ETC Team to Report on EAgharta Scam

The "project" appeared the day after the Agharta hardfork, so devs believe it may be from the people that were doing similar after Atlantis

The Ethereum Classic (ETC) development team warns traders of a fraudulent EAgharta project trading non-existent Agharta coins on behalf of ETC. It appeared the day after the Agharta hard fork on the Ethereum Classic blockchain.

On January 12, Agharta hard fork was successfully activated on block 9 573 000 in order to improve the compatibility of the ETC network with Ethereum. In all likelihood, scammers decided to take advantage of this event and began to trade Agharta coins, hoping to confuse traders.

Representatives of the fraudulent EAgharta project posted a tweet on behalf of Ethereum Classic with a link to their website, where users are asked to enter and save a password to create a new wallet. As stated on a fake site, otherwise users cannot access the account, restore keys, reset passwords or cancel transactions.

Potentional Vulnerabilities Found in ETH 2.0

Least Authority have found potentional security issues in the network P2P interaction and block proposal system

Technology security firm Least Authority, at the request of the Ethereum Foundation, conducted an audit of the Ethereum 2.0 specifications and identified several potential vulnerabilities at once.

Least Authority said that developers need to solve problems with vulnerabilities in the network layer of peer-to-peer (P2P) interaction, as well as in the block proposal system. At the same time, the auditor noted that the specifications are "very well thought out and competent."

However, at the moment there is no large ecosystem based on PoS and using sharding in the world, so it is impossible to accurately assess the prospects for system stability.
Also, information security experts emphasized that the specifications did not pay enough attention to the description of the P2P network level and the system of records about Ethereum nodes. Vulnerability risks are also observed in the block proposal system and the messaging system between nodes.

Experts said that in the blockchains running on PoS, the choice of a new block is simple and no one can predict who will get the new block. In PoS systems, it is the block proposal system that decides whose block will fall into the blockchain, and this leads to the risk of data leakage. To solve the problem, auditors suggested using the mechanism of "Single Secret Leader Election" (SSLE).

As for the peer-to-peer exchange system, there is a danger of spam. There is no centralized node in the system that would evaluate the actions of other nodes, so a “malicious" node can spam the entire network with various messages without any special punishment. The solution to this problem may be to use special protocols for exchanging messages between nodes.
