As a flurry of tech startup investment driven by the pandemic tailed off in the second quarter of 2022, funding for startups fell globally by 23%, the largest drop in over a decade. In Africa, however, that funding doubled over the same period. The continent has seen a wave of venture capital from within and without, and increasing numbers of ‘unicorns’ – startups valued at over $1 billion. 

For investors, the continent is steadily becoming a safer bet, but certain concerns remain, not least of which is the cyber-reliance of many African nations and businesses. A 2021 report by Interpol suggests that the continent’s GDP is reduced by up to 10% (equivalent to $4.12 billion in 2021) by cybercrime alone. If emerging markets like Nigeria, South Africa, and Kenya are to continue drawing investment, they’ll need to match business innovation with more effective security measures.

The Cost of a Continental Skill Shortage

Cyber skill shortages remain an issue in many Global South markets, meaning the impact of common threats is effectively magnified when they hit organizations in these nations. Having the expertise on hand to reduce time-to-response and take decisive, effective remediation action can be the difference between a bullet point on a threat report and a fully-fledged attack.

Many cyber professionals will think of WannaCry, a ransomware attack which affected over 200,000 devices in 2017, as a threat of the past, its relevance consigned to the months after its first appearance. For countries in Latin America and the Caribbean, however, it remains a prevalent and punishing tool, and continues to target thousands of systems: the highest number of WannaCry attacks are consistently seen in Brazil, Ecuador, and Chile. Why is so much damage still being wrought by a ransomware strain which was largely thrown into obsolescence in the Global North years ago? Think tanks like the RUSI attribute it to a lack of IT professionals and the slow uptake of new security standards in regions which are otherwise enjoying rapid digitalization. 

The discordance between internet penetration rates and cyber security capabilities is even more pronounced in Africa. An estimate made in 2018 suggested that there were only 7,000 certified security professionals in the continent, one for every 177,000 people. In the US, comparatively, the figure was one for every 330 people. Even adjusting for Africa’s reduced internet penetration rate, the figure remains one professional for every 45,140 internet users. 

The result of this is that 9 in every 10 African businesses are said to operate without necessary cyber security protocols in place. If the continent continues to draw investment without making big strides in its cyber security measures, its rapidly growing base of potential victims (Africa’s internet using population numbers over 650 million, massively outstripping North America’s 350 million) will draw increasing numbers of cyber-attacks.

Attackers Destabilize the Market

There is already evidence that attackers are beginning to take notice. Interpol cites a report claiming that in the first months of 2021, African organizations saw the highest increase in ransomware attacks of any region. But it is the efficacy, rather than frequency, of attacks on Global South nations which will be most concerning to investors seeking stability. 

Last year in South Africa, several major trade ports were brought to a halt by a ransomware attack on Transnet and, just a few months later, the country’s justice department was brought down in a similar attack. In Costa Rica earlier this year, the ransomware group Conti successfully locked down several government systems and threatened to overthrow the presiding government if ransom payments were not made, leading President Chaves to declare a national state of emergency. Organizations operating critical national infrastructure are particularly attractive to attackers, as the disruption caused by their downtime makes it easier to extort a generous ransom. These attacks are also high-profile, often internationally so. 

High-profile attacks can greatly affect the confidence of investors and potential business partners. A KPMG report on cyber risks in emerging markets explains: “Those suppliers handling confidential third-party data in emerging markets that are able to demonstrate strong security posture around that data are likely to be more attractive and potentially able to win more business.” Organizations in countries with generally weaker cyber security practices should be looking at tools to put the concerns of potential partners and investors at ease. Ideally these should be AI-driven tools which not only stop old, known threats, but also those headline-grabbing novel attacks and zero days.

Protecting Progress

Many Global South governments are now taking steps to address cybercrime concerns, and bring legislation up to global standards. Last year, South Africa’s President Cyril Ramaphosa signed the Cybercrimes and Cybersecurity Act, placing new breach reporting responsibilities on organizations. Similar acts were passed in nations such as Zambia and Ecuador the same year.

International cooperation on the issue of cyber security is also more common: the Convention on Cyber-security and Personal Data Protection adopted by the African Union's 55 member states in 2014 has now been ratified by thirteen nations, while in July of this year, delegates from Bangladesh, Bhutan, India, Myanmar, Nepal, Sri Lanka, and Thailand gathered for the inaugural BIMSTEC (Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation) meeting on cyber security cooperation. 

These are important steps, but legislation and discussion will do little if organizations do not take action in their wake. As we stressed in our recent blog on modern cyber warfare, the involvement of the private sector in government directives is crucial to tackling widespread cyber threats. Togo’s Minister of Digital Economy stressed this fact when he announced the new African Centre for Coordination and Research in Cybersecurity last month: “Our partnership model with the private sector is an innovative approach that we want to showcase to inspire other countries for safer cyberspace on the continent.”

For emerging markets to thrive globally, the organizations within them need to recognize the growing target on their backs, and protect themselves and their data from increasing numbers of sophisticated cyber-attacks. Addressing crippling skill shortages may seem like a long-term – even generational – plan, but with the right tools it can be done almost immediately. AI solutions like Darktrace can autonomously prevent, detect, and respond to attacks, buying back hours for security professionals, and augmenting the ability of small teams to tackle numerous complex threats simultaneously. Darktrace PREVENT preempts attackers and continuously hardens defenses, ensuring that organizations are prepared for novel threats, rather than falling victim to old ransomware strains.

The economic significance of cyber resilience has become undeniable. With proper security investment, emerging markets and Global South nations can hold onto the billions being lost to cyber-attack costs, and continue to focus on business growth and innovation.

Beyond the Fridge: Exposed Industrial Control Systems

Default blog imageDefault blog image

Introduction

In October 2026, hundreds of supermarkets across France were reportedly affected by a cyberattack targeting their refrigeration systems. According to public reports, the attackers gained access to internet-connected controllers and modified their settings, forcing refrigeration units into high and extremely low temperatures and causing significant disruption. Total losses have been reported to reach several million euros.

The incident drew attention to the security of industrial refrigeration systems, particularly older devices with exposed management interfaces and known vulnerabilities.

The exact details of how the attackers gained access have not been confirmed, however it is speculated that the public-facing web server could be accessed with the username “admin” and password being the current date. Researchers from Claroty’s Team82 identified a vulnerability in Danfoss AK-SM 8xxA Series in 2025, “CVE-2025-41450", allowing for administrative access using a time-based “code-of-the-day" for authentication [1].

Default credentials, outdated firmware and publicly accessible administrative interfaces have been an issue for years. And yet these systems continue to appear in internet scans and require little sophistication to gain admin access. A simple search of internet-connected devices shows a range of exposed devices from Programmable Logic Controllers (PLCs) and remote gateways, to, yes, more fridges.

Darktrace malware researchers identified hundreds of IoT and OT devices publicly exposed on the internet, many of which are configured with no authentication, weak credentials, or default credentials. As shown in Figure 1, an exposed Copeland XWEB web interface, used to manage Dixell equipment, including refrigerators, can provide the ability to remotely control connected devices.

‍

Figure 1: Copeland XWEB interface used to control systems including refrigerators and air conditioning.

However, it’s not only fridges; web management interfaces for industrial controls are also publicly accessible, often protected only by weak credentials. Figure 2 shows an example of a publicly exposed WAGO interface. The WAGO management interface is a configuration and administration panel for controllers. Through it, a logged-in user can view device details and diagnostics, manage user accounts and passwords, update firmware, back up or restore the full configuration, set the clock, and manage SD card storage. While it typically doesn’t manage switch outputs or read live process values, someone with access could still disrupt operation by changing network or Modbus settings, loading bad firmware or configurations, or by resetting passwords and enabling insecure services.

‍

Figure 2: WAGO Management interface.

‍

The issue extends beyond management interfaces. During our research, we identified publicly accessible web interfaces belonging to PLCs, including Rockwell Automation Allen-Bradley devices. In each case, the risk arises from how the devices have been deployed and configured, not from a flaw in the vendors’ products.

‍

Figure 3: Web interface for Allen-Bradley CompactLogix controller.

‍

Figure 3 shows the web interface of an Allen-Bradley CompactLogix controller. Unlike the previous examples, this interface provides a view into the controller's operation, including running tasks, network connections, memory usage and diagnostic information. Rockwell Automation's CompactLogix controllers are commonly used to automate industrial processes, from manufacturing and packaging lines to water treatment and material handling systems. Depending on their configuration, these controllers can operate motors, pumps, valves and other physical equipment.

Although in this example the interface shown does not provide direct control over the PLC's logic, it exposes information about the model, firmware, network layout, and connections, which is useful reconnaissance for a bigger attack.

The concern is not necessarily that every exposed interface allows an attacker to immediately manipulate industrial processes. However, these devices are accessible from the public internet in the first place, providing information about systems that may be responsible for controlling physical equipment.

The attacks on refrigeration systems in France highlight the consequences of poorly secured industrial devices. As demonstrated throughout this research, publicly accessible management interfaces are not limited to refrigeration controllers but extend to PLCs and other systems used to manage industrial equipment.

Finding these devices requires little effort. Internet scanners make it possible to identify publicly exposed interfaces quickly, and in some cases these interfaces rely on publicly documented default credentials or have no authentication at all. As attackers increasingly use AI tools, such attacks may be identified and carried out faster and at a greater scale.

The consequences of this access depend on the device and the functionality exposed. While some interfaces provide little more than diagnostic information, others allow users to modify configurations, disrupt communications, or change settings that affect physical equipment. In industrial environments, this can result in operational downtime, damaged equipment and financial losses.

Weak passwords, default credentials and exposed administrative interfaces are not new security issues. Yet their continued presence on internet-connected industrial systems demonstrates how easily preventable weaknesses can leave physical operations vulnerable to attack.

Exposed devices often come from third-party suppliers and contractors, who frequently install refrigeration controllers, gateways and PLCs without the organization ever being aware they are connected to the internet. Asset visibility remains an important foundation, but organizations should assume that some unknown assets and services will exist. Effective security therefore also depends on continuous monitoring, anomaly detection, network segmentation and rapid response, so that risky exposure and unusual activity can be identified and addressed before it becomes disruptive.

Why Kubernetes Security Needs A Behavioral Approach

Man at computerDefault blog imageDefault blog image

Kubernetes has become a foundational technology for modern cloud-native infrastructure. It can orchestrate everything from customer-facing applications to data pipelines and, increasingly, AI workloads. This is due to the highly scalable nature of Kubernetes, making it cost efficient and reliable.

Gartner projects that by 2028, 95% of new AI deployments will run on Kubernetes, up from less than 30% today1. However, the same qualities that make Kubernetes powerful also make it uniquely challenging to secure, leaving many organizations with limited visibility into their clusters. This lack of visibility increases risk - it’s difficult to secure what you can’t see.

However, this risk is often looked at as purely a posture management challenge. While Cloud Security Posture Management (CSPM) solutions can tell you how a cluster should be configured, they don’t tell you what it is doing in real time. This requires runtime behavioral monitoring of clusters to detect active threats.

Yet existing approaches to securing Kubernetes by most Cloud Detection and Response (CDR) and Network Detection and Response (NDR) vendors often have limited coverage or require a third-party integration to forward traffic and metadata. This means that capabilities can be limited and detections can lack the context of the wider environment, which slows down triage, investigation and response.

Why Kubernetes is hard to secure

Traditional security tooling was built for persistent, long-term infrastructure such as servers and virtual machines with fixed identities that last months or years. Some elements of Kubernetes environments can have a much shorter lifespan, breaking many assumptions those tools rely on:

  1. Increased complexity
    1. Kubernetes environments can be complex in comparison to traditional infrastructure, with many different elements to consider such as nodes, clusters, containers, pods and the workloads themselves.
  2. Ephemeral by design
    1. Kubernetes pods can spin up and terminate in seconds. A container that was compromised may no longer exist by the time a deeper investigation is required, leaving no artifact to analyze. This poses a unique challenge for security operations.
  3. Weaker workload boundaries
    1. Kubernetes containers use lightweight, shared-kernel isolation rather than separate virtual machines, improving efficiency but reducing separation between workloads and the host. As a result, a compromised container may have a greater potential impact on the node and neighboring workloads than a compromised virtual machine (VM).2
    2. Recent vulnerabilities have shown that threat actors can escape a container and gain access to the underlying host.3, 4
  4. Everything is API-driven
    1. Dozens or hundreds of microservices communicate over internal APIs, and the Kubernetes control plane itself is an API. This creates a large and dynamic attack surface, making it difficult to distinguish legitimate activity from malicious behavior.
    2. Without identity-aware runtime visibility, threat actors can move laterally between pods and exploit misconfigured role-based access controls (RBAC) with little chance of detection.

Rising to the challenge of securing Kubernetes

With the release of Darktrace 7.2, Darktrace / HYBRID NETWORK can extend behavioral security into Kubernetes, delivering visibility, detection and response capabilities across runtime activity. Darktrace addresses the challenges of securing Kubernetes environments in several ways.

Behavioral detection, not static rules

Many Kubernetes runtime tools rely on predefined rules and signatures - a fixed list of “bad” behaviors to match against. That approach struggles with novel attacks and generates noise at scale. Darktrace takes a different approach: our Adaptive AI builds a Unique Behavioral Profile for each organization from the ground up, learning the normal behavior of every workload, node and identity in your cluster. It then uses this understanding to detect meaningful deviations from expected behavior, which serves as the basis for surfacing suspicious and malicious activity.  

A pod reaching out to an unfamiliar destination, an unexpected executable launching inside a workload, or an identity performing an action it has never performed, all surface as anomalies without anyone having to write a rule in advance.

Darktrace surfaces unexpected Kubernetes activity that does not align with an organization’s Unique Behavioral Profile

‍

Visibility across the network, the process, and the control plane

Darktrace monitors Kubernetes at three levels that together provide comprehensive runtime visibility:

  1. Network-layer
    1. Traffic between pods, across nodes and out to the internet. This helps to detect lateral movement and unusual connectivity, whether internal or external.
  2. Process-layer
    1. What is executing inside your containers. If a process reads a sensitive credential file or spawns an unexpected shell inside a production pod, Darktrace can identify that activity and use it as context for further detections.
  3. Control plane
    1. Activity against the Kubernetes API itself: someone executes a command in a running pod, RBAC changes, or unusual administrative actions. Many high-impact security events involve the control plane, an area that is often less visible to solutions that only analyze or scan network-layer telemetry.

Misconfiguration and vulnerability awareness

Runtime detection is strongest when combined with posture and exposure management. Darktrace surfaces risky pod configurations, such as privileged containers, host networking, and over-permissive service accounts as workloads are deployed, and links CVEs from images to the workloads running them. Security teams can go beyond simply knowing that a vulnerability exists and see exactly where it is in the cluster. When combined with behavior-based detections, this provides invaluable context that can help prioritize incidents and proactively identify areas that need further attention. For example, anomalous workload behavior on its own might not be very interesting to a security team at first, but if that same workload is known to host sensitive data, is known to have critical vulnerabilities associated with it, or is publicly accessible, then this narrative becomes much more suspicious and demanding of their attention.

Darktrace highlights Kubernetes misconfigurations such as privileged containers, host networking, and missing security controls, helping teams prioritize runtime alerts with valuable exposure and risk context

‍

Response, tailored to Kubernetes

Detection is most effective when paired with response. Darktrace can take precise actions on Kubernetes workloads, including blocking a malicious connection at the pod level, helping to safely contain threats while security teams investigate. Response actions can be taken fully autonomously or via a human-in-the-loop process, which is completely configurable depending on the desired level of autonomy and scope. Darktrace is expanding the number of Kubernetes-native response actions to give customers even more flexibility when containing threats.

Forensics that survive the workload

Because containers are so short-lived, evidence disappears fast and this can make it very difficult to answer questions related to the initial detections. Darktrace solves this with Forensic Acquisition & Investigation capabilities that extend to Kubernetes containers, allowing investigations to be triggered manually by an analyst, or automatically from an alert, preserving evidence before the workload is gone.

For incident responders, this addresses a key challenge in container security: being able to answer “what actually happened?” after an ephemeral workload has vanished.

One platform, not another silo

Kubernetes doesn't exist in isolation, and neither should its security. Darktrace correlates cluster activity with the surrounding cloud environment, including AWS, Azure and GCP identities, network activity and cloud assets, allowing analysts to pivot between a Kubernetes workload and its wider context. A single anomalous action can be traced from the control plane to the pod, and from the pod to the cloud identity behind it, all within a single investigation workflow. This can also include alerts from other areas of hybrid infrastructure or third-party sources where relevant, adding more context to investigations and speeding up workflows for human analysts.

Built to deploy easily

Operational complexity can be a barrier to security adoption. Darktrace / HYBRID NETWORK for Kubernetes installs with a single command, and for teams that manage their infrastructure as code, it supports raw manifests so the deployment can live in a Git repository and be managed through existing GitOps workflows. The same deployment approach works across Kubernetes environments in AWS, Azure, Google Cloud, and on-premises infrastructure. Early adopters of Darktrace’s Kubernetes capabilities have highlighted the simplicity of deployment and time to value.

Darktrace can deploy across your Kubernetes environment and wider hybrid infrastructure, while also providing visibility into Kubernetes deployment structure and status

Next steps

Kubernetes environments are dynamic, ephemeral and API-driven in ways that challenge traditional security tooling. With Kubernetes usage increasing due to widespread AI adoption, it is essential to secure Kubernetes environments as part of securing what AI can do. Darktrace / HYBRID NETWORK addresses these challenges by learning normal behavior in Kubernetes environments across network, process and control-plane layers, identifying meaningful threats and enabling targeted response. Combined with the context of wider hybrid infrastructure and forensic investigation capabilities, Darktrace provides visibility into both emerging threats and active incidents.
