[Ham-Computers] Email security question

[Hsu, Aaron (NBC Universal)]

Brian,

>>> Can Yahoo or whomever  trace something to that nature

First, have the owner of the account change the password, if not already done!  Then, you can attempt to contact Yahoo to see if they can get the login logs for the account.  Most likely, if the account is a "free" account, they'll say "No", or it's not possible.  Yahoo and most providers do keep logs of all logins, but the information is confidential and might require legal means to access.  If it is a paid account and you explain the situation, they might be more forthcomming with info.  Otherwise, good luck.


>>> or would the computer's harddrive keep a record of when that email was last logged onto

The computer that was used to connect to Yahoo might have an updated cookie with the login time and date, but it might not be useful as the cookie might be updated often while using Yahoo and can't be used as a reliable indicator.  The browser's history will show when a particular page was last visited (limited by the tombstone date of the history), but this also might not be reliable.  Otherwise, as Yahoo's mail is browser based, there's nothing else the browser has or kept that would be of help.

73 and good luck,

Subject: [Ham-Computers] Email security question 

I hope someone can give me some good info on the above subject.

For example, if someone has Web based email, such as Yahoo mail, Hotmail, etc. and they suspect someone has figured their password out, and logged in from another computer somewhere other than their home computer,

Can Yahoo or whomever  trace something to that nature, or would the computer's harddrive keep a record of when that email was last logged onto...Time, date, etc

I hope this is worded correctly and I didn't confuse anyone.

Thanks for any input you might can add, or suggestions.

73/Brian
