Ten most active networks sourcing DMARC failures from Taiwan:

HINET-NET and Google together account for 49% 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 July 20, 2026 with 1 failures recorded. Activity in the most recent 30-day window held roughly steady compared with the prior period (0 vs 0 failures).

Country-level patterns don't imply that mail from Taiwan 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.
