In 2024, France and the world suffered a series of major cyberattacks. Here is a detailed analysis of the ten most striking attacks and their impact.

1. Massive data leak at Viamedis and Almerys

  • Impact: 33 million French insured persons affected.

  • Analysis: The third-party payment platforms exposed sensitive data such as social security numbers. This attack underscores the vulnerability of healthcare infrastructure.

  • Solution: Implement regular security audits and strengthen the encryption of sensitive data.


2. Pro-Russian cyberattack on French ministries

  • Impact: Several ministries paralyzed for 48 hours.

  • Analysis: The DDoS attack carried out by Anonymous Sudan shows that public institutions are prime targets in the context of geopolitical tensions.

  • Solution: Deploy anti-DDoS solutions and diversify network access points to limit impact.


3. France Travail breach

  • Impact: 43 million records compromised.

  • Analysis: The size of this leak highlights weaknesses in the protection of public service data. It is one of the largest breaches in France this year.

  • Solution: Implement intrusion detection systems (IDS) and raise employee awareness of cybersecurity practices.


4. Simone Veil hospital attacked by LockBit

  • Impact: Patient records published online.

  • Analysis: Hospitals are frequent targets because health data is valuable. This attack disrupted care and caused delays in operations.

  • Solution: Secure hospital networks through regular updates and system segmentation.


5. Two London hospitals paralyzed

  • Impact: Transfusions and operations suspended.

  • Analysis: This attack showed that cyber threats do not stop at borders and can affect several countries simultaneously.

  • Solution: Strengthen redundancy of critical systems and business continuity plans.


6. Data leak at SFR

  • Impact: Customer personal data and IBANs exposed.

  • Analysis: This attack highlights the risks associated with the management systems of telecom operators.

  • Solution: Improve multi-factor authentication and continuously monitor sensitive accesses.


7. Cyberattack at Free

  • Impact: Service disruptions and theft of customer data.

  • Analysis: The leak of IBANs increases the risk of banking fraud, eroding consumer trust in operators.

  • Solution: Implement real-time monitoring systems to detect suspicious activity quickly.


8. Infiltration during the US presidential election

  • Impact: Espionage attempts against the Trump and Harris campaigns.

  • Analysis: This attack demonstrates the use of cyberattacks for electoral manipulation and political espionage.

  • Solution: Strengthen the cybersecurity of campaign devices through advanced firewalls and frequent audits.


9. Bitcoin theft by North Korea
