Detects shadow copy destruction and recovery feature tampering used
by Akira and other ransomware families to prevent victims from restoring data.
Covers vssadmin / wmic shadowcopy deletion, wbadmin catalog deletion and
bcdedit recovery-disabling commands executed from the command line.

Alerts whenever a default SAP administrative account (e.g., SAP*, DDIC, TMSADM) logs into the system. These accounts should be locked and used only for emergency 'break-glass' scenarios
Detects endpoint network connections made to known staging IP addresses often associated with data exfiltration or staging activities.
Detects the execution of NetSupport Manager client binaries (client32.exe or pcictlui.exe) from user-writable directories such as AppData, ProgramData, or Public folders, optionally spawned by script loaders or command interpreters.
Detects repeated Ollama warning-level network errors, such as DNS lookup failures, TCP connection issues, or host resolution problems. These events can indicate a connectivity issue and warrant investigation, but do not by themselves establish unauthorized access or reconnaissance.
Detects AppInit DLL registry modifications referencing DLLs located in user-writable directories (such as AppData, Temp, Users\Public, or Downloads), which may indicate adversary persistence or process injection configuration.
Detects service-initiated processes using cryptocurrency mining algorithms, pool configurations, or miner-specific execution parameters.
Detects script execution (such as wscript, cscript, mshta) spawned from a shell parent process (like explorer.exe or cmd.exe) referencing browser cache files (matching f_* in browser profile directories) or copying scripts to the local Temp directory as t.vbs.
Detects unauthorized access to virtual hard disk (VMDK) files by non-standard processes followed by the creation or modification of sensitive offline credential artifacts such as ntds.dit or SYSTEM hives on the same host within a 2-hour window, indicating potential offline credential theft.
Detects potential defense evasion activity where Windows Defender configurations are modified or disabled, followed closely within 20 minutes by a silent, quiet, or unattended software uninstallation initiated by a script interpreter or command processor on the same device.
Detects the execution of Wireshark or tshark with command-line arguments indicating TLS key logging or packet capture file handling, followed shortly by a crash handler process (WerFault.exe or WerFaultSecure.exe) for the same process.
Detects AI coding assistants and agents (such as Copilot, Cursor, Claude Code, etc.) spawning command-line interpreters (PowerShell, CMD, Node, Bun, Deno) with potential API keys, tokens, or credentials exposed in the process command line.
Detects potential persistence establishment where an AOMEI-related process writes a DLL file to disk, followed by the creation or modification of a Windows service pointing to that same DLL within a 15-minute window.
Detects an AhsayCBS / Tomcat / Java web service process spawning a
command or script interpreter. After exploiting AhsayCBS, attackers executed
shell commands through the dropped webshell to run reconnaissance and download
the XMRig payload. A backup web service should never directly spawn cmd.exe,
powershell.exe, or a Unix shell - this indicates webshell command execution.

This rule detects suspicious driver loading from user-writable paths, kernel driver service creation, disabling of driver signing, loading of Linux kernel modules, and the usage of LD_PRELOAD for rootkit functionality.
Detects execution of Node.js and NPM related commands involving potential supply chain indicators, script execution, or download utilities (such as curl, wget, powershell, or eval) within command lines.
Detects when a web browser (such as Chrome, Edge, Firefox, Internet Explorer, Brave, or Opera) spawns common command interpreters, scripting engines, or Living off the Land Binaries (LOLBins) like cmd, powershell, mshta, rundll32, or certutil. This behavior is often indicative of a drive-by compromise or browser exploitation attempt.
Detects an executable running from the C:\Windows\ directory (excluding known benign applications) that establishes two or more distinct persistence mechanisms within a short timeframe, such as scheduled tasks, registry run keys, or startup folder shortcuts.
Detects the correlation between the loading of known stealer plugin DLLs outside of standard application paths and subsequent process activity accessing credential stores, sensitive files, or executing wireless key recovery commands.
Detects PowerShell processes spawned via shortcut files (lnk) using suspicious command-line parameters that subsequently create both a text file and a Discord-named executable on the same device within a 10-minute window.
Correlates a Webcam.dll image load with VM-detection commands (such as queries for VirtualBox, VMware, vbox, vmtoolsd, Win32_ComputerSystem, or Win32_BIOS) executed by the same RegSvcs.exe process, which is characteristic of XWorm malware behavior.
