Blockchain: A Shield Against Cybercrime

The annual increase in cybercrime losses has reached unprecedented levels, causing growing concern across industries. Experts suggest that while blockchain technology may not entirely eliminate cybercrime, its widespread adoption could significantly aid in mitigation. Cybercrime manifests in numerous forms, including ransomware attacks, identity theft, data breaches, and phishing schemes. Research from Cybersecurity Ventures indicates that global cybercrime losses might escalate to $10.5 trillion annually by 2025.

The inception of the first decentralized blockchain, known as Bitcoin (BTC), occurred in January 2009, alongside its associated cryptocurrency. Blockchain incorporates essential security features such as cryptography, decentralization, and consensus mechanisms. Ronghui Gu, co-founder of the blockchain security firm CertiK, asserts that blockchain fundamentally serves as a security technology. He believes that sectors reliant on data integrity, like healthcare and finance, could enhance their security through blockchain implementation. For instance, storing patient records on a blockchain could reduce risks of unauthorized data access and breaches, giving patients more control over their information.

Many companies have already started to explore the potential of blockchain in managing medical records, including issuing COVID-19 medical certificates on the blockchain. Gu points out that the centralized nature of traditional data storage systems renders them attractive to cybercriminals. Existing systems often lack sufficient mechanisms for users to verify data usage and access. He suggests that blockchain and Web3 technologies can address these issues by decentralizing data storage and minimizing the risks of centralized points of failure.

Blockchain’s distributed ledger technology aims to eliminate single points of failure, making the system more resistant to traditional cyberattacks like data tampering and network infiltration. Unlike centralized systems, blockchains distribute data across numerous computers, making it significantly difficult for attackers to control the entire network. CertiK’s 2023 report shows that while blockchain provides stronger security, it is not immune to cyberattacks. In 2023, over $1.8 billion in digital assets were lost across 751 Web3 security incidents.

Data from Statista reveals that investment scams led to the highest financial losses in the United States last year, followed by business email compromise and fraudulent tech support schemes. These types of attacks often involve tricking victims into transferring funds to scammers, resulting in financial losses and exposure of sensitive information. Gu believes that smart contracts, integral to blockchain, could reduce such cyberattacks. Smart contracts execute transactions only when predefined conditions are met, potentially minimizing financial fraud and automating compliance tasks.

Despite its potential, Gu concedes that completely eradicating cybercrime is unrealistic due to the ever-evolving nature of cybersecurity. As new technologies emerge, so do new vulnerabilities and attack vectors. A significant proportion of cybercrime exploits human errors, such as weak passwords or phishing scams. The goal, he argues, should be to minimize cybercrime and mitigate its impact through resilient infrastructures and well-informed users. This strategy preserves the advantages of decentralized technologies while protecting against inherent risks.

Johann Polecsak, co-founder and CTO of QANplatform, opines that blockchain alone isn’t a panacea for all types of cyberattacks. It can narrow down points of failure to key-management issues, which can be mitigated using hardware-based signing tools. Polecsak also emphasizes the importance of choosing blockchains designed to resist quantum computing attacks, as quantum computing poses a significant future threat to the crypto industry. A quantum computer could potentially break blockchain encryption, leading to large-scale thefts.

Fraser Edwards, co-founder and CEO of Cheqd, sees many opportunities for blockchain in preventing cyberattacks, specifically phishing and impersonation scams. Hornetsecurity’s 2024 report indicates that phishing remains the most common email attack method. Edwards believes decentralized identity and credentials, often underpinned by blockchain, can drastically reduce these attacks. Blockchain tech could even counter new threats like AI-generated scams. As deepfake technology becomes more sophisticated, creating indistinguishable fake images and voices, blockchain could provide solutions through methods like decentralized identifiers (DID) and content credentials.

Edwards further argues that blockchain could prevent the use of AI-generated documents in KYC processes. Decentralized identifiers and credentials could add an extra layer of security, requiring correct cryptographic signatures for authentication, thereby preventing document forgery and ensuring genuine verification. This approach could curb the rise of cybercrimes driven by advancements in AI, maintaining the integrity and security of digital interactions.
