ALERT: microsoft-key.com, 91.217.153.17

microsoft-key.com was registered through the well known criminal friendly, BIZCN on October 7th (key-microsoft.com existed previously, same IP range), and not surprisingly, is up to no good. The domain is presently only in German for some reason (auto-redirs to /de-DE/, and no other language dirs seem to exist).

A translation via Google, since I don't speak German, shows;

Quite why it's only targeting German speaking individuals is puzzling, but I suspect it's likely only a matter of time before it's active in other languages (already working on takedown of course, and have notified MSRT).

The IP it's living at will come as no surprise either;

IP: 91.217.153.17
IP PTR: Resolution failed
ASN: 41390 91.217.153.0/24 RN-DATA-LV RN Data, SIA

The entire range has and continues to be, a haven for criminals and malicious activity, with malware and phishing present on virtually every IP. Personally I'd strongly urge you blackhole it if you've not already.
