Intelligence Report: France National Cybersecurity Agency Reports Ransomware Attack Drop in 2025

1. BLUF (Bottom Line Up Front)

The French Cybersecurity Agency (ANSSI) reported a slight decline in ransomware attacks in 2025, attributed to successful law enforcement operations and preventive measures. Despite the decrease, ransomware remains a significant threat, particularly to SMBs and healthcare and education sectors. The overall confidence in this assessment is moderate due to limited data on the full scope of cyber threats and potential underreporting.

2. Competing Hypotheses

• Hypothesis A: The decline in ransomware attacks is primarily due to effective law enforcement operations and preventive measures by cybersecurity agencies. Supporting evidence includes ANSSI’s report of successful operations like Operation Endgame. However, uncertainties remain about the full impact of these operations on the broader cybercriminal ecosystem.
• Hypothesis B: The decline in reported ransomware attacks may be due to changes in cybercriminal tactics, such as a shift towards encryption-less extortion methods, which are less frequently reported. This is supported by ANSSI’s observation of limited encryption-less attacks, but contradicts vendor warnings of an uptick in such activities.
• Assessment: Hypothesis A is currently better supported due to direct evidence of law enforcement impact, such as Operation Endgame. However, ongoing monitoring of cybercriminal tactics is necessary as shifts could alter the threat landscape.

3. Key Assumptions and Red Flags

• Assumptions: Law enforcement operations have a direct and measurable impact on reducing ransomware attacks. Cybercriminals have not significantly shifted tactics to avoid detection.
• Information Gaps: Detailed data on the effectiveness of specific law enforcement operations and the extent of underreporting of ransomware incidents.
• Bias & Deception Risks: Potential bias in ANSSI’s data due to reliance on reported incidents, which may not capture all ransomware activities. Cybercriminals may exaggerate or fabricate data exfiltration claims.

4. Implications and Strategic Risks

The reported decline in ransomware attacks could lead to complacency in cybersecurity measures, while shifts in cybercriminal tactics may go undetected. This development interacts with broader dynamics of evolving cyber threats and international cooperation in law enforcement.

• Political / Geopolitical: Enhanced international cooperation in cybersecurity could strengthen diplomatic ties but may also provoke retaliatory cyber activities from adversarial states.
• Security / Counter-Terrorism: A decrease in ransomware attacks may temporarily reduce the operational burden on cybersecurity agencies, but vigilance is required to detect new threats.
• Cyber / Information Space: The shift towards encryption-less extortion could complicate detection and reporting, necessitating adaptive cybersecurity strategies.
• Economic / Social: Continued targeting of SMBs and critical sectors like healthcare could have destabilizing economic and social effects if not adequately addressed.

5. Recommendations and Outlook

• Immediate Actions (0–30 days): Enhance monitoring of cybercriminal forums for shifts in tactics, increase awareness campaigns for SMBs, and strengthen public-private partnerships in cybersecurity.
• Medium-Term Posture (1–12 months): Develop resilience measures for critical sectors, invest in cybersecurity training, and expand international law enforcement collaboration.
• Scenario Outlook:
  • Best: Sustained decline in ransomware due to effective international cooperation and adaptive cybersecurity measures.
  • Worst: Significant increase in undetected cyber extortion due to shifts in tactics and inadequate response.
  • Most-Likely: Continued moderate decline in ransomware with periodic spikes due to adaptive cybercriminal strategies.
