Dysphoria Botnet Bloats to 200,000 Devices Because Apparently Securing Shit Is Too Hard
Right then, here’s the miserable state of affairs: a DDoS botnet called Dysphoria has managed to spread to roughly 200,000 compromised devices worldwide, because of course it has. The internet remains a landfill of badly secured gear, default passwords, neglected updates, and administrators who apparently think “I’ll do it later” is a security strategy. Spoiler: it bloody well isn’t.
According to the report, Dysphoria is targeting routers, IoT devices, and various Linux-based systems, hoovering them up into a botnet for distributed denial-of-service attacks. In other words, some festering little goblins found a mountain of vulnerable devices and turned them into a giant digital brick for smashing websites and services off the internet. Efficient, if you’re a complete bastard.
The malware appears to be notable for its multi-architecture support, which means it can infect a broad range of systems instead of limiting itself to one narrow slice of the usual garbage. That’s what happens when the people writing malware are motivated and the people defending networks are still using equipment old enough to vote. The campaign has reportedly spread across dozens of countries, because insecure devices are everyone’s problem now. How heartwarming.
The botnet’s operators are using it to launch high-volume DDoS attacks, and the malware has been observed exploiting exposed services and weakly protected systems. Amazing how the same lessons keep coming back like a bad smell: patch your bloody devices, change default credentials, lock down remote access, and stop exposing junk to the public internet unless you actually know what the hell you’re doing.
Researchers tracking the thing found that its growth has been alarmingly quick, which really just means there are far too many vulnerable devices sitting around doing sod-all except waiting to be recruited into criminal nonsense. Every cheap DVR, every forgotten router, every bargain-bin smart device with firmware maintained by a bloke in a shed becomes another tiny asshole in a giant attacking swarm. Splendid.
The practical takeaway, since apparently this still needs saying, is simple: inventory your internet-facing devices, update firmware, disable unnecessary remote admin features, enforce strong passwords, and monitor for weird traffic. If you don’t, some idiot with a botnet toolkit will do your systems management for you, and you won’t enjoy the results one fucking bit.
Anyway, this reminds me of the time someone insisted their mystery off-brand router was “secure enough” because the web interface had a login box. Two weeks later it was participating in an attack, the connection was slower than treacle, and they wanted me to fix it without replacing the device. I told them the router had achieved its highest purpose at last: becoming evidence in the case against cheap crap.
