Hackers can remotely destroy hundreds of thousands of solar systems across Europe, researchers find
Security researchers from the Chaos Computer Club (CCC) have exposed critical vulnerabilities in Hoymiles solar inverters that allow attackers to remotely control, manipulate, or destroy hundreds of thousands of solar installations across Europe. The Chinese manufacturer holds roughly 20 percent of the European microinverter market, making the security flaw a widespread threat to balcony power plants and small rooftop solar systems.
…
During experimental tests, a modified handheld scanner located two dozen foreign inverters and their identification numbers within 20 minutes. In Augsburg, Hunz identified 42 hackable systems within just one hour. The radio signals can travel several hundred meters, making it feasible to mount attack equipment on drones for systematic scanning of residential areas.
Once attackers have the serial numbers, they can switch inverters on or off, alter power limits, and inject malware through an unprotected firmware update command. Tampering with sensitive network parameters or erasing bootloader memory could lead to fires, electrical accidents, or device destruction requiring physical repair.
…
The CCC informed Hoymiles [which is headquartered in China] about the vulnerability in February but received no initial response. Only after the German Federal Office for Information Security contacted the Chinese authority CNCERT did Hoymiles react at the end of June. The company announced a security update for mid-October.

China Holds a Kill Switch to European Power Grids (May 2025)
Despite years of debate about supply chain resilience, more than 70 percent of world’s solar inverters come from Chinese manufacturers. The three biggest players – Huawei, Sungrow, and Ginlong Solis – are all Chinese. Here lies the first paradox: Huawei has been banned from a large portion of Europe’s 5G networks due to national security concerns, yet its technology is welcomed into the power grid.

A friend who will have to install a solar panel soon asked me to dig into that and I am horrified. This report is the tree that hides the forest as we say.
Sure, this specific inverter, which by the way has a circuit that’s used in many other brands, has a vulnerability that allows anyone to basically destroy the local electrical installation.
But the so-called secured systems are almost all cloud-based because people want to see on their phone their consumption. And the easiest way to do that is to go through a server that’s usually hosted by the manufacturer in mainland China. Many of these systems will include ways to change the firmware with the ability to do the same sort of damage that was demonstrated by the CCC.
For a while I didn’t like the tone of the news release warning in a vague way of bad or in Chinese products. It really sounded like FUD. But now I am realizing that the backdoor is real and public. All of these products are cloud-based, including firmware updates, which is an extremely bad idea.
That’s really a domain in which open hardware should be more the norm, should be pushed by states as a matter of sovereignty and national security.
And my personal advice would be to not wait for the state to do its job and be careful what you buy. Maybe prefer simpler, more observable hardware that costs a bit more than something that asks you to pair your phone and to give access to a remote server to your hardware that can burn your place down.
“The company announced a security update for mid-October.”
This is says it all, I doubt I will ever buy products from them.

Is this actually a problem? Sounds like china-scary fud.
It sounds like anyone can light your house on fire if you happened to buy this microinverter. Whether or not this is a consipiracy or shoddy workmanship.
I really don’t think it’s that easy. Nobody’s going to fly a drone down the street broadcasting malware to these inverters. Still sounds like FUD to me. “Don’t buy the reasonably priced solar, someone will burn your house down.”
The issue is can not will. One does not need a drone to do it either. The radios have a “several hundred meter range”. The device communicates without encryption, and accepts updates without encryption/authorization.
This applies to nearly all devices made by one company thats captured 1/5 of the market. It doesnt matter who makes it, this is unacceptable negligence.
This is an immently reasonable demand “The CCC is demanding mandatory minimum IT security standards for feed-in devices in the European Union. The organization specifically calls for banning devices that accept firmware updates via radio without cryptographic authentication.”
I have been arguing that for a long time because most articles failed to provide a brand, failed to provide the detail of the attack and basically were just fear-mongering for any Chinese product.
Here it is different, there is demonstrated attack by a reputable source, the CCC.
So now this information I consider got upgraded from probably FUD to probably real.
That’s a real actual problem. China gets a kill switch on a major source of renewable energy.
basically were just fear-mongering for any Chinese product.
China gets a kill switch on a major source of renewable energy.
Sounds like you’re fearmongering for a chinese product. Anyone within range could exploit the vulnerability.

Ok, we need to refer to them as something else. I thought we had a much bigger problem on our hands when I first read the title.
I read that same line 3 times before realizing this is not comic book villain bad.
This is some Men in Black shit I think
Frieza up in this bitch
Yeah, I was legit impressed both with the brazen threat of the hackers as well as Europe for somehow becoming a galaxy spanning union.
The stars on the flag aren’t stars, they’re actually galaxies!
Thought I was having a stroke reading the headline.
A brigade of yanks with “you just can’t understand how many solar systems fit in Texas, though” is incoming…
I didn’t realize Europe was its own galaxy
we’re self-centered enough for that lol
Every civilization ever has been self-centered, so honestly I’m not that torn up about it. Europe is more globally/internationally-focused than most of the world.
Why do you think it hosts the UN headquarters, ICC headquarters, and so many other IGO headquarters? It’s the only multi-national federation that I know of and is part of the largest and most widespread defense pact in the world.
Clearly people want to live there, otherwise they’d be migrating to BRICS nations and Northern Africa. So it must be doing something right.
What’s wrong with a civilization being self-centered? Especially when most of the critique it’s received regarding previous centuries was that it was too expansionist?
Because it retains a lot of soft power from the centuries of being the world power.
Depending on where you draw the line on what counts as federation vs other associations of countries, there are many potential others, like Mercosur, Gulf Cooperation Council, Caribbean Community, African Union.
I’d say this is irrelevant to the topic? Also a large part of the reason many people want to move to Europe is because Europe fucked up their home countries starting from the centuries of colonisation, resource extraction, arbitrarily redrawing borders that then fosters ethnic tension for generations, etc.
Well, Europeans tend to feel the world revolves around us (though the USA is even worse in this regard). We feel we can afford not to know about the history and geography of countries outside of Europe, since everything of import happened here. (Though in the post-WW2 era that consideration includes the USA.)
Also, I don’t think self-centredness and expansionism are opposites. If anything, self-centredness makes it more easy for people to disregard the rights and interests of the “others”, so exploiting them doesn’t feel as wrong as if it happened to other Europeans.
that’s bad, we’ll get a pretty bad reputation around the milky way
Already had one, why else do you think no one has contacted us yet? Wouldn’t you steer clear of this planet?
Mostly harmless.
I can’t wait for the day they decide to build a hyperspatial express highway through our star system
I assume so yes. The first video we transmitted was Hitler, and the biggest radio signals were H-bombs.
Thats some impressive reporting from a news org utilizing an AI stock image that has no apparent ties to the content. To be fair I can’t think of any obvious choices either.
I’ll just take a peek at their publishers:
Damn. 404. (not that one)
No worries - follow the money! Let’s see who your advertisers are…
404? The plot thickens.
About us! Surely they are going to describe their attention to detail, their quest for truth, and their refreshing lack of baises at this establishment…?
There can only be one explanation for this. Obviously.
The dangerous hacker known as En Jin X. This would have never happened if everyone needed their ID online!
Can confirm, About Us and Advertisers is Nginx 404 error, sus site.
It read like it was laser focused on pushing an idea while ignoring too many obvious parallels. The fact that the site is basically all facade - no function … kind of provides a physical representation of this entire movement. Its practically modern art.
That said - it really does drive home how this virtual snake oil is literally sending us in the wrong direction.
Did they break this story? Looks like this is a copy-paste article on hundreds of shitty sites: https://duckduckgo.com/?t=fpas&q=chaos+computer+club+solar+vulnerability+remote+chinese&ia=web
The Chaos Computer Club is real, and awesome, but I cand find anything on their site or YouTube about this yet. It was probably not in English though so thats on me: https://www.ccc.de/en/home
Edit, I just had to scroll down: https://lemmy.ca/post/67687895/24241020
I imagine the feat itself is possible and plausible - though I couldn’t speculate further without digging into the specifics.
What left me feeling wary was, at least in the US, theres been a massive push to limit the spread and use of renewables… and normally when sowing fear and doubt you generally want to tie in your preferred boogie man. Presently that would be China.
Misinformation campaigns and astro turfing frequently will rely on half truths as it is FAR easier to sow dissent in a community. A half truth becomes opinion - an easily disproven lie can backfire and unify communities.
Tons of Chinese equipment is exploitable. Most of the time its simply a product of “cheap, fast, stable/secure” pick 2. I promise you it won’t be the thing that costs time and money.
I won’t speculate further on something I noticed in passing but… very frequently the third play in the trifecta is to accuse your boogie man of something that you are doing as well. It weakens the opposing observation, true or not, by increasing difficulty in finding data (similar search terms… two different parties) and lizard brain “feels” like your arguement is weaker because its copying the opposition.
Either way - I’d hesitate to take an organization seriously if they fucked up their own.distribution platform that badly and didnt IMMEDIATELY fix it. Either they are inept or unaware… and unaware implies lack of traffic who might @ a dev.

PSA: If your router has a guest network feature, enable it, and put all of your IOT devices on it. Unlike the main network, guest networks are typically configured such that each device on the guest network can only access the internet, and not other devices on the guest network, nor the router, itself.
Or set up Home Assistant on a dedicated VLAN for all your IoT stuff. I know that’s a few extra steps that not every router will support, but it is a way to be more privacy focused (Home Assistant is entirely self-hosted) while still maintaining a lot of the IoT functionality.
Mine has guest and IOT networks, super nice because I can set up all the IOT stuff then hide the SSID
FTFY
How many death stars would that require?
I’ve set up a few solar systems (and, I agree, it’s a pretty ambiguous name). Generally speaking, they’re devices that include an MPPT charger (which regulates the power coming from the solar panels), battery charger, and inverter (which produces mains AC), often with a bridge rectifier that also allows the system to accept input from the grid, and a second inverter to supply power back to the grid. It a lot of kit in a compact package, so it’s unsurprising that they come with apps to allow them to be monitored and configured and, sometimes, support for automation in, say, Home Assistant.
And let me tell you: the majority of these things are fucking horrendous. I’ve lost count of the number of cheap Chinese units - with brands like LCERRZOPX and JRXYLNG, or provided whitebox so a fly-by-night European companies with a name like TotalCharge Voltacon Solutions can silkscreen their own logo on - which are guilty of every IoT sin imaginable: no local API or connectivity; plaintext communication to a data center in China; apps that force you to sign up and sends your credentials in clear text; apps that have not been updated since they were released in 2013 and crash constantly; no interface other than that fucking horrible app; and so on. This might seem like a minor thing, but if you’re depending on these things to run your entire house, you need access to that information, but I have to plead with people not to buy them because they’re €50 cheaper than the equivalent from a reputable brand. These devices are susceptible to anyone with a copy of Wireshark, let alone the manufacturers or Chinese government, and they’re just waiting to be exploited.
Incidentally, if anyone is looking at buying something like this, I can’t recommend Victron highly enough. Aside from their kit being high quality, you can access every feature using Bluetooth either from their own app, or a number of other apps that support their published protocols including, of course, Home Assistant.
Definitely. My dad also got a “solar system” and when he showed me how it works I was like “Are you aware that China can basically disable and/or destroy it with a click of a button?”. He’s been very paranoid and been trying to disable any remote controls since then.
The solution in my experience is to not bother with any kind of IP connection and try to find a serial port. If you can connect via serial odds are the protocol will have been reverse-engineered already. A cheap microcontroller can get it talking to Home Assistant and then you’ve got a well-maintained, self-hosted and open source way of controlling the system on your terms.
Feels like solar tech is like trying to buy real medicine in 1890. Mostly snake oil or alcohol.
Well, no. It all works and even the shittiest no-brand Chinese tat can reliably run a whole home with an EV or two. The systems I’ve been involved with have either paid for themselves within a couple of years, or are on track to. The problems here are nothing to do with solar and everything to do with poor quality IoT.
And that’s why you shouldn’t connect that stuff to the Internet in the first place…
Article created using AI. Ultimate facepalm!
That’s some Galactus-ass shit
I am too high for that headline right now.
Hope you’re not using solar to charge your vaporizer ;)
Why the hell do solar panels need wireless connectivity?
They are complex systems that need monitoring and management. Of course, there are well established ways to do this with zero-cost software and no need for any of the janky stuff that is on all this IOT stuff except a deliberate desire to monetize equipment after the sale via enshitification.
The inverters send status reports for tracking and auditing their production. unfortunately disconnecting some of these systems will cause them to go into standby mode after not being able to call home after two to three days.
So you can check out stuff on your phone?
Maybe?
Why would a toaster or a toilet? Or an ordinary vacuum for that matter.
Yep: https://www.ccc.de/system/uploads/382/original/hoymiles_dtu_vuln.pdf
My model is vulnerable, I have three of them. Hoymiles are real idiots, having made a model vulnerable to wardriving even if though not being online.
There is just no good reason for a solar inverter to even have the ability to be controlled remotely like that. Any wireless functionality should be limited to outputting what the inverter is doing, and air gapped from the firmware.
I completely agree. Nothing at home really needs to be controlled when not at home and if it is it should be through another network product you connect using wired
There’s only one solar system I know of that includes Europe and if they destory it, they’re just as dead as the rest of us.
Is this like an oil industry story? Like who would try this attack vector? And honestly how much damage could this actually do other than break peoples balcony solar panels?
Is this satirical?
Holy shit! The entire Orion Arm is in danger!
I’m drunk and need someone to clarify what a solar system is in this context
Specifically; this article is talking about the devices that convert DC power generated by solar panels into AC power that’s supplied to homes.
Seems they’re mostly talking about home installations, but this could effect larger commercial setups too.
Oh, that makes sense, I think
Ahh, so no special lasers heading off into space nuking other solar systems?
Stupid ass name.
please destroy facebook, Palantir or Elon Musk and Peter Thiel shit, not solar panels.
