Intelligence Report: February 2026 Patch Tuesday includes six actively exploited zero-days

1. BLUF (Bottom Line Up Front)

Microsoft’s February 2026 Patch Tuesday addresses six actively exploited zero-day vulnerabilities, posing significant risks to users and organizations relying on Windows systems. The vulnerabilities primarily involve security feature bypasses and privilege escalation, which could facilitate further cyber-attacks if not mitigated. The most likely hypothesis is that these vulnerabilities are being exploited by sophisticated threat actors to gain unauthorized access and execute malicious activities. Overall confidence in this assessment is moderate due to incomplete information on the exploitation scope and actor attribution.

2. Competing Hypotheses

• Hypothesis A: The zero-day vulnerabilities are being actively exploited by state-sponsored actors to conduct espionage and cyber operations. This is supported by the complexity and potential impact of the vulnerabilities, which align with tactics used by nation-state actors. However, there is uncertainty due to the lack of specific attribution data.
• Hypothesis B: The vulnerabilities are being exploited by cybercriminal groups for financial gain, such as deploying ransomware or stealing sensitive data. This is supported by the widespread use of Windows systems in various sectors, making them lucrative targets. Contradicting evidence includes the sophisticated nature of the vulnerabilities, which may exceed typical cybercriminal capabilities.
• Assessment: Hypothesis A is currently better supported due to the advanced nature of the vulnerabilities and their potential for strategic exploitation. Key indicators that could shift this judgment include emerging evidence of financial motivations or specific attribution to criminal groups.

3. Key Assumptions and Red Flags

• Assumptions: The vulnerabilities are being exploited by actors with significant technical capabilities; Microsoft will release timely patches to mitigate risks; Users will apply patches promptly to reduce exposure.
• Information Gaps: Specific details on the actors exploiting these vulnerabilities and the full scope of exploitation are missing.
• Bias & Deception Risks: Potential bias in attributing sophisticated attacks to state actors without concrete evidence; risk of underestimating cybercriminal capabilities.

4. Implications and Strategic Risks

The exploitation of these zero-day vulnerabilities could lead to increased cyber threats and operational disruptions across multiple sectors. If unaddressed, these vulnerabilities may facilitate broader cyber campaigns.

• Political / Geopolitical: Potential escalation in cyber tensions between states, especially if state-sponsored actors are involved.
• Security / Counter-Terrorism: Increased risk of cyber-attacks on critical infrastructure and government networks.
• Cyber / Information Space: Heightened vulnerability to cyber espionage and data breaches, impacting information integrity and confidentiality.
• Economic / Social: Potential economic losses due to operational disruptions and increased cybersecurity costs for affected organizations.

5. Recommendations and Outlook

• Immediate Actions (0–30 days): Urge organizations to apply the latest patches immediately; enhance monitoring for signs of exploitation; conduct awareness campaigns on social engineering risks.
• Medium-Term Posture (1–12 months): Develop resilience measures, including regular security audits and incident response planning; foster public-private partnerships for threat intelligence sharing.
• Scenario Outlook: Best: Rapid patch adoption reduces exploitation risks. Worst: Delayed patching leads to widespread attacks. Most-Likely: Mixed patch adoption with targeted attacks continuing.
