WMP Phone Home
Yes, although it has long been suspected one site has finally come up with proof (and a list of IPs) that Windows Media Player 10 ‘phones home’ – sending the identity of every single file you open to the following IPs:
1) Napster (63.241.55.113)
2) Intel Corporation, spider (147.208.188.228)
3) MUSIC MATCH (63.236.14.35)
4) Digital Telemedia, INC (209.73.26.183)
5) ezgov.com CERFnet AP2P (12.129.72.200) (12.129.72.145)
Of course the privacy threat can be eliminated simply by adding the offending IPs to the ‘restricted’ list/zone in your firewall of choice.
