The study analysed 488 publicly reported cyber incidents, revealing critical vulnerabilities, attack trends, and necessary steps to strengthen cybersecurity resilience in the sector.
Cybersecurity Threats Affecting Financial Institutions
Distributed Denial-of-Service (DDoS) Attacks
- Targeted mainly banks (58%) and government financial websites (21%).
- Often linked to geopolitical events, particularly Russia’s invasion of Ukraine.
- While mitigation strategies have reduced their impact, these attacks still cause significant operational disruptions.
Data Breaches and Leaks
- Primarily affected credit institutions (39%) and other financial service providers.
- Resulted in financial losses, regulatory penalties, and reputational damage.
- Often exploited through supply chain vulnerabilities and social engineering.
Social Engineering Attacks
- Techniques like phishing, smishing, and vishing were used to steal financial data.
- Victims included individuals (38%) and banks (36%), leading to financial fraud and data exposure.
- Attackers increasingly use AI-generated deepfake content to enhance credibility.
Fraud and Financial Crime
- Made up 6% of overall incidents, primarily affecting individuals (40%) and banks (35%).
- Includes investment fraud, bank help desk scams, and crypto-related crimes.
- Underreporting suggests a much larger impact than recorded incidents show.
Ransomware Attacks
- Targeted service providers (29%) and insurance firms (17%).
- Consequences included financial loss (38%), data leaks (35%), and operational disruption (20%).
- Attackers leveraged supply chain weaknesses to infiltrate systems.
Malware Threats
- Banking trojans like Anatsa, Hydra, and Medusa posed serious threats.
- Mobile malware surged, targeting banking apps and customers.
- Affected credit institutions (36%) and crypto service providers (15%).
Supply Chain Attacks
- Affected digital service providers, cloud vendors, and payment processors.
- Resulted in data breaches (63%), operational disruption (26%), and financial losses (11%).
Who Are the Attackers?
ENISA identified three primary groups responsible for these cyber threats:
- Cybercrime Groups – Financially motivated hackers using phishing, malware, and ransomware for extortion and fraud.
- State-Nexus Actors – Government-backed attackers engaging in espionage and financial theft, often targeting crypto-asset service providers.
- Hacktivists – Politically driven groups conducting DDoS attacks on financial institutions, often in response to geopolitical conflicts.
Consequences of Cyber Threats in Finance
The impact of these incidents has been
far-reaching and severe:
- Operational Disruptions (58%) – Service interruptions affecting banks, payment platforms, and trading systems.
- Exposure of Sensitive Data (17%) – Leaked customer and corporate data fueling fraud and cybercrime.
- Financial Losses (13%) – Direct monetary theft, ransomware demands, and regulatory fines.
- Large-Scale Financial Crimes (8%) – Identity theft, unauthorized transactions, and fraudulent investments.
Strengthening Cybersecurity in the Financial Sector
To mitigate these risks, financial institutions must
adopt a multi-layered cybersecurity strategy, including:
- Advanced Threat Detection & AI-Driven Security – Using machine learning for anomaly detection and predictive analysis.
- Regulatory Compliance – Strengthening adherence to DORA, GDPR, and the NIS directive.
- Employee Training & Awareness – Conducting phishing simulations and cybersecurity drills.
- Robust Incident Response Plans – Implementing clear protocols for detecting, containing, and recovering from cyber incidents.
- Multi-Factor Authentication (MFA) – Enforcing strong authentication for both internal employees and customers.
- Third-Party Risk Management – Evaluating cybersecurity controls of vendors and service providers.
- Collaboration & Threat Intelligence Sharing – Engaging in industry-wide cybersecurity forums to exchange insights on emerging threats.
Conclusion
The European finance sector remains a prime target for cybercriminals, hacktivists, and state-backed attackers. Financial institutions must proactively enhance their security measures, improve compliance, and strengthen risk management strategies. By investing in resilience and collaboration, the industry can mitigate financial losses, protect sensitive data, and ensure operational continuity in the face of rising cyber threats.
