Hacker Attack Against Ethereum Was Unsuccessful

Crypto-hackers are notorious for spotting even the smallest weaknesses in networks and exploiting them, typically with different degrees of success. Ethereum has emerged as a target for one or more of them in the previous 24 hours.

 

On Tuesday, an unknown hacker attempted, but failed, to assault the Ethereum network. While it was successful in fooling a few nodes, it was unable to fool the entire network.

 

On Twitter yesterday, Ethereum developer Marius Van Der Wijden disclosed the same thing, alleging that the attacker published a long chain of roughly 550 blocks, all with false proofs of work. This implied that, rather than following the prescribed procedure for mining blocks, the attacker produced them at leisure and broadcasted them to the rest of the network.

A minor number of nodes running Nethermind, an Ethereum client, were duped into switching to an incorrect chain. However, because the proofs of work were forged, the majority of Ethereum nodes rejected this extended sidechain.

 

The sidechain holding the forged blocks has now been supplanted by the main Ethereum blockchain, prompting all impacted nodes to return to it.

This incident, according to the developer, was “another great demonstration of how client diversity makes Ethereum stronger”

 

The Ethereum network was impacted earlier this month when a significant issue struck the most common software used to verify transactions on the network, ‘Go Ethereum’ or ‘Geth.’ After 54 percent of nodes, particularly those that had not updated their software, were afflicted by the problem, half of Ethereum’s ecosystem separated into a sidechain.
