Mixing services try to distort cash flow tracking of cryptocurrencies and obfuscate the origin of customers’ earnings by substituting customers’ cryptocurrency funds with the funds of other customers or the mixers’ private assets. This quality makes mixing services interesting for money laundering, and they are therefore often used by criminals....

Open data promotes transparency and accountability as everyone can analyse it. Law enforcement and the judiciary are increasingly making data available, to increase trust and confidence in the criminal justice system. Due to privacy legislation, judicial open data — like court judgements — in Europe is usually anonymized. And even if the...

We propose a novel, dynamic analysis-based detection solution for formjackers. The operating principle of these formjackers, or card skimmers on the web, is typically simple, yet effective: when making a payment on webshop that has been infected with a formjacker, the submitted payment information is not just transmitted to the webshop, but also...

The emergence of Cybercrime-as-a-Service (CaaS) is a critical evolution in the cybercrime landscape. A key area of research on CaaS is where and how the supply of CaaS is being matched with demand. Next to underground marketplaces and custom websites, cybercrime forums provide an important channel for CaaS suppliers to attract customers. Our...

Dark net markets are a competitive environment. As these anonymous markets enable criminals to trade illicit goods or services, this causes vendors to operate under pseudonyms, rather than real-world identities. The constant battle between market admins and law enforcement makes the typical lifespan of a market two years. When a market...

Many scientific studies and industry reports have observed the emergence of so-called cybercrime-as-a-service. The idea is that specialized suppliers in the underground economy cater to criminal entrepreneurs in need of certain capabilities – substituting specialized technical knowledge with “knowing what to buy”. The impact of this trend could...

Cybercrime thrives and online anonymous markets, or darknet markets, play an important role in the cybercriminal ecosystem. Vendors active on darknet markets invest in security mechanisms to compromise the availability or usefulness of evidence to Law Enforcement Agencies. Therefore, difficulties arise in linking identities or machines to...

A portion of the digital fraud occurring on the dark web comprises the illegal exchange of vouchers, coupons, and stolen accounts, defined in this research as service fraud. Despite its existence, this type of fraud had not been previously explored. This thesis employs a quantitative approach to examine which company characteristics influence...

Hosting providers are theoretically in a key position to combat cybercrime as they are often the entities renting out the resources that end up being abused by miscreants. Yet, notwithstanding hosting providers' current security measures to combat abuse, their responses vary widely. In many cases the response is ineffective, as empirical...

Resources on the Internet allow constant communication and data sharing between Internet users. While these resources keep vital information flowing, cybercriminals can easily compromise and abuse them, using them as a platform for fraud and misuse.

Many cybercriminal entrepreneurs lack the skills and techniques to provision certain parts of their business model, leading them to outsource these parts to specialized criminal vendors. Online anonymous markets, from Silk Road to AlphaBay, have been used to search for these products and contract with their criminal vendors. While one listing of...

Cryptojacking, a phenomenon also known as drive-by cryptomining, involves stealing computing power from others to be used in illicit cryptomining. While first observed as host-based infections with low activity, the release of an efficient browser-based cryptomining application -- as introduced by Coinhive in 2017 -- has skyrocketed...

Digitalization and automation brings many amazing things; games, social media, navigation. However, it also makes us more vulnerable. The facelessness of cyber space and the emancipation of place makes it hard to grasp. Additionally, our personal data becomes more valuable and thereby more lucrative to criminalize. The combination of these...

Victims are often conceptualized as single, human and static entities with certain risk factors that make them more vulnerable and attractive for offenders. This framework is challenged by emerging forms of high-tech cybercrime, such as ransomware, botnets and virtual theft, in which the offender targets a composite of human, technical and...
