The vulnerabilities was shared with WhatsApp on August 21th, and a patch was rolled out on August 27th, which blocked the feature. The prompt action of WhatsApp was applauded by Checkpoint, whose Security Research Group Manager Oded Vanunu remarked that “WhatsApp responded quickly and responsibly.” The security firm also hope for the same professional course of action from other vendors.
