This rule detects instances of 'javaw.exe' executing from unusual directories (e.g., AppData, Temp, Users\Public) while loading a 'jli.dll' file from a related non-standard path, or simultaneously being associated with a scheduled task execution involving 'GlobalTellurSync'. This behavior is indicative of potential DLL side-loading or a persistence mechanism where a legitimate Java executable is repurposed to run malicious code.

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 rule identifies potential activity related to the Kothamine malware by monitoring for specific file hashes associated with the malware in process and file execution events, as well as network connections to a specific malicious GitHub repository path used for payload delivery.

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.

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.

Hunts telemetry for published NeedyMantis indicators: three known SHA-256 hashes (WinSparkle.dll first-stage loader and its encrypted archive, plus the older libcurl archive), the C2 domain corp.tripswithengine[.]com, and the C2 URL path /library/zip/ on that domain. Domain/URL matching parses the actual host out of RemoteUrl and requires an EXACT match (not substring 'has/contains'), so a different domain that merely contains 'corp.tripswithengine.com' as a suffix of a longer label (e.g. 'notcorp.tripswithengine.com') or as a prefix of an unrelated domain (e.g. 'corp.tripswithengine.com.evil.net') cannot match. No malicious IP address has been published for this campaign, so IP-based matching is intentionally not included.

This rule monitors for known malicious file hashes, command and control (C2) domains, and specific download URLs associated with identified threats. It correlates these indicators across process execution, file activity, and network connection logs to identify potential compromises or malicious activity related to the aware-cr1 infrastructure.

Detects persistence attempts using common Windows auto-start registry keys or scheduled tasks where the initiating process is unsigned or has an invalid signature. The rule focuses on binaries executing from suspicious, user-writable directories (e.g., Temp, AppData, Downloads) and specifically targets persistence mechanisms involving the 'SecurityHealthService.exe' filename.

This rule detects known-malicious activity associated with Warlock ransomware and the ToolShell malware campaign (linked to Storm-2603). It monitors for process, file, and image-load events matching identified malicious file hashes, as well as network connection attempts to known malicious domains and URLs. It also includes monitoring for traffic to 'oastify.com', a domain commonly used for Burp Collaborator, which requires correlation with other indicators to confirm malicious intent.

This rule monitors for indicators of compromise (IOCs) associated with the Lunex Malware-as-a-Service (MaaS) campaign. It aggregates telemetry from file creation, process execution, and network connections to identify the presence of known malicious hashes, C2 IP addresses, phishing-related domains, and specific payload URLs.

Detects the execution of files ending in '_win64.exe' from 'Perflogs' or 'Documents' directories, which is a known behavior of the Settra ransomware. The rule filters out common system and program file paths to reduce noise.

This rule performs a retrospective sweep for indicators of compromise (IOCs) associated with the 'CSuite' phishing and RMM (Remote Monitoring and Management) campaign. It monitors network, DNS, proxy, email, URL click, and file creation telemetry over the past 24 hours to identify interactions with known-malicious IP addresses, domains, URLs, and file hashes related to the campaign.
