Detects the creation of scheduled tasks using schtasks.exe initiated by command shells where the task command points to files residing in non-standard or user-writable directories such as \Users\Public\, \PerfLogs\, or \ProgramData\. This pattern is frequently utilized by malware loaders like SocGholish, GootLoader, and various ransomware strains to achieve persistence following initial compromise.
Detects instances where the MSBuild.exe process is subjected to image replacement or tampering, a behavior often associated with process hollowing or malicious code injection techniques aimed at evading security defenses by masquerading as a legitimate developer utility.
Detects the execution of PowerShell from a shortcut (.lnk) file, particularly when suspicious command-line arguments such as hidden windows, encoded commands, or bypass flags are utilized. This pattern is commonly associated with initial access via malicious attachments or shortcut files.
This rule detects potential unauthorized use of MeshAgent RMM software by correlating process execution events (mvtcs.exe, MeshAgent) with network traffic to specific IP addresses identified as associated with Settra command-and-control infrastructure. It specifically filters for MeshAgent activity and validates the threat by requiring an established network connection to known malicious endpoints.
This rule monitors for a variety of indicators associated with malicious activity, including connections to known malicious IP addresses, the presence of specific malicious file hashes or filenames, modifications to Windows system policies (specifically Legal Notice configuration), and changes to Active Directory Group Policy Objects using specified GUIDs.
Detects the execution of PowerShell with hidden flags and encoded commands spawned by a 'conhost.exe' process running in '--headless' mode. This specific process pattern is indicative of the obfuscated execution chain used by LausivLoader.
This rule detects a suspicious sequence of events occurring on a host within a 600-second window: the modification of the Windows Trusted Root Certificate store (via certutil or registry manipulation) followed by the writing of a new executable file. This behavior is indicative of an adversary establishing persistence or preparing to bypass security controls by installing a malicious CA certificate and dropping a packed binary.
This rule detects instances where the Terraform CLI tool connects to suspected lookalike domains associated with supply chain compromise attempts (e.g., hashicorp-aws[.]com or hashicorp-terraform[.]io) during common initialization or application workflows. It correlates process execution with network connection logs and optionally validates the presence of a related .terraform.lock.hcl file associated with the malicious origin.

The following analytic detects duplicate-handle and query-limited-information access to winlogon.exe from an uncommon or public source path.
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_DUP_HANDLE (0x40) and PROCESS_QUERY_LIMITED_INFORMATION (0x1000).
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_DUP_HANDLE (0x40) and PROCESS_QUERY_LIMITED_INFORMATION (0x1000).
The following analytic detects a process requesting PROCESS_TERMINATE access to Lsass.exe.
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_TERMINATE (0x1).
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_TERMINATE (0x1).
The following analytic detects WMI token impersonation by identifying `wmiprvse.exe` requesting the query, VM, and duplicate-handle rights associated with WMI process access.
It leverages Sysmon EventCode 10 and checks for access masks that combine PROCESS_QUERY_INFORMATION (0x400), PROCESS_QUERY_LIMITED_INFORMATION (0x1000), PROCESS_VM_OPERATION (0x8), PROCESS_VM_READ (0x10), PROCESS_VM_WRITE (0x20), PROCESS_DUP_HANDLE (0x40), and PROCESS_ALL_ACCESS (0x1f3fff).

The following analytic detects executable file formats being created within the Confluence main directory.
This can be indicative of exploitation of the Confluence web services to stage malware.
This won't catch adversaries who modify the output location outside the Confluence directory when exploiting.

Detects Microsoft Office applications (Word, Excel, PowerPoint) spawning common LOLBAS (Living Off the Land Binaries and Scripts) child processes. This behavior is a common indicator of macro-based malware or malicious document exploitation where Office applications are used to execute shell commands or scripts for payload delivery or execution.
Detects instances where Windows Explorer spawns cmd.exe to execute specific batch files (doxc.bat or config.bat), a behavior often associated with Transparent Tribe (APT36) activity involving malicious LNK shortcuts.
Detects the creation of hard links using 'mklink /H' targeting specific paths in ProgramData or linking to specific executable paths in AppData. This behavior is often indicative of adversaries attempting to perform file system manipulation for persistence, defense evasion, or masquerading.
This rule detects the execution of RUSTYMOVE, a tool associated with the Transparent Tribe (APT36) threat group, which is used for propagation via removable media. It monitors for the specific executable 'Automata-20.exe', the presence of specific task-related command line arguments, the dropping of suspicious file paths, and PowerShell-based enumeration of connected USB/removable drives.
Detects the execution of HTSPnew.Exe with specific command-line arguments indicative of KRSID ransomware operations, such as configuration flags for paths, batch processing, and dry-run modes. The use of these flags with this specific executable name is a strong indicator of malicious activity.
Detects the creation of files with the name 'README_KRSID.Txt', which is a hallmark behavior of the KRSID ransomware strain used to leave ransom notes on compromised systems.
Detects ClickFix-style social engineering attacks where users are lured to 'cloudrobots.cloud' and subsequently execute malicious commands via Windows shell tools (cmd, powershell, mshta, etc.). The rule correlates browser network events to a specific domain, subsequent process launches by explorer.exe, and suspicious registry modifications associated with the Windows RunMRU, which is often abused to store and execute commands pasted by victims.
This rule detects the presence of compiled Python 3.10 bytecode (.pyc) files that have been renamed to or disguised with a .cat extension. It specifically looks for the 'settingenv.cat' file associated with the Chinotto backdoor, as well as associated C2 URL patterns or command-line artifacts indicative of its download and execution chain.
