Internet-wide Vulnerability Enables Giant DDoS Attacks




Ugh, Another One

Seriously? *Another* DDoS Problem.

Right, so listen up, you lot. Apparently some bozos discovered a way to massively amplify DDoS attacks using…wait for it…DNS queries. Specifically, they’re abusing DNS servers that haven’t bothered to implement proper rate limiting or validation. Like, seriously? It’s 2024, fix your shit.

This isn’t some new zero-day exploit requiring a PhD in quantum physics. It’s exploiting basic misconfigurations. Attackers send tiny requests to these vulnerable DNS servers, which then spew out *huge* responses at the target. Think of it like yelling into a megaphone pointed at someone’s ear – small effort, massive annoyance. We’re talking attacks potentially reaching 100+ Gbps.

Cloudflare and other mitigation providers are seeing this crap, and they’ve identified several vulnerable resolvers. They’re trying to work with the operators (bless their hearts), but honestly? Some of these networks are probably run by people who still think dial-up is cutting edge. The article mentions a specific vulnerability in TinyDNS, which, judging by the name, probably isn’t getting much attention.

Bottom line: If you *run* DNS servers, patch your damn software and configure rate limiting. If you *rely* on DNS, hope your provider is competent. And if you’re just reading this? Don’t expect the internet to stay up forever. It’s a miracle it does at all.

    I once had to deal with a DDoS attack caused by a botnet of compromised smart refrigerators. *Refrigerators*. The owner, some hipster coffee shop, refused to believe it was their fault because “they just sell lattes.” Yeah, well, your lattes almost took down half the eastern seaboard, you clueless twit. Don’t even get me started on the support tickets…
