This rule monitors network, file, and process telemetry for matches against a predefined list of malicious IP addresses, domain names, and file hashes. It flags suspicious network connections to known C2 infrastructure and the presence or execution of known malicious files based on SHA256 and SHA1 indicators.
Detects EDRKiller.exe or WarsawKiller.exe binaries and the associated wsftprm.sys BYOVD driver used by The Gentlemen threat actor to terminate security product processes
Detects known file hashes associated with SideCopy/ReverseRAT.
This rule monitors for interactions with known malicious files (by SHA256 hash), connections to confirmed C2 infrastructure (specific IP address and domains), or requests to known malicious URLs. It aggregates indicators across file, process, network, and web browsing telemetry to identify potential threats or compromised systems communicating with known attacker infrastructure.
This rule detects potential malicious activity by monitoring for known indicators of compromise, including specific SHA256 file hashes, a known malicious IP address, and URLs associated with identified threats. The detection spans file creation/execution, network connections, and URL visits to block or alert on interactions with suspicious infrastructure.

The detection spans file creation/execution, network connections, and URL visits to block or alert on interactions with suspicious infrastructure.
This rule monitors for indicators of compromise (IOCs) associated with Operation SideCopy, including specific file hashes, known command-and-control (C2) IP addresses, malicious domains, and URLs. It triggers on file creation, process execution, and network connections matching these known indicators.
This rule correlates multiple telemetry sources (File Events, Certificate Info, Network Events, and DNS Events) to detect known malicious indicators, including specific file hashes, IP addresses, domains, and URLs associated with malicious activity.

This rule detects potential malicious activity by matching file hashes against a known list of malicious indicators and monitoring for suspicious network connections. The network monitoring includes connections to hardcoded malicious IP addresses, specific C2 URLs, and DNS queries for known fallback domains used in malicious infrastructure when the initiating process is not a recognized web browser or wallet application.

Detects the reflectively-loaded SectopRAT .NET payload by its combination of heavy calli (indirect call) opcode usage for control-flow flattening and its characteristic runtime string-decryption helper method used to resolve the C2 IP/port and other obfuscated strings

Detects malicious activity involving the HTS software update mechanism, where the legitimate updater or patch processes are leveraged to download and execute the HTSPnew.exe ransomware payload.
This rule detects the presence of files matching known SHA256 hashes associated with the GhostCode phishing kit. It monitors for these files both in email attachments and on local device filesystems to identify potential delivery and execution of malicious phishing payloads.
Matches known SHA-256 hashes of AvisLoader toolkit components recovered from an exposed staging server: the Windows loader client, UAC-bypass helper, and process-hiding DLL
