Microsoft's 2025 security report reveals cybercrime losses in Africa have surged to over KSh 63 billion, with criminals using AI to perfect scams, directly threatening Kenya's digitally-driven economy.

NAIROBI, Kenya - Africa has become a primary testing ground for sophisticated, AI-powered cyberattacks, according to Microsoft's 2025 Digital Defense Report released this week. The report warns that the proliferation of artificial intelligence, deepfakes, and digital impersonation is fueling a new and dangerous wave of cybercrime across the continent, with significant implications for Kenya and the broader East Africa region.
Drawing from an analysis of over 100 trillion daily security signals, the report details a dramatic escalation in financially motivated cybercrime. According to data cited from the World Economic Forum's Cybercrime Impact Atlas 2025, financial losses from cybercrime in Africa more than doubled in the past year, soaring from $192 million (approx. KSh 25 billion) to $484 million (approx. KSh 63 billion). The number of victims also surged from 35,000 to 87,000.
“Africa isn’t just a target — it’s a proving ground for the latest cyber threats,” stated Kerissa Varma, Microsoft’s Chief Security Advisor for Africa, during a virtual presentation on Wednesday, October 22, 2025. “Attackers are now using AI to craft phishing messages tailored to local languages and cultural nuances, impersonate trusted individuals, and exploit the very platforms we depend on.”
The investigation reveals a strategic shift in cybercriminal tactics. While data theft remains the primary objective in 80% of investigated incidents, Business Email Compromise (BEC) has surpassed ransomware as the most financially destructive form of attack. Though BEC schemes constitute only 2% of total incidents, they are responsible for a staggering 21% of successful and costly breaches.
These attacks often begin with phishing to steal credentials, followed by manipulating multi-factor authentication and hijacking legitimate email threads to deceive employees into making unauthorized financial transfers. The report highlights South Africa as a major hub for BEC infrastructure and money mule operations, indicating a growing organization of cybercrime networks on the continent.
Artificial intelligence has become a game-changer for cybercriminals, drastically increasing the efficiency and profitability of their operations. Microsoft found that AI-powered phishing campaigns now achieve a 54% click-rate, which is 4.5 times higher than traditional methods, and can boost profitability by as much as 50-fold.
The report also notes a concerning 195% global increase in the use of AI-generated identities to bypass security verification processes, create anonymous accounts, and launch attacks. This trend makes it harder for Kenyan businesses and individuals to distinguish between legitimate and malicious communications.
Emerging tactics detailed in the report include “ClickFix” scams, where users are tricked into running malicious code, and impersonation via platforms like Microsoft Teams, where attackers pose as IT support to gain remote access to systems.
As a leading digital economy in East Africa with high mobile money penetration, Kenya represents a lucrative target. The trends identified in the Microsoft report underscore the urgent need for enhanced cybersecurity measures for the nation's government institutions, financial services, and small to medium-sized enterprises (SMEs), which are often most vulnerable.
The report identifies government, information technology, and academia as the most targeted sectors continent-wide due to their handling of sensitive data. The rise of AI-crafted phishing in local languages like Swahili could significantly lower the guard of unsuspecting users, making such attacks more effective.
Varma issued a stark warning for regional business leaders. “This is a pivotal moment for African business leaders. Relying on trust alone is no longer enough,” she stated. She emphasized that early warning signs, such as credential theft, must be treated as indicators of potentially larger, more complex breaches.
In response to the escalating threats, Microsoft is promoting its Secure Future Initiative, which aims to help African organizations build resilience by integrating AI-driven defense systems and adopting more secure product design frameworks. The findings serve as a critical call to action for both public and private sectors in Kenya to invest in robust cybersecurity infrastructure, enhance employee training, and foster greater regional cooperation to combat the growing menace of AI-enhanced cybercrime.
