Cloudflare Finally Pulls Its Head Out and Boots the Aisuru Botnet Off the “Top Domains” List

Oh bloody hell, look who finally decided to clean up their bloody mess — Cloudflare. Turns out some smart bastards noticed that their “Top Domains” list, the shiny public display of supposedly legit traffic, had a fair few filthy freeloaders squatting in it. And by freeloaders, I mean domains being run by the goddamn Aisuru botnet — a network of hijacked IoT crap and PCs busy committing Internet war crimes while sipping digital piña coladas on Cloudflare’s infrastructure.

So, after Brian Krebs waves his big “look at this shit” flag, Cloudflare wakes up from their corporate nap, realises they’ve been hosting cyber-scum, and purges the damn list. The Aisuru botnet operators were apparently using Cloudflare to hide their grubby command-and-control servers behind nice, shiny Cloudflare front ends — because of course they were. That’s what happens when you’re the biggest bloody CDN on the planet: every hacker and their mum wants to use you as their personal invisibility cloak.

Cloudflare, acting all shocked, swore up and down that they don’t *actually* make money off botnets — which is cute — and then said they’d update their verification process to make sure their top list isn’t just a roll call of criminal cockroaches. It’s like cleaning the toilets only after someone complains about the stench — too little, too late, but at least no one’s puking anymore.

And there you go — another episode of “Tech Giants Pretend They Didn’t Know,” starring Cloudflare as the clueless landlord of Botnet Towers. Maybe next week, Google will realise half of YouTube’s “live streams” are cryptomining malware in disguise. Stay tuned.

Reminds me of the time I caught a dev piping production logs through a personal Dropbox. When I asked why, he said, “Because it’s convenient.” So was deleting his account. Bastard.
