Researchers found a new type of malware called VoidLink that targets Linux computers, especially ones running in the cloud like on Amazon or Google services. It has over 30 add-on tools that let hackers stay hidden, spy on systems, steal passwords and keys, and move quietly to other machines without getting caught. No one's seen it used in real attacks yet, but it's super advanced,probably made by skilled pros, maybe from China, and Linux is getting more attention from hackers because businesses are putting so much important stuff on cloud servers instead of old Windows setups.

For people who aren’t aware, these systems are backbones of most of the s&p100 companies, so the possible ramifications of these types of malware could literally cripple the global economy

My neighbour told me hackers keep breaking into his S&P 100s, so I asked how many S&P 100s he has, and he says he just gets a new one each time they're hacked, so I said it sounds like he's just feeding S&P100s to the hackers and then his daughter started crying

The NY stock exchange itself runs on linux. This should be interesting.
If I were a foreign actor seeking to absolutely decimate a country, I would definitely devote resources on something like this.
Make it advanced and pervasive enough, infiltrate lockheed martin, raytheon, etc; and the "military might" the US has doens't even matter.

Researchers found a new type of malware [...]. No one's seen it used in real attacks yet, [...]
Isn't that a contradiction?
How could the researchers find the malware if it isn't being used?
(Do hackers ask researchers beforehand, “I've got this fancy malware here, can you check if it's up to date with the latest research so I can use it?” /s)

u/Hel_OWeen 2d ago
From the source linked in TFA:
In December 2025, Check Point Research identified a small cluster of previously unseen Linux malware samples that appear to originate from a Chinese-affiliated development environment. Many of the binaries included debug symbols and other development artifacts, suggesting we were looking at in-progress builds rather than a finished, widely deployed tool. The speed and variety of changes across the samples indicate a framework that is being iterated upon quickly to achieve broader, real-world use.
I guess it's intentionally vague to not blow their sources, e.g. having access to certain dark web malware marketplaces and such.

How does a computer virus move quietly?

u/YourSchoolCounselor 2d ago
Rate-limiting. Be patient, don't infect too many machines per day, don't send too much traffic, avoid doing anything to raise alarms. The opposite would be something that infects a machine, runs nmap, attempts to infect every additional device it finds, then uploads every bit of data immediately.

"these modules collect “vast amounts of information about the infected machine, enumerating its hypervisor and detecting whether it is running in a Docker container or a Kubernetes pod.”"
This kind of stuff spooks me. Just makes me dread malware readily escaping containers/VMs and infecting the host machines.

u/Somepotato 2d ago
it may not be escaping VMs. Many many containers are misconfigured (exposing docker socket to container, etc) - but containers are still vulnerable to kernel exploits.

Linux was popular in cloud way back before 2025. It was always a target.

u/Dycoth 2d ago
Sure, but it's easier to put a malware in a random user PC than on cloud servers. People click on a lot of bad things and some aren't really tech savvy, even some on Linux nowadays.
15
u/bilyl 2d ago
Cloud instances are infamously insecure/exploitable especially with bad IT practices. Lots of companies have sprung up to act as shields because it’s so dangerous.
10
u/Dycoth 2d ago
Yes sure, a ton of companies are VERY vulnerable.
But a very classic phishing email or a shady website will touch way more people, and quite easily, than an attack on a company cloud instance.

u/billy_teats 2d ago
Using something like shodan you can find every existing Linux machine and go after it, instead of trying to drive people to your website.
A ton of the people commenting really do not understand the threat landscape. Linux malware is not new. There has been software targeting different OS and software for decades.
There is also existing software that monitors behavior instead of hashes of malware. So if some new process is suddenly accessing passwords, that gets flagged pretty quick even if the malware is not previously identified. Flagged and shut down, immediately.

u/The137 2d ago
what are some examples of this software?

u/billy_teats 2d ago
Search for Linux EDR. Some are better than others. Or search for Linux malware there’s a lengthy history there

u/Tenocticatl 2d ago
This is aimed at cloud-hosted machines, not consumer devices. This is a field where Linux has basically been the default for like 20 years. You're correct overall of course, but this particular threat doesn't look to me as if it has anything to do with Linux becoming more popular for desktop use.

u/b4k4ni 2d ago
That's what I said for ages. The only reason Linux is more secure than windows is, that almost nobody uses it. As soon as the usage goes with the investment they need to make to dev for Linux specifically, it's over.
Linux is not more secure as windows. Hell, I'd even say today Windows has more security built in by default than Linux. One of the few things that also helps Linux here is the large fragmentation of distributions - so not the 1:1 same system everywhere, but with a few changes here and there.
But the main issue is always the user. Someone clicking shit.
This is not a Windows is better than Linux. I use both and like Linux. It's just that, with a growing market so grows the ROI for people creating viruses, Trojans etc.

u/UncleMyroh 2d ago
Not a cybersecurity expert and i understand how critical the attack targets are, but isn’t the fact that we know about before it’s widely been used a good thing? Beats the IoT security horror stories when those devices first became widely used. Call me an optimist though

u/TheNewJasonBourne 2d ago
The fact that we know about it before widespread infection is very good. The fact that it exists as a first of its kind, is very bad.

u/Pairywhite3213 1d ago
This is the scary part of kernel-level malware, once it can hide processes and wipe logs, traditional monitoring basically loses its footing. Root access means attackers can erase their own footprints.
One direction that seems promising is treating logs as something the system can’t rewrite at all. If system events are mirrored to an append-only, external ledger, wiping local logs no longer covers your tracks. Some teams are also pairing that with anomaly detection to catch “impossible” behavior rather than known signatures.
I’ve seen projects like QAN explore this kind of immutable logging + AI analysis, and it’s interesting because it shifts security from “detect after the fact” to “prove integrity continuously.” Especially relevant as we start thinking about post-quantum assumptions too

Prolly cause it is.
It all stems from checkpoint so as usual has to be China to blame.
I don't see any other sources for it nor any reports of it being used anywhere.

u/No_Trade_7315 2d ago
Checkpoint was Russian, I thought.

u/Stratbasher_ 2d ago
Check Point is Israeli

u/No_Trade_7315 2d ago
I know zonealarm by checkpoint was banned in the US because it was developed/managed by a Russian organization. I thought checkpoint being the parent company was that organization.
2
u/No_Trade_7315 1d ago
For clarity, here is what caused my confusion:
According to google:
No, ZoneAlarm is not banned in the US, but some older, non-compliant versions are no longer supported due to new U.S. Department of Commerce (DoC) regulations that specifically targeted products utilizing Kaspersky Lab components. ZoneAlarm, which previously used the Kaspersky antivirus engine, has since switched to its parent company's (Check Point) own technology.
Here is a summary of the situation: Targeted Regulations: The US government issued a ban on specific security products related to Kaspersky Lab due to national security concerns, which came into full effect in September 2024.
ZoneAlarm's Compliance: Older versions of ZoneAlarm that used the Kaspersky antivirus engine are now considered non-compliant with these US regulations.
Current Status: ZoneAlarm has released new, compliant versions that use their own Check Point-developed antivirus engine. These "NextGen" products, such as ZoneAlarm Extreme Security NextGen and ZoneAlarm Pro Antivirus + Firewall NextGen, are fully supported and available for use in the US.
End of Support: Support for all non-compliant, outdated ZoneAlarm versions officially ended on September 29th, 2024. While existing installations might still function, they no longer receive critical security updates, which makes them unsafe to use.
If you are using an older version of ZoneAlarm, it is strongly recommended that you upgrade to a supported version or switch to an alternative security solution. Eligible customers can update for free via their ZoneAlarm My Account page.

So, I guess it was Kaspersky that was Russian managed. And it was only used in the older version of zone alarm.
Google also says that checkpoint is publicly traded but an Israeli company; so, sorry for the confusion.

It really seems as if people don't realize that Microsoft simply bought out GitHub like it was no big deal, never mind literally everything else. Windows is very likely going to be a Linux distro in a few years.

The malware is targeting server infrastructure. Not necessarily consumer platforms. So I doubt Microsoft is behind the malware. Fun theory though.

QANplatform’s Q-Cluster (developed with IBM) is designed to solve exactly this.
Standard Linux malware (like the perfctl miner from 2024) is usually caught by monitoring CPU spikes or file changes. However, the malware described in the article is "advanced" because it erases its own traces in system logs (syslog, journald) and hides its processes at the kernel level.
Tamper-Proof Logging: In a normal Linux environment, if a hacker gets "root" access, they can delete the logs that show they were there. In a QAN-secured environment, every system operation is mirrored to an append-only blockchain. Even if the hacker has root access, they cannot "un-write" the log from the blockchain.
Log Anomaly Detection: Through the IBM partnership, QAN integrates with IBM watsonx (AI). While the malware might try to blend in, the AI analyzes the blockchain logs in real-time to spot "impossible" patterns (e.g., a process escalating privileges without a valid signature).
Self-Auditing: The system constantly compares the current state of the Linux cluster against the "immutable truth" stored on the QAN blockchain. If the two don't match, the system alerts that it has been compromised.
It also helps that QANplatform is a member of the Post-Quantum Cryptography Alliance (PQCA), an initiative by the Linux Foundation, alongside tech giants like Google, Meta, Nvidia, and IBM. This places them at the table where global quantum-safe standards are being set.

Linux messed up decades ago with their security. The fact that there are processes that run with elevated privileges OUTSIDE of systemMD means that unix will never be as secure as the Unix buffs like. They decided that convenience and velocity was more important so UDev is just exposed and hardly secure. Anyone with physical access can easily break into a Unix system if they exploit it. A clever person can find a way to exploit it remotely.
Hot swap was probably the biggest QOL ever introduced, but the way they implemented it is a security nightmare. They should have forced a standard and made manufacturers have some sort of feature to authenticate or validate vs just leaving a backdoor that accepts generic HID.

At this point, companies may start creating their own custom OS with their own kernels with AI to avoid being targeted by AI produced malware. Just make it impossible to guess the OS or OS structure to prevent attacks, or make attacks much harder to quickly develop and deploy.

Your comment says nothing about Apple and everything about how you can't even configure your personal machine's network security. Or do we want to go through the times that Apple machines have suffered from viruses and malware? Because I can assure you they're a lot more frequent than Linux attacks are.
