In their 2023 Annual Cybersecurity Report released last week, researchers from Trend Micro, note that the criminals are opting for quality over quantity, seeking higher returns from fewer, more valuable targets in Kenya.
“The nature of these attacks has evolved, becoming more sophisticated and harder to detect,” notes the study in part.
According to Trend Micro, a global cybersecurity platform, the online criminals are on the prowl in Kenya notwithstanding arrests and convictions that have been reported in the media.
“We blocked approximately 37 million email threats, over half a million malicious Uniform Resource Locators (URLs) in the country,” says Gareth Redelinghuys, Country Managing Director for the African Cluster at Trend Micro.
During the same period, more than one million malicious attacks on mobile apps used by Kenyan businesses and consumers were also saved from falling victims. This shift indicates that cybercriminals are opting for quality over quantity, seeking higher returns from fewer, more valuable targets.
"Our latest data shows that threat actors are fine-tuning their operations, shifting away from large-scale attacks, and instead focusing on a smaller range of targets but with higher victim profiles for maximum gain with minimum effort," noted Redelinghuys in a statement to the media.
To achieve their destructing schemes, the cybercriminals use advanced techniques such as Living-Off-The-Land Binaries and Scripts, which use non-malicious files native to operating systems to camouflage their activities.
Global ransomware detections have seen a significant drop from 2021 to 2023, averaging less than half the detections recorded in 2020.
The report also highlights an increase in Trojan FRS threats globally, suggesting that attackers are becoming more adept at bypassing initial detection measures. In 2023, several ransomware families exploited remote and intermittent encryption, as well as unmonitored virtual machines, to bypass Endpoint Detection and Response (EDR) systems.
By using less content during encryption, these attacks minimize the chance of triggering detection mechanisms.
Prominent ransomware groups such as Clop and BlackCat were particularly active last year. Clop exploited major vulnerabilities, while BlackCat launched a new variant and leveraged regulatory requirements to pressure victims into quicker responses.
Email threats in Kenya have also seen a shift towards more sophisticated methods. Although email threat detections decreased from over 66 million in 2021 to 37 million in 2023, the rise in malware detection suggests a strategic shift by attackers.
Rather than indiscriminately targeting large numbers of users, cybercriminals are now conducting more targeted operations, such as Business Email Compromise (BEC) schemes, which are designed to appear legitimate and evade scrutiny.
"IT leaders must refine their processes and protocols to combat these persistent and increasingly sophisticated attacks with efficiency," urged Zaheer Ebrahim, Solutions Architect for the Middle East and Africa at Trend Micro.
"As attacks become more difficult to detect, the cost of successful breaches will rise," added Zaheer.
Kenya through the Computer Misuse and Cybercrime protects its citizens from all kinds of online harassment.
