-criminals and their victims. Drawing on this assumption that more criminological attention should be given to this important type of crime, this article p…
Illegal Roaming and File Manipulation on Target Computers
Research Summary The results of previous research indicate that the presentation of deterring situational stimuli in an attacked computing environment shapes system trespassers’ avoiding online behaviors during the progression of a system trespassing event. Nevertheless, none of these studies comprised an investigation of whether the effect of deterring cues influence system trespassers’ activities on the system. Moreover, no prior research has b…
On the Relevance of Spatial and Temporal Dimensions in Assessing Computer Susceptibility to System Trespassing Incidents
We employ knowledge regarding the early phases of system trespassing events and develop a context-related, theoretically driven study that explores computer networks’ social vulnerabilities to remote system trespassing events. Drawing on the routine activities perspective, we raise hypotheses regarding the role of victim client computers in determining the geographical origins and temporal trends of (1) successful password cracking attempts and (…
Collective efficacy and the contingent consequences of exposure to life-threatening violence
Neighborhood research has increasingly emphasized the potential for contextual characteristics to moderate the effects of youths' experiences on their outcomes. Drawing on collective efficacy theory, we examine the variable consequences of youths' exposures to life-threatening violence across neighborhoods. We argue that strong community normative orientations supporting the control of violence diminish the negative effect of exposure to severe v…
Restrictive Deterrent Effects of a Warning Banner in an Attacked Computer System
System trespassing by computer intruders is a growing concern among millions of Internet users. However, little research has employed criminological insights to explore the effectiveness of security means to deter unauthorized access to computer systems. Drawing on the deterrence perspective, we employ a large set of target computers built for the sole purpose of being attacked and conduct two independent experiments to investigate the influence …
Daily Trends and Origin of Computer-Focused Crimes Against a Large University Computer Network
Cybercrime has been the focus of public attention during the last decade. However, within the criminological field, no prior research initiatives have been launched in an effort to better understand this phenomenon using computer network data. Addressing this challenge, we employ the classical routine-activities and lifestyle perspective to raise hypotheses regarding the trends and origin of computer-focused crime incidents (i.e. computer exploit…
Unstructured Socializing, Collective Efficacy, and Violent Behavior Among Urban Youth
Relying on extensions of routine activities and social disorganization theories, we examine whether 1) neighborhood social characteristics shape opportunities for the development of unstructured socializing with peers among adolescents, 2) whether unstructured socializing leads to an increase in violent behavior within urban communities, and 3) whether neighborhood collective efficacy modifies the impact of unstructured socializing on violence. T…
Social Control and Youth Suicidality
Although the suicide rate among U.S. youth between the ages of 10 to 24 dramatically increased during the past 50 years, little research has examined this outcome within larger social contexts of the adolescent environment. Relying on Durkheim's theory of social integration, we examine the effect of individual- and structural-level social integration on adolescents' suicidality. Using a sample of 6,369 respondents within 314 neighborhoods, we exa…
Collective Efficacy, Family Attachment, and Urban Adolescent Suicide Attempts
The suicide rate among American adolescents between the ages of 14-25 has dramatically increased during the last 50 years, and this fact has been the focus of extensive social-scientific investigation. To date, however, research focusing on the joint effects of mental health, family, and contextual-level predictors on adolescents' suicidal behaviors is scarce. Drawing on Durkheim's classic macro-level approach to suicide and collective efficacy t…

Exposure to Violence in Adolescence and Precocious Role Exits
Adolescents' Violent Victimization * in the Neighbourhood
Although recent research demonstrates the relevance of situational and structural-level processes in determining youth violent victimization, only scant attention has been given to these processes’ potential interactions. Accordingly, we study the interactive effects of unstructured socializing with peers, peer group orientation and neighbourhood social processes on adolescents’ violent victimization experiences in their neighbourhoods. Incorpora…

Severe Sanctions, Easy Choice? Investigating the Role of School Sanctions in Preventing Adolescent Violent Offending
Although schools in the United States adopted harsher disciplinary policies in the early 1990s, to date, there is little evidence showing whether severe school sanctions against student misconduct prevent crime. Drawing on both deterrence and rational choice theories, we test the proposition that harsh school‐based policies against violence reduce students’ involvement in violent behavior. However, in contrast to prior research that explores the …
