- Hello there,
-
- I am what most people would consider a newbie. However, I discovered
- a little something about Hotmail just now, thought you might be
- interested. To get this to work, you must a) have somebody's hotmail
- account name and password; b) the person must have set up hotmail's
- POP mail options to recieve POP mail in Hotmail. By downloading the
- link that says "POP Mail" just next to the "Check for New Hotmail"
- link in the inbox, it is possible to view the person's ISP login name,
- and cleartext ISP password. Here is what I downloaded tonight (I will
- comment important stuff in brackets (), although you will probably
- already know anyways):
-
- 1st POP Account: </b></td></tr>
- <tr><td align="right">POP Server Name:</td>
- <td align="left"><input type="text" name="sname0"
- value="232.182.98.45" (ISP IP address or domain name) size=30
- maxlength=36></td></tr>
- <tr><td align="right">POP User Name:</td>
- <td align="left"><input type="text" name="uname0"
- value="los_alamos"(login name, I changed it of course) size=30
- maxlength=36></td></tr>
- <tr><td align="right">POP User Password:</td>
- <td align="left"><input type="password" name="upasswd0" value="luther"
- (unencrypted password, changed again, of course) size=30
- maxlength=36></td></tr>
-
- Although this is not a HUGE vulnerablility (you need an account, and
- the account must have POP mail set up), this seems like a fairly easy
- way to get the login name and password for an ISP...from there, it
- shouldn't be too hard to find the dial up number, using social
- engineering or something. If you already knew about this, I'm sorry
- for bothering you with it. Oh yea, is there any way to get
- Java/Javascript into Hotmail messages? They filter the headers and
- such now, at least from what I've tried.
-
- Thank you for your time,
-
- Jon Robson
