Detects HTTP POST requests to '/api/credentials' over a non-standard port (8133) typical of AMOS (Atomic macOS Stealer) command and control traffic. The rule specifically looks for established network connections originating from the local network and targeting external hosts, flagging multiple occurrences within a 30-second window.

This rule detects outgoing HTTP POST requests to the 'velvet-otter-glagceis.life' domain path '/collect'. The request body contains indicators of victim fingerprinting, specifically looking for 'visitorId' and 'events' fields, characteristic of the Macfinger/ClickFix campaign used for gathering visitor telemetry for malicious purposes.

Detects outbound TLS traffic where the Server Name Indication (SNI) matches known command-and-control (C2) domains associated with the Sauron Loader malware. This indicates a compromised host attempting to communicate with malicious infrastructure.

Detects activity associated with the Sauron Loader malware, specifically monitoring for the execution of rnpkeys.exe or loading of tdwp.dll, followed by a high volume of HTTPS POST requests to the same destination host, which is characteristic of chunked screenshot exfiltration.

Detects execution of rnpkeys.exe from the C:\ProgramData\keyroll\ directory, which is indicative of Sauron Loader side-loading activity, followed by an outbound network connection on port 443 within a 5-minute window. This behavior is consistent with the initial bot registration beaconing phase of the malware.

Detects HTTP POST requests to '/api/credentials' which is indicative of the AMOS (Atomic macOS) Stealer malware exfiltrating stolen credentials. The rule uses a threshold to identify multiple exfiltration attempts from the same source within a short time window.

Detects instances where critical system processes (such as svchost.exe, lsass.exe, or w3wp.exe) spawn known command-line interpreters or script execution utilities (e.g., cmd.exe, powershell.exe, certutil.exe) which then initiate outbound network connections to common ports (445, 3389, 135, 5985, 5986, 1433, 80, 443) that are external to the local network. This behavior is often associated with lateral movement, command and control (C2) communication, or reconnaissance.

This rule detects network and email activity associated with a list of known suspicious or 'ghost' domains. It monitors email sender and recipient addresses, email URL links, and DNS query logs for matches against the predefined domain list, identifying potential spearphishing or command-and-control communication.

This rule detects a correlation between host-level reconnaissance activity using WMI (via PowerShell or WMIC) to query system information, followed by network exfiltration to a known C2 IP address over a specific URI within a 10-minute window.

This rule monitors endpoint telemetry (File, Process, and Network events) to identify activity associated with a pre-defined set of known malicious file hashes, IP addresses, and domains. It correlates these indicators to detect potential malware execution, persistence, or command-and-control communication on monitored devices.

This rule detects known command-and-control (C2) domains associated with the Sauron Loader malware family, specifically by inspecting TLS Server Name Indication (SNI) fields. It also monitors for patterns of repeated connections to domains prefixed with 'api.' over established TLS sessions, which may indicate beaconing behavior characteristic of C2 activity.

This rule monitors for known malicious file hashes, IP addresses, C2 domains, and specific URL markers associated with identified threat activity. It consolidates multiple detection vectors including file activity, process execution, network connections, and DNS queries to identify compromised devices communicating with attacker-controlled infrastructure.
