Why Fast Flux Is Harder to Detect in CDN and Cloud-Based Setups?
DNS Fast Flux rapidly changes the IP addresses (and even the DNS servers) for a malicious domain, as shown above. Attackers often use compromised machines as proxies, cycling through “hundreds or even thousands” of IP addresses with very low DNS TTL (sometimes as short as 60 seconds). This means each DNS query can return a……

Real-World Cyber Attack Detection: How Modern SOCs Identify, Block, and Contain Advanced Threats
Executive Summary Modern cyberattacks rarely appear as a single, obvious incident. Instead, they manifest as multiple low-level signals across web, endpoint, DNS, cloud, and network telemetry. When analyzed in isolation, these signals may seem benign. When correlated intelligently, they reveal active attack campaigns targeting applications, identities, cloud storage, and network boundaries. This article presents a…
