Life explained how attackers can access WhatsApp messages and how
Due to the fact that now WhatsApp can be usedon several devices at the same time, the scammers have a new "loophole". After scanning the QR code on your smartphone, you can access the owner's account. To avoid this, "Life" advises to set a password to launch the application and not give your smartphone to strangers.
Check if someone else has already receivedaccount access, simple. You need to go through the "Settings" to "Associated devices". All gadgets on which the account is used will be listed there. You can remove unnecessary ones from them.
Another WhatsApp vulnerability is a messenger utility for Android. In this case, you can understand that something is wrong by the strong heating of the device and increased traffic for the messenger.
Already deleted messages can be read in WhatsApp.Although the developers assured that nothing is stored on the server after deletion. This vulnerability may have already been fixed. In any case, you can understand that deleted messages are being restored by their appearance in the correspondence.
Various extensions for an Android application can either slow down the messenger or transfer data to third parties. Therefore, it is better not to download anything other than WhatsApp itself to your smartphone.
Also in the application there is a function of sending a chat by mail. Moreover, you can do this with one click - and a letter will come with all the messages.
There are two strong indications thatWhatsApp is hacked. The first is network latency while downloading messages. The second is to send one-time codes (then you need to click in the application "Exit from all devices" and go back to the messenger).
