Churn, hubs and hybrid fulfilment
Purpose This study aims to examine how drug-market activity on Telegram is organised through digitally mediated but physically grounded practices, and how volatility and partial visibility shape what can be known about these markets. Design/methodology/approach The work uses an iterative, three-level link-tracing scrape of public Telegram channels anchored in city-specific entry points (London/UK and Warsaw/Poland) and conducted in two waves (Mar…
Cross‐Border Online Radicalization Among Teenagers
This article examines the theme of transnationality in online radicalization processes through an empirical case. It focuses on a group called ‘The Kiss’, led by a Portuguese teenager (Micazz) who encouraged individuals to carry out acts of violence in Brazil in 2023. The study sought to answer the following question: What can The Kiss case reveal about the transnationalization of online radicalization processes? To address this question, we cond…
From passion to illegality
The illegal wildlife trade represents a significant threat to biodiversity. Limited research has examined the illegal trade in succulents, plants characterized by their ability to store water in their leaves, stems or roots. The growing popularity of succulents has contributed to the emergence of illicit consumer practices. In addition, the absence of adequate regulatory oversight, combined with the normalization of certain illegal behaviours and…
A Scoping Review of Empirical Studies Addressing the Prevention of Cyberviolence
With the growing use of information technology, individuals are now able to hurt others, often with little recourse due to the anonymity provided in these online spaces. Cyberviolence (CV) can cause significant psychological and even physical harm as it has the potential to spill into the offline realm. Prevention programs have been implemented to address CV among youths, though additional evidence is necessary to inform initiatives that could be…
The effect of a police crackdown on online drug sales
Results suggest that police crackdowns can effectively disrupt for cryptomarkets. Seizing parcels negatively affected vendors' reputation and compromised the trust system on which cryptomarkets are built
From warnings to bans
Communities of Inquiry for Offenders
Malware as a service (MaaS) has become a profitable profession, allowing individuals who are not technologically competent, and criminal organizations, to purchase such malicious software to conduct a variety of attacks. This has created space for those with the technological abilities to make a business off the malware that they write, and it is therefore important to understand where these developers are learning the skills needed. The current …

Online and offline determinants of drug trafficking across countries via cryptomarkets
Drug cryptomarkets are a significant development in the recent history of illicit drug markets. Dealers and buyers can now finalize transactions with people they have never met, who could be located anywhere across the globe. What factors shape the geography of international drug trafficking via these cryptomarkets? In our current study, we test the determinants of drug trafficking through cryptomarkets by using a mix of social network analysis a…
Paths and Counting
Based on the crime script approach, the main objective of this study was to identify steps involved in firearms trafficking in the Province of Quebec, Canada. Our analysis focused on actions performed by actors, facilitating conditions, obstacles and errors for each step of the firearms trafficking process. A deductive thematic analysis was conducted to build the firearms trafficking script with 76 investigation files, conducted between 1996 and …
Illegal Market Governance and Organized Crime Groups’ Resilience
Since its emergence in the early 1990s, the Sinaloa Cartel has effectively surmounted all challenges to its existence, while, simultaneously, successfully developing its illegal ventures in Mexico and beyond. Based on evidence from the accounts of witnesses who testified in the prosecution of Joaquin Guzmán Loera (also known as El Chapo), one of the Sinaloa Cartel’s most prominent figures, we argue that this OCG’s resilience partially derives fro…

The dark web trades wildlife, but mostly for use as drugs
Contemporary wildlife trade is massively facilitated by the Internet. By design, the dark web is one layer of the Internet that is difficult to monitor and continues to lack thorough investigation. Here, we accessed a comprehensive database of dark web marketplaces to search across c . 2 million dark web advertisements over 5 years using c . 7 k wildlife trade‐related search terms. We found 153 species traded in 3332 advertisements ( c . 600 adve…
Like aspirin for arthritis”
Research summary Crackdowns are law enforcement strategies based on the principles of deterrence theory, which stipulates that offenders are rational actors who will refrain from crime if perceived risks are higher than perceived benefits. Studies have shown that the effects of police street drug crackdowns are mostly short termed and followed by considerable displacement. In the early 2010s, an important part of illicit drug trades moved online …
Dark web pedophile site users' cybersecurity concerns
Examining the Uncharted Dark Web
Despite their growing popularity, cryptomarkets generate risks for participants. This has promoted the reemergence of a more personal transaction model on the dark web: single vendor shops. To date, little is known about how single vendors display trust to attract potential customers without relying on the structural trust provided by cryptomarkets' review and escrow systems. A total of 108 single vendor shops were identified. A coding grid was u…
The success rate of online illicit drug transactions during a global pandemic
Anonymity Technologies in Investigative Journalism
Investigative journalism, like other sectors of social life, has undergone significant changes due to globalization, technological progress, and the Western world’s turn to neoliberalism. This context has facilitated the emergence of new practices within the profession, particularly new modes of communication between journalists and their confidential sources. This qualitative study focuses on the meaning journalists attribute to the use of these…
Cryptomarkets and the returns to criminal experience
Criminal capital theory suggests more experienced offenders receive higher returns from crime. Offenders who accrue skills over their criminal career are better able to minimize detection, increase profits, and navigate illegal markets. Yet shifts in the offending landscape to technologically-dependent crimes have led some to suggest that the skills necessary to be successful in conventional crimes no longer apply, meaning ‘traditional’ criminals…

L’effet Covid sur les cryptomarchés
Dans les mois qui ont suivi le début de la pandémie de COVID-19, l’European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) a observé une utilisation accrue des cryptomarchés, ce qui amène les chercheurs à se demander si les cryptomarchés constituent un canal plus pratique pour la distribution des drogues illicites puisqu’il évite le contact physique. Cependant, les mesures pour contrer la propagation du virus ont mené à la fermeture des …
Les interventions policières sur les facilitateurs du crime
Les cryptomarchés sont des plateformes de commerce en ligne spécialisées dans la vente de drogues illicites. Le succès de ces marchés a attiré l’attention de nombreux organismes d’application de la loi à travers le monde, mais leurs efforts coordonnés pour fermer ces marchés et arrêter leurs participants se sont jusqu’à maintenant avérés inefficaces. L’objectif de cette étude est de décrire et de comprendre les impacts d’une récente intervention …
Drug Markets and Anonymizing Technologies
Online drug markets taking advantage of social media and encryption software (e.g. Tor network) and cryptocurrencies (e.g. Bitcoin, Monero) to conceal the identity and physical location of their users are a relatively new area of internet research. Yet, a range of socio-technical innovations have contributed to the proliferation of drug markets on the Internet. Due to the illegality of drugs and drug dealing are anonymizing technologies regarded …
Preliminary findings of the impact of Covid-19 on drugs crypto markets
The social network of hackers
Social researchers are facing more and more challenges as criminal networks are expanding in size and moving to the Internet. Many efforts are currently under way to enhance the technical capabilities of researchers working in the field of cybercrimes. Rather than focusing on the technical tools that could enhance research performance, this article focuses on a specific field that has demonstrated its use in the study of criminal networks: social…
The ecology of trust among hackers
Malicious hackers profit from the division of labour among highly skilled associates. However, duplicity and betrayal form an intrinsic part of their daily operations. This article examines how a community of hackers uses an automated reputation system to enhance trust among its members. We analyse 449,478 feedbacks collected over 27 months that rate the trustworthiness of 29,985 individuals belonging to the largest computer hacking forum. Only a…
Reputation in a dark network of online criminals
This paper focuses on criminals who could easily be labelled as entrepreneurs and who deal in compromised computer systems. Known as botmasters, these individuals use their technical skills to take over and control personal, business and governmental computers. These networks of hijacked computers are known as botnets in the security industry. With this massive computing power, these criminals can send large amounts of spam, attack web servers or…

Cybercrime is whose responsibility? A case study of an online behaviour system in crime
Drawing on Sutherland’s theory of behaviour systems in crime, this study investigates social media fraud (SMF) facilitated by botnets to understand the onset and maturation of this new online offending behaviour. We find legitimate actors in the system – Internet of Things manufacturers, online social networks, hosting companies and law enforcement agencies – share a way of life that prioritises private gains and avoids implicit responsibility fo…

Crime facilitation purposes of social networking sites
There have been growing claims in media circles and law-enforcement settings that street gangs and criminal groups are turning to Internet-based social networking sites for various reasons ranging from the showcasing of their images and exploits to the suspected recruitment of members. The present study investigates whether such a trend is, in fact, in place. The presence of street gangs on these Internet sites is referred to as cyberbanging. Whi…

Policing cybercrime and cyberterror
In Policing Cybercrime and Cyberterror, Thomas J. Holt, George W. Burruss and Adam M. Bossler explore the role and the perceptions of law enforcement in regard to cybercrime and cyberterror. The bo
Hidden wholesale
The cryptomarket may function in part as a virtual broker, linking wholesalers with offline retail-level distributors. For drugs like ecstasy, these marketplaces may link vendors in producer countries directly with retail level suppliers. Wholesale activity on cryptomarkets may serve to increase the diffusion of new drugs - and wider range of drugs - in offline drug markets, thereby indirectly serving drug users who are not cryptomarket customers…

Assessing market competition and vendors’ size and scope on AlphaBay
Six Years Later
Cryptomarkets are online illicit marketplaces where drug dealers advertise the sale of illicit drugs. Anonymizing technologies such as the Tor network and virtual currencies are used to hide cryptomarket participants’ identity and to limit the ability of law enforcement agencies to make arrests. In this paper, our aim is to describe how herbal cannabis dealers and buyers in the United States have adapted to the online sale of herbal cannabis thro…

Les réseaux de coauteurs
La recherche scientifique cherche la plupart du temps à comprendre la nature mais se tourne aussi à l’occasion vers elle-même pour mieux comprendre la genèse des connaissances scientifiques. Cette quête s’est traduite par une littérature importante portant sur les réseaux de collaborations entre auteurs pour produire des textes scientifiques. L’objectif général de cette branche de recherche est d’expliquer la structure des collaborations et de dé…
Nonmedical prescription psychiatric drug use and the darknet
Predominantly, psychiatric drugs with potent sedative, stimulant or euphoriant effects are sold on cryptomarkets and this varies by country. With some caveats regarding the limitations of cryptomarket digital trace data taken into account, the study of trends of these products sold online over time may offer a novel and increasingly important window onto wider drug purchasing habits
Size and scope of the tobacco trade on the darkweb
Globally, tobacco is responsible for the death of approximately 6 million individuals per year. In reaction, governments have enacted tobacco control policies that cope with the harmful effects of the drug. However, these policies have also created geographic price disparities and increased the effort needed to purchase legal tobacco products. The result was the creation of a new illicit tobacco market. While tobacco smuggling continues through c…
