Many users are familiar with the 419 scam, named for the section of Nigeria’s criminal code covering this particular form of fraud. The 419 scam comes in two flavors and is popular among spammers. Advanced fee scams promise gold bullion, lottery winnings, or unclaimed inheritances—provided someone pays a small fee to release those funds. The benefactor—actually the victim who received the spam—will never see the promised items. The above letter represents the second type, where the scammer is in a dire situation and needs help. In this case, the scammer says he or she wishes to escape Liberia because of the Ebola epidemic.
