# Industry News: Africa Remains Global Hotspot for Removable Media Threats in ICS Environments
## Summary
Kaspersky ICS CERT’s Q4 2025 report identifies Africa as the global leader in the percentage of Industrial Control Systems (ICS) computers targeted by threats via removable media (USBs, external hard drives). The report highlights a persistent regional vulnerability in critical infrastructure where "air-gapped" security myths are frequently debunked by physical device penetration.
## Key Details
- **Date:** April 16, 2026 (Reporting on Q4 2025 data)
- **Companies Involved:** Kaspersky ICS CERT
- **Category:** Market Analysis / Threat Intelligence
## The Story
The report details a recurring trend in the African industrial sector: while internet-based attacks are common globally, Africa consistently shows a disproportionately high rate of malware blocked from removable media. This suggests that despite the physical isolation of many industrial sites across the continent, the reliance on external drives for data transfer, maintenance, and software updates remains a primary attack vector. The malware identified often includes legacy worms and sophisticated data-stealing Trojans, indicating both a lack of basic "cyber hygiene" and targeted interest from local and international threat actors.
## Business Impact
### For the Companies Involved
- **Kaspersky:** Solidifies its position as a primary authority on industrial cybersecurity in emerging markets, leveraging its deep visibility into non-Western threat landscapes to drive global intelligence sales.
### For Competitors
- **Competitive landscape impact:** Global vendors (e.g., Claroty, Nozomi, Dragos) face pressure to enhance "on-disk" and endpoint protection specifically for offline environments, moving away from purely network-based monitoring.
### For Customers
- **Impact on end users:** Industrial operators in Africa face increased operational risks, including potential downtime and equipment damage if "sneakernet" vulnerabilities are not addressed through strict policy and technical controls.
### For the Market
- **Broader market implications:** The data underscores a "digital divide" in security maturity. While developed markets focus on cloud-to-edge security, the African market requires a renewed focus on fundamental physical security and endpoint-based threat prevention.
## Technical Implications
The threats often bypass traditional perimeter defenses by entering via "safe" devices used by third-party contractors or maintenance staff. Technically, this necessitates the implementation of "Sheep Dip" stations (isolated scanning kiosks) and the hardening of USB ports on Engineering Workstations (EWS) and Human-Machine Interfaces (HMIs).
## Strategic Analysis
- **Market Positioning:** Africa is emerging as a critical growth market for cybersecurity, but one that requires localized strategies rather than "one-size-fits-all" Western solutions.
- **Competitive Advantage:** Vendors who can offer effective, low-latency protection for legacy systems that are rarely patched will win market share in this region.
- **Challenges:** High levels of pirated software and the use of personal devices in corporate environments remain significant cultural and structural hurdles.
## Industry Reactions
- **Analyst opinions:** Analysts note that the "permanent leader" status for Africa in this category is a wake-up call for global supply chains, as many raw materials and energy resources originate from these vulnerable infrastructures.
- **Expert commentary:** "The persistence of USB-borne threats in Africa is a systemic failure of air-gap integrity," notes one lead ICS consultant.
## Future Outlook
- **Predictions:** Expect a surge in local regulations across Africa (similar to South Africa’s POPIA but focused on critical infrastructure) forcing industrial operators to adopt stricter hardware-access controls.
- **What to watch for:** Increased investment from Chinese and European security firms vying for dominance in the African industrial sector.
## For Security Professionals
Practitioners should prioritize **Removable Media Control (RMC)** and **Device Control policies**. In environments where internet connectivity is limited, ensuring that offline antivirus signatures are updated via secure, verified channels is critical. Security teams must treat every third-party maintenance laptop as a potential breach vector.
