Apple’s Response

Apple has addressed the vulnerability by introducing improved checks in the following updates:
  • Safari 18.1.1
  • iOS 17.7.2 and iPadOS 17.7.2
  • macOS Sequoia 15.1.1
  • iOS 18.1.1 and iPadOS 18.1.1
  • visionOS 2.1.1

Advisory from CISA

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added CVE-2024-44308 to its Known Exploited Vulnerabilities Catalog. CISA strongly urges organizations and individuals to update their devices by December 12, 2024, to mitigate risks.

Growing Threats to macOS

This vulnerability underscores the increasing prevalence of attacks on macOS systems. Security experts note a significant rise in macOS malware targeting cryptocurrency businesses and other high-value sectors. The active exploitation of Intel-based Mac systems further highlights the need for robust security measures.

Recommendations

Users and organizations are strongly advised to:
  • Update immediately to the latest versions of Safari, iOS, iPadOS, macOS, and visionOS to mitigate risks.
  • Implement security best practices, such as enabling auto-updates and avoiding interactions with suspicious web content.
  • Monitor device logs for unusual activity, especially if operating in high-risk environments.
By promptly applying patches, users can protect against unauthorized access, data theft, and system compromise. The rapid response to CVE-2024-44308 demonstrates the critical importance of timely updates in defending against sophisticated exploits.
