In this episode of Unchained, Mudit Gupta, Chief Information Security Officer at Polygon, delves into the security oversights that led to a significant breach at Safe. With a focus on security architecture and operational protocols, Gupta provides a critical analysis of the incident, offering insights into how such vulnerabilities can be mitigated in the future.
1. Security Architecture Flaws
- "It showed the poor level of security architecture or afterthought they had for the product. First of all, no single developer should have had access to push to production."
- Safe's security architecture was fundamentally flawed, allowing a single developer to push changes to production without oversight, which is a critical vulnerability.
- Gupta emphasizes the importance of multi-person verification for production changes, a policy followed at Polygon, to prevent unauthorized access and modifications.
- The breach highlights the need for robust security protocols, especially for critical systems like Safe, where a single point of failure can lead to significant consequences.
2. Lack of Monitoring and Alerting
- "This change happened on 19th February, but Safe had no monitoring or alerting around changes, and it went unnoticed for two days."
- Safe's failure to implement effective monitoring and alerting systems allowed the breach to go undetected for two days, exacerbating the impact.
- Gupta points out that timely detection through monitoring could have mitigated the breach's effects, potentially saving Bybit from being compromised.
- The incident underscores the necessity of real-time monitoring and alerting mechanisms to quickly identify and respond to unauthorized changes.
3. The Threat of Advanced Persistent Threats
- "I can't blame the developer for being compromised. If Lazarus wants to compromise you or me, they will."
- Gupta acknowledges the formidable threat posed by advanced persistent threats like Lazarus, which can compromise individuals despite strong personal security measures.
- The discussion highlights the importance of designing systems that do not rely on the security of a single individual, as even the most secure individuals can be targeted and compromised.
- Organizations must assume that individuals can be compromised and design their security architecture to minimize the impact of such events.
Key Takeaways:
- Robust security architecture is crucial to prevent unauthorized access and modifications, especially in critical systems.
- Effective monitoring and alerting systems are essential for timely detection and response to security breaches.
- Security protocols should be designed to minimize reliance on individual security, acknowledging the threat of advanced persistent threats.
Actionable Insights:
- Implement multi-person verification for all production changes to enhance security.
- Establish real-time monitoring and alerting systems to detect unauthorized changes promptly.
- Design security systems that assume individuals can be compromised, reducing reliance on personal security.
