Analogy/Comparison
Imagine a police officer stopping a gang of burglars from using certain roads to get to people’s houses. Cloudflare did something similar by blocking the internet addresses that the Aisuru botnet was using to commit cybercrimes.
Why It Matters
This matters because botnets like Aisuru try to break into people’s online accounts by guessing their passwords. Cloudflare’s action helps protect many internet users from having their accounts stolen or misused. For example, Cloudflare noticed “tens of millions” of requests per minute trying to access certain websites, which showed the botnet was very active and dangerous.
