The operation of our 'smartphone' can betray that we are victims of cybercriminals.
The electronic devices, especially mobile phones are one of the main channels through which cybercriminals can access all user information and attack, which is essential to know when they are protected or, on the contrary, They have already been invaded by a malicious program.
One of the main consequences of a mobile phone being pirated is that, once the device is tracked, phishing scams -supplying a legitimate source- can be made against the user, allowing the attacker to carry out operations of gathering information, and using the device as an espionage weapon when accessing the camera, microphone and location .
"Mobile 'malware' is one of the biggest problems in terms of cybersecurity that we face today," says Check Point's technical director for Spain and Portugal, Eusebio Nieva. But there are indications that may indicate that our 'smartphone' has been invaded by an attacker, as the company specializing in cybersecurity explains.
The performance can be an indication of attack; if suddenly the operation of the mobile begins to be slower than usual, it may be that there is a 'malware' that is slowing it down. A simple test to check, as indicated by Check Point, is to see what speed is connected to the network.
Also, the slowness is often accompanied by excessive use of the battery and overheating, which means that it is having a constant use in the background that forces the processor to work for long periods of time at maximum speed.
The appearance of pop-up ads just unlocks the 'smartphone' is a clear announcement of infection, in this case, an 'adware'. They usually appear after downloading and installing some application, which usually utilities or RAM optimizers.
On the other hand, the majority of 'malware' focused on Android uses the telephone number to subscribe the user to 'premium' services, so it will begin to receive service messages (horoscope, etc.) that it does not know about. In addition, you may also be sending these messages to your contacts or posting to your social media accounts without knowing it.
Apps not installed by the user
A final sign of infection is the appearance of applications that the user has not installed and that, many times, are not able to be uninstalled or deleted. This fact also implies a significant increase in the use of data, which can serve as another indicator that something is not right in our 'smartphone'.
