Mac-ing Sense of the 3CX Supply Chain Attack: Analysis of the macOS Payloads

Expert analysis of the macOS payload from the 3CX supply chain attack, uncovering the malware's behavior, encryption methods and tactics used.

Key takeaways

Malware authors often target software supply chains to gain access to victims’ systems.
The Mac malware payload encrypts the config.json file, making it difficult to analyze.
Most Mac malware is not publicly available, but supply chain attacks can provide a way to access and analyze malware.
The use of open-source software can help with malware analysis and detection.
Publicly available malware samples can be used to study and understand malware behavior.
When analyzing malware, it is essential to decrypt and analyze the strings to understand the malware’s purpose and functionality.
Supply chain attacks can be challenging to detect and respond to, as they often involve modifying or tampering with software development processes.
Apple’s notarization process can help detect malicious software, but it is not foolproof.
macOS has its own antivirus software XProtect, which can detect malware, but it is not foolproof.
Firewalls for Mac OS can help detect and block malicious traffic.
Malware authors often use common programming languages like Objective-C and Swift to develop malware.
Administrators should have a comprehensive antivirus solution and keep it up to date.
When analyzing malware, it is essential to understand the context and the environment in which it was executed.
The use of open-source software can help with malware detection and analysis.
Supply chain attacks can be devastating, and it is essential to have a disaster recovery plan in place.
