These kinds of messages have a typical mechanic, the place a message containing unusual characters. Although WhatsApp can acknowledge a few of these characters, there are mixtures that make the software unable to learn them, and consequently a string of infinite hangs.
Infinite hangs: a fault for three years in WhatsApp
These infinite crashes imply that, as soon as the first WhatsApp crash is generated when a message is acquired, it’s performed once more when the software is opened and it tries to reload the message with the modified characters.
The official WhatsApp software doesn’t have any mechanism to guard itself towards receiving these characters. Interestingly, there are modified WhatsApp functions, comparable to WhatsApp Plus, that combine the so-called “Crashcode safety”, by means of which they combine a bigger Unicode database. Thanks to this, they’ll acknowledge extra characters and it’s tougher to make these hold. However, utilizing these modified apps can get your account banned, and encryption in messages isn’t assured.

To keep away from crashes, it is suggested, earlier than opening the message, block and delete chat from WhatsApp Web, the place the vulnerability doesn’t work. If as a substitute now we have already opened the malicious message or the contact card, and the software is crashing, we can have no alternative however to reinstall WhatsApp and lose all the messages that now we have despatched and acquired since the final backup.
The downside has been current in WhatsApp for 3 years now, and the platform does nothing to repair it. The solely possibility now we have to keep away from that is to dam the undeniable fact that strangers converse to us, though we might lose contact with many individuals whose quantity we don’t have in our agenda, and that doesn’t exempt us from having a contact that we have already got in the mobile cellphone can ship us malicious code to bother us.
