Repeated from my work blog. According to a thread today in the Skype Windows Forum, skype users (and that includes me) have been receiving bogus skype chat messages which ask users to click on a link. If you do so you apparently get a rootkit which is only recognized by the very latest virus software versions.
In my case the chat message allegedly came from a friend and had a vaguely plausible subject, however it was clearly not genuine becuase the link was odd and becuase the user immediately left the chat session after sending the link. An example that I received this morning is:
[10:05:37] XXXX says:
Check up this: http://24243.psadionkderunhdetionkdase.com/7/7849
[10:05:40] XXXX left this chat
Needless to say you should not even think about following the link which downloads either an .exe or .pif file that presumably includes the rootkit.
