Now, that we know all about Blockchain security, the next question that comes up is how fraudsters attack Blockchain technology. Hackers and fraudsters can harm the system in 4 primary ways.
Letâ€™s discuss them in detail -
1. Phishing Attacks -
Phishing is a scamming attempt where an imposter poses as a reliable source in order to attain important credentials. It is one of the oldest forms of hacking that has been documented.
Using fake hyperlinks, hackers aim to get confidential information. By hacking the unique IDs, phishers can harm the entire Blockchain system.
2. Routing Attacks
Blockchain systems rely on real-time, large data transfers on a regular basis. This type of attack involves data being covertly intercepted by hackers as it travels over a network, typically WiFi networks.
In a routing attack, blockchain participants are unaware of the threats, so everything looks normal. Hackers monitor userâ€™s deals and transactions and extract confidential information, data, or currencies.
3. Sybil Attacks
In a Sybil attack, hackers attempt invalid logins using stolen credentials to bring down a Blockchain system. Hackers use a plethora of false network identities to flood the network and crash the system.
4. 51% Attacks
If a miner or a group of miners could rally enough resources, they could attain power over more than 50% of a blockchain. Attaining a significant power gives miners complete control to regulate and manipulate ledgers.
5. Computer Hackings
Distributed ledger technology is just as susceptible to computer hacks, as any other. A hacker can easily play with the entire Blockchain network, authorized by you.
Blockchain Security for the Organization
In order to ensure complete security of the Blockchain system, it is important to ensure proper security at all levels of the technology stack. Incorporating tried and tested Blockchain security audit measures is essential for all kinds of enterprises.
