Telegram is a desktop application for Windows that will allow us to talk to all our contacts of this instant messaging service directly from our computer.
And as it is happening in all social networks, Your accounts are targeted for hijacking, especially if they are linked to channels with many subscribers. These types of accounts have been attacked insistently through phishing.
Remember that phishing is a social engineering technique used by criminals to obtain sensitive information like usernames., passwords and credit card details masquerading as reliable and legitimate communication.
In other words,, from a Telegram account you receive a message warning you of a possible error in your account and you are sent a link to a web page, apparently from the same company, in which you are asked to verify your login details. In fact, the page you will access through that link is practically identical to the official one of the company itself..
Once you enter your phone you will be asked for a verification code that you will receive on your mobile phone, and then provide your username and password on the imitation page.
After this last action your data is already exposed and is easily usable by the hacker, in addition to all the contacts you have saved.
To work around this problem you should follow a number of recommendations such as using two-factor authentication, This is an extra security measure that often requires
of a code obtained from an application, or an SMS message, plus a password to access the service.
Verify that the connection is secure and look at the domain of the page in the address bar. In this case, It should be telegram.org, but never a variant of that direction.
Beware of messages from accounts that are not in your contact list and do not access suspicious links.
