Detects network connections, process executions, file creations, and image loads associated with the UNC7017 AOMEI supply chain campaign IOC sweep, including specific malicious URLs, domains, IPs, file paths, and hashes.
Detects the AnyDesk Linux service running as root spawning a shell process (sh, bash, dash, zsh) or executing a command associated with the AnyPwn (CVE-2025-27918) post-exploitation behavior.
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.
Detects SSH clients launched with reverse (-R) or dynamic (-D) port
forwarding flags, a hallmark of tunnel establishment used to pivot into internal
networks or expose internal services through a compromised host. The Blinder
Tunnel campaign leverages SSH tunneling to encapsulate C2 and lateral movement
traffic inside an allowed protocol.

Detects post-exploitation activity against Ivanti ICS / Connect Secure
appliances on Windows hosts, where a script host (cmd.exe, powershell.exe, w3wp.exe)
drops a web shell (.aspx/.ashx/.asmx) into the appliance WebRoot or reaches into the
CredentialStore / system binaries. These behaviors are the hallmark of attackers
converting an authenticated file-write or SSRF into persistent remote code execution
and credential theft on edge devices.

Detects network connections, process command-line executions, and email URL info matching known APT28 (Swallowtail, HOOKEDGE, LegionRelay) indicators of compromise, including specific IP addresses and GUIDs.
Detects the usage of command-line flags in AI coding assistant CLIs (such as Claude Code, Amazon Q CLI, and others) that intentionally skip security permissions, bypass approvals, or disable sandbox protections. The rule identifies potential developer activity that may inadvertently reduce the security posture of the development environment.
Detects instances where package managers (pacman, makepkg, yay, paru) or their children spawn a root shell that downloads and executes external scripts via curl or wget.
Detects the sequential relationship of data staging using tools like WinRAR and subsequent exfiltration using tools like Rclone, WinSCP, or FileZilla on a single host within a 24-hour window.
Detects PowerShell processes spawned by common managed file transfer (MFT) or web service processes (such as Serv-U, GoAnywhere, MOVEit, Cleo, Tomcat, etc.) performing remote system discovery or ingress tool transfer activities.
Detects network connections, process executions, file creations, and image loads associated with the UNC7017 AOMEI supply chain campaign IOC sweep, including specific malicious URLs, domains, IPs, file paths, and hashes.
Detects the execution of archiving utilities (7z, rar, tar, or Compress-Archive) targeting configuration directories of AI coding assistants such as Claude, Codex, Cursor, and Gemini.
Detects a sequence of events indicative of Bring Your Own Vulnerable Driver (BYOVD) attacks or security control impairment. It monitors for the loading of a rare driver (seen on 3 or fewer hosts), accompanied by either the creation of a kernel service or defense tampering activities such as disabling security monitoring or stopping security-related services.
Sweeps network, process command-line and URL-click telemetry for the Kimsuky payload C2 domain and its subdomains using an anchored match, which avoids lookalike or suffix-matching domains.
Detects suspicious command-line execution patterns involving 'ccmpwn', coercing features, or manipulation of Configuration Manager configuration files such as SCNotification.exe.config.
The following analytic identifies the use of ping commands as a delay or sleep mechanism within batch-style command execution.
It leverages process creation telemetry from Endpoint Detection and Response (EDR) agents and examines process and parent process command-line fields for ping commands that specify a count and are chained with additional commands using command separators or redirection operators.
While execution of the command may generate individual process creation events, such as a separate ping.exe process, this analytic specifically focuses on the original command string passed to a command interpreter, such as cmd.exe /c, that combines the ping-based delay with subsequent command execution.
Adversaries may use ping as an alternative to explicit sleep or timeout commands to introduce execution delays, potentially evading automated analysis, sandboxing, or behavior-based detection.
Because ping is commonly used for legitimate network troubleshooting, findings should be reviewed in the context of the complete command line, parent process, user, and commands executed before or after the delay.

Detects process creation events where common Office applications (Word, Excel, PowerPoint, Outlook) or archive/reader utilities (Acrobat, WinRAR, 7-Zip) act as the parent process to command-line interpreters, scripting engines, or administrative tools (such as cmd, powershell, wscript, cscript, mshta, rundll32, and others). This behavior is commonly associated with phishing attacks, macro execution, or exploitation of file formats leading to code execution.
Detects usage of vssadmin or wmic to delete Volume Shadow Copies
as observed in The Gentlemen ransomware operations to prevent system recovery
before encryption deployment.

Detects the odbcconf LOLBin delivery step assessed for the MuddyWater-linked PatchAgent chain: 'odbcconf /f cloud.rsp' launched from a PatchAgent working directory, typically via a ClickFix lure (explorer -> conhost --headless -> cmd -> odbcconf) fetching the response file over WebDAV. odbcconf executing a .rsp response file is rare in legitimate use and is high-fidelity when paired with WebDAV or a user-writable working directory.
Detects msiexec.exe executing an MSI package named update_ms.msi
staged in ProgramData. Chaos ransomware disguises this installer's properties
and filename to impersonate a legitimate Windows Update package. On execution,
a custom action (CA_Run_EA2AEBC3) loads an embedded DLL (Bin_lib_EA2AEBC3,
lib.dll) directly into memory, deploying the msaRAT payload. This rule sees
the installer execution only; the in-memory module load is not observed here
and would need a separate PROCESS_MODULE_LOAD rule.

Detects use of wmic to add Microsoft Defender scan exclusions via the
MSFT_MpPreference WMI class, targeting a program-files path and executable named to
impersonate Windows Defender. HoneyMyte (Mustang Panda) ran this exact wmic invocation
before deploying the CoolClient backdoor to a fake "Microsoft\Windows Defender"
directory, excluding both the folder and the renamed sideloader defender.exe from
scanning.
