Five ways AI is creating everyday risks for African businesses

Five ways AI is creating everyday risks for African businesses

Zawya03-07-2025
In our fast-evolving cyber risk landscape, it's easy to be captivated by the headlines—stories of cutting-edge exploits, wild new attack vectors, and AI's role in shaping malware that once seemed impossible. But while these futuristic threats grab our attention, the real challenge lies in understanding the everyday risks that businesses face and the practical steps to mitigate them.
It's evident that attackers are becoming increasingly inventive. The surge of AI-driven techniques is reshaping the global threat landscape, and Africa is no exception. The continent faces a growing tide of sophisticated fraud schemes, propelled by advancements in generative AI, deepfakes, and internal vulnerabilities. It's a clear call for businesses to rethink their strategies and stay ahead in this advancing game.
And the best place to start is by focusing on the real-world risks. During Trend Micro's recent World Tour in Johannesburg, we unpacked the tangible risks posed by AI advancements and shared actionable insights on how businesses can effectively counter these emerging challenges.
A new wave of AI-powered phishing emerges
We've all seen phishing evolve from poorly worded emails riddled with typos to messages that are polished, professional, and even translated flawlessly into multiple languages. But a more recent development is how attackers now leverage AI to scour social media posts—not just the content of posts but the rich ecosystem of interactions around them. There is a treasure trove of personalised insights that can be mined from comments and connections.
Bad actors are then capitalising on AI's ability to seamlessly craft hyper-personalised messages with astonishing precision. The tools are readily available; even platforms like ChatGPT can be leveraged to generate phishing emails that feel tailored and authentic. This doesn't require advanced coding expertise—it's a straightforward process that puts powerful capabilities into the hands of malicious actors.
The implications are striking. It raises the stakes for businesses as the social engineering pressure through phishing channels continues to intensify, demanding a more vigilant and proactive approach to cybersecurity.
Deepfakes are becoming mainstream
Synthetic media has also entered the conversation, and it's rewriting the rules of social engineering. Deepfakes, once a novelty, are now a mainstream threat. Remarkably, deepfake incidents in Africa increased sevenfold from Q2 to Q4 of 2024 due to advanced AI tools.
With just a few seconds of audio, voice cloning tools can convincingly mimic an executive's voice, enabling fraudsters to issue urgent fund transfer requests that sound all too real. And it doesn't stop there. Real-time face swaps on video platforms like WhatsApp mean that even a casual 'let's jump on a quick call' could be a trap. The line between real and fake is blurring fast, and attackers are exploiting that ambiguity with alarming precision.
Recent headline-grabbing incidents—like last year's Quantum AI investment scam that cost consumers billions—underscore just how high the stakes have become.
AI is exposing deeper gaps in data governance
One of the rising challenges businesses must contend with is the risk of data leakage, especially with tools like AI assistants entering the picture. Imagine an employee—whether inadvertently or with malicious intent—asking for sensitive information such as salary details, acquisition plans, or financial results. If the correct access restrictions are not in place, the AI might serve up restricted data that was never meant for broader access.
What we're seeing here is a classic case of AI inheriting flawed permissions—folders scattered across an organisation with access settings that are far too broad. Perhaps a folder is mistakenly set to 'accessible to everyone' when, in reality, only specific employees should have clearance. AI tools will readily surface information that should remain locked down.
It's crucial to understand that this issue isn't solely about AI; it's a reflection of deeper gaps in data governance and permissions management within organisations.
Open-source is an avenue for malicious code
Another emerging concern around AI lies in the potential for the spread of malicious code. Developers crafting AI applications often rely on open-source repositories or widely used models like Meta's LLaMA. But if these repositories contain buggy or, worse, malicious code, those vulnerabilities can creep into your applications unnoticed. It's a sobering reminder that even the tools we trust can become conduits for risk if not carefully vetted.
Hallucinations can prove catastrophic
Hallucinations are another critical consideration. These occur when AI models, particularly those hastily developed or inadequately vetted, generate information that simply isn't real. Take, for example, OpenAI's Whisper model, used for speech recognition and transcription in medical and business settings. When doctors paused during dictation, the software invented additional words seemingly out of thin air. In a medical context, this isn't just inconvenient—it's potentially catastrophic. It underscores an urgent need for robust quality assurance processes tailored to AI systems.
So, what's the path forward? It starts with visibility—broad, deep, and continuous. Understanding where and how AI is being used across your organisation is no longer optional; it's foundational. Monitor AI interactions closely. Are the prompts or responses raising red flags? That insight isn't just diagnostic—it's an opportunity to intervene, guide, and improve. At the same time, your application security processes must evolve to reflect the new AI-driven threat landscape. And if you're training models, the integrity of your data is paramount. Govern it. Protect it. Own it.
The good news is that defensive AI is outpacing offensive capabilities, thanks to significant investments in talent, tools, and innovation. Even in areas where attackers are advancing—like vulnerability discovery—defenders are using the same techniques to stay one step ahead. And with the rise of agentic AI, we're seeing a shift: more power is moving into the hands of those who protect. The future of cybersecurity isn't just about reacting faster—it's about anticipating smarter. And that future is already taking shape.

Musk's Tesla signs $16.5 billion chip supply deal with Samsung

Tesla CEO Elon Musk said the U.S. automaker had signed a $16.5 billion deal to source chips from Samsung Electronics, a move expected to bolster the South Korean tech giant's loss-making contract manufacturing business. Samsung shares soared nearly 7% after news of the deal on Monday which comes as the world's top memory chip maker faces mounting pressure in the race to produce artificial intelligence chips, where it trails rivals such as TSMC and SK Hynix. Musk said Samsung's new chip factory in Taylor, Texas will make Tesla's next-generation AI6 chip, potentially re-energizing the project that has faced long delays amid Samsung's difficulties in retaining and attracting major clients. "Samsung agreed to allow Tesla to assist in maximizing manufacturing efficiency. This is a critical point, as I will walk the line personally to accelerate the pace of progress. And the fab is conveniently located not far from my house," Musk said in a post on X on Monday. "The $16.5B number is just the bare minimum. Actual output is likely to be several times higher," he said in another post. Shares of Samsung jumped 6.8% to their highest since September last year, while Tesla shares were up 1.9% in U.S. pre-market trading. According to a senior analyst at NH Investment Securities, Ryu Young-ho, Samsung's Taylor fab "so far had virtually no customers, so this order is quite meaningful," although the deal may represent a small portion of its logic chip revenue annually. In October, Reuters reported that Samsung had postponed taking deliveries of ASML chipmaking equipment for its Texas factory as it had not yet won any major customers for the project. It has already delayed the plant's operational start to 2026. It is not clear whether the Samsung-Tesla deal is related to ongoing trade talks between South Korea and the United States. Seoul is seeking U.S. partnerships in chips and shipbuilding amid last-ditch efforts to reach a trade deal to eliminate or reduce potential 25% U.S. tariffs. A South Korean trade ministry official told Reuters he had not heard that the specific deal was part of the trade negotiations. Potential production timeline While no timeline was provided for AI6 chip production, Musk has previously said that next-generation AI5 chips will be produced at the end of 2026, suggesting AI6 would follow. Lee Dong-ju, an analyst at SK Securities, expects production in 2027 or 2028, but Tesla has a history of missing its targets. Samsung currently makes Tesla's AI4 chips, which power its Full Self-Driving driver assistant system, while TSMC is slated to make the AI5, initially in Taiwan and then Arizona, Musk has said. Samsung, the world's top memory chip maker, also produces logic chips designed by customers through its foundry business. The Texas project is central to Samsung Chairman Jay Y. Lee's strategy to expand beyond its bread-and-butter memory chips into contract chip manufacturing. It holds just 8% of the global foundry market, far behind industry leader TSMC, which has a 67% share, data from market researcher Trendforce show. Samsung had earlier announced the $16.5 billion chip supply deal without naming the client, saying the customer had requested confidentiality about the details of the deal, which will run through the end of 2033. Three sources briefed about the matter told Reuters that Tesla was the customer for the deal. Help Samsung's foundry business The deal with Tesla comes as Samsung, which is due to report its earnings on Thursday, faces mounting pressure in the race to produce artificial intelligence chips, where it trails rivals such as TSMC and SK Hynix. This lag has weighed heavily on its profit and share price. Earlier this month, Samsung projected a 56% drop in second-quarter operating profit, partly due to widening losses of its foundry business. Pak Yuak, an analyst at Kiwoom Securities, said the deal would help reduce losses at Samsung's foundry business, which he estimates exceeded 5 trillion won ($3.6 billion) in the first half of the year. Analysts say Samsung has struggled to retain key clients, with many defecting to TSMC for advanced chips, underscoring technological challenges the firm faces in the race to stay relevant in the capital-intensive business. TSMC counts Apple, Nvidia and Qualcomm among its customers.

Inclusive market strategies could transform South Africa's fresh produce sector

South Africa's National Fresh Produce Markets (NFPMs) generate over R20 billion in annual sales, making them a crucial contributor to job creation and food security. However, without meaningful transformation and targeted development strategies, the NFPMs risk falling short of their full potential. The fresh produce sector stands at a critical crossroads. While it remains an engine of economic vitality and nourishment for the nation, it also starkly reflects persistent inequalities. Large-scale commercial farms continue to dominate, yet many small-scale black farmers face systemic barriers that limit their access and growth. Despite its vast potential for driving inclusive economic growth, food security, and employment, the sector's viability is threatened by deep-rooted structural challenges. Systemic barriers facing emerging farmers The challenges confronting emerging farmers are deeply embedded in dynamic systemic impediments and structural issues that are multifaceted. Among the most urgent concerns are the multilayered barriers to entry that these farmers face. Access to suitable land and affordable financing remains a critical obstacle. Without sufficient capital, many aspiring farmers find it impossible to invest in essential inputs such as quality seeds, fertilisers, and modern equipment. This financial limitation not only restricts their productivity but also hinders their ability to compete effectively in the marketplace. Market access is another significant hurdle that many small-scale and emerging-scale commercial farmers struggle to overcome. These farmers often find themselves sidelined from formal supply chains dominated by large retailers and wholesalers. The stringent quality and certification standards imposed by these large entities can be overwhelming, leaving many small farmers unable to meet the required benchmarks. As a result, they become increasingly marginalised and excluded from lucrative market opportunities. The power dynamics within the agricultural sector tend to favour large buyers, effectively stripping small producers of their bargaining power and further entrenching their economic vulnerability. Infrastructure and post-harvest losses Infrastructure deficiencies further exacerbate the challenges faced by emerging farmers. Inadequate storage facilities and poorly developed transportation networks lead to substantial post-harvest losses, which not only diminish farmers' income but also discourage future investment in their operations. The lack of reliable infrastructure creates a detrimental cycle characterised by low productivity and limited market participation, trapping these farmers in a state of perpetual struggle. Moreover, anti-competitive practices within the agricultural sector distort the market landscape. Market concentration, where a handful of large entities control a significant share of the market, can result in price-fixing and other exclusionary behaviours. Such practices stifle innovation and limit consumer choice, collaterally undermining the viability and sustainability of small-scale farming operations. Addressing these interconnected challenges requires a concerted effort from all stakeholders, including government, private sector actors, and civil society organisations. By advocating for policy changes that promote equitable access to resources, improving infrastructure, and fostering a more inclusive market environment, we can work towards empowering emerging farmers and ensuring their essential role in the agricultural sector is recognised and supported. Key interventions for sector transformation Addressing these deep-rooted problems requires a collaborative public-private partnership environment that enables and promotes concerted effort from all stakeholders. Here are some key interventions that could help to foster a more equitable and thriving fresh produce sector: • Policy reform: Government policies must play a central role in levelling the playing field. This includes strengthening competition law enforcement to prevent anti-competitive practices and creating a regulatory environment that supports smallholder farmers. • Infrastructure investment: Investing in rural infrastructure is critical. This means improving roads, storage facilities, and market infrastructure to reduce post-harvest losses and facilitate market access for farmers. • Inclusive market development: Creating more inclusive market systems is vital. This could involve promoting alternative market channels, such as farmers' markets and community-supported agriculture, and encouraging retailers to source produce from small-scale farmers. • Empowerment and inclusion: Special attention must be paid to the inclusion of marginalised groups, particularly women. Addressing gender inequalities in access to land, finance, and markets is crucial for unlocking the full potential of the sector. South Africa's fresh produce sector has the potential to be a powerful engine for inclusive growth and development. By addressing the systemic challenges and fostering a more equitable environment, we can create a sector that not only feeds the nation but also empowers its most vulnerable citizens. 'At Kagiso Trust, we believe transforming South Africa's fresh produce sector requires a systemic approach. Through our SED work, we support emerging farmers via policy engagement, aggregator partnerships, catalytic funding, and inclusive infrastructure solutions. "We are enabling access and building towards a more inclusive and resilient food system," says Quinton Naidoo, head of socio-economic development, Kagiso Trust
