Domain download abuse

Posted on January 1st, 2012 in Domain News by dglosser

We just checked some server statistics… Started fresh for 2012…  How is it possible for 17.51 MB of files to be downloaded in 2012 and the day isn’t over yet???

Unfortunately, we are forced to continue to ban IP addresses which for whatever reason continue to abuse our download servers.

Hosting costs money. Please contribute whatever you can.

Immortal Domains

Posted on November 14th, 2011 in Domain News,immortal,New Domains by dglosser

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
