Failure to check the object type provides an opportunity for an attacker to create a type confusion error capable of crashing Safari.
Developing a more serious exploit that enables arbitrary code execution would require additional work to create exploit primitives that bypass WebKit defenses like Pointer Authentication Codes (cryptographic signatures for pointers on Arm-compatible devices). Becker nonetheless suggests this malware defense can be overcome by attackers, pointing to recent Project Zero research. This exploit is only the first stage in compromising a user s device, said Becker in an email to
The Register. Attackers would still need to bypass PAC (an exploit mitigation present in newer iPhones and M1 Macs) in order to execute arbitrary code. Also, most user data is not accessible until an attacker escapes the Safari sandbox, which likely involves exploiting additional vulnerabilities.
iOS 14.5 to Make Zero-Click Attacks Significantly Harder
Monday February 22, 2021 8:05 am PST by Hartley Charlton
Apple s impending iOS and iPadOS 14.5 update will make zero-click attacks considerably more difficult by extending PAC security provisions, according to
Apple has made a change to the way in which it secures its code in the latest betas of iOS 14.5 and iPadOS 14.5 to make zero-click attacks much harder. The change, spotted by security researchers, has now been confirmed by Apple and is slated to be included in the final update.
Zero-click attacks allow hackers to break into a target without the need for victim interaction, such as clicking a malicious phishing link. Zero-click attacks are therefore considerably harder for targeted users to detect and are considered to be much more sophisticated.
New language was discovered in iOS 14.5 beta 2
It focuses on zero-click or 0-click hacking.
These are sophisticated attacks.
Apple s about to make it much harder for hackers to take control of unsuspecting iPhones. The company s second iOS 14.5 beta includes language that focuses on a hacking technique known as zero-click, or 0-click, according to Motherboard.
With zero-click attacks, hackers can break into a device without the end-user performing a task. Because no interaction is required, these sophisticated attacks are harder for the targeted user to detect.
These attacks may now become much rarer, according to several security researchers who look for vulnerabilities in iOS.
