Detects a sequence of events where a user clicks a shared link to an AI chatbot conversation followed closely (within 15 minutes) by the execution of potentially malicious processes (mshta, powershell, cmd) that include suspicious command-line patterns indicative of ClickFix-style social engineering.

This rule detects various malicious indicators including known file hashes, IP addresses, domains, and specific URLs associated with threat activity. It consolidates hits from process, file, and network telemetry to alert on potential compromise or communication with identified command-and-control (C2) infrastructure.
This rule detects the loading of a suspicious DLL file named 'active_desktop_render_x64.dll' or the initiation of activity by a process named 'PDF_C2089_20260911100446.exe', which may indicate the execution of malicious code or potential process injection activity.
This rule monitors for various indicators of compromise (IOCs) including malicious domains, IP addresses, specific URI paths, file names, and file hashes. It aggregates telemetry from network, file, process, and certificate events to detect potential threats interacting with known bad infrastructure or executing suspicious files associated with malware campaigns.

It consolidates hits from process, file, and network telemetry to alert on potential compromise or communication with identified command-and-control (C2) infrastructure.
The following analytic identifies the first-time execution of child processes spawned by Zoom (zoom.exe or zoom.us). It leverages Endpoint Detection and Response (EDR) data, specifically monitoring process creation events and comparing them against previously seen child processes. This activity is significant because the execution of unfamiliar child processes by Zoom could indicate malicious exploitation or misuse of the application. If confirmed malicious, this could lead to unauthorized code execution, data exfiltration, or further compromise of the endpoint.

This rule detects the presence of command line artifacts, filenames, and strings associated with the SilverFox malware. These strings indicate the execution of a malicious desktop monitoring component ('active_desktop_launcher.exe') or the use of specific IPC/configuration markers ('@@RAPID_CFG_START@@') characteristic of this threat's tradecraft.
This rule identifies potential infections associated with the MacSync malware family by matching process, file, and network indicators (hashes, malicious domains, and specific payload URLs) against endpoint telemetry. It monitors for execution of known malicious binaries, file creation events, and communication with identified command-and-control infrastructure.
Detects suspicious command execution patterns (such as PowerShell encoded commands, IEX, or cmd.exe) being stored or accessed within the Windows Registry 'TypedPaths' key, which is used by Windows Explorer to track recently accessed paths. Adversaries may attempt to use this location to execute payloads via user-triggered interactions.
Detects network activity associated with the 'ClickFix' social engineering campaign, which commonly targets users with fake error messages to trick them into executing malicious commands. The rule identifies communication with known malicious infrastructure (domains and IP addresses) found in CommonSecurityLog events, while implementing filters to exclude common security scanners and deduplicating per-host alerts.

Detects phishing emails themed around Atlantic Council invitations that contain links attempting to lure users into installing iOS configuration profiles, often associated with malicious backdoors like DarkSword, attributed to the Star Blizzard (G1033) threat group.
