Spam Propagation Findings

Ingrid

⇤ Compromised Systems Findings

Spam Propagation is composed of compromised systems sending unsolicited commercial and/or bulk email.

If a company offers a bulk email sending service, such as a digital marketing company that sends marketing material on behalf of their customers, they are excluded from the Spam Propagation risk vector. These companies are identified with an envelope icon next to their name on their company overview.

To protect our data sources, destination mail server information or destination IP addresses are not provided. Use the source IP address and IP block ranges in your infrastructure as a compass to narrow your search for spambots. Spambot activity in the source IP address may not be the same IP address of your company mail servers.
