Luckily I sit right next to my home server and can hear when the fans kick in under load. The absence of noise tells me I don’t have this problem :)
Mine is ultra low voltage and I barely maintain it so this article gave me a bit of a scare. I’ll probably wipe it by the next reinstall anyway since it’s been nearly 10 years of Ubuntu LTS upgrades and it’s a mess (both what I’ve done to it and what Ubuntu has done to itself).
Thousands!? Shit. That’s like all of them!
Shouldn’t be this hard to find out the attack vector.
Buried deep, deep in their writeup:
RocketMQ servers
- CVE-2021-4043 (Polkit)
- CVE-2023-33246
I’m sure if you’re running other insecure, public facing web servers with bad configs, the actor could exploit that too, but they didn’t provide any evidence of this happening in the wild (no threat group TTPs for initial access), so pure FUD to try to sell their security product.
Unfortunately, Ars mostly just restated verbatim what was provided by the security vendor Aqua Nautilus.
There’s also a buried reference to using a several-years-patched gpac bug to gain root access before this thing can do most of its stealth stuff.
Basically, it needs your system to already have a known, unpatched RCE bug before it can get a foothold, and if you’ve got one of those you have problems that go way beyond stealth crypto miners stealing electricity.
This story reeks of FUD.
exploiting more than 20,000 common misconfigurations, a capability that may make millions of machines connected to the Internet potential targets,
Because a “common misconfiguration” will absolutely make your system vulnerable!?!
OK show just ONE!This is FUD to either prevent people from using Linux, or simply a hoax to get attention, or maybe to make you think you need additional security software.
what does FUD stand for?
Fear, uncertainty and doubt
Crowd strike looking for a new market?
Unfortunately they are already in the market and making a mess: https://www.theregister.com/2024/07/21/crowdstrike_linux_crashes_restoration_tools/
ssh with an easy to guess root password?
Wouldn’t that simply be a user mistake?
It’s kind of like saying if you remove the password completely, it’s vulnerable.
Can’t be infected if I keep wiping my partition for a new shiny distro
Your install USB is infected by a rookit and reinstalls itself on connect.
Jokes on you, the rootkit is likely my own and I just forgot about it.
It’s tough being an ADHD Hacker
This was my first thought. I haven’t had the same os installed for a few months max, nevermind 3 years
Seeing the diagram, it only attacks servers with misconfigured rocketMQ or CVE-2023-33426, which is already patched. Am I understanding this correctly?
It probably has a large database of exploits it can use. The article claims 20k, but this seems to high for me.
Sounds like it should at least be noticeable if you monitor resource usage?
That’s how some people found it, but it would disappear when someone would login to investigate.
Sure, but it’s still fairly detectable when it’s on a server at least, as long as you have monitoring. Just a bitch to pinpoint and fix.
Yes, but they replace common tools like top or lsof with manipulated versions. This might at least trick less experienced sysadmins.
Edit: Some found out about the vulnerability by ressource alerts. Probably very easy in a virtualized environment. The malware can’t fool the hypervisor ;)
Not quite the monitoring I’m talking about though.
Basically, it seems like this would be a nightmare for a home user to detect, but a company is probably gonna pick up on this quite quickly with snmp monitoring (unless it somehow does something to that).
Vulnerable to 20,000 misconfigurations, But thearted by 42 billion different simple checks that we all do anyway.
5 minute load greater than 80% of the number of cores? That’s an alarm…
Millions of systems shut down by dumb microsoft os.
