macos-collector v1.7.0 Released: The Ultimate Automated DFIR Tool for Apple Endpoints

Security teams responding to compromised Apple endpoints have a powerful new utility at their disposal with the release of macos-collector v1.7.0. This comprehensive shell script is designed to automate the collection and analysis of macOS forensic artifacts, streamlining Digital Forensics and Incident Response (DFIR) workflows. By acting as a centralized orchestrator, the tool eliminates the need for investigators to manually run disparate command-line utilities during a critical security incident.

At its core, macos-collector heavily leverages Aftermath, an open-source incident response framework developed by Jamf Threat Labs. However, the script goes significantly further by bundling essential external tools by default. This ensures that responders have immediate access to a full suite of diagnostic capabilities without needing to download additional dependencies on a potentially compromised machine.

The v1.7.0 release is built to extract a wide array of critical system data necessary for identifying malicious activity. The script automates the extraction of Apple Unified Logs (AUL), Background Task Management (BTM) dumps, DS_Store files, and File System Events (FSEvents). Furthermore, it captures Sysdiagnose logs, Spotlight database files (including live searches), Recent Items, Notification Center databases, and Biome data.

To achieve this deep level of system introspection, macos-collector relies on specific, pre-packaged versions of industry-standard security tools. The current build includes 7-Zip v26.00 for secure archiving, Aftermath v2.3.0 for core artifact collection, KnockKnock v4.0.3 for live system persistence enumeration, and TrueTree v0.8 for process tree snapshot collection. The tool also checks system information, such as verifying if the native XProtect anti-malware signatures are up to date.

Because macos-collector interacts with deeply embedded system files, it requires root privileges and specific system permissions to function correctly. Furthermore, to preserve the integrity of the compromised endpoint, investigators must follow strict operational security practices.

• Minimize Disk Writes: The script writes its output directly to the current working directory. It is highly recommended to execute the tool from a remote location or an external device, such as a USB flash drive, to prevent overwriting volatile forensic evidence on the target disk.
• Grant Full Disk Access: Aftermath requires Full Disk Access (FDA) to read protected directories. Navigate to System Settings, select Privacy & Security, and open Full Disk Access. Click the + button, authenticate, and add your Terminal application. You must restart the Terminal for changes to take effect.
• Archive Security: All collected data is securely archived. The default password for the main archive is IncidentResponse, while the password for quarantined files is infected.

Once the environment is prepared, investigators can use the following commands to initiate specific collection routines:

To collect forensic artifacts using Aftermath:

sudo bash macos-collector.sh --collect

To analyze a previously collected Aftermath archive file (ideally performed on a clean, isolated macOS endpoint):

sudo bash macos-collector.sh --analyze

To specifically collect FSEvents data from the compromised endpoint:

sudo bash macos-collector.sh --fsevents

To perform a complete triage and collect all supported macOS forensic artifacts:

sudo bash macos-collector.sh --triage

The release of macos-collector v1.7.0 highlights a critical evolution in Apple enterprise security. Historically, macOS was perceived as a lower-priority target for threat actors, allowing security teams to rely on slower, manual forensic methodologies. However, with the recent surge in macOS-specific info-stealers and sophisticated persistence mechanisms, rapid triage is no longer optional - it is a baseline requirement.

By wrapping complex tools like KnockKnock and TrueTree into a single, easily deployable shell script, macos-collector drastically reduces the time-to-insight during an active breach. The explicit requirement to run the tool via an external drive also reinforces proper forensic hygiene, ensuring that junior analysts do not accidentally trample over crucial file system events while attempting to gather data. As macOS continues to expand its footprint in corporate environments, automated, all-in-one collection scripts like this will become the standard first-response mechanism for security operations centers.
