InterceptX - iPad just got hacked

Hi folks,

my iPad running the latest ipados and interceptX was hacked using a known hack in Facebook messenger.

Thankfully my contact list is not that great and I was able to unsound the bad message.

The iPAD is also guarded by XG and at the time the initial attack it was not using decrypted and scan which it was when the messages were sent but there is an exception in web policy for facebook.

Why wasn't the known hack stooped by interceptX.
