Hackers use shared CDNs to hide traffic behind trusted domains
Hackers are exploiting a vulnerability in shared Content Delivery Network (CDN) infrastructure to conceal malicious traffic. This abuse allows them to bypass domain reputation security controls by hiding their activities behind trusted domains. The core issue lies within how shared CDN environments handle diverse user traffic.
Key Takeaways
- Attackers are hiding malicious traffic behind trusted, high-reputation domains on shared CDN infrastructure.
- The abuse specifically targets domain reputation security controls.
- The core issue is how shared CDN environments handle traffic from diverse users.
Why It Matters
This means domain reputation checks can be bypassed when malicious traffic is embedded in shared CDN traffic, reducing the value of a control many security teams rely on. The article ties the problem to the structure of shared content delivery networks, where diverse user traffic is handled through the same infrastructure. For streaming and delivery stacks, that puts more scrutiny on how CDN traffic is classified and inspected. Watch for follow-up reporting on which shared CDN environments are being abused and whether vendors change how they handle mixed-tenant traffic.
