I am generally in favor of security improvements, but I do not really see much of a benefit here. This attack vector requires both that the user enabled developer settings and that they have remote adb enabled. So, this does not seem to be a realistic attack vector for 99.9% of the users and most of the other 0.1% probably know what they are doing.

The other proposed change (to restrict access to certain interfaces or IP addresses) seems good, but why not allow developers to restrict access localhost?

It reeks of trying to block Shizuku, Canta, etc. using a way that only makes it look like a side-effect.

Not just that. A non-development Android build will also prompt the user when a connection is made to authorize the client's key.

This once again isn't about security of users, this is about security of the company's interests.

Google just got hit by yet another record antitrust fine by the EU [1]. But as long as they see these fines as cost of doing business, nothing will change. Especially if it always takes almost a decade to push this through the judicial system. Their net income last year alone was $130 Billion.

This. I'm a developer, I've published Android apps, & I've still managed to lose access to a device that had dev settings enabled purely because remote adb enablement is a (extremely fiddly) toggle that happened to be off on the device at the time the screen broke. Having these two enabled simultaneously is such a rare case in the wild as to be entirely negligible as a vector.

It seems to me a lot of Google lately is to block things they don't like using ways that only look like side effects.

The introduction of Manifest V3 API in Chrome for extensions, and disabling Manifest V2 for security reasons. It just so happened that ad blockers were made incompatible with the Manifest V3 API. It's a little blatant considering this came right around the time that YouTube began showing warning messages to users with ad blockers...

Requiring developers to verify their apps via Google Play Developer Console and blocking any unverified APK installations. This is done in such a way that it just so happens to squash F-Droid and most FOSS apps for most people, and blocks any serious competition to Google Play or any apps they don't like.

Of course, there's all this talk about preventing malware, but it is a fact that if you download any random ringtone or PDF app on Google Play it's going to come with probably 25 trackers and send your data to every jurisdiction in the world, and many apps even fail to declare any of this via Google Play data safety or privacy policy. Let's not forget that spyware is a form of malware. Take a look at the leaderboard :) https://reports.exodus-privacy.eu.org/en/reports/list/?filte...

In my opinion, this would probably be an indication that maybe Google controls too much technology and that they may need to be broken up to ensure fair competition. For Christ's sake they almost broke up Microsoft not that long ago for shipping a browser with their operating system, and now Google is blatantly controlling the operating system, the platform and app store, the ecosystem, the browser, the ad network, and abusing their power over it however they can.

Isn't this because of the kimwolf (and now 6+ other botnets) that are taking advantage of people running residential proxyware unknowingly on the device which permits outbound connections to 127.0.0.1 on tcp/5555 to auth in and exec wgets or drops a loader that grabs the ddos malware APKs and install it?
It seems to require the user to:

1. Enable Developer Mode by going to an obscure settings page and tapping the build number seven times

2. Enable USB ADB debugging in the Developer Options

3. Establish an actual USB ADB session

4. Enable TCP/IP ADB debugging in the Developer Options

5. Unknowingly download a malware app from the official Play Store

6. Blindly click "Yes" on the permission prompt.

In other words: this is all but impossible to impact regular users, and it requires a particularly careless developer to be hit by it. And it only works if the Play Store is useless at preventing malware in the first place - but I thought their excellent app scanning was the entire reasoning behind all-but-banning 3rd-party app stores and sideloading???

It is "for safety" in the same sense that governments banning all encryption is to "protect the children" or to "prevent terrorism": flawed justification invented to distract from the real reason they want it.

I think expert users on HN seriously downplay the ability and willingness of "regular users" to do very stupid things on their devices. If grandma wants that app that gives her a beautiful horse as a lock screen image, she will follow every one of those six steps that the malware HorseLockScreen app developer presents to her. She will tap a button that has a skull and crossbones icon, that says "tapping this will drain your bank account and kill your dog" if she thinks it will let her do whatever she's trying to do on her device. Have you guys never done IT tech support for your elderly parents' computers?

I'm not saying it's right to respond by simply locking everything down, but let's not downplay the blast radius of basically every attack that involves telling the user to do things.

Have you ever worked with someone who barely knows how to use a mobile phone? They will hand their phone over to someone they barely even know to do something they don't understand. They will follow instructions from a stranger over the phone, without understanding what the phone is warning them about.

I have worked with such a person. They did have someone walk them through a dubious process. Thankfully they realized what was going on before the process was complete, but who knows how much damage was done by the initial steps.

There are legitimate security reasons here. Whether there are reasons beyond that is an open question.

You haven't been able to connect to an android device on port 5555 for yeeears. Every time you enable adb/IP it generates a new random port, or you need to use the QR/PIN pairing thing. On top of needing to enable developer options, adb/IP, confirm the fingerprint.
Millions of Superboxes and various digital picture frames say different.

Hadn't thought about that additional attack vector those proxies are enabling. In addition to "internet access from residental connection" privileges, the attacker also gets access to loopback on the device that does the proxying...

But even then, shouldn't this show the same permission prompt for the user that anything else trying to connect to port 5555 would?

Yes, but users are told to allow it if they want to get free coins etc.
You can't fully protect people from the risk of taking bad advice from malicious strangers.

Not the least because most of our industry relies on it to make money. Marketing and advertising themselves are institutionalized forms of "do this thing that's actually harmful to you to get free coins / be safe / get laid".

> Not the least because most of our industry relies on it to make money.

I mean, this seems more like one of the root causes for a lot of bad things in the industry me...

Told by whom though? If it's through proxyware, then there are three parties who mostly don't know each other:

- the app embedding the proxyware SDK for money

- the proxy operators

- the attackers/botnets using the proxy to access ADB.

The botnet has no access to the app, so it can't show any messages.

The app can show messages, but probably has no connection to the botnet. (I hope)

The proxy operators could show a message by abusing the SDK even more, but that would mean they actively colluded with the botnet. Is that likely? Then they could just give the botnet direct access to the app, no need to do the whole proxy thing.

From memory, for the kimwolf exploit things, other user already had good points about the device already beeing compromised. But also, the authentification part of ADB was just completly disabled, which is why this worked. Basically it was so-compromised as-is that ADB was just sitting here open, as is you where to put SSH with no authentification at all.
There are so many people in my neighborhood here that are actively members of residential proxy networks that it makes me stabby. They don't seem to care.

That said, I wasn't under the impression kimwolf was that technically sophisticated. Some of the others are, though.

It's not because of security. It's to slowly close any avenues for side-loading stuff
It's not side loading. Word you are looking for is called "installing".
The bug literally describes how they're avoiding OS security restictions by going through the debug port.

This is a CVE by any definition and you'd be screaming your head off if any other OS would allow this kind of permission bypass (or even if another app did it).

But sure, Google evil.

There's a vulnerability in my bike - when I push my left handlebar hard forward when riding down a road, I can crash into a pillar.

I think a possibility of knowingly pushing the handlebar should be removed from me, just in case. After all I could do it.

And while we're at it I just realised my car has a similar vulnerability, but triggered by a slightly different mechanism, but the effect is exactly the same, I can crash into a pillar.

Edit: oops, I just discovered that if I have a banking app installed on my phone, then tap my screen in the specific places, enter several numbers, including the number I receive in text, suddenly I lose all the money.

That's staggering!

You, and may of the people in the thread here are at cross purposes, I think.

The CVE mentioned in the article is https://nvd.nist.gov/vuln/detail/CVE-2026-0073. That's a real CVE: logic error leading to auth bypass. Fix can be seen at https://android.googlesource.com/platform/packages/modules/a....

Separately, a number of people here are attempting to argue that the availability of On-Device ADB should be regarded as a "CVE" in and of itself. Google does not appear to share that view.

Or perhaps they wouldn't? CVEs aren't holy scripture, and "security" isn't the most important consideration in computing. This theatre has gone too far IMO.

Allowing strangers to run adb commands on your phone without your consent is about as bad as a compromise can get. Your keyboard can be replaced with a keylogger and all of your data can be stolen without your knowledge by simply connecting to the wrong wifi network.

Depends how you define a CVE. If owning and controlling your device is a CVE/bug then sure you need a tight box with anti tempering as well.
Can you provide a reasonable definition where an authentication bypass in ADB doesn't qualify as a vulnerability? Is there a use case for allowing anyone on your network to run adb commands without your approval?

There are 3 things which I feel like are being confused here:

1. There was a genuine authentication bypass vulnerability in ADB (bad)

2. Initial proposed change wants to add an option to limit the ADB server to certain IPs or network interfaces (good - it doesn't affect you)

3. Response to the original request, proposing that ADB shouldn't be allowed to listen on loopback interfaces (bad/nefarious - it breaks functionality)

"An app can bypass OS security system with certain setting enabled" absolutely fits into CVEs. There's no "depends: on it.

I love how quickly you all forget about security and privacy when it gives a chance to angrily rant.

The original issue is proposing letting the user assign the debug service to a specific interface, one of which would presumably be loopback. This article is about the proposal from a developer that it should only ever be assigned to wlan0, which would break a lot of apps.

Letting applications bypass permissions with this feature is the exact usecase they don't want to lose. If anything, I don't see them being against the original proposal possibly restricting non-loopback access, which would enhance security.

It would break exactly 0 apps because none of the apps should be using this API to access your private data and phone call audio.

Because you know, the actual solution would be to have more granularity in authentication process than "allow whole device to attach to ADB", but that would be like, difficult... so they're not going to so that.

Right now any app on my PC connected to ADB could manipulate my phone then, and that's somehow not a CVE?

Is it a CVE that an app running on my PC could actually be running under GDB? It's the entire purpose of these tools.
In this case, the OS security restrictions should be questioned in the first place as excessive if a "backdoor" is necessary for normal function.
I am not sure I follow. Are you referring to the original CVE (?), I fully agree that it should be fixed, and it is not what my comment was about.

If you are talking about allowing listening on localhost - remote ADB requires enabling in the developer settings. It is a developer feature, similar to ADB over USB. If I'm charitable, it is possible that they are seeing too many people that are using Shizuku without understanding the security implications. But Shizuku has a lot of useful applications and they use ADB because the Android APIs and permission system are lacking and do not make these applications possible.

New CVE found in Bank of America app that may cause user to transfer money to hackers if they press certain combination of keys.

"...avoiding OS security restictions by going through the debug port..." the user delibretry opened and paired to app with clear visual confirmation in order to use it.
Even if you have to deliberately enable a setting and enter a pairing code?

It's like saying that the fact the user knows their own password is a vulnerability because they might enter it to log into their account.

no, its a cve if the app can just do it automatically, it is NOT a cve that user goes through 5 steps that they very explicitly do, including unlocking hidden menus to open up developer options, and then allow it.

seriously, get real, please explain how your train of thought works here
