- 0:00On July 14, 2026, the FBI arrested
- 0:02Siire don Tevius Samarion Wilkins,
- 0:05accused of distributing malware in
- 0:07Steam video games and infecting nearly
- 0:108,000 devices. During the nearly 2
- 0:13years this operation lasted, from May
- 0:152024 to February 2026, the
- 0:17cybercriminal stole $ 220,000 in crypto
- 0:19assets, according to the criminal
- 0:21complaint. The big question, then, is
- 0:24how did this happen if Steam has a
- 0:26review process and various controls?
- 0:28The truth is that neither Steam nor any
- 0:31other official download platform is
- 0:33infallible, and criminals know it. That
- 0:35is why they try to infiltrate those
- 0:37ecosystems, because they know they have
- 0:39something key and very valuable there:
- 0:40the trust of users.
- 0:42Connecting, connecting.
- 0:45Conexión Segura, the ESET Latin
- 0:47America podcast, your direct link to
- 0:49the world of cybersecurity.
- 0:53Hello everyone, welcome to a new
- 0:55episode of Conexión Segura. My name is
- 0:58Cristian Alibrando, and well, we are
- 0:59here as always; if you clicked play, we
- 1:01are here to talk about a topic linked
- 1:02to cybersecurity, but today we are
- 1:04going to talk about something more
- 1:05regarding trust. Specifically, about
- 1:09the trust that we as users often place
- 1:11in official download platforms and that
- 1:14perhaps can put us in a bind. Yes, in
- 1:18fact, a recent arrest made by the FBI
- 1:20reveals how a cybercriminal managed to
- 1:23sneak into an official platform like
- 1:25Steam. an infected video game and thus
- 1:29infect more than 8,000 computers and
- 1:31obtain various financial gains. Do I
- 1:34mean by this that you should no longer
- 1:36download applications from these
- 1:38official platforms? No, not at all. The
- 1:42advice will always be to use those
- 1:44repositories, but what we are going to
- 1:46analyze is why some of these controls
- 1:48are not infallible and why we should
- 1:50not trust 100%when we are downloading
- 1:52something, even if it is from an
- 1:54official platform. But to analyze this,
- 1:58I am not alone; I don't know, I don't
- 2:00want to say you are a guest because you
- 2:01are already part of this house. Mario
- 2:03Mikuchi, security researcher for Latin
- 2:05America. Well, Mario, a very important
- 2:08and everyday topic. We are going to
- 2:10analyze today
- 2:11an important topic, an everyday topic
- 2:14that involves all of us users who use
- 2:18mobile devices, basically, right? Uh,
- 2:23and that we use uh platforms in general
- 2:26, I mean, all users, basically.
- 2:28Totally. It is a general topic that
- 2:30impacts us daily. So well, specifically
- 2:33today what we are going to analyze is
- 2:35how cybercriminals manage to perhaps
- 2:37sneak a malicious application into an
- 2:39official repository. Why can't an
- 2:43official store guarantee that what is
- 2:45there is 100%reliable? And obviously,
- 2:48as users, what can we do in this
- 2:50scenario? So, well, without further ado
- 2:53, let's start the episode.
- 2:55For more information about today's
- 2:57episode, visit our website
- 2:58eset.com/atam. You can also visit our
- 3:02cybersecurity blog.
- 3:03welivesecurity.com/en.
- 3:09Well, Mario, and I apologize to the
- 3:11whole audience, sorry if I'm being
- 3:13repetitive, but in this first section,
- 3:15I want to make it clear that the advice
- 3:17was, is, and will always be to download
- 3:19any type of application and software
- 3:21from official repositories. Yes, I want
- 3:24to make this very clear. Now, what we
- 3:26must not confuse is that it is the
- 3:29safest option; we must not confuse it
- 3:31with it being infallible. Right,
- 3:35because although any type of official
- 3:37repository like Google Play, Apple
- 3:40Store, or even Steam, they have their
- 3:42controls, those controls are not even
- 3:45close to a real security audit. So, it
- 3:49will never be infallible. What I want
- 3:52to ask you, Mario, taking advantage of
- 3:54your expertise, is where does the flaw
- 3:56in this review process lie? Or what is
- 3:58it that the initial review process that
- 3:59these platforms have can detect and
- 4:01what things can they not? Okay. Well,
- 4:05in principle, there is no single way in
- 4:08which these review processes are
- 4:10carried out. Let's say it depends on
- 4:14each of the developers who upload the
- 4:17applications. It is not the same as
- 4:20someone who has their first application
- 4:23to upload, whether we are talking about
- 4:26the App Store, Play Store, or
- 4:28marketplaces in general, because that
- 4:31also includes Steam and so on. In this
- 4:35case, the processes are slow because
- 4:38the platforms verify the reputation of
- 4:40this new developer. However, the
- 4:44developer goes through a lot of
- 4:46bureaucracy, let's say, fiscal, etc.,
- 4:49because they also validate their
- 4:52country of residence, if they invoice
- 4:55or not. Well, this is like a particular
- 4:59case that we are talking about, new
- 5:01developers, so to speak. In the past,
- 5:04you only needed to have an account, for
- 5:06example, on the App Store or Play Store
- 5:08when talking about mobile applications,
- 5:09and you could upload the app. Well,
- 5:11that changed because today if one wants
- 5:13to be an official developer, you have
- 5:15to get involved in a whole program and
- 5:17so on. Now, assuming that the developer
- 5:21already has a reputation and a track
- 5:24record in the world of application
- 5:26development uploading to the stores,
- 5:29well, the processes are more lax, so
- 5:31they focus more on the reviews of the
- 5:34applications themselves.
- 5:38And, well, they are done a bit more
- 5:40quickly. Why? Because the developer
- 5:43already has a reputation that validates
- 5:45them, right? Which doesn't mean that,
- 5:49well, someone might perhaps do their
- 5:52homework for a while, only to upload
- 5:55malicious code or applications with
- 5:58suspicious behaviors once they've
- 6:01reached that reputation, we could say,
- 6:04right? So, given this situation, what
- 6:08the platforms do is validate, well,
- 6:11whether the uploaded applications have
- 6:15malicious code, if they respect the
- 6:17terms of the privacy policy; the
- 6:20various marketplaces also validate the
- 6:23type of content that these applications
- 6:27will process. When we talk about the
- 6:30type of content, we are talking about,
- 6:33well, age rating, meaning that, for
- 6:35example, if there is a device that is
- 6:38configured to be used by minors,
- 6:41well, on that device, an application
- 6:44that doesn't, let's say, respect the
- 6:46content rules, won't be able to be
- 6:49installed, right? In other words, there
- 6:54are several checks that are performed
- 6:59regarding, let's say, the generation of
- 7:03new applications, right?
- 7:05Very well. In fact, why do we say that
- 7:07this initial control you just detailed,
- 7:09Mario, is insufficient? Apple, last
- 7:12year, in a report it released regarding
- 7:15what was 2025, acknowledged having
- 7:17removed almost 60,000 applications that
- 7:19, at first, seemed legitimate, that
- 7:22initially had passed all the checks,
- 7:24and that they, after subsequent reviews
- 7:26, realized were software that actually
- 7:29intended to commit financial fraud. So,
- 7:32does this mean that Apple and Google
- 7:34Play are insecure, right? But the
- 7:37review process is not perfect, it's not
- 7:39infallible, because an application can
- 7:41have a certain behavior that seems
- 7:43legitimate and real at one moment, but
- 7:45then change it later. And that's where
- 7:48I want to introduce, Mario, what we are
- 7:50going to see in the next section: the
- 7:52term "bait and switch," which I think
- 7:54is a bit of what will explain to us how
- 7:56cybercriminals manage to sneak an
- 7:57application into official repositories.
- 8:03Well, the term "bait and switch" is
- 8:05currently used to describe that
- 8:07technique we were just talking about,
- 8:09where an application presents itself as
- 8:11legitimate and, let's say, authentic
- 8:13during the platform's validation
- 8:15process, but then changes its behavior.
- 8:19In other words, to put it plainly, the
- 8:21"bait" is the app that presents itself
- 8:23as good, as something that will deliver
- 8:25what it promises, and the "switch" is
- 8:28when the change happens. Mario, what is
- 8:30that change about? How can malicious
- 8:33developers make that change? How do
- 8:35they manage to do it on a more
- 8:37technical level? Let's say,
- 8:39well, it's simply about incorporating
- 8:43these new malicious functionalities
- 8:46through the updates that are made
- 8:51to the applications, right? As you
- 8:55correctly say, the cybercriminal's
- 8:57first step is to earn the store's trust
- 9:00, for the store to consider them a,
- 9:02well, a legitimate developer free of
- 9:08fraud, basically, right? Once this is
- 9:12achieved and the cybercriminal can
- 9:15finally upload the app, well, it is
- 9:18well known that apps are constantly
- 9:21regenerating because they incorporate
- 9:23new features, fixing bugs; that is,
- 9:26they are also, uh, fixing security
- 9:29issues, let's say, in the traditional
- 9:32world, right? And this is where the
- 9:36cybercriminal takes advantage of these
- 9:39modifications to, well, change the
- 9:42rules of the game and add, well,
- 9:44perhaps, let's say, fraudulent
- 9:47behaviors, right? Which can, that can
- 9:51obviously range from, uh, establishing
- 9:54communication with external servers
- 9:57that download files to the device, or,
- 10:00uh, espionage. That is to say, there
- 10:06are multiple options that can occur in
- 10:09this situation of, well, installing an
- 10:12update. And what is important to
- 10:15highlight is the difference in the
- 10:17review processes. We were talking
- 10:20before about how the different, uh, uh,
- 10:25platforms carry out reviews that are,
- 10:28of course, very far from performing a
- 10:30penetration test audit, for example;
- 10:32they are not, it is a review
- 10:34That is done, in general terms, we
- 10:37could say, uh, that verifies the
- 10:39essentials, and when updates are made,
- 10:42a bit of the same thing happens, only
- 10:45the review times change. And well, uh,
- 10:50the problem is, as you rightly said,
- 10:53that the cybercriminals for those, uh,
- 10:56platforms, well, uh, are legitimate,
- 10:58they earned their trust, and so on,
- 11:01right?
- 11:02Anyway, well, going back to, let's say,
- 11:05the example of Apple, which we said
- 11:07acknowledged having removed 60,000
- 11:09fraudulent apps that initially did pass
- 11:11that first check. Well, what Apple also
- 11:15does is continue verifying the
- 11:17different apps, and if there is a new
- 11:19update, what Apple does is compare
- 11:21version 1.0 with 1.1. I mean, platforms
- 11:24are already incorporating this, I don't
- 11:26know if it's a second stage of review,
- 11:28but they are expanding the review
- 11:29process a bit. And Google perhaps
- 11:31doesn't talk about concrete data like
- 11:34Apple does, but Google does. Through
- 11:36Google Play Protect, what it ensures
- 11:38are instances of subsequent reviews
- 11:40even after an app has been approved,
- 11:42and clearly, if they are conducting
- 11:44subsequent reviews, it's because the
- 11:46app can change. So today, is it a
- 11:49challenge that these types of platforms
- 11:51face, the fact of perhaps adding more
- 11:53controls, reviews, I mean, is it really
- 11:55a challenge for these platforms?
- 11:59Without a doubt it is, and the
- 12:01differences are perhaps biased by the
- 12:04type of operating system on which the
- 12:07applications are, let's say, going to
- 12:09be installed. iOS is a very different
- 12:14operating system to, let's say, Android
- 12:17basically, right? Already, in and of
- 12:23itself, well, iOS has a very different
- 12:25security structure; so, that is why
- 12:28there is a difference in the protocols
- 12:30for carrying out the verifications. But
- 12:34it is a fact, the need to verify the
- 12:37differences between versions, eh, and
- 12:39well, and to increasingly apply more
- 12:42layers of security, even at a physical
- 12:45level, because every time new, um, new
- 12:50devices come out. Basically, in the
- 12:52case of iOS, we understand that, well,
- 12:54it is Apple who develops these devices.
- 12:58They are constantly adding security
- 13:00layers at the hardware level, that is,
- 13:02when applications are signed, well,
- 13:04they are verified at the hardware level
- 13:07to see if the certificates are
- 13:09compatible, if not, if they are
- 13:11legitimate. And in the case of Android,
- 13:15where obviously a range of device
- 13:18brands will come into play, eh, it is
- 13:21also seen how these security layers are
- 13:24being applied more and more. Eh,
- 13:28although we have to assume that
- 13:30security is always relativized by this
- 13:32factor that we mentioned before, which
- 13:35is trust, right?
- 13:40Everything we have been recounting in
- 13:42the previous sections, eh, we can
- 13:44perhaps anchor and develop through a
- 13:46real and recent case that happened very
- 13:48shortly ago. I'm going to read a bit
- 13:50here because there are difficult names.
- 13:54Well, in July of this year, Sairebius
- 13:56Samario Wilkins was arrested by the FBI
- 13:59because he was accused precisely of
- 14:01distributing an info stealer through
- 14:03video games that he managed to get
- 14:05published on Steam. Yes, this campaign
- 14:09itself lasted almost 2 years, from May
- 14:112024 to February 2026. In the process,
- 14:15he infected more than 8,000 computers
- 14:18and stole $ 220,000 in cryptocurrencies
- 14:20. Yes, I also want to read the short
- 14:23list here to be clear. Uh, the FBI saw
- 14:27that these video games are being
- 14:29distributed on platforms like Telegram
- 14:31and Discord, and we are talking about
- 14:34games like Blockblaster, Chemia, Dash
- 14:36FPS, Lampi, Lunara, and a few others. I
- 14:41mean, and although some details about
- 14:44this specific campaign are unknown,
- 14:46similar ones allow us to understand
- 14:49that the malicious actor managed to
- 14:51pass the initial checks so the games
- 14:53would be published on Steam. They
- 14:58published them, let's say, they spread
- 15:00them through these channels like
- 15:01Discord, Telegram, and others. And once
- 15:04the person, the victim, downloaded the
- 15:06game, they were immediately executing
- 15:09the malware. And on top of that, as an
- 15:12extra detail, which is also in the
- 15:15FBI's criminal complaint, the
- 15:17cybercriminal used chatbots to detect
- 15:20some victims with lucrative
- 15:21cryptocurrency wallets. So I say: it is
- 15:25a quite interesting case. I hope I
- 15:28pronounced the names correctly, but
- 15:30well, what we want to convey with this
- 15:32specific and current case is that the
- 15:34validation processes of platforms like
- 15:36Steam, which is one of the biggest in
- 15:38video games, are not infallible, and
- 15:40today cybercriminals don't really try
- 15:42to convince you, as a victim, to
- 15:44download an .exe, but rather to
- 15:46download an application. It is much
- 15:49simpler. Today, today cybercriminals
- 15:51are abusing this trust. But Mario, to
- 15:53go a little further, we are always
- 15:55talking about applications, but it
- 15:57seems to me, or rather, I want to ask
- 15:59you, the scenario is a bit broader
- 16:01because, can we include extensions,
- 16:03plugins, mods, and cheats in this? I
- 16:05mean, can all these types of software
- 16:08also be used to distribute malware,
- 16:10right?
- 16:11Exactly, exactly. As you rightly say,
- 16:15we don't have to limit the context to
- 16:18the mobile universe; we were mentioning
- 16:21the marketplaces of, well, the App
- 16:24Store or Play Store, which are the
- 16:27popular repositories where one is
- 16:29downloading applications all the time,
- 16:32right? Yes.
- 16:35But as you say, there is the gamer
- 16:38universe, which is currently
- 16:40popularized by the Steam platform, and
- 16:43in turn, the universe of plugins or
- 16:46add-ons that we use in browsers as well
- 16:49. Yes. We recently published a post on
- 16:52WeLiveSecurity, and I personally had to
- 16:55analyze a Chrome extension that
- 16:57promised to be a security tool, and
- 17:00instead, it was an info-stealer, that
- 17:03is, malicious software that steals
- 17:05credentials, right?
- 17:07Exactly. This leads us to, uh,
- 17:11double-check our attention when
- 17:14downloading software from the various
- 17:17platforms, even if they are official.
- 17:22Yes. Uh, because, well, we can never
- 17:25rule out everything we've been
- 17:27mentioning, right? Now that we
- 17:31understand that criminals can manage to
- 17:34gain trust and reputation in these
- 17:36applications and upload, well,
- 17:39different versions, let's say, of code
- 17:41that may have fraudulent activities,
- 17:44that is where, well, we have to pay
- 17:46more attention and not limit ourselves
- 17:49to one context, as I said before, which
- 17:52could be the mobile world, but whenever
- 17:55we have to install applications,
- 17:58double-check, well, the verification of
- 18:01the sources and so on, right?
- 18:04Well, without meaning to, you're almost
- 18:05setting me up for what we're going to
- 18:07talk about in the next section.
- 18:08Great. Well, as we were just saying,
- 18:13there is a big question that might
- 18:15serve to open this section, this new
- 18:16section, which is: how can we protect
- 18:18ourselves? We are presenting a scenario
- 18:22that is quite, let's say, worrying and
- 18:23real. So, well, perhaps a very good
- 18:27answer at first is a security solution.
- 18:31And I justify it, as they told us when
- 18:33we were studying, and I justify it
- 18:35because if official stores today have
- 18:37an initial security check, it is what
- 18:39we talked about: they check the
- 18:40application in question at that
- 18:42specific moment and then, what happens
- 18:44after, is kind of lost. Well, what a
- 18:47security solution allows today, thanks
- 18:49to advances in technology and the
- 18:51layers that the security solution
- 18:52involves, is to say, well, today this
- 18:54app is doing this, but I am going to
- 18:56monitor what it will do tomorrow, what
- 18:58it will do in 6 months. So, I want to
- 19:01bring it down to earth so it's
- 19:02understood. Although the security
- 19:05solution says: "Great, I know this app,
- 19:08it was approved, it is acting well," if
- 19:10in 6 months that app starts asking you
- 19:13for strange permissions, doing some
- 19:15behavior out of the ordinary, to this
- 19:17that you were saying, requesting
- 19:19connections with external servers and
- 19:22so on, well, it is the security
- 19:24solution that will sound the alarm for
- 19:26you. It is like a very good defense for
- 19:29this term we were just mentioning, the
- 19:31bait-and-switch. So, specifically,
- 19:34Mario, since with your expertise and
- 19:36technical background you'll explain it
- 19:38much better than I can, what exactly
- 19:40can a security solution detect that
- 19:43will help us if, at first, we thought
- 19:45we were installing a real and
- 19:46legitimate application, but then we say
- 19:49, "Hey, wait, it's doing something
- 19:51different now." It either wants to
- 19:54steal your cryptocurrency or it wants
- 19:56to install malware. I mean, what are we
- 19:58going to say? What specific warning
- 20:00signs can a security solution detect?
- 20:03Well, in principle, it's the behavior,
- 20:06right, of the applications.
- 20:10And often this behavior is biased by a,
- 20:18let's say, a, yes, a situation of
- 20:20privilege abuse in the system, as you
- 20:23rightly say, right? It asks you for, I
- 20:26don't know, confidential information or
- 20:29credentials all the time, et cetera.
- 20:32What is important to understand is that
- 20:35there isn't just one single
- 20:37cybersecurity solution that we can use
- 20:40on our device.
- 20:42There are basic solutions, that is,
- 20:45they detect malware; in the presence of
- 20:49malicious code, the solution will
- 20:52directly, well, quarantine that
- 20:55application or delete it outright. This
- 20:59depends on how we configure it, right?
- 21:02But then we have applications that come
- 21:05with add-ons, right? Where we can
- 21:08detect, for example, phishing, we can
- 21:10detect, I don't know, situations
- 21:12related to browsing malicious sites and
- 21:15that type of situation. Yes, it's
- 21:19important to highlight that in security
- 21:21, we have to bet on a layered model.
- 21:24Yes. To say that
- 21:26the security solution isn't going to
- 21:29solve all our problems; basically, we
- 21:32have to think of it as one more layer
- 21:35of security. We talked about how app
- 21:39stores have their own security systems.
- 21:42Well, that is the first line of defense
- 21:44when downloading an application. Well,
- 21:48then the other is our own behavior as
- 21:53users. Then we have the solutions we
- 21:58are highlighting, right? Meaning that
- 22:01if one of the layers fails, we have
- 22:03contingency with another that can, well
- 22:06, reverse a cybersecurity problem. But
- 22:10focusing on cybersecurity applications,
- 22:13it is important to consider them
- 22:15because they won't just protect us when
- 22:18downloading potentially malicious
- 22:20software, but it's about the entire
- 22:23context of the device. Uh, I don't know
- 22:27, if we are trying to connect to a
- 22:29public network, well, the security
- 22:31solution will limit access because it
- 22:33understands that you are connecting to
- 22:36Wi-Fi at an airport or a café. Right.
- 22:40If you are looking at emails, well, it
- 22:43will automatically detect if, well,
- 22:46it's talking about potential phishing
- 22:50or a fraudulent site. If you are
- 22:54downloading attachments, for example,
- 22:57from messaging systems, whether it’s,
- 22:59I don't know, WhatsApp or even social
- 23:01media messaging systems, well, that
- 23:04attachment will also be intercepted and
- 23:06analyzed by the solution. Meaning the
- 23:09solution is holistic, that is, it is
- 23:11integral across all layers of the
- 23:13system, right?
- 23:15Well, Mario, I’ll take that last
- 23:16concept of layers because we’re going
- 23:17to talk about that in the next section,
- 23:19but I think that’s where you’re
- 23:20headed. I mean, a security solution
- 23:23might not guarantee 100%of everything,
- 23:25but it will undoubtedly add certain
- 23:27necessary layers to build upon other
- 23:29actions we’ll review in the coming
- 23:31section, which are just as important as
- 23:33the ones we just went over. Well, as is
- 23:39usual in our episodes, the idea is
- 23:41always that those who listen to us take
- 23:44away, I don't know if a toolkit, but at
- 23:46least some useful tips for daily life,
- 23:49so their digital life is increasingly
- 23:51secure. And well, obviously this
- 23:53won’t be the exception. And well, I'm
- 23:56going to be repetitive today, but the
- 23:58first piece of advice we give is: keep
- 24:00downloading any type of application
- 24:03from official repositories. That is key
- 24:06. Uh, obviously I think the most
- 24:09important invitation is to distinguish
- 24:11between it being the safest option and
- 24:13it being infallible. They are two
- 24:16different concepts, but from our side,
- 24:18the advice will always be to download
- 24:20from official sources, read reviews,
- 24:22comments from other users, because I
- 24:24think that is perhaps the best
- 24:26yardstick to understand if we are
- 24:28looking at a truly legitimate app or
- 24:30not. And obviously, always avoid
- 24:34downloading pirated software, cheats,
- 24:37and the like from non-official
- 24:39repositories. Mario, while I have you,
- 24:41I want to take a walk down memory lane
- 24:43or take a trip to the past. The last
- 24:46time we chatted, we talked about
- 24:48hacking emotions, about, well, issues
- 24:49clearly linked to the emotional, and I
- 24:51think this, this episode also goes
- 24:53hand-in-hand because trust is at stake,
- 24:55which is also something that you have,
- 24:57that you earn, or that you don't. I
- 25:00mean, and it's, it's very interesting,
- 25:02and I say: the invitation is perhaps
- 25:04for us as users to change our mindset
- 25:06and say: "Yes, let's see, it's a good
- 25:08decision to keep downloading from
- 25:10official apps, uh, platforms, sorry,
- 25:12but I don't have to deposit all my
- 25:15security there, right?". And I think
- 25:17that's an invitation for this episode.
- 25:19It could go that way, right? It's more,
- 25:20it's more emotional the
- 25:22exactly, it's, uh, it's exactly as you
- 25:25say. In fact, to be even more general,
- 25:31any cyberattack in its life cycle has a
- 25:35trust violation factor. I mean, we can
- 25:40even see, uh, I don't know, 70%of
- 25:43attacks have a social engineering
- 25:46technique involved in their life cycle
- 25:49that violates a user's trust. Yes. And
- 25:53that we have to start reviewing most of
- 25:55the techniques that are used. Well, uh,
- 26:00there's always, let's say, the value of
- 26:03, of, of trust, of the violation of
- 26:05trust as a radical element for any
- 26:08cyberattack to be successful, right? So
- 26:13, well, regarding what you're proposing
- 26:16to me, which makes perfect sense, uh,
- 26:18when we go to download an application,
- 26:21as you rightly say, we have to do it
- 26:23from an official repository. But if,
- 26:27after finishing the download, we open
- 26:30the application and we're talking about
- 26:33a calculator that suddenly starts
- 26:36asking for access to the camera, the
- 26:38Bluetooth, and a bunch of permissions,
- 26:41well, uh, something doesn't add up.
- 26:44Be, be alarmed.
- 26:46Right, there's something that doesn't
- 26:47make much sense, does it? Why would a
- 26:49simple calculator ask me for access to
- 26:52my contact list, for example?
- 26:54Totally.
- 26:56And so on with the type of, I mean, or
- 26:58the different types of applications
- 27:00that we are going to download, right?
- 27:03It's about having, uh, common criteria,
- 27:06yes? uh, common sense when starting to
- 27:11interact with applications that, well,
- 27:13often require these types of
- 27:15permissions, which in many cases are
- 27:18justified, but in many others are not.
- 27:22And that is where we have to pay
- 27:23attention. The same as we said before,
- 27:26it could be that we download a perfect
- 27:29application and then, I don't know,
- 27:31when we go to perform an update, that
- 27:33update suddenly comes with strange
- 27:35little things that ask for new
- 27:37permissions, and why does this
- 27:39application now ask for permissions
- 27:41that it didn't ask for before? Yes. So,
- 27:45having that common sense, right?
- 27:48Totally. Well, looking at the path
- 27:50we've been taking, I was thinking, we
- 27:52shouldn't just rely on saying, "Well, I
- 27:54downloaded it from an official
- 27:55repository," as that might be just the
- 27:57first step of control. Saying, okay, I
- 28:00got the first step right, which was
- 28:02downloading it from an official
- 28:03platform. Now, the second is to always
- 28:06keep an eye on what we said about how
- 28:08the application behaves. Whether what
- 28:11it's asking for is logical, if what
- 28:13it's proposing makes sense with what it
- 28:15does. Mario, you just gave me some tips
- 28:19to keep in mind, but I mean, what other
- 28:21things or what other strange behaviors
- 28:23should catch our attention as users? I
- 28:26think the example you gave about the
- 28:28calculator is great, like, why is it
- 28:30asking for this? Beyond that, is there
- 28:32any other alarm or signal that allows
- 28:34us to identify and say, hey, this isn't
- 28:36right, this isn't correct? Well, in
- 28:40principle, it's the behavior, right?
- 28:42What we mentioned before.
- 28:45Then it's important to understand that
- 28:47applications are dynamic, they are
- 28:49organic, meaning an application is
- 28:51changing all the time. Yes. We might
- 28:54tend to think that WhatsApp is just
- 28:57WhatsApp, but WhatsApp is actually
- 29:00changing all the time because with
- 29:03every new update, we basically have a
- 29:06new application.
- 29:07Totally.
- 29:08Right? That adds features or removes
- 29:11features. That is, this warns us that
- 29:16with every new update, every new
- 29:20download, well, we are facing a
- 29:24scenario that merits some, well,
- 29:29consideration. In principle, what we
- 29:32can detect most is, as we said before,
- 29:34behavior. Yes. Well, precisely the
- 29:38permissions it asks for. Then we can
- 29:42look at other subtleties that have to
- 29:44do with saying, "Ah, after I installed
- 29:46this app, the device runs slower."
- 29:49No, that's more useful.
- 29:51Right. But well, it's still a situation
- 29:54we have to notice, or after installing
- 29:57this, my battery doesn't last at all.
- 30:00Or the phone consumes more data, for
- 30:03example,
- 30:03or it uses more data, right? So, those
- 30:05are things that should make us
- 30:08suspicious. Of course, the context
- 30:11changes if we already have a security
- 30:13solution on the device or not.
- 30:17Uh, because the security solution can
- 30:19start, it can warn us, right? Well, if
- 30:23this is, uh, strange, or if it’s
- 30:26malicious code or a fraudulent
- 30:29application, the solution can take
- 30:32action directly. But today we still see
- 30:36that a number of users don’t have
- 30:38security solutions on their devices. So
- 30:42, in a context like this, you have no
- 30:45choice but to say, "Okay, let's analyze
- 30:48using the metrics that devices give us
- 30:51today, which application is consuming
- 30:54the most, I mean, consuming space,
- 30:57consuming data." We can check the
- 31:02activity of each one, but that is
- 31:04undoubtedly a tedious task, especially
- 31:07for people who aren't technical and
- 31:09aren't interested, which they have
- 31:11every right to be.
- 31:14Where I think we conclude on the
- 31:16importance of having security solutions
- 31:19, right?
- 31:20Very well. So, as a summary, I’d like
- 31:23to say that to be, I don't know if
- 31:25prepared, but at least much safer in
- 31:28this scenario, first, always download
- 31:30from official repositories. Second,
- 31:34don't trust the initial installation
- 31:36100%, but always keep an eye on what
- 31:39the app is doing, and obviously, in
- 31:41what you said, keep our device
- 31:43protected, whether through a security
- 31:45solution or by keeping it updated. I
- 31:48think with that combo, returning to the
- 31:50idea of multiple layers, we can
- 31:52significantly reduce the risk of being
- 31:54surprised by a malicious one on our
- 31:56phone.
- 31:57Absolutely. Well, to close this episode
- 32:02, we want to reinforce the golden rule
- 32:05again, which is that any type of
- 32:07application and software you download
- 32:09must be downloaded from official
- 32:11repositories. Now, the invitation is
- 32:14not to confuse the fact that an
- 32:17official download platform is the
- 32:19safest with it being infallible. So
- 32:23also, as users, we have to do our part
- 32:26with follow-up checks, having a
- 32:28security solution, and being attentive
- 32:31to the updates the device requests;
- 32:34because, as we said, today,
- 32:36cybercriminals no longer want to
- 32:38convince you to install malware, but an
- 32:41app. So, we have to be alert because
- 32:45they continue to exploit trust today
- 32:47through these new methodologies, and I
- 32:49always say, cybercrime is always
- 32:51looking for new ways, and we have to
- 32:53update ourselves too; we can't stick
- 32:55with how things were a decade ago. So,
- 32:58well, that is the invitation. Mario, as
- 33:00always, thank you. Like I always say,
