Can you still login to your account? Was the password a unique secure password or a password you used somewhere else?

Yes I could log into the account. I changed the password as well but my gut feeling is they did it without the password. Just real strange for them to post to my account like I have 50 followers maybe. Take out the trash and I probably have 10 real followers.

Found the source of the spam. [nakedsecurity.sophos.com...]

The article is an old one but I bet this is were the spam is coming from.

But how did it post from your account?

Did tweetmeme post it on your behalf, i.e. you gave it permission to access your twitter account?

As far as I understand, the linked article isn't claiming the tweetmeme caused the original tweets to be sent. It's saying that because so many accounts were making these tweets, it was picked up by tweetmeme giving it further exposure.

That's the way I read it. Either the account was hacked, or a third party app / site with access to the account posted it.

+1 on the apps suggestion. Go thru your Twitter profile apps list and remove all unessential ones.

Been reading it over again and as Status_203 said this probably isn't the hack. Been so busy I just scanned it but took some time to go over it. I am now not sure how it happened. I know the pass was not one that a program could get. All my passwords are were this won't happen. If it was a hack from my pass then why not change the pass and tweet more. Something just doesn't add up. This is my first hack in 12 years. I am the only one with the pass and user name I don't store my passwords, so I have no idea how it happened. I do know there have been others tweeting the same message. Intresting to see if more information comes out in the future on this. I really would like to know.
Hoople thanks I do have one account connected to twitter ratepoint. Hmm let me look into that as a possibility.

Looked for a connection with ratepoint app and just can't find anything to connect.

My Account Has Been Compromised

My first and only guess would be the third party connection. If you are that sure about your password, that leaves one other option, the third party connection.

Unexpected updates don't always mean that your account was hacked. Occasionally, a third-party application can have a bug that causes unexpected behavior. If you see strange behavior, changing your password and/or revoking connections will stop it, as the application will no longer have access to your account.

Just same thing happened to my Twitter account as well few days back. Someone posted tweet like this “earn easy money…$300” with a tiny URL and I was surprised that who did it when I haven’t shared my password with anyone. I just deleted those tweets and changed my password.

It can happen if you fell for phishing.

You receive an email, or click on a link which you think takes you to the default twitter page. You enter your usename and password, get redirected to the main twitter site but your details are captured and used later for spam.

Never click links in emails for anything to do with twitter, facebook, myspace, banks, google, etc and etc. It had to have happened through the app. I have discontinued that service and taken them off my site.

It is true, there are a lots of hackers who seeks profile of big brands. You must never click on the unwanted links mailed to you as spam.
