Smartphone virus: what are they and what to do?
It must have happened, at least once, to everyone in their lives, to bump into a smartphone virus, capable of putting your smartphone operative system in crisis.
Nothing too serious, if you manage to stop the problem in time, while it can be very risky, if you don’t recognize the problem soon enough.
Anyway, instead of running for cover, it’s always better to prevent and, most of all, to be informed about the possible threats that lurk around your smartphone.
Nowadays, everyone has at least one smartphone, tablet or mobile device, always on hand, and more rarely we limit ourselves using them as tools to communicate, or to play, but, they became real information and personal data collectors, and so a fast lane for who wants to access to your life and your online identity, improperly.
As a matter of fact, we more often have sensitive data on our devices, such as personal information, details for the access to the social media and, in many other cases, also the related one about mobile apps of bank accounts and credit cards.
There is nothing more comfortable and useful for everyday life, but the profeeters are lying in wait, and being unprepared is a risk that you cannot afford.
It’s always better to know what problems you could face, in order to prevent them and to reduce the most the possible impact on your safety and privacy.
In consideration of the fact that the smartphones are taking over the PC in the daily routine, we have to take into account the consequent growth that these are having, as well as being targets for hackers and online scammers.
Let’s see together what are the potential threats from which we want to protect ourselves, and some suggestions on how to not get serious damages.
Threats for smartphone
The specific malware for smartphone are spreading and are getting used, even more and more.
These damaging softwares can be transmitted in many ways: contaminated web pages, vicious apps, email, SMS, Bluetooth, socials and WiFi networks.
Just because of their versatility, in order to protect yourself,, it’s important to have a good mobile antivirus, to avoid installing not reliable apps and to not trust the app in the Google Play Store as well, that sometimes can be dangerous for your privacy.
Public WiFi networks, very often, use low efficient safety measured, sometimes not even that!
When you use encryption systems of transmissions that are too weak, or when there are none , smartphones that access to these nets are exposed to the things called Man in the middle Attacks.
In the specific, this kind of attacks are done by hackers that are nearby and take possession of the device we are talking about.
In order to avoid this inconvenience, our suggestion is to avoid public or open connections, and to prefer the virtual private ones, also called VPN
We have already talked about phishing as a matter of online scams, that’s why we can’t consider it just a problem concerning smartphones.
In fact, the phenomenon can be found on any device, but for sure, the mobile ones broaden the possible options of who act through phishing campaigns.
If we are used to the traditional mail phishing, which can be done on smartphones as well, the possibilities broaden when we’re talking about mobile devices, reaching the contemplation of the cases where the dangerous links are sent and shared through SMS or instantaneous messaging, such as WhatsApp, Viber or Telegram.
In that case, the best weapon is common sense: open your eyes and beware of suspected links.
Always try to recognize what source the message comes from, who’s the sender and, most of all, if they’re really who they say.
So, be careful!
Personal data theft
A data theft happens when there’s an access to your data from unauthorized subjects.
This happens mostly throughout the many installed apps on a device: at the moment of the installation, indeed, it is required to insert things info and to give consent to a series of authorizations needed for the functioning of the app we are talking about.
In the majority of cases, personal info, access details and info related to the credit cards are requested.
Nevertheless, if a hacker can violate the developers servers of these apps, they can easily get the data inserted in them.
That’s why, in order to defend yourselves from that risk, we suggest you to limitate the apps number on your device to just the ones you really need and, when it’s possible, to avoid giving them access to your personal data.
Calls from Tunisia
This is the latest phenomenon: calls from Tunisian numbers: if it happens to you, you better know that’s a scam!
The scam that’s spreading is the one about received calls with a Tunisian prefix +216; it’s usually just a ring, after which the caller hangs up immediately
Why calling and hanging up immediately after that?
Easy: to induce the user to call that number back, because it is connected to a hacker server, which empties, in a few seconds, the bank account of the ignoring user, or activates monthly payments.
Moreover, the Tunisian telephone number changes every time, so that, even if it’s blocked from the users, they still have the possibility to call them back from a different number.
And that’s the reason why the authorities can’t thoroughly block the phenomenon!
In this case, e best choice is to avoid answering the calls from Tunisia, keeping in mind that sometimes they can be from Moldavia and Kosovo, and most importantly, not to call them back when you find a missed call.
After reading this article, it’s understandable to be suspicious about every app, call WiFi or message and it’s okay, but without being paranoid.
As we have already said, it is sufficient to have a good dose of common sense and to avoid relaying on apps and other channels too much, because they might transmit smartphone virus, dangerous for your privacy and safety.
Therefore, always keep your eyes wide open, but without overdoing it!
