Eclipse Attack Plugged in Ethereum Network


Maintainers of the Ethereum network have issued an update for the network's underlying codebase that fixes flaws described in a research paper released this week.

The researcher paper —authored by researchers from Boston University and University of Pittsburgh— describes a vulnerability named an "eclipse attack."

Eclipse attacks are network-level attacks carried out by other nodes by hoarding and monopolizing the victim's peer-to-peer connection slots, keeping the node in an isolated network.

These type of attacks are meant to isolate nodes by keeping up-to-date blockchain information from reaching the eclipsed node. The Bitcoin network was, too, vulnerable to eclipse attacks.

Two bad nodes are enough for an eclipse attack on Ethereum

Now, academics have discovered that Ethereum, the network of nodes that's the backbone of the Ether cryptocurrency and the myriad of smart contracts that support many other digital currencies and ICOs, is also vulnerable to eclipse attacks.
