TL;DR: Financial institutions faced 566 breaches and more than 254 million leaked records by December 2022, while ransomware attacks in the sector rose from 55% in 2022 to 64% in 2023, according to SentinelOne’s analysis. The practical lesson is that resilience now depends on identity controls, segmentation, and recovery discipline, not perimeter assumptions alone.
Editorial analysis by NHI Mgmt Group, based on content published by SentinelOne: “Cyber Security in Banking. Why Cyber Attacks on Financial Institutions are on the rise”.
By the numbers:
- As of December 2022, finance and insurance organizations globally experienced 566 breaches.
- Those breaches led to over 254 million leaked records.
- Ransomware attacks on financial services increased from 55% in 2022 to 64% in 2023.
Key questions
Q: Where do financial-sector cyber defenses fail when attackers steal valid credentials?
A: They fail when identity is treated as authentication only.
Q: Why do least privilege and supervision matter so much in regulated financial services?
A: Least privilege limits how far a compromised or misused account can move, while supervision makes abnormal activity visible and attributable.
Q: What are the signs that a recovery program is not ready for a ransomware event?
A: A recovery program is not ready when teams have not practiced the runbook, roles are unclear, and approval delays slow action during a crisis.
Practitioner guidance
- Implement least privilege for all financial-sector access paths Constrain user, admin, and third-party access so compromise does not automatically expose critical systems or sensitive data.
- Segment critical systems from general user and vendor access Separate payment, transaction, identity, and recovery environments so lateral movement cannot move freely across trust zones.
- Remove default and unnecessary accounts before production use Audit inherited access, disable unused defaults, and ensure privileged accounts are explicitly justified and monitored.
Bottom line: Financial-sector breaches are not just an exposure problem, they are a resilience problem when access scope and recovery paths are weak.

Identity governance is now a resilience control in financial services. The article shows that authentication alone is insufficient when phishing, third-party access, and role overreach can all turn into business disruption. Financial institutions need authorization discipline that limits what a compromised identity can do, not just stronger password barriers. Practitioners should treat identity scope as a resilience boundary.
A question worth separating out:
Q: How should banks balance prevention, containment, and recovery in cyber resilience planning?
A: They should treat them as linked controls rather than competing priorities. Prevention reduces exposure, containment limits spread when prevention fails, and recovery restores operations after impact. The right balance is the one that still preserves business continuity when an attacker gets through.
