2090 charsFinancial Industry Regulatory Authority Issues Cybersecurity Alert on Heightened Threats From Iranian Cyber Actors
On March 16, 2026, the Financial Industry Regulatory Authority (FINRA) issued a cybersecurity alert warning member firms of elevated risks from Iranian state-sponsored and Iran-aligned threat actors. Although FINRA is not aware of significant Iran-related cyberattacks against the financial services industry as of the alert date, it noted that Iranian threat actors are actively targeting U.S. financial institutions and critical infrastructure sectors amid ongoing geopolitical tensions in the Middle East. Iranian actors have historically demonstrated capability and intent to conduct disruptive and destructive cyber operations against U.S. organizations, particularly during periods of heightened geopolitical tension.
FINRA identified common tactics, techniques and procedures (TTPs) used by Iranian threat actors, including gaining initial access through credential compromise via password spraying, brute-force attacks, spear phishing, social engineering, and exploitation of known vulnerabilities in internet-facing systems. For persistence and expansion, actors employ multi-factor authentication (MFA) bypass techniques such as "push bombing," modify MFA registrations, harvest credentials, and target third-party service providers. Disruptive actions include ransomware deployment, destructive wiper malware, distributed denial-of-service (DDoS) attacks, and hack-and-leak operations.
FINRA recommended member firms prioritize defensive measures including vendor and third-party risk management, asset management and visibility of internet-facing systems, deployment of phishing-resistant MFA, ongoing security awareness training, vulnerability and patch management, security monitoring with retained logs, incident response planning, and maintenance of regularly tested backups. Member firms identifying data breaches should contact their Risk Monitoring Analyst and report incidents to FINRA via the Regulatory Tip Form, the Securities and Exchange Commission (SEC), the Federal Bureau of Investigation (FBI), and the Cybersecurity and Infrastructure Security Agency (CISA).
