Detects the execution of the 'csrutil status' command, which is used to check the status of System Integrity Protection (SIP) on macOS. This query specifically looks for this command being executed by 'osascript' or 'Script Editor', which are common methods used to automate or hide the command execution.
Detects instances where 'Script Editor' or processes containing 'Maccy' in their command line access specific timezone files in /usr/share/zoneinfo. This behavior is indicative of potential environment checks for virtualization or sandbox detection, as attackers may attempt to identify or spoof the system's timezone to evade security analysis.
Detects process execution attempts where the binary is located in the /private/tmp directory, specifically targeting a file named 'System Settings'. Executing binaries from temporary directories is a common technique used by attackers to stage and run malicious payloads while attempting to blend in with legitimate-looking filenames.
This rule detects the presence of known LokiBot packed binaries by matching the SHA256 hashes of staged memory section bins that were recovered during unpacking analysis. This indicates a high-confidence match for known malicious samples associated with the LokiBot information stealer.
Detects the use of WMI (via WmiPrvSE.exe or wmic.exe) to enumerate or terminate PowerShell processes. This behavior is indicative of the Amadey/StealC delivery chain, where a JScript dropper uses WMI to clean up script execution artifacts after a specified timeout, aiding in defense evasion.
Detects the presence of the Montana Empire phishing kit within ZIP archives. The rule identifies specific PHP backend components (mentalite.php, panel_track.php, verify_api.php) often used for credential harvesting, along with unique branding strings and artifacts suggesting AI-assisted development of the phishing kit.
Detects the execution of known command-line utilities, script interpreters, or installers spawned by web browsers from high-risk directories such as the User Downloads, Temp, or TMP folders. This behavior is indicative of a user downloading and executing malicious files or scripts directly from a web browser.
Detects outbound HTTP requests to a known phishing infrastructure panel associated with the Montana Empire malware campaign, specifically targeting the /mentalite.php endpoint on pttvm.com.
This rule monitors outbound HTTP responses to detect the presence of the Montana Empire phishing panel by analyzing specific branding artifacts, such as strings like 'ENTER THE EMPIRE', '256-bit Encrypted', and 'Brute-force Protected' located within the HTTP response body associated with the URI '/mentalite.php'.
Detects DNS queries for domains that are visually or phonetically similar to popular software package registry domains (such as PyPI or npm). These are often used in typosquatting campaigns to trick users or automated systems into downloading malicious packages.
