The reason why this tactic is so successful is that the letters look incredibly legitimate and usually come as supposedly innocent PDF or Word documents.

However, the main symptom that something might not be right with this email is its appearance in the spam folder. Thus, people should stay away from these emails and opening email attachments only when they are 100% that they are safe.
