SlowMist’s Latest Warning 

SlowMist alone has discovered many common high-risk security vulnerabilities in the industry, and recently on twitter, it warned users to be cautious of Multiple Omni USDT Double spend Attacks.

The warning comes after the Omnicore, “an enhanced bitcoin core that provides almost all the features of the bitcoin and advanced Omni layer features” team has fixed a major security vulnerability.

Omnicore: Vulnerability

The vulnerability was that the Omnicore’s node could not properly handle the “sync lock’ problem when receiving a new block. An attacker can exploit that to specifically construct a block to cause multiple transactions to be recorded in one transaction, which results in account balance wrong in the ledger.

SlowMist Security team reminds it by this method the users who are using the old version of nodes such as 5.0 can easily be targeted and hack into the account balance to display it incorrectly.

The double-spend attacks by using not updated nodes is a standard hacking method, and it is very hard to spot such attacks.

To prevent this type of attack, the best way is to be up-to-date and upgrade the node to the latest version (0.8.0) in time.
