The number of phishing emails targeting South African companies has increased during 2020, according to 65% of IT teams.
This is one of the findings from a Sophos survey, “Phishing Insights 2021”, which reveals that phishing attacks targeting organisations ramped up considerably during the pandemic, as millions of employees working from home became a prime target for cybercriminals.
“Phishing has been around for over 25 years and remains an effective cyberattack technique,” says Chester Wisniewski, principal research scientist at Sophos.
“One of the reasons for its success is its ability to continuously evolve and diversify, tailoring attacks to topical issues or concerns, such as the pandemic, and playing on human emotions and trust.
“It can be tempting for organisations to see phishing attacks as a relatively low-level threat, but that underestimates their power. Phishing is often the first step in a complex, multi-stage attack.
“According to Sophos Rapid Response, attackers frequently use phishing emails to trick users into installing malware or sharing credentials that provide access to the corporate network.”
The findings also reveal that there is a lack of common understanding about the definition of phishing.
For instance, 66% of IT teams in South Africa associate phishing with emails that falsely claim to be from a legitimate organisation, and which are usually combined with a threat or request for information.
Forty-nine percent consider business email compromise (BEC) attacks to be phishing, and more than one-third (36%) think threadjacking – when attackers insert themselves into a legitimate email thread as part of an attack – is phishing.
The good news is that most organisations in South Africa (96%) have implemented cybersecurity awareness programs to combat phishing. Respondents said they use computer-based training programs (66%), human-led training programs (59%), and phishing simulations (47%).
“The ideal would be to prevent phishing emails from ever reaching their intended recipient,” says Wisniewski. “Effective email security solutions can go a long way towards achieving this, but this should be complemented by alert and primed employees who are able to spot and report suspicious messages before they get any further.”
The Sophos Phishing Insights survey polled 5 400 IT decision makers in 30 countries across Europe, the Americas, Asia-Pacific and Central Asia, the Middle East, and Africa.
