SecurityScorecard claims 100% of Europe’s top financial services companies have suffered a supply chain breach in the past year
Analysis Summary
# Incident Report: Pervasive Third-Party Supply Chain Compromises Across European Financial Sector
## Executive Summary
Research spanning the past year indicates that 100% of Europe's largest financial firms experienced a security breach originating from a third or fourth-party supplier. While direct organization breaches were lower (18%), supply chain vulnerabilities are identified as a critical and pervasive threat vector exploiting ecosystem weak links. Response actions suggested focus on immediate remediation of poor security hygiene, particularly DNS misconfigurations and endpoint security, ahead of the DORA compliance deadline.
## Incident Details
- **Discovery Date:** Analysis report released sometime before December 17, 2024 (based on research over the "past year").
- **Incident Date:** Occurred throughout the preceding year.
- **Affected Organization:** All major European financial services companies (as assessed by market capitalization).
- **Sector:** Financial Services.
- **Geography:** Europe (Scandinavia, UK, Germany, France, Italy analyzed).
## Timeline of Events
### Initial Access
- **Date/Time:** Continuously over the past year.
- **Vector:** Compromise via third-party and fourth-party suppliers/vendors.
- **Details:** 98% of firms suffered a third-party breach, and 98% suffered a fourth-party breach.
### Lateral Movement
- Not explicitly detailed regarding specific movement within the financial firms, but implied through the supplier chain infiltration leading to impact on the primary organization.
### Data Exfiltration/Impact
- The data type and volume are not specified, but the scope confirms a widespread security risk profile across the entire European financial sector due to supplier compromise.
### Detection & Response
- **How it was discovered:** SecurityScorecard assessed the security posture of these firms, gathering non-intrusive data to grade their resilience (A-F).
- **Response actions taken:** Report recommendations suggest remediation efforts focusing on specific weaknesses rather than reporting on specific company responses to discovered incidents.
## Attack Methodology
- **Initial Access:** Exploitation of third-party and fourth-party vendor security weaknesses (Supply Chain Attack).
- **Persistence:** Not detailed.
- **Privilege Escalation:** Not detailed.
- **Defense Evasion:** Not detailed, implied weakness in third-party vendor security allowed access.
- **Credential Access:** Not detailed.
- **Discovery:** Not detailed, though poor security posture (low grades) suggests general vulnerability scanning or known weaknesses were exploited.
- **Lateral Movement:** Via supply chain relationships.
- **Collection:** Not detailed.
- **Exfiltration:** Not detailed.
- **Impact:** Successful compromise of the primary financial firm's environment via a trusted partner.
## Impact Assessment
- **Financial:** No specific costs reported; however, the context highlights the impending regulatory impact of the DORA act (January 17, 2025). Companies rated C or below (33% of financial firms) are at high risk.
- **Data Breach:** 100% compliance failure regarding supplier security assurance over the past year, affecting all major firms.
- **Operational:** Implied disruption due to widespread breaches, though operational specifics are unstated.
- ***Reputational:** High risk inherent in being linked to widespread supplier breaches.
## Indicators of Compromise
- **Network indicators:** (None specifically identified in the text, focus is on posture measurement.)
- **File indicators:** (None identified.)
- **Behavioral indicators:** Poor cybersecurity resilience grade (C or lower) indicating significant unaddressed weaknesses. Specific vulnerabilities include DNS misconfigurations.
## Response Actions
Containment, Eradication, and Recovery details were not reported for specific incidents; rather, the industry-wide *recommended* actions were provided:
- **Containment measures:** (Not specified for past incidents.)
- **Eradication steps:** (Not specified for past incidents.)
- **Recovery actions:** Improving Third-Party Risk Management (TPRM) maturity.
## Lessons Learned
- **Key takeaways:** Third-party and fourth-party ecosystems represent the most significant current avenue of attack for major European financial institutions.
- **What could have been done better:** Companies should have prioritized addressing vendor risk management, as evidenced by low security grades (33% rated C or below). Companies with A grades were 13.8 times less likely to breach than F-rated companies.
## Recommendations
- Immediately focus on improving overall security posture by eliminating **DNS misconfigurations**.
- Strengthen the security of all **endpoints** (laptops, desktops, mobile, BYOD).
- Establish a **consistent and timely patching cadence** for all assets.
- Prioritize **Third-Party Risk Management (TPRM)** to safeguard the digital ecosystem, especially in light of the impending DORA regulation.
