Detects outbound HTTP GET requests to specific GitHub repository paths hosted on raw.githubusercontent.com, which are associated with the Kimsuky threat actor's 'Operation GitPower'. These paths indicate the retrieval of malicious payloads or scripts from adversary-controlled repositories.
Detects a potential post-compromise lateral movement sequence where a host, previously identified as accessing sensitive browser credential files by an unauthorized process, subsequently initiates RDP or WinRM connections to other internal hosts using an account not previously observed performing interactive logons on that source host.
Detects indicators associated with the ChatGPT Custom GPT ClickFix campaign across process, network connection, DNS, and HTTP telemetry: known malicious file hashes, C2 IP addresses, the chattypetty.com domain, and known payload-hosting URLs.
Correlates ARTEX tool artifacts on a device with that device contacting the ARTEX host, xcai.pro, or the DeepSeek API within 24 hours.

Detects outbound HTTP requests to 'letsdiskuss.com' with a URI pattern of '/user/', which is characteristic of the 'STAC4924' loader utilizing a dead-drop resolver for command-and-control communication.
Detects network traffic (DNS, TLS SNI, and HTTP) associated with Wazza phishkit infrastructure, specifically looking for malicious domains like boegl-krysl.eu and coppietersrecherche.eu, as well as Cloudflare workers.dev domains used for beaconing and lures.
Detects potential AiTM or credential harvesting campaigns where a device visits known lure or redirect paths (such as specific domains or workers.dev paths) and subsequently accesses the Microsoft device code authentication page within a 15-minute window.

Detects HTTP responses and TLS client connections associated with Adobe-themed device code phishing lure pages hosted on workers.dev, utilizing specific patterns and keywords such as 'Confirm to open document', 'VERIFICATION CODE', and long hyphenated domain structures.

Detects activity associated with Everest ransomware by matching known file hashes (in DeviceFileEvents/DeviceProcessEvents) and known C2/leak-site domains (in DeviceNetworkEvents).
This rule detects network beaconing behavior consistent with Cobalt Strike's default malleable C2 profiles. It monitors HTTP GET and POST requests for specific URI patterns commonly used by default Cobalt Strike configurations and triggers when multiple such requests are observed from a single host over a 15-minute window.
This rule detects potential post-compromise activity related to a campaign using MSP360-masqueraded installers and ScreenConnect remote access tools. It performs an IOC sweep across device file events for known malicious file hashes (associated with installers and post-compromise utilities) and device network events for connections to known malicious domains used for command and control.
Detects the installation of unauthorized AI-related browser extensions followed by outbound network communication from the browser process to known external AI service API endpoints within one hour. This behavior is indicative of potential data exfiltration via shadow AI tools, bypassing standard enterprise DLP controls.
This rule monitors network traffic from CommonSecurityLog data to detect bidirectional communication between NetScaler appliances and known malicious infrastructure associated with the CVE-2026-88772 campaign, which is indicative of command-and-control activity.
This rule monitors network traffic, DNS queries, and user web clicks to detect interactions with known malicious domains associated with credential harvesting and phishing campaigns, specifically those impersonating security or SSO portals.
Detects the execution of known cloud synchronization utilities like rclone, megasync, or megacmd, which are frequently leveraged by ransomware operators to exfiltrate data to public cloud storage providers. The rule monitors both local process execution with typical command-line arguments and subsequent outbound network connections to common cloud storage domains.
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.
