OpenSecurity: Why Web2 Security is a necessity for Web3 Protocols

Cantina Bouncer

Oct 18, 2023


This article serves as a case study of how Open Security, a guild on Cantina offering traditional Web2 security services, conducted a time-critical, client-tailored source code review and penetration test on ArConnect - a non-custodial Arweave native wallet by Community Labs - to meet product rollout timelines.


Through Cantina, companies, projects, and agencies alike will be able to submit requests to a wide and open marketplace, quickly receive quotes from multiple parties, and hire freelance talent directly via a reputation system that allows individuals and groups to stand out on their merit alone.

Open Security

Open Security is an award-winning, veteran-owned cybersecurity firm servicing clients worldwide. With decades of experience defending networks from the latest threats, their mission is to make cybersecurity accessible.

Community Labs and ArConnect

Community Labs is a software development company and venture studio focused on accelerating developer tools, use cases, and adoption of Arweave. One of their products, ArConnect, is an Arweave-native wallet extension that provides a non-custodial wallet and asset management in your favorite browser. The extension allows Arweave wallet holders to interact with any dApps without sharing their private keys with them. The isolated environment that ArConnect creates is not only a security improvement for users, but it also provides a more seamless login flow for applications.

Value Alignment

In the realm of the Web3 ecosystem, a myriad of projects are placing an intense focus on enhancing the security of their blockchain infrastructures. This emphasis on fortifying blockchain ecosystems has been a pivotal development, but it has also become increasingly clear that there is a pressing need to address the security concerns inherent in the traditional Web2 framework. The foundational role that Web2 plays in the burgeoning Web3 ecosystem necessitates this heightened attention to its security elements.

Before the summer of 2023, Cantina’s customers needed to seek and evaluate independent companies to perform traditional penetration testing and Web2 security services. While Cantina and its clients maintain high technical skillsets and security resources, no organization can do it all. Open Security complements the already robust capabilities of Cantina and its clients by providing a holistic approach to cybersecurity, with a focus on traditional penetration testing and Web2 security.

A truly secure environment is built not just by addressing existing vulnerabilities but by proactively identifying and mitigating both legacy (Web2) and contemporary (Web3) threats. The need for traditional vulnerability management, penetration testing, and traditional source code reviews is evident as key figures and protocols are suffering from front-end / server-side exploits, account takeovers, credential/key theft, social engineering, and many other attack vectors that we should be increasingly mindful of.

Open Security leveraged the Cantina Guild Service, a model where each guild, operates as a unique security services provider, having its own set of standards to ensure quality. This creates a more systemic deal flow for guilds where Cantina can efficiently allocate the security needs of clients towards industry experts depending on the available skillsets across guilds.

The Security Review

The testing phase was initiated on July 3, 2023, and concluded on July 17, 2023. This period was marked by a review of the source code to identify vulnerabilities, followed by dynamic testing to validate the potential susceptibilities identified. A comprehensive examination of the source code revealed robust coding practices, with only a single high-severity finding in the extension identified. Although several hardening measures were identified throughout the testing process, the robust technology stack and architecture effectively mitigate multiple vulnerabilities, thereby allowing for an extended timeline for issue resolution.

Community Labs demonstrated a strong commitment to addressing the identified issues, successfully resolving all five findings, inclusive of informational findings, within two weeks of the initial report delivery. During the above-mentioned period, the team identified a total of 5 issues in the following risk categories:

  • Critical Risk: 0
  • High Risk: 1
  • Moderate Risk: 1
  • Low Risk: 0
  • Informational: 3

Cantina’s Experience with Open Security

The Cantina team had a positive experience working with Open Security. The Open Security team was professional and communicative and ensured that they were aligned with the client’s goals and desired results. The Open Security team provided comprehensive updates to the Community Labs team and was very keen on ensuring that support after the engagement was thorough and responsive.

The Open Security team did an excellent job in providing mitigation recommendations as well as continuing to dive into vulnerabilities identified after the review had already been completed. We want to recognize Open Security for going the extra mile and attest to their commitment to quality traditional security services.

The clarity of Open Security's reports set them apart. Each identified vulnerability was comprehensively detailed yet articulated in a manner that is clearly understood, irrespective of technical proficiency. The true distinction, however, lay in the interactive discussions and walkthroughs with the Community Labs team; the collaborative spirit between Cantina and Open Security was most evident during remediation efforts. Traditionally, the process involves stages – from report review to planning and then to the execution of mitigation strategies. Due to changes in client rollout timelines, Open Security’s tailored their standard approach, empowering client remediation to happen in tandem with the reporting process.

In retrospect, Open Security wasn't just an external reviewer for us; they’ve emerged as strong partners in securing our clients’ infrastructure and we are excited for continuing to engage with them in the future.
