These emails have been made to seemed like they have been coming from the sufferer, however have been directions for unauthorized cash transfers from Okpe and his co-conspirators.
These assaults, referred to as enterprise electronic mail compromise assaults, are a type of spearphishing. Whereas common phishing assaults contain casting the web extensive and goal unknown victims, spearphishing takes goal at a particular particular person or group of individuals.
