Context

Blockchain technology heralded for its promise of decentralised and immutable records, has been lauded for its robust security features. While blockchain itself boasts high security, it is not entirely impervious to hacking. Various elements within the blockchain ecosystem have been successfully targeted by hackers, demonstrating that vulnerabilities do exist. Several factors contribute to the hackability of blockchain technology, ranging from human error to inherent system complexities:

Evidence

Pending intelligence enrichment.

Analysis

One of the primary reasons blockchain technology can be hacked is human error. Mistakes made during the development of blockchain applications, such as smart contracts, can introduce vulnerabilities. For instance, if the code has bugs or logical flaws, hackers can exploit these weaknesses to execute unauthorised actions. The infamous DAO hack in 2016, where a flaw in a smart contract allowed attackers to drain $50 million worth of Ether, is a prime example of such vulnerabilities.

Cryptocurrency exchanges, for example, operate as centralised entities where large volumes of assets are stored. These exchanges have been frequent targets of cyber-attacks. Hackers often employ techniques such as phishing, malware, and social engineering to gain access to these centralised repositories. Once breached, significant financial losses can occur, as seen in the Mt. Gox and Coincheck incidents. Also read: Can multi-factor authentication be hacked?

Key Points

  • Human error, centralisation points, 51% attacks, and social engineering are some of the factors that contribute to its hackability.
  • Lately, there has been a significant surge in blockchain breaches, as it has become evident to hackers that there are indeed exploitable weaknesses present.

Actions

Pending intelligence enrichment.
