Detects a multi-stage process execution chain involving PowerShell: first, a script-based download of remote content, followed by in-memory reflection, and finally, suspicious memory allocation or thread manipulation within the same process context. This pattern is characteristic of fileless malware execution chains designed to evade disk-based detection.
Matches distinctive DragonForce TURN/MQTT campaign artifact filenames only when combined with byte-level markers unique to the malware (PE structure, TURN/MQTT C2 infrastructure strings, or the loader's pipe-caret-pipe thread-trigger byte pattern), to avoid false positives on unrelated benign files sharing these names.
Detects anomalous execution of PowerShell commands spawned by processes identified as 'javaw.exe' or 'GlobalTellurSync.exe' (associated with DragonForce backdoor activity). The detection focuses on instances where these processes launch from non-standard user-writable directories (e.g., AppData, Temp) and execute PowerShell commands that contain obfuscated arguments or payloads, while excluding standard scheduled task invocations.

This rule performs a retrospective sweep across Microsoft Defender XDR data sources (DeviceFileEvents, DeviceProcessEvents, DeviceNetworkEvents, and EmailEvents) to identify activity associated with the Star Blizzard (COLDRIVER) campaign. It monitors for specific file hashes, file names, known C2 IP addresses and domains, malicious URL patterns, and known phishing email sender addresses identified in threat intelligence reporting.
Detects the execution of control.exe with suspicious command-line arguments involving WebDAV paths (DavWWWRoot) and file extensions like .cpl or .dll, initiated by Windows task-related processes (svchost, taskeng, schtasks). This pattern is indicative of potential malicious payload loading or proxy execution where a scheduled task is used to trigger a secondary malicious component.

This pattern is indicative of potential malicious payload loading or proxy execution where a scheduled task is used to trigger a secondary malicious component.
Detects the execution of 'Silent XMR Miner Builder.exe' followed by the spawning of common compilers (e.g., csc.exe, gcc.exe, donut.exe), which is indicative of a developer tool being used to compile and build a cryptocurrency mining payload.
Detects instances where a legitimate Remote Monitoring and Management (RMM) agent (MSP360 or Faronics) is used to execute PowerShell commands that silently install ScreenConnect (ConnectWise Control) MSI packages within a 10-minute window. This behavior is indicative of an adversary abusing administrative tools for lateral movement or persistence.
Detects instances where a legitimate Remote Monitoring and Management (RMM) agent (MSP360 or Faronics) is used to execute PowerShell commands that silently install ScreenConnect (ConnectWise Control) MSI packages within a 10-minute window. This behavior is indicative of an adversary abusing administrative tools for lateral movement or persistence.
This rule detects the execution of potentially malicious binaries masquerading as legitimate Windows utilities (e.g., Windows Update, Defender, or Phone Link) from within a ScreenConnect temporary directory. This behavior is indicative of a phishing attack where an adversary uses remote access tools to stage and execute malicious payloads on a victim's system.
This rule performs a sweep across device file and network events for indicators of compromise (IOCs) associated with the UAT-11587/Antino campaign. It detects malicious file hashes, specific C2 domain connections, and known lure URLs (HTA/WSF) identified by Cisco Talos.

Detects activity associated with the MALFEX npm supply-chain campaign (also known as Overlord/movinlike). This rule performs a sweep for known malicious file hashes, suspicious process command lines, outbound network connections to malicious domains or IPs, and email communications from identified adversary-controlled accounts.
Detects the installation or execution of known MALFEX malicious packages via npm or Node.js, which are used as entry points for polyglot or disguised payload delivery.
Detects command-line activity indicative of attempts to perform a DCSync attack, a method used to simulate the replication process of a Domain Controller to extract sensitive Active Directory credentials, including password hashes, using tools like Mimikatz or DSInternals.
Detects the creation of a scheduled task using 'schtasks.exe' that involves suspicious command-line patterns, specifically tasks pointing to potentially volatile directories (temp, appdata, programdata) or tasks executing PowerShell/CMD with common obfuscation/execution arguments such as encoded commands, hidden window styles, or base64 decoding.
This rule detects potential lateral movement activity by identifying the execution of PsExec service components or common lateral movement tools (PsExec, WMIC, CMD) interacting with Windows administrative shares (via UNC paths or specific network ports 135, 139, 445). It specifically looks for process creation events associated with these tools and network activity indicative of remote administration. Legitimate administrative tools signed by Microsoft or known management software (SolarWinds, Tanium, Ivanti, IBM BigFix) are explicitly excluded.
This rule detects persistence mechanisms involving the modification of Windows Registry 'Run' keys or the addition of executable/script files to the Windows Startup folder. It flags suspicious file types (vbs, js, hta, ps1, lnk) or the usage of common living-off-the-land binaries (wscript, cscript, powershell, mshta) when interacting with these persistence locations, while filtering out known benign processes like trustedinstaller.exe and explorer.exe.
Detects the execution of PowerShell processes using suspicious command-line flags, encoding, or built-in .NET network download methods (e.g., IEX, Net.WebClient, DownloadString). The rule excludes signed PowerShell binaries and common system management tools like SCCM or monitoring agents to reduce false positives.
