The National Security Agency (NSA) has teamed up with the FBI and the U.S. Department of State to release a Cybersecurity Advisory (CSA) warning about North Korean actors exploiting weak DMARC security policies to carry out spearphishing efforts. These techniques allow emails to appear to be from legitimate journalists, academics, or experts in East Asian affairs. The goal is to collect intelligence on geopolitical events and adversary foreign policy strategies. The report includes background on North Korea's cyber program, examples of past information-gathering, and measures to counter their tactics. For more information, you can read the full report on the NSA website.
