The modern cyber landscape demands a foundational shift in organizational security posture, moving away from legacy perimeter controls to align defenses with increasingly sophisticated threat tactics. We are observing a convergence of persistent legacy threats and advanced new tactics. It is critical that CISOs and the organization managements refocus their attention to these emerging threats and re-evaluate the cybersecurity posture employed. There are four key areas of emerging risk:
1. Critical Vulnerability Exploitation
Adversaries, particularly state-sponsored actors who drive over half of attributed exploitation campaigns, prioritize low-friction, high-impact attacks. These attacks heavily leverage publicly exposed applications and services for initial access, with nearly 69% of actively exploited vulnerabilities requiring no authentication and 30% enabling Remote Code Execution (RCE).
2. Targeting Edge and Perimeter Infrastructure
Edge-security and gateway products (e.g., SSL-VPNs, next-gen firewalls) are frequently targeted for initial access, given their position grants attackers a privileged, authenticated pathway deep into the corporate environment. Promptly patching these internet-facing systems is crucial.
Ransomware operators and malware groups are employing sophisticated defense evasion techniques, such as "bring-your-own-installer" (BYOI) and custom payloads using mechanisms like JIT hooking and memory injection to bypass Endpoint Detection and Response (EDR) solutions. Furthermore, human factor remains a pressing concern, as employee error accounts for over 80% of data breaches, and social engineering methods like ClickFix trick users into manually executing malicious scripts. Adversaries are also enhancing their persistence using common Remote Access Trojans (RATs) and relying on legitimate tools (such as Cobalt Strike or PuTTY) to blend in with routine administrative activity and evade detection.
4. Third-Party Supply Chain Risk
Cybercriminals are increasingly adopting a "hub and spoke" strategy, targeting mission-critical third-party service providers (the hub) to infiltrate thousands of dependent client organizations (the spokes). The growing complexity of these supply chains makes governing cyber risk critically important.
Approaches to deal with these threats
Strategy & Access Control: The adoption of Zero Trust Architecture (ZTA) is recommended as a foundational shift away from legacy perimeter concepts, ensuring no system, user, or asset is implicitly trusted. This strategy is essential for managing cloud acceleration, supply chain threats, and human factor risk. Management must ensure Multi-Factor Authentication (MFA) is mandatory across all critical accounts (remote access, privileged access, email, VPN). However, MFA is not a complete defense; organizations must augment it with phishing-resistant MFA (e.g., hardware keys) to mitigate sophisticated bypass techniques like MFA fatigue and session hijacking.
Detection & Intelligence: A threat-informed defense requires continuously monitoring and investigating abnormal network activity to detect malicious behavior effectively. Organizations must integrate threat intelligence into security operations and leverage security frameworks like the MITRE ATT&CK to map adversary behaviors (Tactics, Techniques, and Procedures - TTPs) and prioritize defense engineering efforts. Combining MITRE ATT&CK for detailed tactical depth with the Cyber Kill Chain for strategic visibility provides a comprehensive view of such attacks.
Resilience and Readiness: Management must prioritize patch management for critical, public-facing systems, especially edge security devices, to shrink the window of opportunity for exploitation. Furthermore, robust EDR and behavioral analytics are necessary to detect and respond to stealthy malware TTPs like JIT hooking and malicious processes. Incident response (IR) plans must be updated, regularly tested, and clearly communicated to the entire organization. The Board should ensure resources are allocated and 'readied' to maintain critical business continuity in line with the organization's risk appetite in the event of a total loss of core technology systems. Recent major incidents have underscored this urgent need.
Supply Chain Oversight: A dynamic and ongoing Third-Party Risk Management (TPRM) program must be established and governed by a multi-disciplinary committee. This program must identify and prioritize risks posed by every vendor. Contracts must mandate compliance with security standards, requiring vendors to adopt strong security practices, implement regular third party audits and include details on incident reporting responsibilities.
Management must actively align cyber risk with broader business objectives, establishing security as a cultural priority reinforced by strong leadership.
To ensure rigorous oversight, Boards should continuously discuss and review whether the business has adequate cyber resilience to prevent, detect, and respond to cyber attacks.
