TL;DR: Financial firms are attacked up to 300x more often than other industries, ransomware spiked 900% during COVID-19, and valid corporate credentials now outvalue stolen cards because attackers increasingly live off the land, according to KnowBe4. The sector’s real problem is not volume alone but the combination of human-risk exposure, third-party entry points, and AI-amplified social engineering.
Editorial analysis by NHI Mgmt Group, based on content published by Knowbe4: “Financial Sector Cyber Threats: The Shifting Landscape”.
By the numbers:
- Financial firms are attacked up to 300x more often than other industries.
- Ransomware alone spiked 900% in a matter of months during COVID-19.
Key questions
Q: What breaks when banks treat valid credentials as proof of trust?
A: When banks equate valid credentials with trust, they create a blind spot for insiders and credentialed adversaries who can move normally after login.
Q: Why do AI-generated phishing and impersonation campaigns increase financial-sector risk so quickly?
A: They reduce the effort needed to create believable lures and approvals, which increases the volume and realism of attacks without increasing operator skill.
Q: What do security teams get wrong about third-party access oversight?
A: They often track vendor access as a procurement issue instead of a lifecycle control.
Practitioner guidance
- Strengthen high-risk credential monitoring Correlate login source, device posture, geolocation, and privilege use for finance, treasury, and admin accounts so valid credentials are not treated as inherently trustworthy.
- Add out-of-band verification for sensitive requests Require a separate verification path for payment changes, supplier bank detail updates, and privileged approvals when requests arrive through email, chat, or voice.
- Inventory and scope third-party identities Map every vendor, fourth-party, and service identity that can reach regulated systems, then remove standing access and enforce least privilege for each pathway.
Bottom line: Financial-sector cyber risk is shifting toward abuse of trusted credentials, vendor pathways, and AI-assisted impersonation rather than only overt malware or noisy intrusion.

Credential abuse is now the sector’s primary trust failure, not a side effect of intrusion. The article shows that attackers increasingly prize valid credentials because they are easier to operationalise than stolen payment data and harder to distinguish from normal activity. That shifts the security problem from breach detection to access legitimacy, especially where approved sessions can be reused for fraud or lateral movement. Practitioners should treat credential trust as a governed asset, not just an authentication event.
A question worth separating out:
Q: How do fraud and IAM teams work together on AI-driven abuse?
A: They should share the same decision points. Fraud teams bring anomaly detection, rate patterns, and device intelligence. IAM teams bring identity proofing, authentication policy, and step-up enforcement. When those signals are combined, the organisation can treat suspicious automation as an access decision rather than a standalone fraud alert.
