As somebody who occasionally had to develop for android: the churn of improvements to app security was a huge pita. And as a user I know many of the abandoned apps that I liked that lost compatibility was for that reason.
So the fact that in spite of this pain, Android security still allows apps to do horrible crap like that is infuriating.
The app doesn’t contain malware when it’s uploaded to the play store. It forced an update after it’s installed that contains the malware.
That’s not what I mean. I’m not thinking about Play Store security, but Android OS security. Like, your app physically has to ask for permission (or even require the user manually change settings) to do most unsafe things.
Physically? So the dev has to come ask you in person?
By mail, even
It does, you have a full screen scary warning when an app asks for these accessibility permissions. Clearly many people just give it to a random QR code reader app for some reason.
So I could write an app that is okay on the Google store, then change it to steal people’s information? Hmmm 🤔 that gives me an idea…hahh! Too many projects at the moment.
According to the report, the app just displays a fake login page. I don’t see a good way to prevent this.
If you read the original report, it says that it basically just displays a fake banking login page. It also says that it requested accessibility service permissions, which makes me think maybe it brought up the fake login pages “in the right moment” (as in as users opened their banking apps) to make it more convincing, even though the article doesn’t specify that.
Either way, IMO the problem here is clearly with the Play Store allowing this app in, and not with Android’s security itself. These apps are misusing the accessibility service system, which is obviously necessary for a ton of important use cases (and of course also requires the user to grant very explicit permission). The fact that the accessibility services are a thing doesn’t delegitimize Android’s security improvements over the years.
If a user can open their baking app, and this app can sense that and open instead, then that is 100% an Android issue. That behaviour shouldn’t be possible.
“Accessibility service permissions” is a higher level of permissions than most apps get and Android will be all like “bro, are you sure you want to grant this app that kind of access and control? You really sure?” I’ve got a few apps on my phone with that level of permissions including one written by Google. They’d simply be unable to do their job without that level of access, jobs which have been straight-up good for my physical health. Ultimately there’s a balance between security and letting the user do what they want.
iOS user: That’s a shame.
But seriously, this sucks and is why Google needs more rigorous vetting of apps that go into the store. Sure, you sideload, that’s your problem. But if on the Play Store, the general Android user would think there’s some good level of governance.
Of course there’s a measure of caveat emptor here. So hopefully it’ll teach people to be wary of what information they freely give out.
AI probably “wrote” that
no list of apps anywhere
Jup. It just says that “the malware was disguised as PDF and QR code readers”.
Not helpful, Mashable. Not helpful at all.
In fairness to Mashable, this isn’t their fault. The people that made the report didn’t make the list public.
Then why is this the subtitle:
The apps identified have since been removed from Google Play, but make sure you didn’t install one.
Because tech journalism is trash on the best days, and these android malapps articles only ever amount to blogspam to make you nervous. I don’t think I’ve seen more than a handful of these articles that actually warns you about the actual apps instead of just talking about the problem without relevant specifics.
I got many apps installed. I don’t keep in my memory what I have. How do I check that I don’t have any from those compromised?
Go to Settings and search for Google Play Protect. Tap Scan, and if it results in No harmful apps found, you’re safe.
Aren’t apps on android hermetically sealed from other apps and malware. How could this be achieved ?
Yes, the app doesn’t steal any information from other apps. The report says the malware just displays a fake bank login page, in the hope the user gives it their details willingly.
Since the other reply was unhelpful: apps are supposed to have limited privileges and isolation from each other, yes… But the whole point of malware like this is that they figure out ways to break those restrictions and get escalated privileged.
You can get more technical detail from reading the report, in this case it looks like the app does not contain malware, but instead requests an update after install that contains the bad code and then breaks the app limitations and scans for the target banking applications and copies the security certificates.
As a developer this question is hilarious to me
please enlighten the rest of us
Why? They’re absolutely right. The article doesn’t say anything about a root exploit or phishing either so were left wondering…
He’s being condescending because he believes as a developer nothing is actually fully secure. If I spend 100 hours building and securing something, that’s not going to stack up very favorably vs the 1,000’s or even 1,000,000’s of hours attackers and communities can spend trying to break my security layers.
Basically, he’s a dick in how he answered the question, but the truth every software engineer learns, is that there is no fully secure system. There’s always an angle/attack vector you didn’t think of and secure.
Of course there are (or there can be) fully secure systems. The problems come when you assume something is.
They actual report does say it just displays a fake login page. It’s just phishing.
Explain yourself
As a curious Android user this comment is useless to me
As an Android developer that comment makes me sad. Then I remind myself that Lemmy is full of people who migrated from Reddit.
Dude, do you not want people on this platform? Reddit migrants come with baggage yes but I’d rather that than the husk that was Lemmy before.
I’m not gonna scream back at you,… I’m just going to walk back… very… very… slowly…errrrrrrr
We each have our specialties, and it would be unreasonable to ask that everyone share yours.
For a real answer here’s the Zscaler blog write up: https://www.zscaler.com/blogs/security-research/technical-analysis-anatsa-campaigns-android-banking-malware-active-google
It looks like they are doing it after app install with a malicious patch. This patch asks for SMS and accessibility access to gain privileges necessary to get into the banking apps. I haven’t thoroughly read it but just looking at the attack chain that’s what I gleaned.
Ugh, TIL zscaler actually does more than just send my PII to the USA without my consent.
and one day you’ll say why, right?
And this right here is why you use open source apps.
This only would work if you check every line of source code, even the dependencies and build chain, and then build it yourself. See xz utils backdoor or heartbleed, etc.
check every line … yourself.

A very classic lie, disinformation, used to spread anti-libre software. Anti-libre software bans us, not only me but everyone else, from removing malicious source code.
Very disingenuous of you to fight a strawman and proclaim victory by claiming that I said things which I never did. But if that’s what floats your boat. But for everyone else, try to find any mention of anti-libre software in the original claim.
‘Open source’ is created to subvert libre software.
What are you talking about? You are digging yourself in a trench against me for some reason and you dig deeper every time. I have no idea what your agenda is, but I am stopping participation in it.
I don’t know about you but I have always been a free software advocate, see
- https://jeena.net/why-i-switchedfrom-osx-to-linux
- https://jeena.net/pods/14
- https://github.com/jeena/
But anyway, I’m not interested in whatever this discussion derailed into.
Then, you would know anti-libre software bans, not you, us separately and together from proving its claims and removing malicious source code.
Exactly. Neckbeards love to pretend open source magically has no security vulnerabilities, and that the ability to inspect the source means you’ll never install anything nefarious.
I expect all of them to have read the source for every single package they’ve ever installed. Oh and the Linux source too, of course
Another classic lie. ‘Open source’ misses the point of libre software. Anti-libre software [malware] bans us [everyone else] from removing malicious source code.
The whole point is that at some point somebody can check, and you can have a higher level of trust in that than proprietary software.
And if someone does something like this then it has to be disguised as an innocuous bug, like heartbleed, they can’t just install full on malware.
It’s a different beast entirely.
‘Open source’ misses the point of libre software.
They used to be synonymous. Of course now we have conbtributor licenses
It was invented to derail libre software.
You’re right, I should clarify better. When I say open source, what I mean is totally open and totally free to contribute to, like the MIT or patchy licenses. Source viewable is a whole different can of worms and not what I mean, so I should be more specific in future.
Contributing isn’t the point. AGPL helps us keep control of our own computing.
I’ recommend to just read the report https://www.zscaler.com/blogs/security-research/technical-analysis-anatsa-campaigns-android-banking-malware-active-google
Hello EVERYONE here’s a list of 50 unbelieveable products that will change your life and grant you immortality:
Am I just missing it, or is there no list of of these infected apps on the posted article or the reference the article links to. To me, that is the most important information.
It is about halfway down the article, but you have to dodge a few adds to get to that part.
“The two apps mentioned in the report were called “PDF Reader and File Manager” by Tsarka Watchfaces and “QR Reader and File Manager” by risovanul.”
Well, I did miss that, I was skimming for something like a large list or table. That still leaves 86/90+ unlisted.
Can’t steal my bank info if I use cash only…
You’re only robbing yourself if you go cash only. $1 will be worth less tomorrow than it is today.
The $1 in your scam account is worth the same as a real $1 bill. Maybe less when the entire financial system inevitably collapses in on itself as the rest of the world does and people will actually value real money again.
If that actually happens money is literally just paper at that point.
The $1 in my account actually grows. Sorry you don’t understand basic finance.
It “grows” because you don’t own it and these scamming places want to encourage you to “invest” in their scam. It’s like investing in any other scam. At the end you can be screwed over by all these banks – as I have so many times because they don’t care about me or my money – and decide to destroy every bit of savings I have because of some “error” that they ultimately blame on me.
No thank you. I have been scammed by banks (and credit unions) far too many times in my life. They’re just greedy, hateful businesses, like any others, and you shouldn’t trust them. Just part of our capitalist nightmare.
Damn dude. You really have no clue. You lend the bank your money. They can use that money to lend to others. They give you some of the profit.
If you deposited money in a bank, and they told you it’s now their money and you own nothing, then you didn’t deposit money in a bank.
You are clearly leaving out important details. Banks can’t just take your money.
The fact that it seems to have happened multiple times to you is extremely suspicious.
They have. Multiple banks and a credit union. Mismanaged my money and screwed me over while I was trying to get it right leading to owing them huge fees and ultimately no money in the account. Never again.
But just keep throwing money at the scam and have every single store track your purchases by your credit card. I refuse to participate in such a nightmarish society.
Again, I believe you are leaving out key details. They didn’t just take your money.
My assumption is that you didn’t understand how banking fees work and overdrafted your account or something. Perhaps got a credit card and only made minimum payments, which essentially just covers the interest.
How though. Over here cash isn’t accepted anymore at most places. I only use cash for buying drugs. Most stores and groceries only accept card. Same with bars and clubs. I honestly have no idea besides drugs what to use cash for.
I cannot imagine such a dystopian, nightmarish place where you can only pay with something that personally identifies you. Congrats for living in a nightmare. I’d leave.
Yeah, sure, where to? I live in the Netherlands, one of the wealthiest countries. I’ve seen many parts of the world in my time in the navy. There aren’t many places better then here, honestly. Only Norway scores higher, they have a lot of things worked out much better then the rest of us. But paying with plastic is very common there too. Also, digitalization doesn’t have to be bad. Look at Estonia, I think many countries can benefit from their system. See here a video on it by Kraut. There’s a difference between digitalization and a system like China has. But my expenses should be private at least, so cash would be best. They just make it harder every day. We used to be able to say “I’m not interesting, no one cares what I do, no one is going to check me”. But now we have AI, now every one of us indeed IS interesting. And everyone is being checked to teach the algorithm. Countries with few laws to protect privacy and welfare of it’s inhabitants, like the US for example, can turn to a totalitarian control state in no time with just one crazy idiot as a leader. At least the US never had idiots as president 👀. At least the US doesn’t have a history of wanting to collect everyone’s data 👀. At least they are not actively doing anything with the data, like China or Russia does 👀.
But on your point of living in a dystopian world: Yeah, we fucking do. But it doesn’t matter where we live. It’s dystopian everywhere. We live in World War III while we have to fight to get the bare minimum of privacy, we must work our ass off for the bare minimum of living standards and we buy products we do not own. Difference between the rich and poor has never been as high as now and the military strongest countries are run by idiots and dictators. Mass amount of people see Elon Musk as our savior for a better future, the biggest narcissistic hypocritical scam artist our there. At least Trump isn’t president anymore. Oh wait… Seriously, the movie Idiocracy isn’t a comedy, it’s a documentary. I seriously think the US would benefit if it had Dwayne Elizondo Mountain Dew Herbert Camacho as president over Trump.
While the rest of the world turns more extremist every day (especially right wing) with rising world tensions.
So if I plan on moving it will be out of the world of the living at best.
It’s funny how in our dystopian America (and I agree, it is), at least we can still pay for things anonymously.
What a concept.
These articles are useless without a damn list
Right
