Explaination: A person could gain useful info. about VICTIM () hotmail com that could be used in password recovery... even by a unlegimate user by simply "getting a LEGIMATE reply" from VICTIM () hotmail com ;o) Strange! Firstly, the simple trick is to make him/her [whome_he_wanna_hack () hotmail com] just reply you... WITH ANYTHING! [Maybe... BY ASKING FOR SOMETHING ...Indeed painless!] As soon as the attacker get's a email reply from VICTIM () hotmail com, the attacker then simply look's at the email header, & fInd's VICTIM () hotmail com country's gmt time: through his email header [ ... which was used by "VICTIM () hotmail com" while regestering HOTMAIL!] A TIPICAL HEADER WOULD LOOK LIKE ---------------------------------- X-Originating-IP: [*.*.*.*] X-Originating-Email: [VICTIM () hotmail com] Received: from *.*.*.*by lw10fd.law10.hotmail.msn.com with HTTP;Wed, 13 Aug 2003 13:40:38 +5:45 GMT ---------------------------------- Using his grade 3 maths skills, (o: the attacker could then effectively predict the victims's country/STATE name [ ... which was used by the "victim" while regestering HOTMAIL!] just by knowing his +/- **:** GMT through the email header! of VICTIM () hotmail com This info. could be very effectively used in Password recovery policy of hotmail! Well, after about 40% of the holygrain OBTAINED! ........ All the attacker now have to do is guess a simple/'SENSIBLE' secret answer [most of the time...] before he get's full control of VICTIM () hotmail com INBOX! ________________________________________________________ Microsoft REPLIED me, pointing out ... about a SUPPOSE TO BE similar issue! [quote] ->3'rd para. LAST LINE! http://www.informationweek.com/story/showArticle.jhtml?articleID=10817862 If the attacker knew the victim's E-mail address and basic geographic location information, accounts would be at risk, the advisory stated. [/quote] [quote] -> 4'th para. The vulnerability appears to be minor, says John Pescatore, research director at Gartner. The fact that an attacker would have to enter city, state, and ZIP code information to exploit the security hole would have prevented widespread automated identity theft, he says. "It would generally prevent automated attacks and at least require me to know two pieces of data about a target E-mail account," he says. [/quote] well i read the issue! but MARK THAT, ....... i submitted you a technique to predict the country/state by which it could pe predicted!!! ... Isn't the word... "MAY BE.. if" and "this is how..." different??? ___________________________________________ wHAT DO YOU SAY, guys? __________________________________ Do you Yahoo!? Protect your identity with Yahoo!
