Do we know the true dangers of a network using Wi-Fi public? It is tempting to find a Public WiFi Networks open but before logging in the first we meet, keep in mind that our data and passwords can be compromised in the interests of any hacker.Everyone occasionally has used the availability of a network Wi-Fi public in order to speed up a search, or simply not to consume device data. Even for those who do not have a data plan on your smartphone, tablet or PC, has become a very common habit. Despite the convenience of a Wi-Fi, such as offering bars, hotels, airports or shopping malls, we are exposing our data, passwords or any information left in the hands of hackers .


The hotspots and public access points to the Internet are the networks that are present in bars, restaurants, public buildings and squares. Some ask for password, others not, but nearly all of them are susceptible to hackers enter and take hold of what you do while staying connected, without the user noticing.

A study on the Security Risk on Consumers conducted by B2B International for Kaspersky Lab a 36% of Spanish users takes no protection when connected to a Wi-Fi network . In addition, 15% shop online or connected to your bank account through these ‘hotspots’ and only 13% check the encryption level.

How hackers act

An attacker to intercept data as passwords to social networks or financial information without any encryption in communications between users and the access point, is a task as simple and they can make huge profits in the black market or steal directly from the bank accounts of users.

Kaspersky Lab data indicate that the operating system of Google is still the main target of hackers. Daniel Creus analyst Kasperky Lab, explains it as follows: “What they do, for example, is to choose an access point as a shopping mall The attacker can create a network with a name that already exists but with more intensity. signal, which will call more attention from internet users. ”

How to tell if you have ‘hacked’

To find out if your device is infected, Daniel Creus advised ” check if our device performs some anomalous behavior as the growth of bandwidth consumption, unwanted ads, high bills without reason or unsolicited applications. ” The danger is present throughout the year but hackers exploit periods when there are large numbers of people in public places, such as Christmas in malls. Attackers are interested in places where they can get beneficial data, as happened about a year ago in the European Parliament . “They did not seek money, but information of a different caliber,” said the same source.

What steps to take to protect

Fortunately, there are steps we can take to protect our devices. To avoid falling victim to such attacks, Kaspersky Lab experts recommend using secure connections to these access points . The Euro pol, police agency of European Union , not advised to stop using the ‘hotspots’ public Wi-Fi, just take precautions like not using them for banking transactions or for activities that have to give personal information, using some sort of data encryption, connect only to access points that we know who is the owner and turn off automatic reconnection to networks WiFi on mobile.

When you enter a public Wi-Fi, Kaspersky advised to use a free VPN (virtual private network). The problem is that many managers of public services this block internet access to ensure that your network will not be used for malicious purposes.
