FINRA Warns of Fraudulent Phishing Emails Targeting Member Firms

FINRA warns member firms to be on the lookout for a fraudulent phishing email that is currently circulating. Brokerage firms reported to FINRA that they have received suspicious emails targeting their compliance personnel. The email appears to be from a legitimate credit union attempting to notify the firm about potential money laundering involving a purported client of the firm. The email directs the recipient to open an attached document—which likely contains a malicious virus or malware designed to obtain unauthorized access to the recipient’s computer network. As a reminder, phishing scams are ever-changing and are designed to infiltrate the computer network of the recipient. Use caution when opening emails from unknown senders and do not open attachments until you verify the sender and information that might be included in the document.

FINRA Report on Cybersecurity Practices

This report continues FINRA’s efforts to share information that can help broker-dealer firms further develop their cybersecurity programs. Firms routinely identify cybersecurity as one of their primary operational risks. Similarly, FINRA continues to see problematic cybersecurity practices in its examination and risk monitoring program. This report presents FINRA’s observations regarding effective practices that firms have implemented to address selected cybersecurity risks while recognizing that there is no one-size-fits-all approach to cybersecurity. 

When selecting the topics for this report, FINRA considered the evolving cybersecurity threat landscape, firms’ primary challenges and the most frequent cybersecurity findings from our firm examination program. First, we address how firms have strengthened their cybersecurity controls in branch offices, which is especially important for firms with decentralized business models. Second, we discuss limiting phishing attacks, which remain a top cybersecurity challenge for many firms. Third, we explain the importance of identifying and mitigating insider threats, which are of concern for many firms. Fourth, we describe the elements of a strong penetration testing program. Finally, we share observations regarding establishing and maintaining controls on mobile devices, which have emerged as a significant risk for many firms because of their increasingly widespread use by employees and customers.
