Detects the execution of base64-encoded shell commands on macOS, a pattern commonly associated with the 'ClickFix' social engineering campaign where users are tricked into copying and pasting malicious payloads into their Terminal.
Detects potential Certificate Authority (CA) key theft by correlating command-line execution of certutil (with export flags) on a CA server with subsequent suspicious certificate issuance events. Suspicious issuance includes unauthorized certificate requests (missing event 4886), requests for high-privilege subjects (e.g., Domain Admins), or requests with unusually long validity periods.
This rule monitors for two distinct suspicious patterns: first, the interaction between Claude Desktop and the CEF (Chromium Embedded Framework) library, which may indicate unauthorized plugin or extension loading; second, the execution of non-standard binaries initiated by various JetBrains IDE processes located outside of standard program directories, which could indicate process hollowing or unauthorized tool execution.
Detects the execution of RatHat, a Go-based Android native daemon masquerading as 'liblocal-service.so'. The rule identifies the malware's use of ADB-derived shell commands to bypass Android Doze mode, prioritize background execution, and tamper with installed applications via pm (package manager) commands.
IOC hunt for the HEAVYGRAM/CRUDEEXCLUDE campaign: matches known SHA256 file hashes (first-stage malware, implant, RAR/ZIP artefacts) via DeviceFileEvents and DeviceProcessEvents, plus known-malicious domains/staging infrastructure by parsed hostname across network connections, process command lines, and file origin URLs.
Detects unauthorized child processes spawned by ScreenConnect client binaries. The rule specifically looks for files created or modified within 60 seconds prior to execution, which is indicative of attackers leveraging an authentication bypass vulnerability (CVE-2026-84869) to transfer and execute malicious payloads via an active remote access session without requiring additional user interaction or authentication.
Detects the execution of the Rubeus toolset with command-line arguments indicative of Kerberos ticket abuse, including Kerberoasting, AS-REP Roasting, and Pass-the-Ticket (PTT) techniques. These methods are commonly used by adversaries for credential harvesting and facilitating lateral movement within an Active Directory environment.
This rule monitors for the execution or presence of files matching a specific set of known malicious MD5 hashes within the environment. It leverages DeviceFileEvents and DeviceProcessEvents logs to identify if these specific files are being accessed or executed on managed endpoints.
This rule monitors for the execution or presence of files matching a specific set of known malicious MD5 hashes within the environment. It leverages DeviceFileEvents and DeviceProcessEvents logs to identify if these specific files are being accessed or executed on managed endpoints.
Detects DragonForce ransomware attempting to identify accessible SMB network shares by executing 'net view' commands. This activity is a precursor to encrypting files on reachable administrative shares (e.g., C$) while excluding system-specific shares like ADMIN$.
Detects access to sensitive cryptocurrency wallet files (wallet.dat, seed phrases, keys) or the execution of Python processes from sensitive or commonly exploited directories (AppData, tmp, Public folders) associated with known malicious naming conventions (sys_service).
This rule detects the execution of processes that contain the command line argument 'Found sid:', which is commonly associated with security identifier (SID) enumeration or lookup tools/scripts, such as those used by security researchers or attackers during reconnaissance.
Detects the use of native Windows tools like vssadmin and wmic to delete Volume Shadow Copies. This activity is a common indicator of ransomware or other destructive attacks attempting to inhibit system recovery.
This rule monitors for the execution or presence of files matching a specific set of known malicious MD5 hashes within the environment. It leverages DeviceFileEvents and DeviceProcessEvents logs to identify if these specific files are being accessed or executed on managed endpoints.
Detects unauthorized shell-level ADB commands characteristic of the RatHat Go Agent, including modifying doze/standby settings, granting security permissions (WRITE_SECURE_SETTINGS), and disabling or uninstalling system packages via the 'pm' command after self-pairing.
Detects a malicious persistence pattern where an out-of-lifecycle daemon (e.g., liblocal-service.so) leverages ADB shell access to silently reinstall an APK and re-grant Accessibility permissions shortly after the application is removed by a user or the system.
This rule detects unauthorized screen surveillance on Android devices by correlating the execution of the minicap binary with subsequent network activity indicative of screen data exfiltration to a command-and-control (C2) server. It specifically looks for connections to known exfiltration paths associated with screen monitoring or video uploads within 30 minutes of minicap process activity, effectively identifying surveillance that bypasses Android's MediaProjection consent mechanism.
This rule detects unauthorized screen surveillance on Android devices by correlating the execution of the minicap binary with subsequent network activity indicative of screen data exfiltration to a command-and-control (C2) server. It specifically looks for connections to known exfiltration paths associated with screen monitoring or video uploads within 30 minutes of minicap process activity, effectively identifying surveillance that bypasses Android's MediaProjection consent mechanism.
Detects the use of the 'getevent' command by a shell process to read raw touch input data from '/dev/input/event*'. This behavior is associated with Android malware attempting to capture user interaction or credentials by monitoring touch events.
Detects mobile malware, specifically the RatHat Android malware, attempting to display unauthorized overlay windows over legitimate banking and financial applications to harvest user credentials via WebView components.
This rule detects suspicious activity where a node.exe process, often associated with a node-pty terminal emulation, launches common Windows command-line shells (cmd.exe, powershell.exe) from specific file paths or directories. This behavior is indicative of a Node.js-based Remote Access Trojan (RAT) or shell spawning mechanism being used to establish command and control or persistence on a Windows host.
