CISA, NSA, FBI, and MS-ISAC Release Phishing Prevention Guide

The CISA, NSA, FBI, and MS-ISAC released a joint guide, Phishing Guidance: Stopping the Attack Cycle at Phase One. The joint guide outlines phishing techniques malicious actors commonly use and provides guidance for both network defenders and software manufacturers to reduce the impact of phishing techniques used in obtaining credentials and deploying malware.

CISA and its partners encourage network defenders and software manufacturers to implement the recommendations in the guide to reduce the frequency and impact of phishing incidents. For more information, see CISA’s Malware, Phishing, and Ransomware and Security-by-Design and -Default webpages.
