It’s possible the “mystery” they refer to could be related to the identity of the hacker(s), how it got onto the routers in the first place, or the purpose for the attack

"mystery malware"

The article clarifies the name of the malware.

Clickbait BS. Why are you being disingenuous?

[-] subtext@lemmy.world 10 points 7 months ago

Your reply reads to me as if you’re calling me disingenuous, which I can’t for the life of me understand. I’m not the author. I offered a possible explanation.

As someone who works with 100Gbps networking:

why the heck do these routers run Lua of all things???

[-] Max_P@lemmy.max-p.me 9 points 7 months ago

OpenWRT uses Lua for its web UI. The interpreter can be really small which works well for tiny embedded devices with mere megabytes of storage, and it's much safer than writing a web GUI entirely in C.

[-] stardreamer@lemmy.blahaj.zone 2 points 7 months ago

Yeah I completely forgot about the consumer side of things. I was expecting there being Cisco iOS/FRR router configs, not a full web dashboard.

[-] redcalcium@lemmy.institute 2 points 7 months ago

I imagine the malware binary includes a lua interpreter for executing scripts fetched from its command and control server.

One day last October, subscribers to an ISP known as Windstream

In case anyone only reads the headline

[-] KaRunChiy@kbin.run 26 points 7 months ago

Oh shit, I use Windstream, this explains a lot about why they were so busy replacing everyones routers down here. I had assumed it was just a defective design since they used all the same units for every network, but it was actually malware, wild

the sad thing is this is just routers, think about all of the IoT devices that are compromised due to vendors not caring about patching security issues, just worrying about selling IoT.

[-] SlopppyEngineer@lemmy.world 5 points 7 months ago

insecam.org for a quick demo of insecure devices

Shodan also has a lot of fun searches.

[-] BearOfaTime@lemm.ee 3 points 7 months ago

Or having non existent security

[-] Cosmicomical@lemmy.world 13 points 7 months ago

Keep firing tech people, the tech peiple will have to find an hobby

[-] gravitas_deficiency@sh.itjust.works 10 points 7 months ago

And that’s why you should run your own router. Preferably using open firmware/OS like ddwrt or pfSense/opnSense.

[-] robotica@lemmy.world 2 points 7 months ago

I'm curious, does running open source software somehow exempt you from getting malware?

[-] gravitas_deficiency@sh.itjust.works 12 points 7 months ago

Not necessarily, but the odds of getting popped by a heretofore undisclosed backdoor that your ISP didn’t think would be a big deal are eliminated entirely, and you can also do a lot more interesting things with your home infrastructure, if that’s your thing.

[-] cmnybo@discuss.tchncs.de 9 points 7 months ago

You also get regular updates with open source firmware. Many of the ISP provided routers will never see an update.

[-] Max_P@lemmy.max-p.me 5 points 7 months ago

It also doesn't ship with ISP backdoors or ISP remote management crap that can be a big attack vector. Just about every ISP router I've looked at has some hardcoded super admin password or secret unauthenticated paths to access hidden settings.

Custom firmware ships with plain web UI and/or SSH only from the LAN side (or even specific VLAN), so right off the start there isn't a whole lot of potentially exploitable surface. And the community actually cares.

[-] robotica@lemmy.world 1 points 7 months ago* (last edited 7 months ago)

Is the recent XZ backdoor (and something that had to do with SSH too) anything to worry about in terms of the probability of there being a backdoor even in open source router software?

Not trying to dissuade anyone here, I love open source software, I'm just wondering how much effort is reasonable to be put into securing your local network (i.e. buying your own router, also installing open source software, or writing your own router software if you don't trust existing solutions) given that not everyone is tech savvy and you get diminishing returns for every additional security measure. And when is the usual point at which you would say "okay, this is secure enough"?

My router is not from an ISP, but it does get frequent firmware updates and I don't use any cloud management features, only local configuration.

[-] gravitas_deficiency@sh.itjust.works 0 points 7 months ago

I mean, the ISP-provided boxes don’t give you a way to upgrade past that faster than you would on an open distribution. The latter had fixes out within a week, or just weren’t affected. And it’s also way easier to check the deps on open firmware/OSes.
