Detects the use of dsquery.exe to enumerate users in Active Directory. This command-line utility is often used by attackers for reconnaissance to gather information about domain users.
This rule detects when Microsoft Office applications (Word, Excel, PowerPoint) create INI files within the `C:\ProgramData\` directory. This behavior can be indicative of malicious activity, such as macro-enabled documents dropping configuration files or payloads, or other forms of malware attempting to establish persistence or store data in a less scrutinized location.
Detects instances where msbuild.exe is used to execute project files (.proj) from suspicious or uncommon directories. Adversaries may abuse MSBuild to proxy execution of malicious code, often placing these project files in temporary or public user directories to evade detection.
This rule detects network connections from devices to a predefined list of known malicious domains. It identifies attempts by internal systems to communicate with command and control servers, phishing sites, or other infrastructure associated with threat actors.
This rule detects network connections or URL click events to a list of domains known to be associated with phishing or malware distribution. The rule specifically looks for connections to these domains that also contain certain path segments like '/wlc/', '/load/', or '/success/', which are often indicative of malicious activity or payload delivery. It also broadly checks for any URL click events containing these suspicious domains.
This rule detects inbound emails that appear to be Microsoft Teams invitations but contain suspicious keywords in the subject line related to financial transactions (invoice, billing, payment, renewal, charge). This could indicate a phishing attempt where adversaries leverage legitimate-looking Microsoft invitation emails to deliver financially themed lures.
Detects DLL side-loading attacks where consent.exe loads known malicious DLLs (version.dll, rtworkq.dll, wmsgapi.dll, and the older msimg32.dll) from non-standard locations. This technique is used by Shanya-packed malware including EDR Killer and CastleRAT to load malicious payloads while appearing as a legitimate Windows UAC process.
Detects the execution of 'conhost.exe' with the '--headless' argument, specifically when initiated by 'pcalua.exe'. This combination has been observed in attacks by the GOLD BLADE threat group for indirect command execution.
A detection triggered on endpoint events where common system binaries (e.g., mshta.exe, powershell.exe, cmd.exe) were launched by user-facing parent processes (explorer.exe, chrome.exe, msedge.exe, firefox.exe, iexplore.exe) and executed suspicious command-lines. The pattern matches the evolving technique used in ClickFix-style campaigns whereby malicious pages dynamically place payloads into the clipboard and prompt users to paste or execute them.
This rule detects suspicious execution of 'RUNDLL32.EXE' with specific command-line arguments. It looks for instances where 'RUNDLL32.EXE' is executed with both a backslash and a comma in the command line, combined with specific DLL names or keywords like 'iamnotarobot.dll', 'checkme.dll', 'machinerie.dll', 'humanCheck', or 'verifyme'. This pattern is often indicative of malicious DLL loading or persistence mechanisms.
