The Financial Threat Landscape: Why Attackers Target the Vault

Most breaches begin with social engineering, then pivot through misconfigurations or overprivileged accounts. We have seen MFA prompt bombing, token theft, and lateral movement through neglected servers. Prevention demands layered defenses, continuous monitoring, and the humility to assume breach at all times.

People First: Building a Human Firewall in Finance

Hardware security keys, passkeys, and sign-in policies that reject weak factors blunt credential attacks. Pair them with realistic simulations, teaching staff to spot invoice fraud, QR phishing, and deepfake voice requests. Reward quick reporting, not just perfect scores.

People First: Building a Human Firewall in Finance

Run executive tabletop drills for ransomware, core banking outages, or payment rail compromises. Include legal, communications, regulators, and customer care. After-action reviews should refine playbooks and contacts. Share your tabletop lesson learned for our next newsletter feature.

A branch teller noticed a nervous customer following a script over the phone, supposedly with a bank supervisor. The teller paused the transaction, used official callbacks, and uncovered a live social engineering attempt. Dignity, patience, and policy saved the day.

Threat Intelligence and Real-Time Detection

Integrate feeds from trusted sources and industry sharing groups, applying STIX and TAXII to normalize indicators. Prioritize relevance to your assets. Automate enrichment in your SOC so analysts focus on decisions, not copying indicators between tools.

Threat Intelligence and Real-Time Detection

UEBA can flag unusual logins, privilege escalations, or transfers outside typical patterns. Blend security and fraud signals: device reputation, velocity, counterparties, and geolocation. When confidence is high, auto-hold suspicious transfers and require out-of-band verification.

Secure by Design: Cloud, APIs, and Payments

Enforce strong client authentication with mutual TLS and OAuth profiles designed for finance. Validate schemas, throttle requests, and inspect payloads for abuse. Maintain a living inventory of APIs so nothing critical hides outside monitoring and testing.

Third-Party and Supply Chain Risk

Automate vendor monitoring for breached credentials, exposed buckets, and policy gaps. Map vendors to business processes and data sensitivity. Require timely remediation and test incident handoffs. Share your must-have clauses for vendor contracts in the comments.

Incident Response and Resilience That Earns Trust

Ransomware-Ready Playbooks

Maintain offline, immutable backups with tested restore times. Segment admin credentials, restrict scripts, and monitor unusual file operations. Your playbooks should include legal, regulators, and customer care. Invite your crisis team to subscribe for monthly scenario drills.
