MADRID, 11 Sep. (Portaltic/EP) –
Due to causes such as telecommuting, the ‘smartphone’ increasingly contains more sensitive information, such as documents, bank details, passwords, personal and corporate information, and therefore, it has become a common attack target for cybercrime.
It is not always easy to tell when a device has been infected by ‘malware’, but there are a number of signs that can set off alarms and make you think you’ve been infected, as the cybersecurity company Check Point has explained.
The first of the ‘malware’ symptoms has to do with how it works: if the device slows down, if the ‘apps’ or programs are closed for no apparent reason or tools such as the flashlight stop working.
These changes are a red flag, especially if it happens after having installed a program or having clicked on a link that may have downloaded a malicious program.
That the battery discharges very quickly it is another factor that can indicate a ‘malware’ infection. If you don’t spend a lot of time using it and, conspicuously and in a short space of time, the charge goes from being full to less than half, you have to check the device.
To do this, Check Point recommends accessing the settings section and, in the section dedicated to the battery, check which applications consume the most to detect what the origin may be.
The same way, malware can be accompanied by an increase in data consumption. If the data bill suddenly increases, it may be due to downloading applications without the user proactively doing so.
These malicious ‘apps’ consume large amounts of data by exchanging information with a cybercriminal’s command control center. To solve it, it is best to go to the list of ‘apps’ and uninstall all those that are not familiar or known. You can also check the data consumption of each ‘app’ in the settings.
Another possible indicator may be see advertising in the notification bar. Known as ‘mobile adware’, this type of malicious program aims to display unwanted advertisements on the phone screen.
When it runs, the ‘malware’ hides its icon to prevent it from being removed, at the same time that it begins to distribute ads on the screen, regardless of whether the user is inside the application or not.
Check Point also recommends be attentive if strange numbers appear in the call and SMS list, generally foreigners. In addition, it may also be the case that the phone autonomously sends SMS messages to unusual numbers or even to all contacts.
This fact can not only generate an economic cost for the user, but also serves the cybercriminal to spread ‘malware’ including malicious links in these messages. If a month there is an increase in expenses for no apparent reason due to services that have not been used, it is time to analyze the status of the device.
