Lenovo / Superfish fuss, I set out to identify those Superfish domains and IPs that I could, for the purposes of blocking or monitoring.
The domains and IPs that I have been able to identify are here [csv].
Superfish appear to operate the following domains (and several subdomains thereof):
These following IP addresses and ranges appear to be used exclusively by Superfish (some of their other domains are on shared infrastructure).
All of those IPs are allocated to Datapipe in the US. Superfish itself is based in Israel, which seems to be a popular place to develop adware.
Do with this data what you will, if you have any more IPs or domains then perhaps you might share them in the Comments.
