DMARC Spoof Detection, South Africa

Ten most active networks sourcing DMARC failures from South Africa:

Telkom_Internet_Broadband_105_184 and DAVO-LOOP together account for 30% of failure volume from this country. Distribution across many networks is consistent with commodity spoofing infrastructure operating from this geography.

Peak activity was observed in the week of August 3, 2026 with 8 failures recorded. Activity in the most recent 30-day window declined sharply compared with the prior period (4 vs 12 failures).

Country-level patterns don't imply that mail from South Africa is inherently malicious. Many failures reflect misconfigured legitimate senders, forwarded messages that break authentication, or automated infrastructure operating without authorization. Domain owners investigating a specific failure should look at the source IP and network details rather than the country alone. Our DMARC guide explains how to interpret these signals in your own reports.
