CyberSanctus - Company Cover
Ever since our inception, our vision has been to help companies, primarily in Web2, to help combat the increasing amount of cyber threats that are on the rise. We have been lucky enough to have received support from some great mentors, as well as financial support from a key university in the UK.
The Necessity for Web3 Cyber Security Solutions
With the rapid development and expansion of the Web3 ecosystem, a growing number of cybersecurity concerns emerge; the architecture of the internet experiences continuous change, presenting both opportunities and cybersecurity risks that organizations need to address. The shift in internet architecture towards Web3 entails a data-based web in which not only human agents are able to access, aiming towards a decentralized and trustless system. machine agents are ingrained within the web3 ecosystem, with the ability to access and process the data ecosystem. With Web3 turning everything on the web into a massive database accessible to both human and AI agents, a number of security concerns arise. This paper aims to discuss the necessity for Web3 cybersecurity solutions through an examination of analytics on the growth of the blockchain industry.
Analyzing High-Profile Cybersecurity Breaches in Web3
In the past decade, there has been ever-growing hype around the idea of Web3, and the market has sparked global interest and ushered the internet into a new era of decentralization, transparency, and innovation. Web3 technologies, built upon blockchain and decentralized protocols, come with the promise to revolutionize various industries, including finance, supply chain management, and digital ownership through various different blockchains. However, similar to most new innovations in the software sphere, they each come with significant cybersecurity challenges, and with the mass adoption of blockchain technologies within high-profile businesses, we have spiraled into an ever-growing need to implement cyber security solutions.
The Role of Bug Bounty Programs in Web3 Security
-
As different industries adopt the blockchain into their systems, as an essentially software-based product, it is inevitable that software bugs, security flaws, and vulnerabilities will at some point appear in the systems (Melo, 2023). The inevitability of bugs and vulnerabilities in smart contracts and blockchain-based systems presents important security issues; if malicious actors uncover vulnerabilities within a smart contract, they will be able to exploit and cause damage to the system. As such, it is crucial to identify these vulnerabilities in order to mitigate and prevent any attempts by malicious actors to exploit these gaps. In this paper, we will explore the role of bug bounty programs in identifying and addressing security vulnerabilities in blockchain-based systems.
Case Study: Secure Smart Contract Development
-
The objective of this section is to investigate the architectural principles, design patterns, and best practices that are necessary to build secure smart contract systems. It is essential to acknowledge that security in smart contracts is not an afterthought but a fundamental component of their design and implementation, even more than that of the web2 space, and a proactive approach will almost always result in safer code.
Ethical Hacking Techniques for Decentralized Finance (DeFi) Platforms
-
This paper (a section of the ebook) focuses on ethical hacking within the Decentralized Finance (DeFi) ecosystem, highlighting the nuanced security challenges these platforms face. As the DeFi ecosystem continues to grow and impact the finance sector, offering innovative lending, borrowing, and trading services through blockchain technology, it has become a prime target for malicious actors. This study not only introduces readers and gives security insights to the foundational operations of DeFi platforms, such as collateralized loans or the broader idea of how decentralized exchanges operate through smart contracts, but also indicates the critical need for proactive security measures. Through the incorporation of practical lab walkthroughs, this paper aims to give insightful information to developers, junior auditors, enthusiasts, and DeFi users on the security challenges faced in DeFi, and on adopting an attacker mindset when searching for vulnerabilities.
