Apple devices are vulnerable to a text bomb attack where simply looking at messages or posts containing characters in the Sindhi language can crash devices. The bug affects iPhone, iPad, Macs and Apple Watches. Android users can meanwhile log this one as a win in the mobile device wars: Google s OS is unaffected. The issue was first reported on Reddit on Thursday and given the moniker CapturetheFlag because the offending characters are often paired with the Italian flag (the flag though is not necessary to trigger a crash)
