so, the question of "what security risk" is involved in POS coins that every coin is susceptible to just got answered in the most brutal way possible.
?
VRC 51% attack just became a very real scenario, they don't need half the coins... just half the staking amount, of which more than 51% was stolen. I cant say whether that is the problem cloakdevs fixed or not, but I imagine it has something to do with that. It's at least a sobering reminder to keep your coins in your wallet...
Where did these details come from?
check the VRC thread?
wow. scary reading.
Please read the entirety of this post.
A few hours ago we were unfortunately the subject of a successful attack against the exchange. Our investigations have shown that whilst our security was breached, VeriCoin was the target. We would like to stress that VeriCoin and the VeriCoin network has not been in any way compromised. We have worked to secure the exchange and the withdraw process from any further attack.
As it stands at the moment the following applies:
1) We lost a considerable amount of VeriCoin in the attack, however we have been working with the VRC developers and all major exchanges to hard fork the coin at a position before the attack. This will allow us to retrieve the stolen coins and facilitate all withdrawals. We are also working with various exchanges to accommodate any losses they may encouter as a result of the required fork.
2) We are currently processing withdrawals for all other coins.
As I'm sure you will appreciate, our support channels will most likely be very busy over the coming hours/days so please bear with us.
We would like to personally extend our thanks to the VeriCoin developers and the other exchanges who have pulled out all of the stops to ensure that your VRC funds are safe.
The problem was in mintpal but it will effect mostly vericoin. I believe it won't cause significant dump after everything is fixed but who knows
This reminds me never ever keep your coins on just one exchange !!
