Hackers can access your iPhone just by sending a text message

You’ll likely begin to push a malicious connection into a message, to download a fraudulent app or in some other manner, by accident if you believe of how hackers can break into your smartphone that doesn’t necessarily happen— even on the iPhone, where it can be enough to just receive an iMessage to pick up.

Google’s Project Zero researchers Natalie Silvanovich presented several so-called “interaction-less” bugs at the Black Hat safety meeting in Las Vegas on Wednesday in Apple’s iOS iMessage client that could also be used for controlling the phone. And although six of these have been patched by Apple, several still have to be patched.

In the latest drastic WhatsApp vulnerabilities which permitted nation-state spies to compromise a phone by calling — even if the recipient did not answer the call —, Silvanovich who worked on investigations with Samuel Groß, a project fellow zero member, became interested in interaction-less bugs.

However, she went empty when she looked at comparable problems in SMS, MMS, and visual voicemail. Silvanovich had presumed that iMessage was a more screened and locked down target, however, she rapidly discovered multiples exploitable bugs when she began reverse engineering and looked for defects.

This can be due to iMessage being such a complicated platform with a variety of communication alternatives and characteristics. It includes Animojis, pictures, and videos, and integrates with other apps, from Apple Pay and iTunes to Fandango and Airbnb. All such extensions and linkages improve the probability of errors and weaknesses.

A major logical problem that a hacker could have been able to readily extract information from user posts was one of Silvanovich’s most interesting interaction-free bugs. 

An intruder could send a particular text message to a destination, and the iMessage server would return certain user data such as their SMS messages or pictures. The victim wouldn’t even need to open his iMessage app to operate. 

iOS has protections in place that would generally block such attack, although iOS defenses understand the system as lawful and designed because of its fundamental logic.

Further bugs that were discovered in Silvanovich could lead to malicious code placed from the incoming text on a victim’s computer.

Interaction-less iOS bugs are extremely appreciated by exploit suppliers and national hackers as they make it simple to compromise the device of the target without any buy-in from the victim. Silvanovich has found — and there are still more — six vulnerabilities that could cost the exploit industry millions or perhaps even millions of bucks.
