Forum passwords.

[Anonymous]

Are they properly encrypted and salted? Again, it seems the site has been compromised. Should we be changing our passwords?

No one cares about fakeposting under your account, but checking if a site properly salted/hashed passwords should have been done before we all signed up.

Thanks for the insight.

1. No one cares about your bitcoin forum account.
2. SHA1 is insecure and broken.
3. This is running an extremely outdated version of SMF.

You don't need to bruteforce it and get what password you used. It's SHA1. You just need to have another input that results in the same hash.

Note that the typical attack will be running a stolen database through dedicated cracking rigs. About 1/5 of user's mtgox passwords were cracked and published within days of the compromise. It was also clear that the original plaintext was found and not some hash-matching string of garbage.
