WhatsApp for iPhone Vulnerability detected
Recently, WhatsApp version 2.19.20 was released with support for biometric user authentication via Touch ID and Face ID. That is, verification of the fingerprint or face of the user.
one. Select the file on the device you want to share.
2. Specify WhatsApp as the application of interest.
3. Biometric authentication should work here. But it will not be.
4. Now start WhatsApp. Biometric protection will not work here either.
The vulnerability is reproduced if the biometric authentication activation time in WhatsApp settings is set to 1 minute, 15 minutes, or 1 hour.
Therefore, until the developers have released an update with a fix for the vulnerability, we recommend that you select the “Immediately” item (immediately). In this case, the biometric security system works correctly.
