New 0-Day Attacks Linked to China's 'Volt Typhoon'

If ISPs are leaving management ports open on the Internet, it's going to take more than a vendor patch to protect them from cyber warfare.

It's like leaving a BMC open to the internet: these things are built with no security in mind, and can be rooted as soon as they can be connected to.
This is what you get when there's no checklist enforced. I would like to see all those people pour into the conversation jumping up and down with glee that their plan worked.
I don't think this aligns with the reality of modern IT. Even with high competence and good intentions, it's an organizational problem and mistakes are easy.
We need better checklists, I guess.
You really need better defaults (“all ports start closed”) and a culture of strong justification for any changes from the known safe defaults.
This is of course at odds with convenience so it probably won’t happen.
The problem with that, however, is that vulnerabilites are constantly discovered, and what is safe today is not safe tomorrow. Electrical safety and fire resistance is much more permanent: if it's done right, it's likely to be safe for a long time.
Vendors just find it too difficult to certify against attacks at the “script kiddie” level, so they lobbied the government to lower the standards so even the lowest rated systems, ones not even audited for security, are allowed for general usage in critical systems.
The large commercial vendors, such as Apple, Microsoft, or Amazon, have spent billions of dollars and literal decades trying to improve their security and have uniformly failed to certify that they can deploy any system that can protect against small commercial teams unlike actual high security vendors who can produce systems secure against even state actors.
But you can, as an organization, choose to follow one and be "Secure by default", with exceptions e.g. "Open a port other than 443 to the Internet" being understood and risk managed.
It will slow down developers, for sure. But everything's a tradeoff.
You can find hundreds of upvotes for checklists. The same sort of institutionally-decreed checklists. For every admin that lets compromised passwords linger there's one that can closes his port and vice-versa.
It's a cultural resentment of being forced to do the simple things. You dont honestly think a doctor needs to be told how to prep for surgery. But the doctor has and follows a checklist. You don't honestly think a pilot needs to be told how to prep for departure, but the pilot follows a checklist
Watching "modern IT" people demand special treatment because "modern IT" is just built different than modern flying or modern surgery is watching the height of arrogance.
Not really. In > 99.99% of software projects, the risk of an error leading to people dying is lower than it is for a surgeon or a air traffic controller.
Additionally, software is an extremely broad tool, like mathematics, that can be applied to nearly any domain. Consequently, slowing down devs via regulation as you suggest will also slow both technological progress and economic growth. In a few circumstances, the risk may be enough to justify that cost, but it there’s high bar to clear.
Based on my observation of fellow Chinese software engineers' average knowledge and skills about cyber security, as well as the absolute absent of security considerations of most "SOHO network devices" in China, I would rather apply Hanlon's razor and say that it's not the Chinese attackers, but it's Chinese botnet.
As you may already know, Chinese users and software engineers generally does not care about personal privacy and hence also cyber security, so the entire industry is rather undeveloped.
If you read the CVE description linked you'll notice some details focused on the actual specific product, I have a hard time believing random hackers trying to build a botnet would search out critical infrastructure and burn expensive 0-days for small amounts of compute.
I may be wrong, but I think the development of an "industry" would depend on the foundation of related education and its popularity in the population. Like if football is not taught in the school and people generally don't play it in a country, it's unlikely to have a team to win in olympics even if the government wants it.

> Black Lotus Labs said it assessed with “medium” confidence that Volt Typhoon was responsible for the compromises, noting the intrusions bear the hallmarks of the Chinese state-sponsored espionage group — including zero-day attacks targeting IT infrastructure providers, and Java-based backdoors that run in memory only.
Who is Natto Thoughts and why should I care? Substack opinions are cheap.
Analogy: "was this murder committed by Jack the Ripper?" and "who was Jack the Ripper?" are separate questions.

I am curious why doesn't Versa use the exploit themselves to patch the issue? it would be a great wake up moment to realize that stuff is not secure as it should be with updates.
Liability - when you do not have the monopoly on violence, you don't set the rules.

(a low blow I know)
Here in Paraguay we have an ISP using it for their enterprise secure SD-WAN offering. I know it is deployed in Colombia also by the same ISP. So, it is used, although widely i do not know.
It is similar to FortiManager, Aruba Central, and the like.
well there's a sentence to think about in horror
