Hello,

You are receiving this message because you have an account registered with this address on ubuntuforums.org.

The Ubuntu forums software was compromised by an external attacker. As a result, the attacker has gained access to read your username, email address and an encrypted copy of your password from the forum database.

If you have used this password and email address to authenticate at any other website, you are urged to reset the password on those accounts immediately as the attacker may be able to use the compromised personal information to access these other accounts. It is important to have a distinct password for different accounts.

The ubuntuforums.org website is currently offline and we are working to restore this service. Please take the time to change your ubuntuforums.org account password when service is restored.

We apologize for any inconvenience to the Ubuntu community, thank you for your understanding.

The Canonical Sysadmins.

Pregunto: ¿Pero vBulletin funciona sobre un Ubuntu Server en el caso de Canonical, luego fue la seguridad de Ubuntu Server la que fue vulnerada lo cual indica algún tipo de falla a nivel de Firewall, Antivirus o IDS?.

Quizás ciertos sitios web se puedan atacar con conocimientos medios, todo depende del tipo de seguridad implementada, sitios como Amazon, Google, Microsoft, entidades bancarias o alguna agencia del gobierno de USA no deben ser fácilmente vulnerables y el nivel de conocimientos para acceder a su información debe ser muy alto, si esto no es así entonces queda mucho camino por recorrer en seguridad informática :)

Bueno, el que sea ubuntuforums no quiere decir que tenga una seguridad especial, es un sistema estándar con el programa vBulletin,

No deja de ser una paradoja que Canonical monte su sistema de foros sobre software privativo.

egostar,
Pregunto: ¿Podrías explicarte un poco mejor, no me queda claro que comentas que sucedió? :confused:

Dear valued community members,


On the 22nd of July 2013, it was discovered that unauthorized access to our website and database has been obtained on the 20th of July.
The method is similar to the hacks that were recently conducted at other websites, even though those sites used other software.
One of the admins account password was discovered, and from there further escalation wasn't too difficult considering admin privileges can do just about anything.

Unfortunately, we are 100% sure that our user database has been stolen.
As such we HIGHLY RECOMMEND, even implore you, to:
1.) Change your password on other websites you are using, if you use the same password there. This is very important to do, as it also will help prevent other websites being hacked through your compromised password, if it is compromised.
2.) Change your password here on our website.
3.) If you use the password you use here anywhere else, say for example to login to your webhost, it is highly urged to change it.
4.) Please note that personal messages may have also been compromised. We don't know for sure if the hacker only downloaded the user tables or not, although that's the only thing he/she is after. If they did: keep in mind that passwords you shared through PM should now be considered vulnerable. It's best not to take the risk and gamble, and just change any password you shared through PM as well.
5.) Charter members, current and past, are encouraged to change ALL passwords if they ever sent any in to us. That would include FTP.

Please keep in mind:
This is !!NOT!! a security issue with the SMF software. If you are running the latest SMF version you have nothing to fear from this hack if you use different passwords.

The method used by the hacker is that a database is downloaded from another hacked website, the passwords are attempted to be decrypted and if it is successful: they try to login to other websites using that username & password, or try to cross-reference by using password reset links.
Unfortunately for us, a Administrator used the same password elsewhere on another site and access to our site was obtained when the password from the other hacked site was successfully decrypted. As a result, the hacker was able to login here with admin rights.
Hundreds of websites have been hacked lately by using this method, so you are highly encouraged to change your passwords...

... And remember: don't use the same password on multiple sites!
It helps to prevent hacks like this.

Thank you for your consideration and we deeply apologize for any inconvenience this causes for you.
By changing your passwords, you will help ensure that other sites do not fall victim to this method of hacking and help put a halt to the hacking spree that has affected hundreds, if not thousands, of websites already.

-edit for clarification-
Yes, the passwords are stored with encryption.
Unfortunately, even encrypted passwords can be decrypted. Hence, the passwords used here should not be considered safe anymore.


Any questions, please do feel free to ask.
Please stay on topic.


Kind regards,
Board of Directors
Simple Machines

Creo que ubuntuforums no tiene "nada que ver" con canonical ni con ubuntu...

Login has changed. Please read BEFORE logging in!

Ubuntu Forums is now using Ubuntu SSO at login.ubuntu.com for authentication. For more details, please see here.

For those new to the forum please register on login.ubuntu.com and then return to this page and login to the forums by clicking on the “Login with SSO” button at the top right of the page. If you already have an Ubuntu One (SSO) account, you need only click on the “Login with SSO” button.

If you have an existing Ubuntu Forums account please ensure that your preferred email address on login.ubuntu.com matches that associated with your Ubuntu Forums account. This way your accounts will be linked automatically. If you have an Ubuntu Forums account but no Ubuntu One (SSO) account, please go to login.ubuntu.com and create an Ubuntu One account with the same email address associated with your Ubuntu Forums account.

By logging in via Ubuntu One SSO, you agree to abide by the Ubuntu Forums Code of Conduct.

Y eso sí, si es verdad que usan vbulletin, es realmente vergonzoso que la gente de Ubuntu use una aplicacion NO LIBRE para su foros.

xBSD (que Apple tomó como base para su SO) sí es libre, pero la liencia BSD permite que los desarrollos derivados puedan ser privativos, que es lo que hizo Apple: su SO es (bien) cerrado.
