A Guide for Bank Leaders to Strengthen Cyber Resilience against AI-Threats

As banks rapidly adopt artificial intelligence and cloud-native architectures, the banking cyber threat landscape is shifting at an unprecedented pace. Adversaries are leveraging AI-empowered botnets, exploiting software vulnerabilities and identity gaps, and launching sophisticated generative AI attacks designed to bypass traditional perimeter controls.

Institutions that combine traditional threat intelligence with AI governance, automated detection, and proactive security operations will be better positioned to defend against increasingly sophisticated cyber threats. The most effective programs treat AI as both a business enabler and a new attack surface requiring dedicated security oversight.

To help bank leadership, CISOs, and risk executives navigate these emerging challenges, we have curated an essential set of cybersecurity and AI governance resources—and broken down how to leverage them both strategically at the board level and operationally on the front lines.

4. Recommendations and Resources for Financial Institutions: Enhanced Resiliency and Recovery 

ABA, in collaboration with the Financial Services Information Sharing and Analysis Center (FS-ISAC), and the U.S. Department of the Treasury’s Office of Cybersecurity and Critical Infrastructure Protection, released a new resource–Recommendations and Resources for Financial Institutions: Enhanced Resiliency and Recovery–to help financial institutions strengthen resilience before, during, and after significant events to include cyberattacks, technology outages, natural disasters and man-made incidents.

This resource emphasizes the importance of building trusted relationships, testing response plans, establishing clear communication channels, and understanding available public- and private-sector support before a crisis occurs. It includes state-specific appendices designed to help institutions quickly identify state-level points of contact and relevant partners, including emergency management agencies, banking regulators, fusion centers, Cybersecurity and Infrastructure Security Agency (CISA) regional personnel, federal law enforcement partners, state bankers associations, and other public- and private-sector resources that can support coordination, information sharing, incident response, and recovery.

Applying These Resources: Strategic vs. Operational Impact

Operationalizing Defense: The Mid-Year Check-In

Frameworks like NIST and CRI provide blueprints, but operational resilience requires continuous audit and execution. 

The Register.Bank Mid-Year Security Checklist provides security teams with an immediate roadmap to eliminate common attack vectors before year-end:

• Email Authentication Hardening: Moving DMARC policies to `p=reject`, enforcing MTA-STS, and auditing third-party senders using 2048-bit DKIM keys to stop Business Email Compromise (BEC).
• TLS Certificate Automation: Preparing for shorter certificate lifecycles with automated ACME workflows and DNS-based validation.
• Identity & Access Controls: Removing SMS-based MFA in favor of phishing-resistant passkeys and verifying SOC 2 / ISO 27001 certifications across registrar partners.

Executing these technical checks lays the groundwork for the most impactful step a bank can take: securing its digital identity.

Cyber Defense: .Bank is Essential for Your Digital Identity

While frameworks, AI monitoring tools, and incident response reports provide vital defense layers, banks must also secure their foundational digital identity.

Phishing, brand spoofing, and domain imposter attacks remain among the most prevalent entry points for financial cybercrime—intertwined with rising identity and credential compromise. Implementing .Bank directly addresses a critical subset of this risk through stronger domain and email authentication controls making .Bank, The Domain for Banking a vital cybersecurity control tool. 

How .Bank Protects Your Bank

Unlike open top-level domains (TLDs) like .com or .org—where anyone can register a look alike domain for phishing campaigns—.Bank is an exclusive, verified digital identity reserved strictly for eligible banks.

Switching to .Bank automatically upgrades your bank with these foundational safeguards: 

1. Mandatory Security Requirements: Every .Bank domain enforces built-in security controls, including strict DNSSEC (DNS Security Extensions) to prevent DNS hijacking, robust DMARC/SPF email authentication to eliminate email spoofing, and mandatory multi-factor authentication (MFA) for domain management.
2. Mitigation of Executive & Customer Spoofing: Because threat actors cannot easily register a .Bank domain, email spoofing attacks attempting to impersonate a legitimate .Bank domain are significantly reduced. The strict verification controls provide a robust defense that substantially lowers the risk of domain-based impersonation. 
3. Customer Trust & Brand Protection: Moving your primary web presence and email to .Bank gives customers and partners immediate visual verification that every communication is authentic and secure.

Secure Your .Bank Digital Identity Today

Cyber resilience requires a comprehensive approach—combining modern AI governance, active threat intelligence, and uncompromised digital identity verification. By implementing industry-backed guidelines from CRI and NIST alongside the domain security of .Bank, your bank can significantly reduce its threat surface.
