Catching Phishers By Their Bait: Investigating the Dutch Phishing Landscape through Phishing Kit Detection

Off-the-shelf, easy-to-deploy phishing kits are believed to lower the threshold for criminal entrepreneurs going phishing. That is, the practice of harvesting user credentials by tricking victims into disclosing these on fraudulent websites. But, how do these kits impact the phishing landscape? And, how often are they used? We leverage the use...

Inadvertently Making Cybercriminals Rich: A Comprehensive Study of Cryptojacking Campaigns at Internet Scale

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...

Inadvertently making cyber criminals rich: A comprehensive study of cryptojacking campaigns at internet scale

Since the release of a browser-based cryptominer by Coinhive in 2017, the easy use of these miners has skyrocketed illicit cryptomining in 2017 and continued in 2018. This method of monetizing websites attracted website owners, as well as criminals seeking new ways to earn a profit. In this paper, we perform two large studies into the world...

Inhibition of a biological sulfide oxidation under haloalkaline conditions by thiols and diorgano polysulfanes

A novel approach has been developed for the simultaneous description of reaction kinetics to describe the formation of polysulfide and sulfate anions from the biological oxidation of hydrogen sulfide (H₂S) using a quick, sulfide-dependent respiration test. Next to H₂S, thiols are commonly present in sour gas streams. We...

Ecology and application of haloalkaliphilic anaerobic microbial communities

Haloalkaliphilic microorganisms that grow optimally at high-pH and high-salinity conditions can be found in natural environments such as soda lakes. These globally spread lakes harbour interesting anaerobic microorganisms that have the potential of being applied in existing technologies or create new opportunities. In this review, we discuss...
