Bitcoin poker web site Seals with Clubs has confirmed that its database was compromised, though it failed to mention that it lost 42,020 hashed passwords in the method. The hashes have been posted to a forum some 24 hours earlier and needless to say they attracted plenty of people bent on cracking them.
For some cause Seals with Clubs employed SHA1 hash functions, which are for all intents and purposes obsolete. Even the latest SHA3 hash is not appropriate for passwords and it seems that the web site was relying on cryptographic salting to make them more secure, generating confident that different hashes would be employed even if two customers chose the precise exact same password.
In any case, it did not take lengthy for individuals to begin figuring out some passwords, such as “bitcoin1000000”, “sealswithclubs”, “88seals88” and “pokerseals”. The revealed passwords swiftly led safety specialists to join the dots and conclude that the passwords came from Seals with Clubs customers.
On Wednesday, a user posted the database of hashes to a password recovery forum operated by commercial password cracking service InsidePro. The user supplied $ 20 in bitcoins for every single set of a thousand distinctive hashes. It took just nine minutes for the first reply and the very first set of 1,000 hashes. Inside a day, about two thirds of the list was cracked, reports Ars Technica.
By Thursday, Seals with Clubs was in harm control mode, officially admitting the breach and announcing that it has issued a mandatory password reset. A post on its site study:
The datacenter that we employed up to November permitted unauthorized access to a database server and our database containing user credentials was probably compromised. Passwords have been salted and hashed per user, but to be safe every user Should alter their password when they subsequent log in.
Please do so at your earliest opportunity. If your Seals password was utilised for any other purpose you need to reset these passwords as well as a precaution.
The site pointed out that it would implement added security measures, including two-factor authentication and login from a restricted number of IP addresses.
This, even so, will not address another problem. Since Seals with Clubs is a bitcoin-only service, each account holder is a bitcoin user and there is very good likelihood that at least some of them reused the identical password on other bitcoin sites. In other words, some users may well be making use of the exact exact same password on their exchange accounts or on the web wallets.
As for Seals with Clubs, it is a comparatively small website compared to significant Texas Hold’em internet sites out there. The little group of poker players behind the internet site chose to stay anonymous and the internet site was apparently launched following they were sacked. We hope playing poker in the course of office hours had nothing at all to do with it.
