Financial Industry Regulatory Authority (FINRA) has issued an information notice to brokerage firms regarding an ongoing phishing attack. FINRA is a not-for-profit organization which regulates exchange markets and member brokerage firms. A number of brokerage firms have already received suspicious looking e-mails camouflage to appear as being received from a legitimate credit union entity. The e-mail 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.
