This malicious activity, dubbed "SubdoMailing", leverages the trust associated with these domains to circulate spammy and malicious phishing emails by the Millions each day, cunningly using their credibility and stolen resources to slip past security measures..

We encourage everyone to visit the "SubdoMailing" checker website at [https://www.guard.io/subdomailing ] to ensure the security of their domains.
