CYBER CRIME & CYBER SECURITY
TRENDS IN AFRICA
Social Media, Scams, & Email Threats
Cyber crime on the continent of Africa has moved far beyond
the notorious 419 Nigerian email scams, coined after the code of
legislation aimed to suppress such scams.15,16 The sophistication
of some attacks and tactics used by cyber criminals demonstrates how vulnerable individuals are online and has chipped
away at public confidence in online security and commerce.
Data breaches, government surveillance, and good old-fashioned scams came together to further encroach on personal
privacy, whether it is personal photos, login credentials or
medical histories.
In 2015, Symantec saw plenty of traditional scams and
malware attacks intended to gather personal information. For
example, one scam promised large numbers of followers for
free on Instagram, while seeking to fool people into revealing
their passwords. Some attacks impersonated tax officials in
an attempt to trick people into downloading malicious email
attachments.
In their simplest form, many scams still rely on the poor security
habits of the general public to succeed. However, we have also
seen how poor website security can expose customer data. In the
latter example, it doesn’t matter how strong a password may be
if the website is vulnerable to a data breach.

TT Manual Sharing – These rely on victims to actually do the work of
sharing the scam by presenting them with intriguing videos, fake
offers, or messages that they share with their friends.
TT Fake Offering – These scams invite social network users to join a
fake event or group with incentives, such as free gift cards. Joining
often requires the user to share credentials with the attacker or

More concerning are attacks in 2015 that made use of sophisticated social engineering to bypass the two-factor authentication
systems designed to safeguard users. By going through a legitimate password-reset process and posing as Google via SMS,
however, one scam was able exploit the public’s trust in a
reputable brand to gain access to email accounts without raising
the victims’ suspicions.
TT Likejacking – Using fake “Like” buttons, attackers trick users into
Social media remains a favored target of scammers, as criminals
seek to leverage the trust people have in their own social circles
to spread scams, fake links, and phishing. To succeed, the social
engineering involved must be convincing, so we have seen more
ingenious tactics being used to dupe potential victims. Social
media is quickly becoming a daily part of life across Africa.
Around 9% of the population uses social media and that number
is growing each year, with South Africans among the world’s
leaders in time spent on social networks at 3.2 hours per day.
