WhatsApp’s “Delete for Everyone” feature, meant to allow people to delete files they accidentally sent, works differently on iPhones than it does on Android phones, a researcher has warned. This discrepancy could place senders’ privacy at risk by leaving some media files undeleted on recipients’ iPhones.
WhatsApp has a vast install base of 1.5 billion users in over 180 countries. Most WhatsApp customers use the service daily, including for group chats with friends, family members or co-workers. Such a popular service is subject to scrutiny from privacy activists and cybersecurity researchers.
