⚔️ OpenBLD.net — Algorithm (zBLD) vs. Algorithm (DGA)
· 2 min read
Malware and botnets use DGA (Domain Generation Algorithm)—algorithms that generate hundreds of "trash" domains per second to communicate with C2 servers.
An attack example from real OpenBLD logs:

What's the harm?
Aside from the obvious malicious intent, this chaotic spam clogs the cache, hammers I/O, chews up CPU time, and generates gigabytes of junk logs. As a result—speed degradation and high resource utilization.
