The recent worldwide cyber attack that has plagued a large number of users in the last few days has called for so-called ransomware. It is a process by which the attacker infects the information stored on the affected device and encrypts the preventing the owner access and asking for economic compensation to be able to recover. Despite this type of malware always being connected to the desktop, the fact is that the Android platform is also susceptible to be affected by these more and more common attacks.
In a mobile device, the main way we can get infected is by downloading a fraudulent application without our consent or being cheated by some kind of identity theft system, and the way of arriving at these applications can be through instant messaging services like Whatsapp. That’s why it’s imperative to have tools that can analyze the documents received before installing them and monitor the apps we use on our smartphone. Here are some tips to protect our malicious software devices. <
Analyze your apps with Virustotal
The Virustotal service, owned by Google, offers a service whereby we can scan any application for more than 50 antivirus programs and receive a detailed information with the results. In addition to its web version, it has a totally free application that, once installed in our smartphone, will analyze all the applications that we have installed and warn us of those that it considers suspicious. Also, we can send files and even analyze URLs. Still, it is worth mentioning that this application does not offer protection in real time, being its use a complement to the common sense itself and other applications that provide some system of shielding.

Download from trusted sources
Precisely, We use Virustotal to analyze all the files that we store, performing a filter of the same if it is detected as malicious by some of the associated antivirus. Yet, the human component in the process helps minimize possible malware entry into the platform. That’s why Google Playis ranked as one of the best alternatives to the Play Store in security level. Still, thanks to the official application we can update our applications automatically as if it were Google’s service.
Attention to the permissions used by each app
Another of the fields to take into account when testing the reliability of an app is to check the permissions required for its correct operation. It does not make much sense, for example, that a text editor has access to our contact list, or that an alleged puzzle game makes use of the camera. While newer versions of the Android operating system notify us when “sensitive” permission is required, users with outdated terminals will need an external tool to review this. MyPermissions Privacy Cleaner allows you to review the installed apps and check if they use permissions that a priori should not, thus detecting if we are using a fraudulent version of the software in question. It also allows you to control the open login sessions that we have in social networks to which we access among other protection features.
Phishing through instant messaging
It is known that infection through malicious applications is the main cause of the problems. And where do these apps come from? Mostly links received through WhatsApp and other chat services where viralization and immediacy play in favor of malware. There is much default through WhatsApp whose primary weapon is to resort to so-called phishing to deceive careless users. That is, offer sites that pose as official services and that offer us wonderful promotions, whether skins to customize WhatsApp itself or discounts on services like Netflix. Also, these fraudulent sites already make sure that the infected person shares the malicious link with their contacts, and in most cases the contact that sent us the said link does not even know that it did.
Use Common Sense
No marketplace, including Google Play itself, saves itself from being invaded by fraudulent applications, and anti-virus as such is useless on the Android platform. In the end, the main barrier to infection is ourselves and our ability to discern the reliability of the pages we visit and applications we download. You have to be cautious, contrast with reliable sources of information and, if in doubt, never click on a link in the “Accept” button.
