Great to see it back up.
Wow. Well I would claim surprise but this is a bitcoin project... so...
*yawn* anything on the Internet related to money is a target

Also, simple injection is hardly a "0-day" exploit. The fact that you guys had completely unsanitized input on your forums software means you're every bit as responsible for the hack.

Not a zero day exploit anyway. This problem was identified ages ago and patched in SMF 2.x, if you are only running 1.x you are pretty much walking around with your pants down waiting to have your nuts twisted.
This is so irritating. So if I have a 14 character password with lower case + numbers + symbols what are the odds it will be cracked? I guess I should probably just change it anyway, to be safe. Good thing I don't use it anywhere else otherwise this would be even more irritating.

I just tried changing my password and it says my current password is wrong.
So I cannot change to a new one now.
Is it likely that passwords were changed on many/most accounts or did you wipe out old ones at some point?
BTW if the hacker still has some fingers in here then forcing us to enter our password for changing would expose the password. So hopefully some script wasn't modified to send passwords to him when an attempt was made to change it...
(Not a big problem for me as all my passwords are different and random 25 char strings)

I'm curious as to how it is a "0 day" attack when it's been patched in SMF 2.x and a few other versions previous of that, long long LONG ago.
This needs to be addressed, if true.
It may be fixed in 2.0, but 1.1.14 is still officially supported by SMF.
If we're ever willing to upgrade to 2.0, we'll probably just use some other forum software.
I'd like to see vBulletin used as well. I've read that it takes lower cpu load than most php free boards and it has some features I think would be nice here. Ubuntu forums and many other busy forums run on it. I know it costs some money but not that much.
Edit: I don't know if there is an import tool for vB. I'd hope so because losing past posts and all the info held in them is not really an option.

thanks for the info, theymos. please continue to keep things as transparent as possible.
theymos, thanks for getting the site back up so quickly. I'm sure it ruined your weekend.
Everyone should use lastpass.com and generate the longest password a site will accept (or just 32 random characters/numbers is sufficient imo) plus save that on lastpass.com
It's too easy and there is no excuse not to do it.

On September 3, an attacker used a 0-day exploit in SMF to gain administrative access to the forum. This went unnoticed until September 9, when he inserted some annoying JavaScript into all pages. The forum was at this point shut down.
The attacker was capable of running arbitrary PHP code, and he could have therefore copied all password hashes and read all personal messages. He also could have done all of the things that admins can normally do, such as editing/deleting/moving posts.
Passwords
It is not known for sure that the attacker copied any password hashes, but it should be assumed that he did.
SMF hashes passwords with SHA-1 and salts the hash with your (lowercase) username. This is unfortunately not an incredibly secure way of hashing passwords.
The password you used on the forum should be assumed to already be compromised if your password had:
- Less than 16 characters, numbers only
- Less than 12 characters, lowercase only
- Less than 11 characters, lowercase+numeric
- Less than 10 characters, lowercase+uppercase
- Less than 9 characters, lowercase+uppercase+numbers
- Less than 8 characters, all standard characters
If you have only 2-3 more characters than what I listed above, then you should assume that your password will be compromised at some point in the future.
No matter how strong your password was, it is a good idea to change your password here and wherever else you used it.
Database state
Backups exist of the previous database state, but it has been decided to continue with the latest state to avoid losing thousands of posts. If you notice that any posts are missing or changed, let me know.
Also, it's possible that the attacker took control of some accounts. If you are being impersonated, email me and I'll reset your password to its previous value.
More attack info
The attacker first paid for a donator account so he could change his displayed username. The displayed username field is not escaped properly, so he was able to inject SQL from there. He took over Satoshi's account, and from Satoshi's administrative interface he was able to inject arbitrary PHP code by modifying the style template.
The attacker probably used these user accounts, though his level of access would allow him to forge this data:
brad
EconomicOracle
Economic Oracle
SwimsuitPaul
BitcoinsInMyLoins
He probably used these IP addresses:
74.242.208.159
74.242.205.69
152.14.219.223
152.14.247.62
74.242.205.161
74.242.206.245
74.242.208.159
74.242.235.132
98.69.157.69
98.69.160.187
41.125.48.26
150.206.212.72
