In technical support scams, cybercriminals attempt to convince users that their machines are infected with malware and are in need of their technical support. In this process, the victims are asked to provide scammers with remote access to their machines, who will then “diagnose the problem”, before offering their support services which typically cost hundreds of dollars.

Particular attention is devoted to a dedicated predicate-argument layer which is used for aligning translationally equivalent sentences of the two languages. We describe both our conceptual decisions and aspects of their technical realisation. We discuss some select...

Abstract Networks of social activists traditionally lack financial and human resources, resulting in low interest in employing sophisticated IT. There are not many studies describing the development and use of computer systems for networks of social activists. Especially with regard to web 2.0 applications, it is interesting to analyze how social activists appropriate social web platforms. In t...
