A new Valimail report shows that threat actors are distributing a staggering 3.4 billion inauthentic emails every single day, representing 1.2% of all email. This is happening even though 80% of all inboxes across the globe use the Domain-based Message Authentication, Reporting and Conformance (DMARC) open standard in order to detect and block fake emails.
DMARC adoption is rising rapidly. In the beginning of 2019, 140,000 domains had DMARC records, and by May this number had increased to 740,000. However, the use of DMARC doesn’t necessarily mean that the standard is fully implemented. In fact, DMARC enforcement levels are far lower across many industries, with only the US federal government and a few other sectors having an adoption rate that exceeds 20%.
