themafia.us, hosted on Yahoo! is kindly serving up 2 txt files of email addresses and a virus. The mail that tries to get the gullible looks like <div align="center"> <p align="left"> <p align="left"><font color="#FF0000" size="2" face="Verdana">You have just received a virtual greeting from a friend!</font></p> <p align="left"><font color="#FFFFFF" size="2" face="Verdana">.</font></p> <p align="left"><font color="#FF0000" size="2" face="Verdana">You can pick up your postcard at the following web address:</font></p> <p align="left"><font color="#FFFFFF" size="2" face="Verdana">.</font></p> <p align="left"><font size="3" face="Verdana"><A href="http://themafia.us/a0190313376667.gif.exe" target=_blank><strong>http://www.postcards4u.com/?a0190313376667</strong></A></font></p> <p align="left"><font color="#FFFFFF" size="2" face="Verdana">.</font></p> <p align="left"><font color="#FF0000" size="2" face="Verdana">If you can&apst click on the web I've emailed Yahoo!s abuse department, but I don't have much faith in them. SURBL and URIBL both list the domain, but you may wish to configure web proxies etc to not allow the URL.
