Ok I've run moosoft and it found nothing.
Good. Did you UPDATE it before running it? Just checking.
Look all I want to know is are there simple programs that can get passwords for yahoo accounts. No I don't want to use it I want to know how to stop it. We ended up closing the account that was being changed and we forwarded all the mail to an account we setup for her on yahoo. Well within that next hour we believe that person got into the new account as we couldn't log back in. We even wrote down the password when setting up the account. I've been doing this for awhile now but my no means am I an "expert" at a computer but I do know more than the average person. I know when someonething is up. Last night we learned that similar things have been happening since August of '01 thoughout different people on thier webforum community. Again this is a community for parents in their 20's.
The password scanners would normally have to be run off your computer, or a computer that has hacked Yahoo! (the later is not likely). Yes you can get a password scanner. If someone has compromised your computer, it is possible for them to scan for all of your passwords. More likely they would have installed a keystroke logger, and then it is a very simple process of reading whatever you have typed on your computer (passwords, email, chat, websites visited, credit card information, personal information, etc.). Once again keystroke loggers are hard to detect (software type). The hardware type are easier to spot. Generally they will be attached at the back of the computer where the keyboard attaches to the back of the computer. Some hardware keystroke loggers are placed inside the keyboard itself. This would require taking apart the keyboard. If you suspect a Keyboard keystroke logger it might be better to just buy a new one (I like the $6-$12 Chicony - internet board), if you don't know what to look for. Keyboard keystroke loggers are getting smaller and smaller. But a hardware keystroke logger would have to be installed on your fiances system.... either while she was at work, or not home, or in bed asleep, etc..
I meant "looking over your shoulder" as a figure of speach..... not litterally.
Have you tried opening up other free email accounts? Try opening up accounts at MAIL.com. See if you have the same type of problems. However....keep in mind that if you have a keystroke logger on your system... the person can read these correspondence if you are typing from the compromised computer. You may want to do your research from a different system. Otherwise they could lay low for awhile to throw you off. Further... you can try opening up other email accounts from a different computer, and see if you still experience the problems (from same location). I know you are going to get mad at me for saying this..... but most of the time errors like what you describe are user error with regard to CAPS on, faulty keyboards, bad memories, etc..... when entering passwords. I am not saying this is the case.... you may in fact have someone/something on your computer.
Also... are your passwords used for the email also being used for YAHOO chat identities? Are you using a webcam or voice communications while chatting? A Java dump can reveal IP's etc., to all those involved in voice communications logged into certain sites. This can allow someone to NUKE you, or force you off the net. You would know this were happening if you were suddenly disconnected from the net. Repeatedly. Again.... this is probably unlikely. It WOULD give the intruder enough information to begin a hack on you though.
You may want to try some other things. Like using a different computer from the same home.... and see if you experience the same problems. Once again.... do you live in an apartment or duplex? A naughty neighbor may be playing games with you... if they have tapped into your internet line. What type of internet service do you have? Dial up, Cable, DSL, wireless, networked?
The lady in England is sending me the e-mail that was sent to her mother with headers just for my investigation purposes. I am not taking this lightly. I do know that "I" convinced this is the same person who we reported to the State of Conn. Education Department and this is not a funny situation for me nor my fiance. I will prosecute once I get proof of who this is but at this point getting the proof is the problem.
Keep in mind.... that many ISP will not investigate.... if they suspect that the culprit has used many different servers, or has emailed through someone elses system. It is common for folks to send virus's without ever knowing it..... with no malicious intent for instance. It does not hurt to report offenders though. It is also possible to send emails that appear to be from someone else.
If you are really serious about protecting yourself.... I would change all my passwords from a CLEAN off premise system. Off premise in a trusted environment. Keep the suspicious computer offline until you locate and eliminate any threat. What kind of firewall do you have? Hardware or software? "Zone Alarm" (software firewall), will allow you to see what try's to access the net from your computer..... giving you the oportunity to block its access.... as well as in some cases revealing the program that is residing on your computer trying to get out. You can also have your computer and its ports scanned by going to "sheildsup" on the internet. They have a scan utility that will scan your computer over the net for you.... and give you the results. This might help to see if you have any ports open.
If someone was figuring out my passwords.... I would first off suspect a key logger or trojan on my computer, OR on my network. I would IMMEDIATELY take my system offline. I would keep it offline until I found out I was clean without a doubt. I would use several different scanners to try to weed out the trojan. I would replace my keyboard if I did not know what to look for. I would also look at my computer and see if there is anything there that should not be (hardware keystroke logger), I would scan for a software keystroke logger. There are specific ways to find the software keystroke loggers. They can be difficult to find.
Keep in mind that if there is a keystroke logger on the system..... someone will still have to view this information. If not from your computer or network... then from a trojan over the net.
If I was not able to locate a trojan or find a keystroke logger, and I still "felt" unsure... I would replace the computer.... or install a new hard drive and recreate a safe system, after I was sure that my network was clean.
Normally the only way a person could do what you think they are doing.... is to send you an email with an attachement that included a trojan. Or give you a download or removable disk that had the trojan software on it. You would then unknowingly open the file or execute/install the trojan software. This would allow them to access your computer to install a software Keystroke logger, password scanners, et.. A diligent scan with several trojan scanners will normally catch these trojans. Make sure you have the "OPTIONS" set up correctly when using the trojan scanners.... and MOST importantly... make sure that after you download the trojan scanners YOU UPDATE them before running.
Anyway..... I have lots of questions.
Be very sure that you are not at fault. User error is sometimes the only problem. Make sure your keyboard is not screwing up when you are typing the passwords. How old is the keyboard? Have you checked the keyboard to be sure it is performing properly? Accessing the email accounts from a different location would also help to narrow down the problem. If you are able to access the email accounts from a different location for instance, that would mean your problem could be your keyboard malfunctioning. Is it wireless, and if so are the batteries needing replaced? Have you created an email account at Yahoo!, and tried to access that email account from a different location? Does the password not work from the other locations as well?
Let us know what you find out.
Oh.... also... what operating system are you running... and have you made sure to update with the latest critical updates/security patches?
