Hi everyone

As of last night someone managed to hack into my Yahoo email account. I would just set a new email up but Ive used my account for several years and everything is stored in there.

I don't know what to do, and how to regain entry, also the longer its left I wonder what someone is doing with my account.

Ive emailed Yahoo but am still waiting for a reply, god I hope they can help.

Ive tried to reset/retrieve my password but the system is sure I don't know my own DETAILS!!

Im stuck for ideas, anything at all would be grateful. Thank you

Other then contacting Yahoo, you are stuck.

As Scott has told you,I don't think anything can be done.The best advice I can give is to set up another account.There are plenty of free one's on offer.Never store anything sensitive in one account.Spred it over several.Better still,dont store anything sensitive at all.I have three free accounts,one for the family,one for close friends,and one for basic junk sites,which ask you to click on a link(if your not sure it's genuine,dont do it!!)to get entry to a tech site or whatever.My emails,both sent and received are mostly boring affairs,with nothing of importance.Always use a good password,both letters,numbers and symbals,and don't forget to write it down,and keep it safe at home.If Yahoo won't help,drop them.

Has anyone tested this YahooPOPS program to see if it works?
http://yahoopops.sourceforge.net/index.php

I may try it this weekend. Apparently it allows you to download your Yahoo mail to Outlook (for example) so that you can save your mail on your local machine.

Looks interesting, but I'm not sure there is much in my Yahoo mail I want to keep.

Hi there wel I'm glad I'm not the only one as from the 2ndmay I also have been hacked and like yourself I cannot getting even with my password etc I've contacted Yahoo several times (about 90and I'm none the wiser my prob is my husband has ben getting messages via Yahoo messenger which contain porn links! My worry is who has the id now as I've a Yahoo photo album with mny kids pics in Yahoo have been told this but to close my account and delete my id I need to be sighnd in (a bit impossible when uve been hacked and your password changed,, any help would be verry gratefull of how to get back my id or close it so my Yahoo photos etc all get removed ,
Many thanks

Nicola, as mentioned above - Yahoo cannot be hacked into. Also it's unethical and nobody here would help somebody hack into anything, even if the reasons were legitimate. So I'm afraid apart from keep trying Yahoo, there is nothing that can be done.

Maybe your not up to date ,if Yahoo can't be hacked how come my hubby and others on my messenger list are getting pms from me with porn links in then . :rolleyes:

maybe ur not up to date ,if yahoo can't be hacked how come my hubby and others on my messenger list are getting pms from me with porn links in then . :rolleyes:

Yahoo Mail and YIM are two separate programs.

It could be possible that you've got a trojan/spyware on your computer. That would explain the sending of the porn links via Yahoo messenger. It might also explain why you can't get into your Yahoo account. The bit of software might have been tracking your key presses or something like that. If it can send porn links to your husband, it could reset your password or send it to someone else.

So do the following:


Get a virus scanner and make sure it is up to date. Do a full scan on your PC
Download some spyware removers (search for Ad-Aware & Spybot: Search & Destroy on http://www.download.com/)
It might also be worth getting a firewall installed. One does come with Windows XP if you are running that.
make sure you have the latest security fixes for your version of windows

Hi,
Any web based email should not be used for important stuff for storage in email. Yahoo, at some time or another, maybe every few months or so, changes its programming, offering something new.
There is a chance that any email will be lost at that time.
The chances are "slim and none" that your email can be recovered.
The safest email is from your own home computer, using Outlook or Outlook Express, with an ISP, or whoever. This type of email, with all its folders, can be backed up (copied or burned) to a CD-R, or other media; and can be re-installed into the computer. There are other ways to backup web based email as well.

Unfortunately, you are stuck. Yahoo probably willl not reply, or worse yet, will probably not be able to do anything about it.
Best wishes,
fredg

Why do you persist in giving out this misinformation, Fred? Yahoo or any service, uses redundancy, fault tolerance and real time backups. There is no way that they will lose mail when making a programming change. You have said many times that you just want to help people, well how is it helping when you give them such bad information?

Are their programs out their that people can use to hack your account?

Are their programs out their that poeple can use to hack your account?

Whether there are or not is not the issue. The issue is it is illegal to do so and therefore such questions will not be dealt with kindly here.

Can only happen if it all gets fried, simple as that... the possibility of them losing it while changing or upgrading, is zero.

Just a short reply.I found this while scanning articles on Computeractive magazine.The link takes you to an artcle about web security,including email.

Number one you probably won't never get it back because if they hacked it they know all the tricks in the book number two you should protect yourself more crackers cannot crack passwords such as this ~!@#$%^(space)for(space)serious(space)^%$#@!~ number 3 you can get a cracker from many different websites but I doubt it will work sorry hun make a new one and make your password more difficult spaces numbers symbols they can't crack that on Yahoo there is no way

Hey guys,
I'm sorry but I think someone is trying to hack my email. I received an email message that I'm 98% sure is a hoax to get my password. I need some feedback on what someone else thinks...
So, I got this feeling because it seemed like a very odd email...
Here's why:
It's titled: Yahoo!: Please Verify Your Email Address
(very official Yahoo! Message BUT)
It says:
Your Yahoo! ID: minerchic2004 (that's NOT my Yahoo! ID)
Your Email Address: [email protected]
(HOTMAIL?? -that's what I first noticed to be odd... why does Yahoo! Want to verify my HOTMAIL email to a Yahoo! ID I don't even have or know? I don't understand!! )
... then there is a link and when I click on it, it asks me for my password (again, very official Yahoo! Site).
I've heard about exploits before (I'm not a "total" spazz) and I think this might be one... or is it someone that opened a Yahoo!Account and put my hotmail email by mistake as a secondary email address and THAT's what Yahoo! Wants to verify?
I'd LOVE to be 100% sure on this!

My first instinct was that someone tried to use an exploit meant for Yahoo! To get my Hotmail password (THAT was a spazz)... what do you guys think?

Sounds like a scam to me, also make sure you keep a firewall up, spyware remover programs and such. To be safe

If you ever get an email asking you to verify your email, beware. It's nearly always a hoax. If you have just signed up to a forum and they send you an email asking to verify, fine. But that will just be a case of clicking a link - you won't have to enter your email/password.

One good way to test if these emails are a hoax is this... Normally, the email will have a link saying click here, followed by an address that looks valid. If you right click on this link and choose Properties, it will show you the address the link is pointing to. If it's something to the link that was on the page, it's a hoax.

If you want to read a little more on this, try searching Google for the term "phishing".

can only happen if it all gets fried, simple as that......the possibility of them loosing it while changing or upgrading, is zero.

Hi,
I do know of several instances where this has actually happed with Yahoo Email. The chances are not zero that it will happen. The chances are more like "slim"; but it has happened!
It has also happened with Groups, before Yahoo changed it to Clubs instead. Ask anyone in the Crafts groups, who also lost email in other email addresses at Yahoo, not associated with any groups.

Okay. You need to SLOW DOWN.

It is highly unlikely someone broke into yahoo's systems just to grab your password. They probably got it some other way.

What you need to do is contact Yahoo and tell them what happened. As long as you are _reasonable_, they can help you.

No offense, but if you're sending them e-mails that look like your post, they probably think that they are spam. You need to use proper punctuation and employ a spell checker. Proofread. It will help a lot.

Yahoo will help you out. Ignoring this kind of thing would be very bad PR for them...

I've been using Yahoo Mail since the beginning and have never heard of an upgrade losing anyone's mail. And they are still called Groups, where does "Clubs" come form?

Fredg, might be an idea to back this up with some proof. A lot of the time, it's just speculation. This statement is bound to get a lot of people worried.

LT,

Don't hold your breath. Fred rarely, if ever, backs up what he says with proof. Most of the time its because he has no proof. He tends to make things up to make him sound more knowledgeable, but when challenged to show proof, he clams up.

I will repeat what I have said before. There is no way a company like Yahoo is going to lose stored mail in a system upgrade. There are just too many controls in place for that to happen.

I'd LOVE to be 100% sure on this!!

My first instinct was that someone tried to use an exploit ment for Yahoo! to get my Hotmail password (THAT was a spazz)...what do you guys think??

You can be 200% sure of this. No reputable firm that I have ever encountered will ask you to verify your account information except during the login process. So any such request is a scam.

Yeah... that really makes them believe you when you say Yahoo changed it from "groups" to "clubs". fredg, then tell us, why do they still call them groups? And chances are more like none to lose information, emails, etc... the possibility for it is slim to none? More like none since they have backups.

It's a program that you can get at many hacker sites. Even one that Yahoo has put up themselves called yah-hell! It makes you sound like a part of yahoos administration it is keylogged usually but not always if you open it or type anything they will have your pass, ip etc anything really and its not that hard to disable firewalls if you have them or even virus protection trust me I know! So when you get something like that your best bet would be is to go to command prompt if its through messenger and type in echo press enter and leave the window open! This little trick acts like a mirror so anything they try to do it reflects off you and goes straight back to them!

Can we get this thread locked to stop hacking discussions please?

Better to have it deleted... so no one will get any ideas.

Some things to remember:
1. Never give out YOUR password to anyone.
2. There is no such thing at a "bot" that will return a password to you.
3. Never visit password websites that end in .da.ru, tk, or other odd extensions.
4. To find a good service to help you do a Google search on "needapassword" with NO spaces.
5. Never post your email address or the email of the password you are wanting on a message board.

Good luck.

4. To find a good service to help you do a google search on "xxxxxxxxxxxxx" with NO spaces.


No "good" service will give you the password for an e-mail account. The only way to get a forgotten password is to contact the service providing the mailbox.

This "advice" will be reported and removed.

First of all Yahoo passwords can be taken in many ways. There are plenty of trojans out which steal Yahoo passwords. There are crackers made all the time which will crack a password to a Yahoo account (especially if it's a simple password, harder passwords are usually safe). There are also a lot of scams such as the email scam mentioned above or websites which look exactly like a Yahoo website and asks you to login. All of these will give someone access to all services available from Yahoo with your name (chat, Yahoo messenger, email, Yahoo 360, etc... ). Here is a decription of one and details on how to protect yourself from these types of fake logins. http://oopsweb.net/htmlfiles/fakelogin.htm

Whoever said Yahoo can't be hacked is fulla crap. Mine was just hacked last night. Fortunatly I have several ways in which to contact all the important friends on my account and now the little freak who hacked me won't be getting any satisfaction from my contact list. The told me and several of my contacts he would return my account if he got flashed.. (yes I spoke to him from another Yahoo account as he was on mine all night.

The only things I had that I'd like to get back from the SOB is my Yahoo groups. I don't know where some of you get off being all self righteous and saying that there is no program that can hack Yahoo when this forum has several people in it who were hacked.. I'm pretty sure those asking for help have been legitemetly hacked if they were out to hack Id's willy nilly they sure as hell wouldn't be posting this forum. If you know how to help them resolve their dilema why won't you help them. Frankly I think the secret needs to not only get out but to get out to Yahoo so they can write blocking programs to stop it from happening.

Well what if you report to the authorities? Couldn't they track the person doing this? Hackers can be hacked to you know.

Like others I have tried contacting yahell to and because the hacker is smart enough to go into account details and change the info therin it makes it almost impossible or maybe impossible to get back into your own accounts

The problem here is your understanding of what being "hacked" means. I don't believe that there is a program that someone can use to bypass Yahoo's security and get into someone's account. However, there are other ways for people to gain access to someone's accounts. Keyloggers, social engineering, simply guessing a password, among other methods have and will continue to be used to access a Yahoo account. The point here is that the alleged "hacker" didn't break into your Yahoo account, rather they used some method to trick you into revealing your password to them. Once they have that password, they can gain control of the account, changing password, security questions, personal info, etc.

Bottom line, is you, most likely, contributed to the loss of your Yahoo account.

First, the security questions are your birthdate and zip code. Your birthdate can easily be found. In the profile Yahoo asks you to create, it shows your age, and if the hacker can figure out the date (there are only 365 days) or find it somewhere else like if you have a personals account, they have it.

The second piece of information they use is your zip code. Again, they ask you for your city in their profile. I think it may even be there by default. If you live in a smaller city, there may be only one zip code.

The 3rd is your "security" question. Well, if you ask them nicely enough, they'll give you what the question is, and you just supply the answer, so if you put in something like they suggest, the answer could be easily guessed.

The problem is that once they get in they are allowed to change your security information and Yahoo will not look back in the records to see what it was before the problem. They won't even look back at the original information. So, once you have been hacked no matter how it has been done, Yahoo refuses to work with you to get it back, even though it is they themselves that allow your security information to be changed.

A persistent hacker and one with a little intelligence can get your Yahoo account easily.

The worst part is this is tied to everything. It is tied to any service you use on Yahoo, paid and unpaid.

djstarz, that's NOT "hacking" that's just a simple bit of Social Engineering.

Actually Yahoo did help me after over a month of emailing back and forth. I simply told them of several groups I had created in the Yahoo groups that were innaccessible except by permission and 2 of the groups had at the time of my being hacked into, no members.

Unfortunately the dumbass hacked many of my friends and once in deleted their accounts.. Made me look bad since he was such an to them when he had control of my account.

I always doubt posts like yours because I had several things going on Yahoo, a web page through geocities, a personals ad (which I had paid for on and off, unfortunately off at the time it happened), chat, email. They did nothing to help and even stopped responding to my email. I can email them now until I'm blue and they don't respond. I'm not the only one who they've done this too. They refuse to take any information from me except the "security information" which they allowed to be changed. They won't even accept the original answers.

As far as social engineering... I guess Yahoo socially engineers their accounts to be stolen...

They refuse to take any information from me except the "security information" which they allowed to be changed. They won't even accept the original answers.

As far as social engineering... I guess yahoo socially engineers their accounts to be stolen....

First on social engineering (which is the crux of this issue). Lets say you pay for the best locks on the doors of your house, but then you leave a key under the doormat. And a thief cases your home, notes someone reaching for the key and comes back later to rob the house. Is this the fault of the company that manufacturers the locks? Did the locks fail in any way? Did the lock manufacturer do anything to make it easier for someone to break into the house?

This is the essence of social engineering. Most breakins of computer networks occur because people are tricked into revealing passwords, leave passwords where they can be easily found or use passowrds that are easily guessed or broken. There is a scene from a Clear and Present Danger where CIA techs break a password in minutes by simply guessing obvious possibilities, in that case, it was the person's birthdate but backwards.

No one sets up anything to be social engineered. It's the users who make it easy to for someone to social engineer them. So blaming Yahoo for that is putting the blame in the wrong place. Sure Yahoo could add more levels of security, but that would make it more cumbersome to log in and use the service, which would make people go elsewhere. Or they could add additional security but at a fee.

So Yahoo didn't "allow" anything to be changed. Once someone lets someone into their account they are letting them change things.

That all being said. I do fault Yahoo for not helping the user regain control. I had a situation with a pay service, where my account was compromised. This was done through no fault of my own, but a lapse on the service that allowed someone into the account information database. I had to go through a few layers of security and fax copies of credit card statements showing my paying for the service, but eventually the account was recovered.

This is part of one of the problems with services like Yahoo. Anyone can setup an account with little ort no verification of data. If some verification was required, it would make it easier to recover compromised accounts.

Of course it didn't help. In response to your letting Yahoo off the hook, while it can be agreed you get what you pay for, if Yahoo pretends to have security, but doesn't, it IS their fault.

In this case, Yahoo does several things that allow for this so-called social engineering. First, part of the security information is your birthdate, then they ask you to fill in your profile which they include your age. Part of the security information. Duh. Then they ask for your city. Well, if they're using your zip code for "security" the "hackers" only need to guess 1 or at least a limited amount of information.

As far as helping you get back your account. Help? They refuse. If you don't have the CURRENT zip code forget it. They get ruder and ruder as you beg them. I gave them IP address information. I even had a static IP at one of the computers I logged in from. I gave them IP range history. I pointed out to them that in their own email that they sent me information me my password had been changed they included an IP address that belonged to an ISP in California. I gave them the ORIGINAL security information and was willing to provide any additional information. They absolutely refused. They acted like I was trying to steal the account. They were rude and after a while, would not even answer my email.

Obviously Yahoo does have some security, they don't just "pretend" it. How adequate that security is open to interpretation. The security question is only used if you forget your password. If you know the password you can easily change the security info. Very few services I know have anything more. AOL, for example, offer a SecurID for a fee. This generates a random number every minute or so that is synchronized with your account.

Like I said, I fault Yahoo for not helping furthewr, but then I don't know their side of the story. Maybe you are the one trying to get into someone else's account.

My point here is that you have ragged Yahoo for some things that I don't believe are their fault. So I'm defending those points.

Hi
Am new to this site,oh, by the way nice site!
My Yahoo account is not hacked that I know of,but I am locked out of it for 12 hours or so,which Yahoo told me how this is done.It's real easy.Anyone
Can do it. My question is HOW do I prevent this from happening?
This clown (have no idea) locks me out of this account,but I always seem
To get back in after 12 hours or so.Yes. I have other accounts on Yahoo,but this is my main one. Any suggestions? This has been going on now for the
Last 6 months. Yahoo can't get the ISP from who is doing this and ban that
ISP from Yahoo? or if that person has several ISP's from other computer?(work,friends house,etc.)
Thanks!

If you think somebody is getting into your account - Change your password and your security question.

Make the password a mix of number & letters and possibly special characters (! $, % etc.) Then don't tell it to anyone.

Also make sure the security question is something that only you will know. For example, "What was the name of my favourite childhood toy?". That question would not be something you would forget. At the same time the only people who will probably know the answer to this are you and your surrounding family - people you can trust.


Might also be worth scanning your PC for any spyware using the links in my signature - just in case.

I'm curious as to what do you mean by "locked out". What happens when you try to get in? What error messages do you get? Do you see any activity (like Sent mail or mail marked Read that you didn't read) when you get back in?

Thanks Scott
I get a message"page unavailable" Can't remember what exactly comes up.
When I do get back in all is fine with my e-mails,and I never see anything
Suspious in there. I get the same response from Yahoo,that someone is always trying to get into my account and according to Yahoo,they "lock"
My account for security reasons. Then I have to wait sometimes 12 hours
To get back in. They tell me that if you log on to Yahoo,all you have to do is pretend you have forgotten your password. You click on "forget your ID or password?". You click on that and it takes you to another page where you have to prove "you" are that ID. You fill out things that you did when you joined Yahoo. Such as your birthday,zipcode,and where you live(USA,Canada,)etc. Then you put in your Yahoo name at the bottom of that page. But if someone knows your birthday and zipcode and what country you are from,they can type your Yahoo ID in ,change the password and they go in under your name.Yahoo makes this so simple. Then if you just guess where that person lives or their birthday and zip(any one of those subjects) and
Click on trying to change password about 6 to 8 times,Yahoo figures that someone is trying to log in and it's NOT you,they lock your account for your protection.And after they try 6 to 8 times,the top of the page will say "Temporary locked out to protect your account". I even made up another
ID and tried it,just to test the system. And it worked! Yahoo needs to improve this security at their servers,they even admit to that. So in reality,if you give someone your zipcode,birthdate.and what country to live in,they can actually get into your account and change your password. But in my case they are just guessing,and after a while I am locked out.! LOL.If you can try to read this and try to figure out what I am saying I hope I didn't give others on this site anything that would case grief on others.
Thanks
Candice

Page unavaliable doesn't mean you are locked out. That's the error message that's displayed when your internet browser could not find the page it was looking for - either due to troubles with your internet connection or Yahoo's servers being unavaliable.

Ahh now I understand. As LT said I don't think this is due to locking. How do you get to the Internet?

I just dealt with this - it took me four hours to figure out how to contact Yahoo to wrest control of my account back from the hacker. Call 866-562-7219 and ask to speak to customer service. They will work with you to get control of your account.
