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 malformed HEIF/HEIC image files with anomalous ftyp/box structure consistent with the libheif memory corruption exploit (CVE-2026-32882) used against Discourse forum image upload endpoints
Detects post-exploitation shell activity spawned from the IIS worker process (w3wp.exe), narrowed to command lines carrying encoded/obfuscated PowerShell flags, remote-download cradles, or basic recon/persistence commands (whoami, certutil, bitsadmin, schtasks, reg add). This reduces noise from benign w3wp.exe-initiated automation while retaining the behavioral pattern seen in the Telerik UI for ASP.NET AJAX unauthenticated RCE chain (webshell/in-memory DLL execution dropping to a shell).
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.
This rule monitors for execution of suspicious files or processes and network communication associated with known malicious indicators (hashes, domains, and IP addresses) typically used by specific threat actors for command and control (C2) and payload delivery.

Detects the execution of PowerShell or Windows Script Host (wscript/cscript) spawned by explorer.exe that utilize hidden window styles and target suspicious filenames or external paths, often indicative of a dropper or malicious script stage.
