Google researchers have uncovered a malicious attack against iPhone users, which could be one of the largest ever. They uncovered a series of hacked websites that have reportedly been delivering attacks designed to hack iPhone users. 

Google says that these websites have delivered their malware indiscriminately. The most interesting fact being that scale were these websites were visited thousands of times every week. The search giant has also observed that these attacks were operational for years. Some of these attacks used zero day exploits and took advantage of vulnerability that Apple was not aware of at the time. 

In the past, zero day exploits have been found to be the most effective way to hack into devices. Researchers at Google have been at the forefront of finding zero day exploits affecting popular operating systems and software.

“There was no target discrimination; simply visiting the hacked site was enough for the exploit server to attack your device, and install a monitoring implant,” said Ian Beer, member of Project Zero.
