Sweeps endpoint telemetry for known UAC-0099 MATCHBOIL/LONEPAGE indicators: SHA256 hashes, C2 IPs, C2 domains (including subdomains), and payload/C2 URLs. Matches are limited to public outbound connections, Defender self-activity is excluded from file hits, and repeat hits are collapsed to one row per device and indicator. The lists are a subset of the 142 IOCs in the source report.
This analytic detects the usage of the Utility osascript on a macOS device initiated a network connection lasting longer than 10 minutes (600 seconds).
Adversaries may abuse osascript and AppleScript shell execution to establish long-lived command-and-control or remote connections.

Detects endpoint connections to known DarkSword/Coruna exploit-host and C2 infrastructure. The shared AWS IP is only matched on C2 ports 8881/8882 to reduce collateral hits.

Performs an IOC sweep for a known XMRig cryptojacking campaign exploiting a REDCap vulnerability (CVE-2026-90817), detecting matching network connections, file hashes, and process activities across endpoints.
This rule monitors endpoint telemetry (DNS queries, network connections, file creation, and process execution) to identify matches against a predefined list of known malicious indicators, including IP addresses, domains, and file hashes (SHA256). The rule differentiates between confirmed malicious activity and low-confidence indicators, providing a prioritized view of potential threats.
Detects the handshake process for Blackwood/Chisel reverse SOCKS5 or TCP-over-HTTP tunneling to a known malicious Iranian-hosted C2 IP address. The detection matches specific HTTP headers used by the Chisel tool during its initialization phase.
Detects the AdFection multi-stage infection chain where a device sequentially contacts advertising infrastructure, Candiru validator servers, exploit servers, and Candiru Command and Control domains within a short time window.

Detects historical network connections, URL clicks, browser launches, email URLs, and process command lines associated with Wazza phishkit infrastructure IOCs including boegl-krysl.eu, coppietersrecherche.eu, and beacon-surge-sync.workers.dev.

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 detects indicator of compromise (IOC) sweep events associated with the AhsayCBS campaign (CVE-2026-105133 and CVE-2026-105134) involving XMRig cryptominer activity. It checks for specific file and process SHA256 hashes, remote IP addresses, and domain connections related to known mining pools or attacker infrastructure using Sentinel Device tables.

IOC sweep for ARTEX campaign indicators: C2 host, nine proxy IPs, xcai.pro and its subdomains, and the CLAUDE.md URL across Defender, CEF/firewall, DNS and Entra sign-in telemetry. Domains match on exact host or subdomain only, connection types are limited to real connection events, and sign-ins are limited to successes and credential failures.
Detects indicators of compromise associated with malicious Firefox wallet-clone extensions (Rabby/OKX clones) by checking for known file hashes, extension file names in Firefox profile directories, and network connections to known C2 domains and workers.dev subdomains.

Detects the handshake process for Blackwood/Chisel reverse SOCKS5 or TCP-over-HTTP tunneling to a known malicious Iranian-hosted C2 IP address. The detection matches specific HTTP headers used by the Chisel tool during its initialization phase.
Detects network connections to known Indicators of Compromise (IOCs) associated with the TraderTraitor campaign, including trojanized Terraform providers (FLATROOF/ROOFDECK malware families) using specific domains and URL paths.
Detects network activity associated with the TA419 threat group's 'Frameless' Browser-in-the-Browser (BitB) Adversary-in-the-Middle (AitM) phishing campaign. The rules identify unauthorized OAuth2 authorization requests to non-Microsoft hosts that match known malicious client IDs, the delivery of BitB overlay scripts, and the subsequent execution of malicious scripts correlated with OneDrive-themed lookalike redirects, indicating a credential theft attempt.
