This rule detects suspicious activity involving macOS LaunchAgents and files within the 'Application Support/System' directory, often associated with persistence or malicious background execution. The detection looks for the creation or modification of specific plist files (e.g., com.apple.finder.agent.plist) or git-related files in Application Support, correlated with process execution of commands like 'sysnotif-repair', 'launchctl' manipulating agents, or git operations involving custom hooks paths.

This rule detects the use of the macOS 'security' utility to unlock the login keychain and modify its access-control list, a technique observed in PamStealer malware to facilitate subsequent unauthorized access to the keychain database.

Detects PamStealer-style browser credential theft on macOS. The detection logic identifies the forced termination of browser helper processes using 'pkill' (which releases SQLite file locks) followed by the execution of a 'KcHelper' binary that uses specific environment markers (e.g., KC_PASS) to bypass keychain authorization prompts and steal stored browser credentials.

Detects sequential Transparency, Consent, & Control (TCC) permission prompts triggered by the 'Terminal' application within a 5-minute window. This behavior is indicative of the AMOS (Atomic macOS) Stealer automating the collection of unauthorized permissions to access sensitive system locations such as Finder, Desktop, Documents, and Notes.
Detects unauthorized modifications to the 'endo_voyager_dictation_endpoint' preference key within the 'com.meta.muse.plist' file on macOS. This key is an undocumented configuration setting that, if modified, allows an attacker to redirect dictation traffic to a malicious, attacker-controlled endpoint.

Detects the use of the 'security' utility on macOS to modify the partition ID list of keychain items. This action is commonly performed to grant silent, persistent access to sensitive stored credentials or cookies, such as those used by web browsers, by bypassing the system's interactive keychain access prompt.
Detects a suspicious sequence of anti-analysis behaviors on macOS, where a process first checks for the presence of a hypervisor via sysctl (kern.hv_vmm_present) and subsequently invokes ptrace with PT_DENY_ATTACH, a technique often used to prevent debuggers from attaching to a process.
Detects a suspicious sequence of events where a user or process removes the 'com.apple.quarantine' extended attribute from a file bundle using 'xattr -cr', immediately followed by ad-hoc code signing the same file using 'codesign -s -'. This pattern is commonly used to bypass macOS Gatekeeper security controls by stripping quarantine flags and re-signing the application to allow execution of untrusted or modified code.
Detects the initiation of the OAuth 2.0 Device Authorization Grant flow via command-line arguments within standard web browsers. This flow is frequently exploited in phishing campaigns to obtain unauthorized access tokens by tricking users into entering a device code on a malicious or attacker-controlled authorization page.
Detects the removal of the com.apple.quarantine extended attribute from a file followed by the execution of the macOS 'security' utility to dump or retrieve passwords from the Keychain within a 5-minute window. This sequence is indicative of an adversary attempting to bypass Gatekeeper-related restrictions on a potentially malicious tool, followed by unauthorized access to sensitive credentials stored in the Keychain.
