Threat Intelligence Email Blasts This Week:

North Korean Hackers Exploiting Weak DMARC Settings  The U.S. government has warned that a North Korean hacking group, known as Kimsuky, is exploiting vulnerabilities in email security protocols (DMARC settings) to conduct disguised spear-phishing attacks. These weak DMARC settings allow the hackers to send emails that appear legitimate, thereby increasing the success rate of their phishing campaigns. We have a new finding in our pen tests as well as upcoming content addressing DMARC/DKIM/SPF settings as well as some remediation guidelines in the threat intelligence email blast.
