Detects instances where AI-based coding or agent-driven tools (e.g., Cursor, Claude Code, AutoGPT) perform suspicious file archiving/packaging activities followed by network egress to unauthorized or known exfiltration-prone services. This helps identify potential data exfiltration by AI agents or compromised development environments.
Detects the loading of a known malicious 7z.dll file within the 'Traiolx Custom Utils' directory. This behavior is indicative of DLL sideloading used by LegionLoader to achieve code execution under the guise of a legitimate application.

Detects the presence of a suspicious or known malicious 'Normaliz.dll' file located within the 'Traiolx Custom Utils' directory, indicative of a DLL sideloading attempt.
Detects the creation of temporary files with names starting with 'MSI' and ending in '.tmp' within the system's temporary directory. Legitimate installations typically perform these actions via the 'msiexec.exe' process; therefore, files created by other processes may indicate suspicious payload staging or activity by malware attempting to masquerade as MSI installer components.
Detects the creation of files with the .ent extension within the Microsoft Internet Explorer directory. This behavior is associated with the NarwhalRAT malware, which uses this specific file extension and location to store AES-encrypted configuration files, likely for persistence or subsequent execution by the malware.
This rule detects the creation of executable files (.exe or .dll) within the 'C:\Windows\SysWOW64\' directory by processes other than trusted Windows OS installation or servicing components. This activity is indicative of potential malware staging, side-loading, or persistence mechanisms where an adversary drops malicious payloads into a trusted system directory to evade detection.
Detects UNC6240 PSEMHUB.war web shell/tunnel/trojanized installer artifacts by distinctive content markers (x.jsp, u.jsp, tunnel.jsp/jspx, Ple64.exe)
Detects UNC6240 PSEMHUB.war web shell/tunnel/trojanized installer artifacts by distinctive content markers (x.jsp, u.jsp, tunnel.jsp/jspx, Ple64.exe)
Detects Neo-reGeorg tunnel.jsp/tunnel.jspx servlets used by UNC6240 to establish SOCKS5-over-HTTP(S) tunneling from compromised PeopleSoft PSEMHUB.war hosts
Detects a multi-stage infection chain associated with RedFlick, involving the delivery of VHDX files or PDF attachments. The rule correlates malicious activities such as SSH-based tool download (using PermitLocalCommand), PowerShell-based PDF decoding/extraction, PowerShell VHDX disk mounting, and silent MSI installation from remote URLs. It monitors for these activities within user-writable directories like Downloads or Temp.

This rule detects instances where the Faronics Deploy Agent process initiates the installation or download of ScreenConnect remote access software via PowerShell or the Windows Installer (msiexec.exe). This pattern is often indicative of authorized RMM deployment, but it is also a common tactic for adversaries to establish persistent remote access to endpoints.

Detects the download of a masqueraded MSP360 RMM v2.5.0.67 installer to the Downloads folder. The rule identifies files matching specific naming conventions, including generated GUIDs, or known malicious hashes, originating from common cloud storage providers often abused by threat actors.

This rule detects a suspicious sequence of events where a process named RMM.Agent.exe executes a PowerShell command to download and install 'ClientSetup.msi' via msiexec.exe, followed closely by the execution of a ScreenConnect client process. This chain of activity is consistent with unauthorized or potentially malicious deployment of ScreenConnect (ConnectWise Control) for persistent remote access.

This chain of activity is consistent with unauthorized or potentially malicious deployment of ScreenConnect (ConnectWise Control) for persistent remote access.
This rule detects a sequence of suspicious activities indicative of malicious driver installation. It identifies the creation of an irregularly named .sys file in temp directories, the use of curl.exe to retrieve symbols for a potentially malicious driver, and the subsequent registration/start of that driver as a Windows system service.
