Explanation / Answer
Hoaxes – fake news sent by email:
Probably the first type has to do with hoaxes – false news distributed for different purposes, mainly through email (or social network messages), with misleading content, and which use shocking or sensational topics for propagation. Users normally forward these pieces of news because they either appear to come from a trusted source or because the message itself asks to be forwarded.
The first types of hoaxes usually distributed ads about exaggerated computer threats, news on some web service shutting down or requests to help sick people. On that basis, some of the purposes of this type of scam generally consisted of gathering addresses to send spam, creating uncertainty among recipients or simply having fun.
First email scams:
When it became clear that email would be so far-reaching, the first scams employing this useful tool appeared. Their purpose was mainly to generate anxiety among users, referring, for example, to alleged fortunes, lottery or inheritance that could become theirs if they followed the instructions provided.
After convincing the potential victims, the scam made its appearance. Once the victims fell into the trap, they had to pay an amount of money upfront, as a condition to access the nonexistent fortune. Sometimes the sums required were high, but less so when compared with the supposed benefit the victims would receive afterwards. At this point, perhaps the most representative example is the 419 scam (or Nigerian scam), but is not limited to this country, since there are also other cases where the fraud was translated into Spanish.
Solution:
It is evident that the changes in the way we communicate and interact have also been adapted and adopted by cybercriminals, who are continuously developing new threats. Therefore, we have made this summary to show that as the means of communication have evolved from the traditional postal mail to electronic mails, scams and deceptions have also done so, in accordance with today’s most widely used tools.
Emails became so popular that they also turned into a platform to carry out attacks and propagate threats, from simple hoax messages to the propagation of more sophisticated malicious codes, such as ransomware or macro malware.
