WhatsApp is one of the most used internet instant messaging platforms today, it is even said that it exceeds 2 million active users, but a very important point that must be taken into consideration is cybersecurity, that is, all the sensitive data that it has. the application about our life, information that can be used by third parties, not authorized for their purposes.

Although the company is indeed protected for this, it is a reality that a lot of personal data is shared within the platform, as demonstrated by Chema Alonso, the CDO of Telefónica and hacker. According to what the expert said, sometimes the information we send and receive on WhatsApp includes sensitive content such as bank cards, and passwords, among others.

Tips to take care of your information on WhatsApp

According to Chema, everything begins with the login, we always have to enter a username and password on the platforms, and even in some places a card is required to access, but one of the vulnerabilities he has detected is that anyone can know If an email has an account on a platform, it is enough to place the email in the user and write a password, the system will throw an incorrect password, with this we know that this email is linked to the platform, only that we do not have access to it.

Also, a vulnerability that the platform has is the issue of location, since any user can know it by sending a link that collects that information and they can access it, so we must be careful of all the links that we see in contact states or that are sent to us in groups or conversations since we could “accidentally” give access to our location.

Another security issue is the name with which we register in the application, this name is public and anyone who has our number or sees us in the groups will know our name, so we must be aware of the use of it.

Chema has done experiments, creating programs that allow detecting when someone is online, with this they can calculate what time you sleep and what time you get up, also on the subject of writing, if you write the first letter with a capital letter it can mean that you are connected from your smartphone and not from a computer.

Finally, one of the main tips to take care of our information on WhatsApp is, do not to open unknown links and verify beforehand that they are safe websites and not copies of them, we can hide our connection time and the name that we use on the platform. choose it correctly so that they do not violate our privacy or security.

Also, on some devices like Apple’s, it will appear at the top if someone is using our location and with this, we can detect if someone else knows what we do.
