03-06 11:04 - 'Be Cautious of Multiple Omni USDT Double-spend Attacks' (self.Bitcoin) by /u/SlowMist_Team removed from /r/Bitcoin within 83-93min

'''
Recently, the OmniCore team has fixed a major security vulnerability. As the node does not properly handle the “sync LOCK” problem when receiving a new block, an attacker can send a specially constructed block to cause multiple transactions to be recorded in one transaction, making the account balance wrong.
Earlier, the SlowMist security team captured a USDT false top-up attack incident against the exchange. After analysis, it was found that because some exchanges used older versions of the OmniCore client (such as 0.5.0). Meanwhile, Hackers used the carefully constructed transfer transaction, which can be marked as a successful transfer on the client of the old version and displayed as failed on the client of the new version, thereby achieving the purpose of false top-up.
The SlowMist security team wants to kindly remind the relevant node operators that conducting double-spend attacks by using un-upgraded nodes is a common hacking method, especially on layer 2 solutions such as OmniLayer. Such attacks will not cause the main chain to fork,it is not easy to be found. Therefore, It is wiser to be vigilant and upgrade the node to the latest version (0.8.0) in time.

Bitcoin Gold hit by Double Spend Attack (51% attack). The Attacker reversed 22 blocks.

Just came across this story on CCN.
This, I believe, is the first 51% attack on any major cryptocurrency. BTG's target blocktime is 10 minutes. Rewriting 22 blocks means the attack had majority hash power for 3.5 hours. And since BTG runs EquiHash, this would mean any coin running Equihash are also in danger.
