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:

• s-dfgfd-sdfz...zdssragv[.]mom
• 96bccebb2f7e...wu7y6z[.]com
• 60r...60pg0131[.]cc
• and billions of similar ones...

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.
