Detects a suspected ClickFix infection sequence associated with Psychedelic Stealer. The rule identifies a user navigating to known malicious lure pages (often mimicking Cloudflare CAPTCHAs) followed shortly by the Windows Run dialog (explorer.exe) initiating msiexec.exe to execute a remote MSI file.
This rule detects the execution, file presence, or driver loading associated with 'EDRKiller' and 'WarsawKiller', which are malicious tools used to terminate or disable endpoint security products.

Detects the initialization of known-malicious Terraform providers (dockerd) followed within one hour by the execution of a 'go run' process from the .terraform directory. This pattern is indicative of a supply chain compromise where an adversary leverages a typosquatted or malicious Terraform provider to facilitate the execution of a secondary payload.
Detects the installation of machine learning or AI software dependencies (pip, conda, npm, poetry) that either pull from unauthorized registries or match known malicious/typosquatting naming patterns (e.g., LiteLLM supply-chain compromise). The rule also monitors for newly published packages that have been flagged as suspicious.
Detects attempts by AI agent code-interpreter or sandbox processes to break out of their containerized environment. The rule monitors for the execution of common container escape techniques, such as namespace manipulation (nsenter, unshare), mounting host filesystems, accessing sensitive host devices like /dev/kmsg or /dev/mem, or referencing host-level paths from within an isolated AI agent execution process.
Experimental behavioral hunt for a Java process directly spawning a root-owned shell or selected command-line utility on explicitly inventoried ISE devices. Potential post-exploitation signal relevant to ISE Java RCE investigations. It does not prove Java deserialization or identify CVE-2026-20307/20211, and requires verified appliance process telemetry.
This rule detects the execution of common Windows administration utilities (vssadmin.exe, wmic.exe, wbadmin.exe, bcdedit.exe) being used to delete Volume Shadow Copies, backup catalogs, or modify boot configuration data to disable automatic recovery. These actions are frequently performed by ransomware to prevent data restoration.
Detects the execution of suspicious child processes (e.g., cmd.exe, powershell.exe, bash, wget) spawned by processes associated with public-facing appliances like Fortinet SSL-VPN, Veeam Backup & Replication, Citrix ADC, and cPanel/WHM. This behavior is often indicative of exploitation of public-facing applications (T1190) for initial access, frequently associated with ransomware actors targeting unpatched infrastructure.
Detects the execution of suspicious child processes (e.g., cmd.exe, powershell.exe, bash, wget) spawned by processes associated with public-facing appliances like Fortinet SSL-VPN, Veeam Backup & Replication, Citrix ADC, and cPanel/WHM. This behavior is often indicative of exploitation of public-facing applications (T1190) for initial access, frequently associated with ransomware actors targeting unpatched infrastructure.
Detects persistence attempts via Windows Registry run keys and Startup folders. The rule identifies suspicious modifications to run/runonce registry keys involving common user-writable paths (e.g., Temp, AppData) or the execution of PowerShell commands with common obfuscation flags (e.g., -enc). Additionally, it detects the creation of executable files (.lnk, .ps1, .vbs, .bat) within user Startup folders.
This rule detects the deployment of suspicious executables or scripts (e.g., .exe, .bat, .ps1, .vbs) via Group Policy (GPO) paths or through GPO-related processes like gpscript.exe and gpupdate.exe. This activity is consistent with using GPOs to distribute and execute malicious binaries across a domain, often a precursor to ransomware deployment.
Detects the deletion of Windows Volume Shadow Copies using vssadmin.exe, wmic.exe, or PowerShell (WMI/CIM objects). This activity is commonly used by ransomware to prevent local data recovery by destroying shadow copy backups before encryption.
Detects the use of command-line tools like s5cmd or aws-cli to synchronize or copy data to an Amazon S3 bucket. The rule identifies suspicious patterns by looking for specific transfer commands combined with recursive or high-concurrency flags that indicate mass data movement often associated with exfiltration.
Detects usage of the 'gem' command (install, build, push, publish) that includes naming patterns or specific command strings associated with the GemStuffer supply chain compromise campaign. This targets attempts to introduce malicious dependencies into the environment using RubyGems.
Detects indicators of compromise related to the TraderTraitor (KelpDAO) threat actor, including specific file hashes, malicious process paths, C2 network infrastructure (IPs and domains), and malicious TLS certificates. The rule uses filename-path matching to reduce noise from legitimate macOS binaries.
Detects the use of 'terraform init' where the command line arguments reference known typosquatted HashiCorp registry domains. This behavior is indicative of a supply chain attack attempting to pull malicious providers or modules from an adversary-controlled source.
Detects Node.js processes executing suspicious command lines that involve fetching and executing remote JavaScript code. This behavior is indicative of a loader or downloader script commonly used to pull and evaluate malicious payloads at runtime, specifically referencing indicators associated with 'GHAPPIER'.
This rule detects potential staging activity for ClickFix or Vidar malware campaigns. It identifies the creation of files or folders in directories mimicking Windows Diagnostics infrastructure (WDI) or known payload paths, correlated with the execution of suspicious PowerShell commands or archive-related utilities within a 30-minute window on the same device.
This rule detects malicious activity related to the exploitation of MpDlpService.exe. It looks for the execution or presence of known malicious file hashes associated with this threat, including a P-stage script, payload files, and a malicious mpclient.dll. Additionally, it identifies instances where the legitimate MpDlpService.exe binary is executed from a non-standard, suspicious directory, which is a common indicator of side-loading or persistence techniques.
Detects the execution of WinRAR utilities (WinRAR.exe, Rar.exe) with suspicious command-line arguments typically associated with data staging, archiving, or encryption. The rule filters out legitimate WinRAR installations and only triggers when the process is spawned by a script interpreter (e.g., PowerShell, CMD) or operates within sensitive file paths (e.g., Users, Shares, Finance, HR, Backup).
