Abstract

Most of cyberscam-related studies focus on threats perpetrated against the Western society, with a particular attention to the USA and Europe. Regrettably, no research has been done on scams targeting African countries, especially Nigeria, where the notorious and (in)famous 419 advanced-fee scam, targeted towards other countries, originated. How- ever, as we know, cybercrime is a global problem affecting all parties. In this study, we investigate a form of advance fee fraud scam unique to Nigeria and targeted at Nigerians, but unknown to the Western world. For the study, we rely substantially on almost two years worth of data harvested from an on-line discussion forum used by criminals. We complement this dataset with recent data from three other active forums to consolidate and generalize the research. We apply machine learning to the data to understand the criminals' modus operandi. We show that the criminals exploit the socio-political and economic problems prevalent in the country to craft various fraud schemes to defraud vulnerable groups such as secondary school students and unemployed graduates. The result of our research can help potential victims and policy makers to develop measures to counter the activities of these criminal groups.
