If Telegram or WhatsApp are sending service notifications, this may indicate that your messenger account has been hacked. Viktor Ievlev, senior specialist in the information security department of the Garda group of companies, told socialbites.ca.
According to him, in this case, you first need to check active messaging sessions, that is, all situations where you are logged into your account on other devices. These can be computers, relatives’ smartphones, work devices, old appliances. You must close all active sessions.
In Telegram, you can do this by going to “Settings”, opening “Devices” and clicking the “End other sessions” button. In WhatsApp, you also need to open “Settings” and go to “Paired devices”. Next, you need to select each unnecessary device and click “Exit”.
Additionally, in order to protect correspondence and other personal data, Ievlev advised users not to follow links from senders they do not know. You should also be careful when you suddenly receive connections from people you know. In the second case, it is better to clarify the situation by contacting the sender through another communication channel.
“In most cases, fraudsters’ actions are aimed at stealing credentials. Attackers send messages asking you to vote in a contest, log in to a fake website, scan a QR code, or something similar. Such messages come from both familiar numbers (if they have been hacked) and unfamiliar numbers. “It is necessary to be vigilant in all situations,” said the expert.
If you open a malicious link, two-factor authentication will help protect your account. It can be activated not only in Telegram and WhatsApp, but also in Viber and VK Messenger.
Previously in Russia was recorded a new type of super-volume DDoS attack.
