Every two weeks, tune in to listen to the experts that make up our company.

Since 2017, Amber Group has been working hard to provide high-quality services to our clients, from small to expert investors, and ensure security, transparency, and profitability through our digital asset platform WhaleFin.

The secret? Experts, professionals, and veterans of the blockchain industry as well as of the traditional financial sector that can delve into the cogs of a promising yet complex technology that is reshaping our present, i.e., distributed ledger technology, while also understanding how to plug it into the existing financial structure.

This interview is a bite-sized deep-dive into our security efforts, expounded upon by none other than our Head of Blockchain Security, Dr. Chiachih Wu (@chiachih_wu on Twitter).

As the head of the team, Chiachih boasts extensive experience in the cybersecurity sector, covering certifications and training spanning Computational Applied Logic, Computer and Network Security, and Design and Analysis of Algorithms, among others.

Follow us on Twitter @whalefinapp to stay abreast of our updates, and the upcoming WhaleFin Beneath the Surface videos.

Amber Group’s security team ranked 6 out of 445 at the Paradigm CTF Hacking competition, the world cup of Web3 security. What does it consist of? 03:45–05:59

Paradigm CTF is one of the most challenging Web3-focused security competitions — amazing for blockchain security folks, this competition consists of challenges created by some of the brightest minds in the field. The blockchain security team at Amber Group, led by Chiachih, participated as team Amber_Labs and ranked #6 from a total of 445 teams.

Are security hacks a long-term issue for crypto security? 06:00–07:14

The industry will evolve, and improve. What we are experiencing is the beginnings of the blockchain and Web3 industry, and as such, devs should hire security experts, but there is also strong development going on with automated tools to ensure and implement security protocols.

Are cross-chain bridges one of the weakest points for blockchain security? Is it harming the multi-chain narrative? 07:15–08:30

Bridges are indeed a weak point because they need to process info from multiple chains, and that opening presents a vulnerability that at times can be more easily breached by hackers and exploiters. Nonetheless, our knowledge of security and defending these vulnerabilities is also improving, thus empowering us with more tools to prevent and foresee exploits, and insulate from the consequences.

Take the Wintermute hack, for example.

What are the red flags to look for to evaluate new projects from a security standpoint? 08:40–09:57

Reading the project’s whitepaper, reviewing the protocol’s public posts, social media and github, learning more about the team and the experience and career trajectory of the founder(s) should all be factored in when assessing the value of a new project.

Should I use a custodian or self-custody? What is the difference? 09:58–11:21

The average person may benefit from using a custodian due to the complexity of current tools that exist to interact with crypto. For those that choose to self-custody, it’s very important to understand all security best practices, back up everything, use a “cold” hardware wallet, and secure the device that you use.

Watch our video to better understand the difference and the implications of using hot vs. cold wallets.

How does WhaleFin secure the assets of its users? 11:22–12:32

At Amber and WhaleFin we use MPC and HSM solutions to prevent single-points of failure with professional security teams to deploy those systems with certificates such as SOC II, ISO 2701 and others. Additionally, we have solid contingency plans in place for anything unexpected. Security and our track record is one of our core value propositions as a company and as a service provider.
