Cloudflare Crushes Record 29.7 Tbps DDoS Attack – Biggest Ever!
Cloudflare just blocked the largest DDoS attack in history, clocking in at a staggering 29.7 terabits per second. This monster came from a botnet-for-hire called AISURU, which has been lobbing hyper-volumetric assaults all year.
The Details
The attack hit like a digital tsunami, overwhelming targets with sheer volume. Cloudflare’s systems detected and shredded it before it could cause real damage. AISURU isn’t new – it’s tied to a string of massive DDoS campaigns, renting out its firepower to anyone with grudges or crypto to burn. This one dwarfs previous records, showing how botnets are scaling up with hijacked IoT devices and cloud resources. No specific victims named yet, but the sheer size means it targeted high-profile sites or services.
So What?
Developers, this is your wake-up call: DDoS isn’t just “someone else’s problem” anymore. If you’re building web apps, APIs, or anything internet-facing, assume you’re next. Basic rate limiting won’t cut it against Tbps-scale floods – you need CDN-level mitigation like Cloudflare or Akamai baked in from day one. Check your stack for unpatched IoT vulns or weak cloud configs that botnets love. And test your failover: one outage can tank your rep and revenue.
Final Take
Scale of attacks like this proves the arms race never stops. Patch fast, layer defenses, and don’t skimp on traffic scrubbing – or get ready to watch your site crumble under the weight.
