Google Online Security team today announced of "adding distribution domains to the set of information the company send to network administrators registered through the Safe Browsing Alerts for Network Administrators service when its automated tools find phishing URLs or compromised sites that lead to malware on their networks."
"These are domains that are responsible for launching exploits and serving malware. Unlike compromised sites, which are often run by innocent webmasters, distribution domains are set up with the primary purpose of serving malicious content," the team said.
These notifications provide administrators with important information to help them improve the security of their networks.
Those new, “Google Safe Browsing Alerts for Network Administrators -- an experimental tool which allows Autonomous System (AS) owners to receive early notifications for malicious content found on their networks.
A single network or ISP can host hundreds or thousands of different websites. Although network administrators may not be responsible for running the websites themselves, they have an interest in the quality of the content being hosted on their networks."
If you're a network administrator and haven't yet registered your Autonomous System (AS), you can do here.
