MDDR: Cybercrime Losses in Africa Soar 150% to $484 million | Microsoft Warns as AI-Driven Attacks Surge

When Microsoft’s security teams sifted through over 100 trillion daily security signals this year, one story stood out clearly: cybercriminals are getting smarter, faster, and far richer, and Africa has become a frontline testing ground.

According to the newly released Microsoft Digital Defense Report (MDDR) 2025, cybercrime losses in Africa skyrocketed from $192 million to $484 million in a single year, a staggering 150% increase.

The number of victims also more than doubled, from 35,000 to 87,000, underscoring the continent’s growing vulnerability to digital attacks.

“Africa isn’t just a target, it’s a proving ground for the latest cyber threats,” said Kerissa Varma, Microsoft’s chief security advisor for Africa, today during a press conference. “We’re witnessing attackers harness AI to craft phishing messages in local languages, impersonate trusted individuals, and exploit the very platforms people rely on.”

According to her, cybercriminals are trialling emerging tactics, like fake digital IDs, across Africa’s evolving attack surface.

African companies, especially SMEs, are pivotal defenders in the global cyber landscape, highlighting Africa’s unique opportunity to lead in combating new threats and shaping the future of cyberdefence.

AI Turns the Tide of Cybercrime

The report paints a sobering picture of how Artificial Intelligence (AI) is supercharging the cyber underworld. AI-enhanced phishing campaigns now achieve a 54% click-through rate,  more than four times higher than traditional attacks,  potentially boosting criminal profitability by up to 50-fold.

Microsoft warns that autonomous malware can now move laterally through networks, escalate privileges, and launch attacks without human oversight. Meanwhile, AI-generated IDs used to bypass verification have surged 195% globally, enabling criminals to create synthetic identities and launch deepfake-enabled fraud at scale.

According to the World Economic Forum’s Cybercrime Impact Atlas Report 2025, arrests have increased across 19 African countries.

However, the overall impact of cybercrime escalated sharply: the total value of cybercrime surged from $192 million to $484 million, and the number of victims jumped from 35,000 to 87,000.

Among the growing array of digital threats, Business Email Compromise (BEC) remains the most financially devastating.

Though it accounted for only 2% of detected threats, it was responsible for 21% of successful attacks, surpassing ransomware.

South Africa has emerged as a global hotspot for BEC infrastructure setup and money mule recruitment, with Nigerian-linked groups like Storm-2126 orchestrating cross-border schemes that target real estate firms, law practices, and manufacturers in the U.S. and Europe.

A Call to Rethink Cyber Resilience

Attackers now blend technical exploits, social engineering, and infrastructure abuse in sophisticated multi-stage attacks.

“Relying on trust alone is no longer enough,” Varma cautioned. “Familiar tools can be weaponized. Early warning signs like credential theft must be treated as indicators of larger breaches.”

Microsoft’s Secure Future Initiative, its largest cybersecurity engineering project to date, is designed to help organisations across Africa build resilience against this new wave of AI-powered threats.

“By investing in AI-powered defenses and adopting holistic cybersecurity strategies,” Varma concluded, “Africa can transform from being a target to becoming a defensive powerhouse in the global fight against cybercrime.”

Here’s the Big Picture

• Cybercrime losses in Africa: $192M to $484M (+150%)
• Number of victims: 35,000 to 87,000 (+149%)AI-enhanced phishing success rate: 54% (5× traditional methods)
• AI-generated IDs: +195% globally
• BEC attacks: 21% of successful breaches (highest financial damage)

As cybercriminals turn AI into their most powerful weapon yet, Microsoft’s message is clear: the fight for Africa’s digital future has already begun, and the stakes have never been higher.
