A deep dive into iOS Exploit chains found in the wild (googleprojectzero.blogspot.com)

Article summary

A recent blog post provides a deep dive into iOS exploit chains found in the wild, including a teardown of the implant used and analysis of the browser exploits used as initial entry points. The exploit chains were used to target iOS users, allowing attackers to steal private data such as iMessages, photos, and GPS location in real-time. The implant was designed to be non-persistent, requiring a reboot to remove it, but it could still upload keychain data and maintain access to user accounts. The post highlights the sophistication and complexity of the exploit chains, which were likely developed by a professional team.

Main themes

• iOS security
• exploit chains
• privacy concerns
• nation-state hacking
• mobile security

What commenters say

• The iOS walled garden model makes it difficult for security researchers to detect and investigate infections like this, which could be a significant problem.
• The fact that the exploit chains were used to target specific groups, such as dissidents, raises concerns about the use of zero-days for surveillance and intelligence gathering.
• Enabling 2FA and using a laptop for financial transactions can provide an additional layer of security, but some argue that this may not be sufficient to protect against sophisticated attacks.
• Others argue that using a laptop, especially one running Linux, may actually be more secure than using an iPhone for certain activities, due to the lower number of zero-days and better security features.
• The use of mobile EDR solutions may not be effective in preventing attacks like this, especially when the attacker has a kernel write primitive.
• Some commenters suggest that the exploit chains may have been developed by a nation-state actor, given the level of sophistication and resources required to create them.
• The fact that the implant was able to steal sensitive data without being detected for a long time highlights the need for better security measures and more transparency from Apple about its security practices.
