Immortal Domains
We just finished recertification of 237 long-lived, “immortal” malware domains.
These are domains which continue to actively serve malware for months if not years.
Some of these domains have been active here for more than two years.
Of those 237 domains, 34, or less than 15% were removed.
That means that over 85% of these long-lived domains are truly “bulletproof”, and have remained actively malicious for over two years.
The list of those few removed domains is here: removed-domains-20111112.txt
List of these “immortals” is here: immortal_domains.txt
