High Ransomware Threats Targeting English-Speaking Countries

A recent report from Nozomi Networks Labs has brought to light alarming statistics regarding ransomware activities globally, particularly focused on English-speaking nations. The security landscape is increasingly perilous, with a shocking 70% of ransomware exploits aimed at these regions, emphasizing the need for enhanced protective measures.

Key Findings from the Report

In the latter half of the previous year, 40% of all ransomware assaults were directed at companies within the United States, while attacks against the United Kingdom and Canada made up about 30% cumulatively. The economic ramifications of these attacks cannot be understated, as these three countries combined account for nearly 30% of the world’s GDP. Thus, any successful ransomware operation here poses substantial risks for macroeconomic stability and business continuity.

As threat actors embrace generative AI to amplify their endeavors, attackers are becoming more sophisticated, dynamic, and unpredictable. The increasing scale and potential success of these malicious operations mean that businesses in English-speaking countries must be particularly vigilant and prepared.

Wireless Network Vulnerabilities

Another critical area highlighted by the report is the burgeoning threat posed by unsecured wireless networks. Nozomi discovered that a startling 68% of the wireless networks monitored in industrial and critical infrastructure lacked necessary Management Frame Protection (MFP), despite employing contemporary encryption methods. Furthermore, merely 2% of organizations had implemented enterprise-level authentication solutions like 802.1X.

The reliance on Pre-Shared Key (PSK) authentication remained prevalent, with about 98% of observed networks depending on it. This model, suitable for casual environments like cafes, is inappropriate for industrial settings where accountability is crucial. The ease of shared credential use creates significant risks, allowing adversaries to exploit long-term access once credentials are compromised.

Sector-Specific Threats

The transportation sector was identified as the most targeted industry in 2025, particularly vulnerable during both halves of the year. Close behind were manufacturing and public services, which similarly experienced a surge in attacks. Noteworthy is the rise in assaults on public sector organizations, attributed largely to escalating geopolitical conflicts that have provoked a notable uptick in nation-state-related activities and politically motivated hacking (hacktivism).

Scattered Spider's Rising Threat

A particularly concerning finding in Nozomi’s report is the dominance of the hacker group Scattered Spider, which accounted for nearly 43% of all recorded attack alerts in the latter half of the year. Other active groups included Kimsuky from North Korea, APT29 from Russia, and CURIUM from Iran. The report underscores a growing trend of worrying activity from China, Iran, and Russia, which are expected to remain pivotal focal points in cyber threat monitoring for the coming year.

Recommendations for Strengthening Cyber Defenses

Nozomi Networks' Director of Cybersecurity Strategy, Chris Grove, emphasized the urgency of adopting a proactive approach towards securing critical infrastructures. His recommendations include:

• - Establishing asset visibility: Organizations need to have a comprehensive view of their assets and networks.
• - Leveraging AI-driven security systems: These tools can significantly enhance the detection of potential threats and abnormal activities.
• - Risk-based vulnerability management: Prioritizing vulnerabilities based on their potential impact can resourcefully allocate efforts in enhancement.
• - Enabling intelligence sharing: Engaging in cooperative intelligence practices with peers can lead to more robust threat readiness and response.

As ransomware continues to evolve, businesses must remain adaptable and responsive to the changing landscape of cyber threats. The detailed findings in Nozomi Networks' "OT/IoT Cybersecurity Trends and Insights" report serve as an essential guideline for those aiming to bolster their overall security frameworks and protect critical assets against relentless cyber threats.
