Detects indicators of active exploitation or malicious activity targeting the Flowise application. The rule triggers on the creation of a 'flowise_marker.txt' file, the spawning of node processes with suspicious command-line flags ('--require', 'node_options') potentially intended to bypass security controls, and the execution of unexpected shell or scripting processes (cmd, bash, python, etc.) by a Flowise process.

Detects execution of MyBB exploitation scripts, specifically targeting the 'mybb_limited_acp_to_admin' PoC, or evidence of a web server process (PHP) spawning suspicious shell or interpreter child processes, suggesting post-exploitation activity on a MyBB platform.

This rule monitors for the execution of known exploit scripts targeting MyBB forum software. It specifically detects the use of 'mybb_limited_acp_to_admin.py', as well as Python and PHP processes executing command lines that contain indicators of MyBB administrative control panel (ACP) exploitation, such as unauthorized user creation with administrator privileges (gid=4).

Detects execution of specific scripts or suspicious child processes indicative of a MyBB 'limited_acp_to_admin' exploit attempt. This rule looks for known script names related to the PoC and suspicious process lineage where a PHP web server process spawns command shells or scripting interpreters commonly used in post-exploitation activities.

This rule detects the execution of known exploit binaries and proof-of-concept (PoC) tools associated with vulnerabilities in libssh2, as well as anomalous child process spawning from common SSH-related applications (curl, git, php). These behaviors are indicative of exploitation attempts or unauthorized activity related to the libssh2 exploit chain.

Detects signs of active exploitation of the PHP857 vulnerability. The rule identifies suspicious behaviors associated with this RCE, including the spawning of shells by PHP processes, access to sensitive memory maps (/proc/self/) for ASLR bypass, and the creation of specific indicator files or execution of proof-of-concept strings.

Detects network share enumeration activity associated with Akira ransomware pre-deployment reconnaissance. The rule monitors for the execution of PowerShell PowerView cmdlets such as Invoke-ShareFinder, Find-DomainShare, and Get-NetShare, as well as the execution of the SoftPerfect Network Scanner (netscan.exe), including renamed instances staged in the ProgramData directory.

Detects the use of wbadmin.exe to initiate a system backup that targets sensitive Active Directory and registry files (NTDS.dit, SYSTEM, and SECURITY hives) to a local SMB share on the loopback address. This technique is used by threat actors to stage critical credential material for offline extraction and cracking.

Detects Vidar Stealer cloning a browser process (Chrome/Edge/Brave) using NtCreateProcessEx with a NULL SectionHandle to snapshot the browser address space for v20_master_key scanning as part of its Chrome Application-Bound Encryption (ABE) bypass chain.

009
This rule detects attempts to bypass User Account Control (UAC) using specific Windows executables (eventviewer.exe, fodhelper.exe, computerdefaults.exe, slui.exe) initiated by cmd.exe or powershell.exe. The rule specifically looks for these executables being run from non-standard system directories, indicating a potential UAC bypass technique often observed after an initial compromise, such as via RDP.

Detects the creation, execution, or deletion of Windows scheduled tasks using 'Mozilla' task names (specifically '\Mozilla\UpdateTask' or '\Mozilla\ElevateTask'). The rule identifies tasks created with SYSTEM privileges and 'ONSTART' triggers via schtasks.exe, as well as associated administrative commands to run or delete these tasks, and correlates these with Security Event ID 4698.

This rule detects a multi-stage attack sequence where a user is subjected to a 'spam bomb' (large volume of inbound emails in a short time), followed by an external Microsoft Teams contact, and concluding with the execution of legitimate remote support tools (Quick Assist or MSRA) on the victim's endpoint, which is a common pattern for social engineering and technical support fraud.

105
Detects privilege escalation events (assigning special privileges or executing privileged operations) occurring on a host shortly after the execution of legitimate remote support tools such as Quick Assist or msra.exe. This pattern is consistent with social engineering campaigns where attackers gain remote access via support tools and then perform local privilege escalation.

Detects the execution of forced system shutdown commands (shutdown -s -t 0) initiated via cmd.exe or PowerShell. This behavior is often observed in post-compromise scenarios, including the TonRAT campaign, to disrupt system availability.

Detects the execution of a PowerShell script named 'cap.ps1' using common obfuscation and evasion flags including '-windowstyle hidden' and '-executionpolicy bypass'. This pattern is frequently used by adversaries to execute malicious scripts while minimizing user visibility and bypassing standard security policy restrictions.

Detects the execution of VBScript files (via wscript.exe or cscript.exe) where the parent process is a common web browser (Chrome, Firefox, Edge, or IE). This pattern is frequently indicative of a drive-by download or social engineering attack where a user is tricked into executing a malicious script originating from a web-based context.

Detects the creation of the 'MixedSvc' Windows service, which is used by DcRAT malware in Operation DragonReturn for persistence. The malware masquerades as 'Windows Mixed Reality Service' and sets the service's binPath to 'C:\Program Files\Windows Media Player\Mixed Reality.exe'.

This rule detects a sequence of events indicative of ransomware deployment following a successful Remote Desktop Protocol (RDP) connection. Specifically, it looks for an inbound RDP connection (RemotePort 3389) to a device, followed within 60 minutes by the execution of known ransomware executables ('servertool.exe', 'encrypt.exe') on the same device. This pattern suggests an attacker gaining initial access or moving laterally via RDP and then deploying ransomware.

Detects a browser launching cmd.exe or PowerShell immediately after a user visits or downloads content presented as an AI coding assistant installer. This rule specifically looks for process creation events where a browser (Chrome, Edge, Firefox) is the parent process, and the child process is a command shell (cmd.exe, powershell.exe, pwsh.exe), with the command line containing keywords related to 'claude', 'install', 'setup', 'copy paste', 'mshta', or 'download'.
