Cyber policy and law enforcement
| French government members urged to switch messaging apps According to newspaper Le Point, France's Prime Minister Elisabeth Borne has invited ministers and members of their cabinets to uninstall “any messaging application” such as WhatsApp, Telegram or Messenger, due to cybersecurity concerns. The head of government asked to instead install Olvid, a more secured application developed in France. | Messaging apps | |
| Rising Cyber Threats in Germany Germany is currently experiencing a significant increase in cyber threats, notably with an exceptionally high risk of ransomware attacks, according to the November 2 report from the German Federal Office for Information Security (BSI). The threat level is described as the highest ever recorded, with an average of 332.000 new variants of malicious software created per day. Ransomware remains the primary cyber threat, and small to medium-sized enterprises, as well as local administrations, are particularly vulnerable. | Threat assessment | |
| Enhanced EU-Ukraine collaboration The European Union Agency for Cybersecurity (ENISA) announced on November 13 its collaboration with Ukraine to enhance cybersecurity through the sharing of best practices. The agreement aims to strengthen the European cybersecurity systems and enables Ukraine to contribute to international policies, leveraging its expertise in Russian cyber operations. This cooperation also involves Ukraine adapting to European cybersecurity standards. | Collaboration | |
