You really need to talk to your wife and come clean with it. You will feel relieved. Yes, scolding and nagging will follow. But she have the right to know as well. As those idiots will keep harass her. You need to be fair to her as well. And best to warn her to change her WhatsApp profile picture in case those idiots save it and use it to threaten you even more.
