Key findings: 53% of Africans surveyed think that trusting emails from people they know is good enough; 28% have fallen for a phishing email and 50% have had a malware infection; 64% don’t know what ransomware is and yet believe they can easily identify a security threat; 52% don’t know what multi-factor authentication is.
The 2019 KnowBe4 (http://www.KnowBe4.com) African Report across South Africa, Kenya,
Nigeria, Ghana, Egypt, Morocco, Mauritius and Botswana has found that people
living on the continent are not prepared for the cyber threat. 65% of
respondents across all eight countries are concerned about cybercrime.
They are vulnerable, as they’re not aware of
what they don’t know. From ransomware to phishing to malware and credential
theft, users are not protecting themselves adequately because they mistakenly
think they’re informed, ready and prepared. Around 55% believe that they would
recognise a security incident if they saw one.
Of all the countries surveyed, Kenyans (75%) and
South Africans (74%) were the most concerned about the risk of cybercrime and
yet respondents were comfortable giving away their personal information as long
as they understood what it was being used for (Kenyans 26.59% and South
Africans 57%). It’s a worrying trend – many phishing scams will use any means
necessary to tease out valuable nuggets of personal information and phone calls
or emails from so-called ‘trusted sources’ are among the most common methods
used.
The Risk of Not Knowing What I Don’t Know
The problem is that most users are not aware of
how cyber criminals operate and the tools that they use. More than half of
respondents across all eight countries felt very confident that they would
recognise a security incident or issue if they saw one, but a significant
percentage have had a PC infection, and more than a quarter had fallen for a
scam. In South Africa, 50% of respondents had their PCs infected, while in
Kenya, Ghana and Egypt, this number rose to 67%.
The KnowBe4 survey found that even
though nearly half of respondents across all eight countries felt that their
organisations had trained them adequately, a quarter of them didn’t know what a
ransomware was. For South Africans, a worrying 31.5% thought that a cyberthreat
that encrypts files and demands payments was a Trojan virus and 26.9% of
Kenyans agreed. Egypt and Morocco thought it was a drive-by download, while
Ghana thought it was a botnet.
More than 50% of respondents are not aware of
what multi-factor authentication is or the benefit thereof. Using stolen
credentials was the third most common attack vector used in successful breaches
and applying multi-factor authentication, which is combining your password with
something that you own, such as a One-Time-Password app on your phone, which
reduces this risk significantly.
Phishing Still Number One Attack Vector of
Successful Data Breaches
Email security is one of the biggest threats
facing the average user, both at work and at home, and it is one of the most
common communication methods — more than 70% of those surveyed use email to
collaborate with friends and colleagues. Most people don’t realise what a risky
email looks like or how their actions can result in their systems becoming
infected. While more than half of respondents in Botswana, Egypt, Kenya, Ghana,
Morocco and Mauritius have enough security smarts to avoid clicking on links or
opening attachments they don’t expect, a startling 46% still trusted emails
from people they knew. In South Africa, those statistics are completely turned
around – more than half of respondents (52%) trust emails from people they
know, while only 49.5% don’t open attachments they have not expected.
Email remains one of the most successful forms
of cyber attack today for this very reason. People are quick to click on links
or attachments sent to them from people who they know, not realising that cyber
criminals have potentially hacked or spoofed (impersonated) their friend’s,
colleague’s or suppliers’ systems to spread malware, or launch other forms of
attacks. Cyber criminals can easily mimic contact lists or use email addresses
that look as if they’ve come from trusted institutions, and a simple click can
unleash a ransomware attack that can hold an entire company, government or home
hostage. According to Verizon’s 2019 Data Breach Report, email phishing is till
the number one attack vector used in successful breaches. Closely followed by
malware infections and the use of stolen credentials – both of which are attack
vectors commonly accomplished via phishing. Phishing and social engineering
attacks are not just limited to email – they have spread to other communication
channels such as WhatsApp and the phone. With WhatsApp use at more than 90% in
Africa, this is a serious concern.
Phishing Myths
Another myth around phishing scams is that they
are badly written with terrible language and rude offers. While these still
exist, they are no longer the norm. Cyber criminals have become incredibly
sophisticated and prey on this lack of understanding. Across all eight
countries, more than a quarter of respondents checked for bad grammar and
spelling to determine whether or not an email was legitimate. Interestingly,
more than a quarter had also clicked on a phishing email. It turns out that
yes, Africa has been phished and will continue to fall prey to this insidious
attack unless they recognise the need for training and a deeper understanding
of security threats.
When looked at against the backdrop of how often
they’ve been caught by a phishing email, it’s clear that users still don’t
realise how easily they can fall prey to a well-designed email.
The biggest concern is that this lack of
awareness around cybersecurity impacts a person’s life, identity and work.
Humans are one of the most common causes of a business being held by ransomware
or crippled by malware, data breaches or plain financial fraud. Their
inadvertent clicking on an attachment, sharing personal information or carrying
an infection into work on their mobile device can cause these types of issues.
People have the hots for public hotspots
The survey found that more than 90% of respondents
used a smartphone and more than 70% used a laptop computer to connect to the
internet, using either data from their mobile network (more than 80%) or through
their home network. However, more than a quarter of respondents connected their
devices to the internet using a free Wi-Fi connection in a public space. This
is risky, as cyber criminals make use of public places to trick people into
connecting to their malicious hotspot in order to connect to the person’s
machine or to steal their information.
Survey highlights urgent need for security
awareness training
For organisations, it has become critical that
they train employees around security best practices and the various
methodologies used by the cyber criminal. People need to stop thinking that
phishing and ransomware only happen to other people or big businesses –
everyone is vulnerable. One of the reasons why spam continues to rise in
quantity is because it works often enough to be of value. According to the
September 2019 Cisco Talos Email and Web
Reputation Centre (http://bit.ly/3bOFo83) report, the average spam volume for the year was
409.51 billion. That’s compared with the paltry 68.90 billion emails that are
legitimate. Spam works because somebody always clicks on the link.
Training in cybersecurity threats,
methodologies, entry points and vulnerabilities has become critical for the
organisation. This not only helps to minimise the growing risk of human error
that’s allowing threats to bypass their complex and powerful security systems,
but helps to protect their employees.
The survey has highlighted the areas that are
most vulnerable and where people need the most help in learning about cyber
threats. Employee training is definitely one of the most important points –
employees are not aware of how their use of free Wi-Fi networks can potentially
infect the organisation, nor are they as aware of email and phishing threats as
they believe. It’s also important to bust some of the most common security
myths. Not all malicious emails are badly written, phishing is sophisticated
and clever, and mobile devices can be infected. The most common platforms used
by respondents to connect with friends and colleagues were WhatsApp (more than
90%) and email (more than 70%), and both of these platforms have been
compromised. Educating users on how to strengthen their password practices by
applying multi-factor authentication is another easy step to significantly reduce
risks.
Education is key to ensuring that employees are
aware of the risks, understand the threats and make more concerted efforts to
protect themselves from infection.
