The Evolving Threat: Why Attribution is So Hard

One of the most formidable challenges facing the international community is the difficulty in accurately attributing cyberattacks to specific perpetrators, especially those with suspected state sponsorship. These attackers frequently operate under a cloak of anonymity, severely limiting victims' ability to identify and hold them accountable. This ambiguity not only hinders judicial responses but also restricts the implementation of effective international accountability mechanisms.

Consider the major cyberattack on several Tibetan websites on November 12, 2024. Allegedly backed by the Chinese state, this incident highlighted the growing use of cyberspace as a political battleground and demonstrated that cyberattacks can be strategic tools in political and economic warfare. Despite strong indications of authorship, a lack of conclusive evidence hampered attempts at sanctions or adequate diplomatic responses, underscoring the urgent need for more robust and adaptive attribution mechanisms. Even unintentional incidents, such as the July 2024 faulty update from CrowdStrike that caused widespread disruptions globally, highlight the fragility of our digital world and the interconnected nature of critical operations.

Attack methods are multifaceted and continue to advance:

• Ransomware attacks are a high-profile and growing concern, with damages predicted to hit $265 billion annually by 2031. Ransomware was the leading cause of cyber insurance losses, with business interruption accounting for the largest share of costs. The emergence of "Cybercrime-as-a-Service" and AI-enabled hacking tools will further lower the barriers to entry for ransomware operations.
• Phishing campaigns and data exfiltration events remain prevalent.
• Denial-of-Service (DDoS) attacks increased by 13% in the first two quarters of 2024 and continue to be effective by flooding target servers with fake traffic, rendering them unavailable.
• Business Email/Communication Compromise (BEC/BCC) scams are surging, with global losses exceeding $55 billion over the last decade. The advent of GenAI-powered attacks makes BEC/BCC even more dangerous, capable of highly targeted social engineering attacks, mimicking local accents for vishing, and exacerbating insider threats or vendor email compromise.
• Supply chain vulnerabilities are identified as the "Achilles' heel" of economies and social infrastructure, with 45% of organizations expecting to face significant attacks on their supply chains by 2025. The cost of software supply chain attacks alone is anticipated to rise to $138 billion by 2031.
• Emerging technologies like Artificial Intelligence (AI) and Quantum Computing are shaping the future of cyber threats. AI is becoming both a weapon and a target, enabling attackers to automate and enhance all phases of a cyberattack, from phishing campaigns to zero-day exploitations and malware coding. Meanwhile, quantum computing developments are accelerating, threatening traditional encryption methods like RSA in the future.

Organizations often overestimate their preparedness, leading to a "false sense of security". The reality is that determined attackers continuously develop novel methods to circumvent basic protections like firewalls and antivirus.

Building a Resilient Defense: Incident Response Best Practices

A proactive and comprehensive incident response plan is paramount for significantly boosting your organization’s cyber resilience. It’s about moving beyond isolated breach responses to achieving sustained resilience and the ability to operate through persistent attacks.

Here are key strategies for building that resilient defense:

• Develop Comprehensive Plans and Playbooks:
  • Start with a well-documented and regularly updated Incident Response Plan (IRP) that is customized to your organization's specific risks, critical assets, and operational context, rather than using a generic template. This plan should clearly define roles and responsibilities for incident response team members, communication protocols (internal and external), and step-by-step response procedures for various incident types.
  • Supplement your IRP with detailed, scenario-based incident response playbooks for common cyber threats like ransomware attacks, phishing campaigns, data exfiltration events, Denial-of-Service (DDoS) attacks, and insider threats. Each playbook should outline precise steps, relevant tools, and specific roles, significantly improving preparedness and response efficiency, especially when time is critical. These playbooks must be dynamic and reviewed at least annually or after any major IT or business changes.
  • Ensure your plans are understandable and actionable by using clear, concise language and integrating visual aids like flowcharts. Adopting structured frameworks such as NIST or ISO can help, and leveraging cybersecurity service providers with expertise in Incident Response can aid in crafting effective plans.
• Implement Robust Detection and Analysis Capabilities:
  • Rapid detection is key to minimizing cyber incident impact. This requires deploying and effectively utilizing security monitoring tools, combined with skilled security analysts capable of identifying and triaging suspicious activity.
  • Be proactive with security by actively searching for malicious activity through threat hunting before automated systems detect it, and use threat intelligence to focus your efforts. Consider engaging a Managed Detection and Response (MDR) vendor for 24/7 monitoring.
  • Prioritize incident detection and analysis throughout your organization. Automate initial data analysis using event correlation software and establish clear logging standards and procedures to ensure adequate information is collected and regularly reviewed.
  • Understand normal behaviors of your networks, systems, and applications through profiling, reviewing logs and security alerts, and maintaining a knowledge base of information.
  • Keep all host clocks synchronized using protocols like Network Time Protocol (NTP) to simplify event correlation and maintain evidentiary integrity.
• Define Clear Roles, Responsibilities, and Communication:
  • Establish clear and secure communication channels for timely and accurate information flow during incidents. This includes planning for secure out-of-band internal communications (e.g., in-person, paper) if primary channels are compromised, and strategically managing external communication with customers, stakeholders, regulatory bodies, and the media.
  • A well-defined incident response team needs clearly assigned roles and escalation procedures. This team should include individuals with diverse skills, including technical, operational, strong communication abilities, and a solid understanding of legal and regulatory requirements.
  • Identify and involve other internal groups that may need to participate in incident handling, such as management, IT support, legal, public affairs, human resources, business continuity planning, and physical security. Their expertise and cooperation are essential.
• Practice and Validate Incident Response:
  • The effectiveness of your plan is best validated through regular simulations and exercises, including cyber war games, Red Team exercises, and tabletop wargames. These scenarios allow your team to test roles, identify weaknesses, improve coordination, and build confidence under pressure.
  • Provide ongoing training and education to staff at all levels to recognize and report suspicious activity, as human error is a major factor in breaches. Adequate budgeting for training in technical, security, and legal aspects of incident response is crucial.
• Ensure Rapid Containment and Eradication:
  • After detection, swift action is needed to contain the incident's spread and eradicate the threat. This involves isolating compromised systems to limit damage and prevent data loss, and thoroughly removing all malicious elements.
  • Robust backup and recovery procedures, including regular testing, are essential to minimize downtime and ensure business continuity. Recovery should restore affected systems and data to normal operational status quickly and efficiently.
• Conduct Thorough Post-Incident Analysis (Lessons Learned):
  • Incident closure is a key learning opportunity. Conduct a thorough post-incident analysis of the sequence of events, vulnerabilities, and response effectiveness. Reports should include event timelines, incident impact, response actions, and clear recommendations for future improvement.
  • Meticulous records of incident details, actions, and lessons learned are crucial for continuous improvement and strengthening incident response strategies. This data can also be used to justify funding, identify systemic weaknesses, and track incident trends.
• Manage Third-Party Risks Effectively:
  • Given the interconnected nature of modern business, your incident response plan must include managing incidents involving third-party vendors and partners. This requires clear roles, communication pathways, and response protocols for external entities accessing your systems and data. Supply chain vulnerabilities are a pressing risk, and Cybersecurity Supply Chain Risk Management (C-SCRM) processes should be identified, established, managed, and monitored.
• Leverage the NIST Cybersecurity Framework (CSF) 2.0:
  • The NIST Cybersecurity Framework (CSF) 2.0 provides comprehensive guidance for managing cybersecurity risks. It offers a taxonomy of high-level cybersecurity outcomes categorized into six core functions: Govern, Identify, Protect, Detect, Respond, and Recover. These functions are designed to be understood by a broad audience and are applicable regardless of organizational size, sector, or maturity.
  • The GOVERN Function is central, informing how an organization establishes its cybersecurity risk management strategy, expectations, and policy, and how it prioritizes the outcomes of the other five functions. The framework encourages the creation of Organizational Profiles to describe current and target cybersecurity postures, and CSF Tiers (Partial, Risk Informed, Repeatable, Adaptive) to characterize the rigor of governance and management practices. Utilizing NIST's resources, such as Informative References, Implementation Examples, and Quick-Start Guides, can further aid in implementation.

The Imperative of International Cooperation and Legal Frameworks

Beyond internal organizational resilience, global coordination and legal frameworks are essential to tackling the transnational nature of cyberattacks, especially those backed by state actors.

• Developing International Legal Frameworks: Experts suggest that state-sponsored cyberattacks should, in certain circumstances, be treated similarly to traditional acts of war. This would necessitate updating international law, such as the Geneva Conventions, to include specific rules for cyberattacks, addressing proportionality and distinction between military and civilian targets. However, this faces challenges due to the transnational nature of cyberattacks and the lack of global consensus on applying existing international law to cyberspace.
• Creating an International Court for Cybersecurity: Establishing an international court specializing in cyberwar and cybercrime could significantly facilitate attribution and accountability. Such a court would provide a forum for states and affected parties to present cases, impose sanctions, and develop a uniform jurisprudence on these complex issues.
• Strengthening International Alliances: More robust international cooperation in cybersecurity is vital, particularly for smaller and developing nations, by providing access to advanced cyber defense technologies and expertise. Organizations like the Global Forum on Cybersecurity (GFC) allow countries to collaborate on policies and practices. The Cybersecurity Tech Accord also champions collective action across stakeholder groups to set and enforce meaningful expectations in cyberspace.
• Promoting Education and Global Cyber Awareness: Increasing cyber-risk awareness and training at all levels of citizenship can limit the negative impact of attacks that exploit human vulnerabilities and misinformation. This includes awareness campaigns to counter the spread of misinformation and disinformation, which are increasingly amplified by AI tools.
• Establishing a Global Rapid Response Network: A global "rapid response" network could offer immediate technical and legal assistance to affected countries. This network could involve governments, NGOs, and technology companies to coordinate efforts in mitigating damage and restoring critical infrastructure after an attack.
• Creating Tools, Data Instructions, and Sanctions: States should invest in sophisticated cyber intelligence tools and collaborate to create international data instructions on cybercriminals. A system of international sanctions against states sponsoring cyberattacks, ranging from trade restrictions to blocking access to advanced technologies, could penalize malicious actions in cyberspace.

The Critical Role of Information Sharing and Coordination

Information sharing is a key element in enabling coordination across organizations. Organizations should share incident information throughout the incident response lifecycle, not just after an incident is fully resolved. Sharing information about unusual cyber activity and incidents helps organizations render assistance, provide warnings to prevent others from falling victim, and identify trends that protect the homeland.

• Reporting Requirements: Organizations are encouraged to voluntarily share cyber event information with entities like the Cybersecurity and Infrastructure Security Agency (CISA). For critical infrastructure, the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA) mandates reporting of covered cyber incidents to CISA within 72 hours from the time the entity reasonably believes the incident occurred, and ransom payments within 24 hours. Federal entities receiving cyber incident reports must also share them with CISA within 24 hours.
• Types of Information: Information sharing involves both business impact information (how an incident affects the organization's mission, finances) and technical information (hostnames, IP addresses of attacking hosts, malware samples, exploited vulnerabilities). While business impact information is often shared with higher-level coordinating teams, technical information is crucial for peer and partner organizations to understand and prevent similar attacks.
• Automation and Standardization: Organizations should aim to automate as much of the information sharing process as possible using formal data exchange standards (e.g., IODEF, RID) and technical transport mechanisms.
• Security and Legal Considerations: When sharing, organizations must balance the benefits with the drawbacks of revealing sensitive information, considering data sanitization and Non-Disclosure Agreements (NDAs). It is paramount to consult legal departments before initiating coordination efforts.

Building a Resilient Tomorrow

The cyber landscape is dynamic, and threats will continue to evolve. The goal for every organization should be to foster a resilient defense that can adapt to this constant change, moving beyond isolated breach responses to achieving sustained resilience and the ability to operate through persistent attacks. This requires a proactive and comprehensive incident response plan supported by scenario-specific playbooks, clear communication, continuous learning from past incidents, and the strategic use of technology and external expertise.

It’s time to assess your organization’s incident response strategies for 2025. Are they truly ready for the threats you face? Are your teams prepared? Is there a clear, documented plan in place? If you have any doubts, don't wait until you're under attack to start building your defenses. Engage cybersecurity professionals to review or implement a robust plan. Your future resilience depends on it.
