Hello,
Thanks for taking some time to read this. Let me start off by mentioning that this all originated on my PC I believe and an unauthorized user obtained access to my network and therefore all my devices.
My OnePlus 7 Pro was what seriously concerned me as not only was it infected, the attacker actually pushed a firmware update to my phone and it randomly reset as I was using it into a completely different/custom rom that he of course had complete control over.
I upgraded to a OnePlus 8T and after walking out of the T-Mobile store I found out my new phone was already infected.... How? Well, the escalated priviliges this attacker had allowed him to auto connect to my OnePlus device using the OnePlus SmartSwitch app. Yeah, I thought it was crazy too.
So I've tried to hard reset my devices, which actually turned out to be a bad idea as this infection actually hijacked the the process by (I'm not super familiar with reading all the log data) but it was clear that multiple main processes were killed and it took control and a warning popped up saying (WARNING! This is a Debug Kernel and is not fit for a standard ROM. If you did not authorize this then your privacy may be at risk as this could potentially allow an unauthorized user complete control of your device" it was something along these lines, may not be the exsct wording but you get my point. (This was on my Samsung Galaxy Tab S7+)
More or less the same thing with my OnePlus 8T and it has complete control over all of my apps. The permissions my apps have are literally insane. I've attached screenshiots.
How can I mitigate this? What should I do? It has infected my 2017 MacBook Air, PC, OnePlus 8T, Samsung Galaxy Tab S7+, Asus ROG Rapture GT-AX11000 Router, Netgear Nighthawk Router and possibly more. This thing is crazy advanced to the point I didn't even know malware like this existed.
ALSO: I found out that Busy Box is installed on my devices without my authorization BUT my device isn't rooted.

When I tried to mess around with my Developer's options, it showed that I am not the administrator. It doesn't allow me to turn on "Restrict my SMS and call log access" under Apps, and a bug report I opened and had looked at gave me these additional specifications I had never seen before:

Besides this, all of my applications have been compromised; they all have odd versions, permissions I cannot control (such the system app, Tips, being able download files without notifying me), can change system settings, install unknown apps, have "Open source licenses," and so on. Some of the capabilities that my app, Messages, has is the ability to modify my call logs, send out messages without my knowledge (then delete them), use my microphone to record at any given time, and connect or disconnect from Wi-Fi. It's quite difficult for me to find authentic information online, because my Google Chrome app constantly gives me false redirections to fake/modified links that appear legitimate.
Everything on my phone will tell me that the apps, the websites, and the operating system are safe and authentic, but they're all infected. I have been under the false impression that nothing was wrong with my device for months now, because judging from my Wi-Fi usage history, it had spiked up between June-July.
I'll also go ahead and attach a sh*tload of screenshots on what the malicious, system applications look like.

Thank you, I was planning on doing so, anyway. I'm just learning as much as I can before I reinstall the stock firmware, such as if there's a method I could use that wouldn't trip Knox because I like using some of the Samsung applications.
I have 2 other phones that have been compromised, as well, and the hacker knows, essentially, all my passwords now to all of my accounts, and has access to my SIM card/number. It's frustrating that when an application requests a verification code, I get messages like these:
<#> Account: [redacted] is your Samsung account verification code.

I have the same issue now going on for 2 years.
I have changed everything from emails devices wifi and cel companies. I've been super careful to not access any infected data from previous devices. On my new note 20 5g ultra out of box disabled blue tooth and dis not connect to any wifi so far. I di not transfer data from any device..
I've lost so much time and money trying to get rid of this. I've lost all 99 of all my Pic videos for over the past decade emails and social media accounts.
Knox has been activated I tried to access the account but I've been unsuccessful.
Has flashing it work for anyone else. I have on previous devices galaxy 8plus just to reverse back to the compromised state.

To be honest, I eventually gave up on it because whoever it is that wants access to my devices clearly has the resources to do so.
On top of that, no one would believe me when I tried to explain to them how serious it is and all the information I've gathered to prove my point.
Unfortunately, I'm not fluent enough in coding or low level system management to professionally explain my concern for anyone to listen to.
I came to the realization that in the bigger picture, I'm a nobody in the cybersecurity field and what that means is no one will take me, and most likely you, seriously nor do others want to spend their time assisting us for anything short of a fortune.
If you are experiencing something similar to what I've posted here then chances are high you are being targeted specifically and without the relevant cybersecurity knowledge to protect yourself, you will never get away from it.
Hate to be negative here but I can assure you that I spent countless days, weeks, months trying to figure it out by researching, contacting cybersecurity specialists, forums etc. all to no avail.
I genuinely wish you luck and if you happen to find some information you could share with me, I'd appreciate it.
Outside spending a small fortune to hire an expert to come to my house and dig deep into my network, I don't see a way to resolve it, personally.
Good luck

I really hope you were able to get this fixed. I haven't been able to since my entire network has been infected. It's a really long story but the bottom line is that I've never seen malware with these capabilities. They are incredible and not one you would ever want to be infected with.

I'm very sorry to hear that, I can't imagine what it's like to have to deal with this for such a long time. I slowly started losing my sanity when my devices were infected, especially my primary device (the Samsung Galaxy S9+), and had started becoming irrational at times due to the paranoia and lack of understanding about what had been going on the entire time.
I have yet to flash any of my devices, so I don't know just how well it'll work out doing so. What Android version is your Samsung Galaxy S8+, though? Because devices running on Android 9 (Pie) and up are pretty unique in the sense that the security rids the device of malware & spyware once a factory reset takes place, so if you have a newer operating system like you do on your Samsung Galaxy Note 20 Ultra 5G, then you may be able to fix that issue. Although, it would only clear up issues you have on your firmware/software & not be able to help issues you'd occur with a compromised hardware & network connection.
When I factory reset my Samsung Galaxy S9+ (which runs on Android 10), the oddity disappeared! I wish I had done it sooner or routinely, at least, because it would've saved me from so much stress & anxiety.
Although, as @JesseJamez55 mentioned, you may be directly targeted, and that makes a huge difference in the matter. I, for one, am not specifically in the center of attention — my best friend is, and I suppose I somehow got involved in this awfulness just for knowing about so many of the concerning experiences he's had in the last several years.

I was planning on doing the same thing when I had gotten tired of it; I was just going to accept that my life will always be this way and there's nothing I can do to try to stop it from happening because I wasn't educated enough about the problems I was facing, and couldn't find any real information due to the DSN spoofing.
It's best to not share this with too many people — we'll end up looking like nutjobs, which we probably are a little of, due to apophenia & the heightened stress/anxiety (causing paranoia), haha. But in all seriousness, the people of people won't understand or believe is — especially when we're more suspectable to being discredited.
I think that's what the hackers/stalkers do — pick out & mess with those that have disadvantages (such as if one uses illegal substances known to distort our thinking or if one is diagnosed with a serious mental illness) because we're easily discredited.
How long has this been happening to you, if you don't mind me asking?

I was extremely relieved when I found out there are others that believed me too & who were suffering from the same issues & malware.
I was able to get it fixed, thankfully, but I've also changed my way of thinking about this whole thing. I've started taking my medications, too (or I'm starting to again). And I agree, it's definitely a considerably severe form of electronic harassment. But I suppose it's inevitable, and there's no point in stressing out so much over it anymore — for me, at least.

Your completely right. I thank you for your feedback and I greatly appreciate it. I usually get laughed at or from IT support at cox or other companies that will explain how to what is happening to my digital life is none existent and has not been developed yet and send me on my way after a virus scan resulting in 0 threats.
Your also think your right been someone targeting me. At this point I need to get my foil hat.. I really don't share that thought because even my bf has advised me to get a mental health evaluation... I understand after hearing me try to figure it out for mths 24/7..
This is the reason why I believe that it is a possibility. When all this came about I lived in North Las Vegas it's pretty bad unfortunately I didn't know when I bought and moved in from California. I felt safe it's a gated community!
I'm just gonna lay it out and I know what I sound like and I did end up going to get checked out clean menta aside from some anxiety from all of this.
After moving in a mth later I had some tampering with my truck but wasn't sure maybe by accident I did it .. I was always on the run.. but a few wks later I heard the back door open and I asked who was there and I caught someone's backside running out. I figured some stupid curious teen .. so concerned me living alone employed running a company and also a side business flipping cars and a truck a sports car and a classic that I was rebuilding.. maybe was drawing attention of the wrong kind. I got me a dog! Problem fixed um no still night noises outside and once on the roof that my BF was there that night and we would call the Police dept.. over and over again. So time to get cameras. Started with the ring system I had cameras in every direction including a couple inside. It was amazing! For a day that night someone tripped by breaker lost power again we ran out it was the BF of the person that managed the community... another police report for the pile. To make it short unless I was looking at it live what ever that was recorded I would get to see it original video maybe once and when I would try to show someone video would be gone or edited (at the time I did not know that video could be edited or set privacy guards filters from amazon etc) also I would started to see at night someone with lazer pointers. Later I was told it would disable the camera. True or not after looking like a mad woman with claiming to have proof to call the police.. and I no longer had the evidence no matter where I would back It up to.. I was mad all that money on the ring for this BS.. so I got Canary then I got Alfred and a long list of cameras apps and all the same. Luckily I was giving some credit when on a motion in an inside my home you could see a hand reaching to move the camera a I was able to show my BF and a friend but by the time pd showed up the video had been edited and the beginning with the dogs barking and the hand over my bed reaching for the camera was missing.. yes someone was in my bedroom while I was asleep and my BF was in bed asleep with me. The other hard evidence was not digital.. I was in the bathroom and heard noise coming from under my home.. I screamed out for help to the people that had come over for a get together. They saw the guy run from under the house and they chased him about a block and jumped into a waiting minivan. The rest of evidence I had in video that I once could see actual break ins in process and video with excellent quality would with in a min turn to a smear of colors exta zoomed imaged glared lights .. that nobody believed that I saw the person committing the crime. I had kept the videos and images of my smeared proof with hopes that one day I could get help and reverse the editing that destroyed my proof. I don't have many left..
After living in fear with most of my belongings and valuable stolen a walked away from my purchased home to rent in a safer neighborhood. Un the process I lost my job my side business..the classic dismantle my truck crashed into while parked at night hit and run ofcourse and turbo taken out of sports car .. and almost losing my mental.. having to deal with "hacking" constantly having to change passwords removing my device form child restrictions or fighting with my own virus protection software that would be program to restrict me accessing help and getting error codes when accessing government agencies google cox and tmobile.. it was the worst I believe. I'm glad I'm safe but still with this issue issue.. I've been trying to learn on my own and I Google everything.. I mean every word I come across and YouTube if I need further clarification and I started taking some classes to understand and remove and prevent what is happening to me one day.
Sorry about the novel.. lol
I'm going to attach a sample of my smeared images and some images of the modification that I have currently maybe someone understand all of this
Where I'm at .. I bought this phone and did not connect to wifi disabled blue tooth and disabled automatic downloads and I had not even turned on my data .. so I looked into OTA .. over the air programing and issues with samsung the data breaches etc.. I talk to samsung they said the modifications was not via OTA .. the IT rep could have been right ?? Not sure yet .. how else could possibly else be .. (about 2 years ago I found in my google shared doc that I was sharing to other my experiments results with radio data communication.. and was very common for me to see the verbiage spectrum radio, RTU, Scada, unlicensed radio, IoT, Ericson, transmitting data over radio as a wifi alternative. Alot of the apps I had then had something to do with that technology and companies) My ignorance at the time told me it had something to do with the huge radio antena that came with the home.
So I revisited that idea as a possible entrance point of infection??
I found libav64 with over 1060 system files saved on my device
Also in the framework files I found several of Verizon files.. I have t mobile never had Verizon. Because I have a Verizon build enforcing t mobile .. tmobile support accused me of inserting a Verizon chip .. I explained that I don't have one and never did .. she asked me to return it manufactur and exchange for new one.
I'm having an issue with upload speed for the images so I will repost with just the images

I'm very sorry to hear that, I can't imagine what it's like to have to deal with this for such a long time. I slowly started losing my sanity when my devices were infected, especially my primary device (the Samsung Galaxy S9+), and had started becoming irrational at times due to the paranoia and lack of understanding about what had been going on the entire time.
I have yet to flash any of my devices, so I don't know just how well it'll work out doing so. What Android version is your Samsung Galaxy S8+, though? Because devices running on Android 9 (Pie) and up are pretty unique in the sense that the security rids the device of malware & spyware once a factory reset takes place, so if you have a newer operating system like you do on your Samsung Galaxy Note 20 Ultra 5G, then you may be able to fix that issue. Although, it would only clear up issues you have on your firmware/software & not be able to help issues you'd occur with a compromised hardware & network connection.
When I factory reset my Samsung Galaxy S9+ (which runs on Android 10), the oddity disappeared! I wish I had done it sooner or routinely, at least, because it would've saved me from so much stress & anxiety.
Although, as @JesseJamez55 mentioned, you may be directly targeted, and that makes a huge difference in the matter. I, for one, am not specifically in the center of attention — my best friend is, and I suppose I somehow got involved in this awfulness just for knowing about so many of the concerning experiences he's had in the last several years.

My situation isn't on Android only, it's my entire network which includes the following;
PC's
Android Phones
Android Tablets (No longer own)
Macbook Pro (No longer own)
MacBook Air (No longer own)
Chromebook (After allowing Linux via Developer Settings)
Router
Samsung Smart TV (No longer own)
Sony AV Receiver
My CCTV DVR System (No longer own)
Any other device that either connects to my network or can be accessed via the Nearby Devices pervasive permission within Android (This is my best guess for how devices are being infected when I haven't in any way accessed my network)
After all my research and some helpful clues/texts/emails sent to me, i found out that I am being specifically targeted by my upstairs neighbor that strongly dislikes me and finds me extremely amusing.
I won't go into further details but this is why I gave up. They are exponentially more fluent in cybersecurity than I could ever hope to be and since they have local access to my devices, I could never hope to win. I need to move which I will be doing very soon.
This is why I say if you are going through anything close to what I am then it's almost certainly a targeted attack. I'm sure there are other possibilities but this is what my experience is.
Do you ever use the Tor network? Depending on where you decided to browse or what you may have downloaded, you can get some especially nasty malware from there, too. Even just browsing some sites can deliver drive-by malware or not having your browser/firewall set up correctly is enough to lose your anonymity. Something to think about since it could be a government agency keeping tabs on you for a reason only you would know. Just a thought.I'll leave you with one final thought; would you honestly consider yourself a very interesting person? Do you have hobbies others would be interested in learning more about it they had the relevant skills to do so?After thinking about it, I do. I have my hobbies that I would find different or weird if I were someone else. So that mixed with some neighbors that have networking skills, are always home and way to damn nosy is how I got where I'm at.That's my real situation so just something to consider.
I am so glad I came across this thread. Honestly. Had the exact same issue Dec last year. Although I suspect they were in the network for a couple of years before I realised. Tried to solve it for 6 weeks. Gave up, threw all network devices out and started over. All good. For three months. Even with the most strictest routines in watching what I was clicking online, not downloading anything, updates ran regularly, new vpn and more costly antivirus and equipment. It returned.
I honestly don't think its a personal attack, but it's insane how it spreads. I've worked constantly on it since June. Contacted so many people. I can't afford to throw this new stuff out, don't have money to replace it all again. My doc sent me to see a psychiatrist. Said I'm delusional. I told them I was feeling stressed and exhausted just trying to boot whoever this was out of my network and life. Psychiatrist says I'm sane, just needing to relax and have someone actually listen to me.
I have 2 pcs, laptop, 3 mobile phones, xboxes and TV being controlled by whatever this is. Root trust certs are all wrong. Traffic being directed to http although looks legit as if its https. All have been flashed with wrong ota updates. I am considering flashing my phone but don't think it will help as will be doing it with infected pc... seems pointless.
I am starting to realise I have to live with it and just get on with stuff. I've been seriously slacking in work and been so focused on this malware/spyware/rootkit whatever it is.
Honestly it's a massive relief to know I am not alone.
I am having the same issue. What I have learned so far:
> The malware is a RAT

I will attach screenshots a bit later.

One more thing that is particularly disturbing: It appears to be connected to my vehicle BT and Uconnect interface. There is more, but I will inckude that later as well.
This is exactly what I am facing.
It seems like it has been a couple of years.
Yes the LED of the camera is off too.
Did you manage to solve it ?
Anyone with a solution?
To be honest I'm not into the cybersecurity field but it sounds like the ultimate type of malware - one that hacks everything conveniently. I hate to say it, but you might have to replace literally everything. You could try to at least backup some stuff that's important but you're going to have to look at the local technician to see what you need. I could provide some help for those who need it in this forum.

Your completely right. I thank you for your feedback and I greatly appreciate it. I usually get laughed at or from IT support at cox or other companies that will explain how to what is happening to my digital life is none existent and has not been developed yet and send me on my way after a virus scan resulting in 0 threats.
Your also think your right been someone targeting me. At this point I need to get my foil hat.. I really don't share that thought because even my bf has advised me to get a mental health evaluation... I understand after hearing me try to figure it out for mths 24/7..
This is the reason why I believe that it is a possibility. When all this came about I lived in North Las Vegas it's pretty bad unfortunately I didn't know when I bought and moved in from California. I felt safe it's a gated community!
I'm just gonna lay it out and I know what I sound like and I did end up going to get checked out clean menta aside from some anxiety from all of this.
After moving in a mth later I had some tampering with my truck but wasn't sure maybe by accident I did it .. I was always on the run.. but a few wks later I heard the back door open and I asked who was there and I caught someone's backside running out. I figured some stupid curious teen .. so concerned me living alone employed running a company and also a side business flipping cars and a truck a sports car and a classic that I was rebuilding.. maybe was drawing attention of the wrong kind. I got me a dog! Problem fixed um no still night noises outside and once on the roof that my BF was there that night and we would call the Police dept.. over and over again. So time to get cameras. Started with the ring system I had cameras in every direction including a couple inside. It was amazing! For a day that night someone tripped by breaker lost power again we ran out it was the BF of the person that managed the community... another police report for the pile. To make it short unless I was looking at it live what ever that was recorded I would get to see it original video maybe once and when I would try to show someone video would be gone or edited (at the time I did not know that video could be edited or set privacy guards filters from amazon etc) also I would started to see at night someone with lazer pointers. Later I was told it would disable the camera. True or not after looking like a mad woman with claiming to have proof to call the police.. and I no longer had the evidence no matter where I would back It up to.. I was mad all that money on the ring for this BS.. so I got Canary then I got Alfred and a long list of cameras apps and all the same. Luckily I was giving some credit when on a motion in an inside my home you could see a hand reaching to move the camera a I was able to show my BF and a friend but by the time pd showed up the video had been edited and the beginning with the dogs barking and the hand over my bed reaching for the camera was missing.. yes someone was in my bedroom while I was asleep and my BF was in bed asleep with me. The other hard evidence was not digital.. I was in the bathroom and heard noise coming from under my home.. I screamed out for help to the people that had come over for a get together. They saw the guy run from under the house and they chased him about a block and jumped into a waiting minivan. The rest of evidence I had in video that I once could see actual break ins in process and video with excellent quality would with in a min turn to a smear of colors exta zoomed imaged glared lights .. that nobody believed that I saw the person committing the crime. I had kept the videos and images of my smeared proof with hopes that one day I could get help and reverse the editing that destroyed my proof. I don't have many left..
After living in fear with most of my belongings and valuable stolen a walked away from my purchased home to rent in a safer neighborhood. Un the process I lost my job my side business..the classic dismantle my truck crashed into while parked at night hit and run ofcourse and turbo taken out of sports car .. and almost losing my mental.. having to deal with "hacking" constantly having to change passwords removing my device form child restrictions or fighting with my own virus protection software that would be program to restrict me accessing help and getting error codes when accessing government agencies google cox and tmobile.. it was the worst I believe.

You need to right now remove the malware, as that's the problem. The symptoms of this malware seems to be that people randomly attack you because they know your location and are listening to you 24x7. You remove that malware first and then fix the home security later. Good luck
This seems a bit over-exaggerated, the "dangerous" processes you're talking about actually look like normal services on a samsung device lol, it's not uncommon for some frameworks and stuff to have a lot of privileges, the message you're saying you see on boot could maybe be the:
Code:
The phone is not running Samsung's official software. You may have problems with features or security. and you won't be able to install software updates.
This is typical for a bootloader unlocked/modified device, feel free to send photos of the messages you're describing, and it can help point into the correct direction.
The "traced" app you're using seems very misinforming though. The Call app having permissions to call and read storage/contacts is normal.
If you're really that paranoid about random services (which look fairly normal) - feel free to format everything, debloat down to the core OS, wrap your walls in tin-foil, throw out your phone and hide under your bed lol (sarcasm)

could that infection be called "blink" by any chance? it's a serious piece of software that makes its way onto every windows and android device without user discretion. that sounds a lot like what's happening, and blink has the ability to utilize any active internet connections when activated.

Hey,
Germany is implementing EU-Alert (ETSI TS 102 900 [1]) at the moment and referring to the local News, it is a huge mess [2].
But let's start at the beginning.
CellBroadcast is a core component of each mobile network generation (2G,3G,4G,5G,...) and part of the 3GPP spec. CellBroadcast basically allows the network to send a simple SMS to all mobile phones connected to a specific base station. Thes SMS-CB are sent with a Message Identifier (aka Channel, aka Topic) which gives them a special purpose by convention. e.g. ID / Channel 50 is often used for area related information [3], while channel 207 might broadcast local weather information. Since not all Channels are standardized, there is also the option to broadcast an Index that lists all channels with a description. And since users probably don't want any message broadcasted, users have to subscribe to these channels.
Since decades now, CellBroadcast is also used for public Emergency Warnings. This means that, by definition of a country, a specific channel is used to broadcast Emergency Warnings. Long time ago, in many countries it looks like Channel 919 was used for this purpose. For this to work properly, mobile phones were instructed to subscribe to channel 919 by default and also use a special ringtone (even if muted) to alert such a message.
Later - over 12 years ago - additional channels from 4370-4399 were standardized in ETSI TS 123 041 [4] for public warning systems like CMAS, EU-Alert, KPAS. All using the same channels which is beneficial for global roaming.
Android of course supports these public warning systems specified in ETSI TS 123 041 [4] since at least Android 4.2.2 [5]. And nations that use these systems already, like CMAS in the US, report very high and reliable coverage.
However, referring to German news [2] and government, not many phones that are currently on the market will actually support EU-Alert in Germany, despite already supporting EU-Alert in Netherlands or CMAS in the US.
How is this possible when exactly the same SMS-CB is broadcasted, just in a different country?
Golem [2] says that Samsung and Google already confirmed that EU-Alert is currently not supported in Germany, but updates will be rolled out to recent devices.
This strongly suggests to me that OEMs like Samsung and Google actually added country specific filters/configurations for these public warning systems to their phones without deploying a reasonable fallback. Public warning systems based on ETSI TS 123 041 [4] thus may only work in countries that were known to use these systems when the phone was released.
Isn't this an obvious issue?
Google said, starting with Android 11+ it will be possible to update the CellBroadcastReceiver App via Google Play. So devices with Android 11+ will likely receive an update to support EU-Alert in Germany. For Android 10 and older, OEMs will have to supply updates.
What also confuses me is the fact that all Android Phones I own (Nexus 4 with Android 5, Nexus 5X with Android 8, Pixel 3a with Android 12) here in Germany do actually offer the setting for Emergency Warnings and they are already enabled by default. So I assume they would work? Did Google actually deploy a sane default configuration here already?
But if they did - why isn't it working on ALL Android 11+ Phones already? I'm pretty sure my Pixel 3a uses Googles CellBroadcastReceiver App which is provided through the Play Store. So all Android 11+ phones should already use the exact same App?! Or am I wrong here? So what is this update Google actually needs to provide?
And does this also mean that with Android 11+ OEMs are not allowed / cannot implement their own Emergency Warning CellBroadcastReceiver?
This topic is really confusing to me
Shouldn't it be really simple?
All phones, regardless of the OEM, should have a proper SMS-CB Application which allows you to subscribe to custom channels, view the index, and manage your SMS-CB Messages.
Phones should also be aware of special channels to apply special ringtones etc if needed, but they should have a sane fallbacks!
A phone that knows about NL-Alert and CMAS may call messages on Channel 4370 received in the Netherlands "NL-Alert". But when it receives the same message in Germany, it shouldn't just drop it! It should display it as warning and call it whatever it wants. And if it doesn't know about CMAS / EU-Alert, it should just receive it as regular SMS-CB.
Can't be that hard?
Interestingly enough, Samsung phones allow you to subscribe to custom channels. Google phones do not :/
Should there be a better / more enforced standard, so that a country that wants to implement CMAS/EU-Alert in the future doesn't have to rely on OEMs help?
And finally some technical Questions:
I found zero Apps for Android that would allow me to subscribe to custom CellBroadcast Channels on my Google Android phones. Is this even possible?
Also, is it possible to test these CellBroadcasts somehow? Is it possible to write an App that can inject SMS-CB into the system?
Sorry for the long post, but I think this an important Topic.
Let me know what you think
Do you have experience with these Emergency Warnings already?

Hey! I was just researching something about this. Thanks for your detailed post.
I am from Chile and, in my case, my operator had subscriptions to two channels: 919 and 920.
In order to see the Cell Broadcast menu in the Messages app, I had to override a CSC setting (I use a Samsung device), particularly "CarrierFeature_Message_DisableMenuCBMessage") because it seems some Chilean operators ordered Samsung to hide it.
Even then, the Google Cell Broadcast app would not let me modify settings other than test alerts.
In my country these emergency alerts are quite unreliable and are often sent by mistake or to the wrong place (i.e. sending a tsunami alert to an area more than 100 km away from the coast).

Can you explain how you disabled this CSC setting and on what samsung phone/os?
You can see Googles/Androids latest default configuration for Chile (MCC 730) here:
https://cs.android.com/android/plat...apps/CellBroadcastReceiver/res/values-mcc730/
The config.xml really has some restrictive features enabled :/
Thanks for your reply!
Please note that all the following information assumes you have rooted your device. It's impossible to override this configuration otherwise.
My device is a Galaxy Note20 Ultra (Exynos version, SM‑N985F) running Android 12, One UI 4.1.
As you might know, Samsung devices include several packages named “CSC”, which define settings according to a sales code matching with a region. For example, a device sold in Chile without a carrier uses the sales code CHO, while one sold by operator Movistar uses the sales code CHT.
In the Galaxy Note20 Ultra, the CSC packages are stored in /optics/config/carriers/single (older Samsung devices might use /omc/).
Once you find the sales code matching with your current configuration, you can grab two files: cscfeature.xml and customer_carrier_feature.json. Taking CHO again as an example, the files would be /optics/config/carriers/single/CHO/conf/system/cscfeature.xml and/optics/config/carriers/single/CHO/conf/system/customer_carrier_feature.json.
These files are encoded, but OmcTextDecoder can take care of that.
In the case of CHO, customer_carrier_feature.json has the value "CarrierFeature_Message_DisableMenuCBMessage":"TRUE", which hides the cell broadcast menu in the stock Messages application. Just replace “TRUE” with “FALSE”, save the file and push it to its location. The next time you reboot your system, it will be applied.
Regarding the link you sent, I think we could get around that configuration by decompiling the GoogleCellBroadcastApp.apk through Apktool, modifying the restrictive values, and then pushing the APK to the device, replacing the original version.
Thank you!
Let me know if you managed to patch your original CellBroadcastReceiver.apk!
I actually tried using Runtime Resource Overlays (RROs) which is described on the official docu about CellBroadcast in Android.
You can find the result here: https://github.com/xsrf/android-de-alert
However, I didn't quite get these RROs. It looked like in Oreo you can use RROs to overlay any resource of any app without any permissions or matching signatures, which is quite a surprise to me?!
On my phones with more recent OS, I get signature mismatch errors and also it looks like apps now have to define what resources can be overlayed ...
