iPhone Zero-Click, Zero-Day Vulnerabilities
What You Need to Know
The digital realm is no stranger to vulnerabilities, but when a zero-click, zero-day is being exploited in the wild, it’s a cause for concern.
The recent discovery of the BLASTPASS exploit chain targeting Apple devices is a stark reminder of the ever-evolving cybersecurity landscape.
The BLASTPASS Exploit Chain: A Brief Overview
What is it? BLASTPASS is an exploit chain highlighted by Citizen Lab, capable of compromising iPhones running iOS 16.6 without any interaction from the victim.
How does it work? The exploit uses PassKit attachments containing malicious images sent via iMessage from an attacker’s account to the victim.
Immediate Action Required: Update Your Apple Devices
Why? Apple has released an update to mitigate this vulnerability. Updating your device is the first line of defense.
How? Navigate to Settings > General > Software Update on your iOS device. Click Download and Install and follow the on-screen instructions. Ensure your device is running iOS 16.6.1 or later after the update.
The Role of Citizen Lab and Apple’s Response
Discovery: Citizen Lab found evidence of a successful exploit while examining a device belonging to an individual from a Washington, DC-based civil society organization.
Collaboration: After the discovery, Citizen Lab promptly informed Apple, leading to a swift investigation and subsequent patch by Apple.
CVEs Issued: Apple has issued two CVEs related to this exploit chain: CVE-2023-41064 and CVE-2023-41061.
Lockdown Mode: An Additional Layer of Protection
What is it? Lockdown Mode is a feature that, when enabled, is believed to block the BLASTPASS attack.
Who should use it? While everyone can benefit from enabling Lockdown Mode, it’s especially recommended for those at an increased risk due to their profession or identity.
The Bigger Picture: Civil Society as a Cybersecurity Early Warning System
Targeted Attacks: This incident underscores that civil society organizations, among many others, are often the victims of sophisticated, targeted cyberattacks.
Collective Cybersecurity: Supporting civil society organizations can enhance our collective cybersecurity, as they often serve as early detectors of new threats.
ATS Security Advisory: Key Takeaways
Affected Software
Apple iMessage on iOS devices, macOS, and other Apple platforms.
Vulnerability Impact
