Blockchain Vulnerabilities Routing Attack Training Ppt

Slide 1

This slide showcases the concept of routing attacks in the blockchain. It explains that the routing attack divides the blockchain network system into two separate components as the attacker creates a parallel blockchain network to conduct the attack. During this kind of attack, within the blockchain network are unable to communicate with nodes outside the network.

Slide 2

This slide illustrates the different ways by which routing attacks can be stopped in the blockchain such as avoid using 'admin' as user name, for extra security change the firmware, ensure encryptions are regularly updated, and check who’s connecting to the network.

Instructor’s Notes:

Different ways to prevent routing attacks are as follows:

Avoid using 'admin' as user name:

• It is critical not to leave the username as admin in a blockchain network and change the password and username from time to time
• The malicious hackers can identify the user name and password and hack the system 

For extra security, change the firmware:

• A recent survey found that around 80% of the top-selling routers on Amazon are vulnerable to hacking, which puts blockchain network systems at severe risk
• It is essential for blockchain networks to have a better security system to avoid routing misuse by malicious hackers

Ensure encryptions are updated regularly:

• Although routers are fairly reliable devices, but can be vulnerable to malicious hackers if not changed over time
• If the router encryption is not changed, it can lead to a mal-functioning blockchain network system 
• Routers with WEP encryption are vulnerable and should be replaced over time to avoid any attack on blockchain networks

Check who is connecting to the network:
