Euro Digital: cybersecurity challenges, offline wallets and defense against cyberattacks in Europe

The Digital Euro, promoted by the European Central Bank (ECB), is getting closer to becoming a reality. Designed to complement cash and offer a public alternative to private payment systems, the project poses major challenges in cybersecurity, especially in the face of cyberattacks and emergency situations such as blackouts or network outages. In this post, we explore risks, best practices and news about digital security, the role of offline wallets and the European road map to protect digital money for citizens and businesses.

‍

Why does Europe need the Digital Euro?

• The Digital Euro seeks to preserve the role of public money in the face of the fall in the use of cash and the proliferation of private and foreign payment systems, such as cryptocurrencies and stablecoins.
• It will allow instant, secure and fee-free payments across the eurozone, even for those who don't have access to advanced digital solutions.
• The ECB emphasizes the privacy and protection against cyberattacks as cornerstones of the project.

Cybersecurity: main challenges for the Digital Euro

• Armored infrastructure: The ECB is investing in advanced AI and post-quantum cryptography to detect threats and secure both banks and digital wallets against ransomware attacks, malware or massive fraud.
• Offline wallet protection: One of the great innovations is the possibility of operating with digital euros offline (“offline wallets”), allowing instant payments and transfers even in emergencies such as blackouts, cyberattacks or a payment network crash. However, storing balance on physical devices (smartphones, cards, pendrives) opens up new scenarios of theft and direct manipulation of funds.
• Mitigating digital and physical theft risks: Although the wallets will be linked to the identity and must be able to recover funds in the event of loss, the operation of the recovery or blocking processes in the event of theft, nor the response to “zero-day” vulnerabilities or sophisticated fraud, has not yet been fully detailed.
• Updates, monitoring and auditing: The technical environment must be programmable, updatable and able to guarantee atomicity (security of transactions such as cash) even when offline, which involves significant logistical and legal challenges.
• Global threats and precedents: The recent multi-million dollar thefts on cryptocurrency platforms underscore the urgency of shielded systems and the constant monitoring of possible attacks by international networks or even State-sponsored groups.

Good practices and safety recommendations

• Strong authentication, access control and robust fund recovery mechanisms for digital wallet users.
• Ongoing audits of the digital euro infrastructure and regular simulations (“digital twins”) to test and correct vulnerabilities.
• Collaboration between banks, technology companies and European public bodies to share alerts and best practices in the face of new threats.
• Training and awareness campaigns for end users and businesses, given the role of social engineering in cyberscams and robberies.
• Requirement of transparency and cyber resilience tests for technology providers involved in the European digital ecosystem.
