Popular digital currency forum BitcoinTalk has been hacked by a group calling themselves "The Hole Seekers".
The site is now down, but for a period, it displayed animations of bombs exploding and photos of classical music conductors, all set to the 1812 Overture, which is also the soundtrack to the explosion scene in V for Vendetta.
Toward the end of the animation, a banner was displayed, stating:
Theymos, the administrator of BitcoinTalk, told CryptoLife.net that the attack was worse than he originally thought.
"There’s a good chance that the attacker(s) could have executed arbitrary PHP code and therefore could have accessed the database, but I’m not sure yet how difficult this would be. I’m sending out a mass mailing to all Forum users about this," he explained.
Theymos summarised that the forum will be down for a while and said he thinks that password hashes were not compromised, but he can't be sure at this time.
The administrator said the attacker injected some code into $modSettings['news'], which is the news at the top of the forum pages. Updating news is normally logged, but this action was not, so Theymous believes the update was done in "some roundabout way" and not by compromising an admin account.
"Probably, part of SMF related to news-updating or modSettings is flawed. Possibly, the attacker was somehow able to modify the modSettings cache in /tmp or the database directly," he added, concluding:
Michael Parsons, of BitcoinByte.com, said: "Whoever hacked the BitcoinTalk forum has deliberately confused the 'illegality' of the Silk Road site with bitcoin in general."
He went on to say bitcoins were seized from Silk Road not because they're inherently illegal – which they’re not – but because they played a part in money laundering.
"Any money, either State fiat or decentralised bitcoin, found during a drug bust would be seized," Parsons clarified.
He suggested BitcoinTalk may have been hacked in an attempt to undermine the bitcoin protocol, thus damaging confidence in the ecosystem.
"Perversely, I think it will be a benefit to the bitcoin community, as it will encourage debate about bitcoin and how it is not illegal just because some hackers say so," Parsons concluded.
One forum member links to a screen shot of IRC, which appears to show a conversation between Theymos and another user, with Theymos stating a SomethingAwful "goon" was responsible for the hack. All BitcoinTalk users are advised to change their forum passwords.
