How the Latest Geth Exploit is Affecting Ethereum users?

The attack of bugs in a technology where millions of people are connected to transfer sensitive data is a matter of deep concern. This year Ethereum users faced this unfortunate issue. Ethereum is the 2nd most used blockchain platform for cryptocurrency transactions. Though the platform maintains high security and quality functionality, it is still open to a few vulnerabilities. Such drawbacks increase the chances of corruption even in decentralized services and give rise to massive outages. 

This article discusses the impact of Ethereum latest Geth exploit.

What is Geth, and how does it function as an Ethereum client?

Geth, also known as Go Ethereum, is an approved client software facilitated by the Ethereum platform. It uses the Go programming language and functions by connecting the different nodes or Ethereum clients with the network. It can keep a copy of the blockchain and continuously interacts with other networks to keep the copy updated. 

It likewise takes part in block mining. It streamlines and verifies transactions on the blockchain platform. Geth can also work as a server using APIs. In addition, it comprises the Geth console, which is a javascript client to connect blockchain networks.

Geth Ethereum client is basically a type of software that is accessible to users who want to check the authenticity of transactions on the network. The prime function of the software is running nodes. It is considered that when a network maintains a more significant number of nodes, its decentralization technique is always high-class. According to data, currently, the Ethereum network has 5289 nodes, followed by bitcoin, which is leading with 11,858 nodes. Moreover, Geth client software comes around as the most downloaded software with a current user base of 3947 members. 

Using the Geth software client, users are running easy and quick transactions on the blockchain. Such services allow users to have financial freedom as now they can have complete control over their finances without needing intermediaries or approvals from third parties. This easy-to-use platform has also given rise to considerable numbers of crypto miners and traders who efficiently earn reasonable amounts of money by providing services like faster crypto mining, transaction computing, etc. With the emergence of opportunities, competition is also high in the field. However, someone with excellent skills and knowledge of blockchain technology can make profitable deals in the crypto space. Remember that one can gain such expertise only through extensive experience with the technology proceedings. 

What is happening in Ethereum's recent Geth exploit?

Geth or Go Ethereum, famously recognized as "Ethereum's software client," encountered huge exploitations on its earlier versions, particularly v1.10.7. The exploitation took place due to a security vulnerability of the Ethereum blockchain. When attackers exploit such vulnerabilities, it usually affects the Ethereum mainnet. In the latest Geth exploitation, users are experiencing the following issues:

● Chain split due to consensus vulnerabilities. Chain split implies that affected Ethereum nodes will get divided from the main chain. 

● Users are facing service denials at the time of block generation. This has increased the chance of an unauthorized transaction resulting in a network crash for the Geth users.

● Users aren't getting the facility of peer-to-peer networking, causing the unavailability of the network.

As per data, a total of 74% of Ethereum users use Go Ethereum, of which 73% use the older version of Geth. The estimate indicates that more than 54 % of nodes are in contact with the bug. This flaw was first discovered in August this year by Guido Vranken, who is a software security expert. He states the bug came to the surface during a security engagement process.

Go Ethereum developers released a new hotfix of v1.10.8 or above. They claim to be free from high severity security vulnerabilities. Around 50% of the Ethereum users have updated to the latest version leaving the rest at high risk. However, old version users are now in worry about vulnerabilities that come with chain-split issues. That is obvious as such exploitation is undoubtedly dangerous and results in outages. And this affects the overall functionality of blockchain services as well as cryptocurrency exchanges. 

The impact of the Geth client exploitation

The latest exploit on the Geth software client has generated a fork within the Ethereum network. Right now, the platform is processing two different chains simultaneously, leading to a double-spend attack.

By double-spend attack, we mean that the network will spend a single cryptocurrency two times, which might turn into an unauthorized transaction. This will affect all the digital assets stored on the network by devaluing them. Further, all the other chains connected with Ethereum virtual machines will also be exposed to the bug. High-risk chains are Binance smart chain and polygon smart chain. 

Though some parts of the nodes are experiencing chain split, it seems that this bug is actually not affecting a large portion of the network. The majority of members have already installed the updated version provided by Ethereum. 

Only the node operators and miners who are running the older version of Geth aren't able to access the leading network. In conclusion, some network portions are undoubtedly getting affected by exploits, but all over the network is stable. 

It is found that the members of the three well-known mining pools, including BTC.com, Flexpool, and Binance, are under the radar of this latest exploit as all three of these pools are still using older versions of Ethereum. However, flexpool was quick to address the issue and is under review by developers. 

Conclusion

From the above article, we can deem that the only solution to get rid of this bug is updating to a new version of Ethereum. However, users will have to lose all the transaction details they made on the forked network. But, since the exploit took place, only a few transactions have been made, so updating to the new version won't be that much of a loss. If you plan to download the Geth software client on your Ethereum platform, then make sure to go with the latest version only. Also, it would be helpful if you keep your network linked with the latest updates.
