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.

A double spend is an attack where the given set of coins is spent in more than one transaction. There are a couple main ways to perform a double spend: Send two conflicting transactions in rapid succession into the Bitcoin network. This is called a race attack. Bitcoin and the Double-Spending Problem . Many digital currencies face the problem of double-spending: the risk that a person could concurrently send a single unit of currency to two different sources. This moral hazard arises due to the trivial reproducibility of digital information, and the information asymmetry that can result from this. 3. RBF – “Legit” Double Spending. One form of “legit” double spending is Replace By Fee or RBF for short. RBF is a function embedded in certain Bitcoin wallets (e.g. Electrum) that allows you to rebroadcast a transaction that is still unconfirmed, in order to get it confirmed faster.. In some cases, Bitcoin transactions are sent with a network fee that is too small to incentivize Bitcoin manages the double spending problem by implementing a confirmation mechanism and maintaining a universal ledger (called “blockchain”), similar to the traditional cash monetary system.. Bitcoin’s blockchain maintains a chronologically-ordered, time-stamped transaction ledger from the very start of its operation in 2009. Double-spending problem is the successful use of the same funds twice. Double-spending of Bitcoin is not possible as Bitcoin is protected against a double-spending problem thanks to each transaction which is added to the blockchain being verified, and the majority of funds contained in this transaction cannot have been previously spent.. Double-spending is a potential flaw in a digital cash
