We patched it quite some time ago, and confirmed that the Monero blockchain had NEVER been exploited using this, but until the hard fork that we had a few weeks ago we were unsure as to whether or not the entire network had updated.
Once we were certain that the network had updated, we notified all active and affected CryptoNote coins, including CryptoNote themselves, Bytecoin, Forknote, Boolberry, DashCoin, and DigitalNote.
Note that, at this time, only Monero, Aeon, Boolberry, and Forknote have updated. We have given the other currencies as much time as possible, but cannot hold back disclosure any longer.
We strongly caution against anyone using, trading, exchanging, or running services involving the following currencies affected by this issue: Bytecoin, DashCoin, DigitalNote
Bytecoin need bugfix immediately.
when this article has been written? Just when Bytecoin rise to be just below his small brother Monero? why we have not seen this information until now? Anyway it is just a matter of time for Bytecoin to kick Monero from the 9th place. Let enjoy the Ride.
Backdoors are just fine, just look ETH!
