Why Cryptocurrency Exchanges Need Audits
Rising Threats in Crypto
- Over $7.6 billion stolen since 2011 (CoinDesk, 2020).
- Four major exchange hacks reported in 2021 alone.
Client’s Challenge
A crypto exchange sought an external audit three weeks before launch to:
- Perform white-box penetration testing.
- Conduct in-depth code reviews.
- Prioritize fixes for critical vulnerabilities.
Audit Methodology
Simplified Workflow
Rapid Risk Assessment:
- Cross-border collaboration (Japan/Vietnam teams).
- Critical vulnerabilities prioritized.
Post-Launch Safeguards:
- Continuous security monitoring.
- Pre-release audits for future updates.
Critical Findings
Tokyo Tech Lab identified 30+ security issues, including:
| Vulnerability | Risk Level |
|--------------|-----------|
| Weak admin controls | Critical |
| Missing API access restrictions | Major |
| Outdated software (Apache, PHP, Laravel) | High |
| Inadequate rate limiting | Medium |
Notable Risks
- API Exploits: Unrestricted access allowed user data manipulation.
- Outdated Software: Older versions of OpenSSL/jQuery posed compliance risks.
