Can the iPhone5 be hacked remotely by a hacker?
I work for a technology company and one of our employees shared an incident about her iPhone5 being hacked remotely. The hacker gained access to her device overnight while her phone was unlocked. The hacker watched her baby monitor video feed from the baby monitoring app (including taking pictures and video from the device), posted about the baby to her FB account, browsed on Safari, including some searches of French books on amazon and Scott Trading sites. When I spoke with the mobile device team, they were not familiar with any iOS security gaps that would allow a hacker to remotely gain control of an iPhone, however, the activities on her device suggest that this is possible.
I found some articles from 2009 regarding a SMS virus that allowed hackers to gain remote access to a device, however, our mobile device team is certain that this gap would be closed by now.
Is anyone familiar with an existing security gap on the iPhone5? What would you recommend would be the next action for her? She is intending to delete her icloud account, change all her passwords and wipe her device.
