Detects the execution of a specific VBScript file 'Telegram_Private_Call_Session.vbs' via WScript, or its execution when spawned as a child process of MSHTA. This behavior is indicative of an HTA-dropped malicious script attempting to execute.
Detects the execution of wscript.exe as a child process of mshta.exe, specifically when the wscript.exe command line contains references to .vbs or .js files. This behavioral pattern is often associated with malicious HTA files using mshta.exe as a proxy to execute secondary script payloads, a technique commonly leveraged for initial access and execution.
This rule detects potentially malicious activity originating from Microsoft Word (WINWORD.EXE). It monitors for two specific patterns: the creation of script files (.bat, .vbs, .cmd) with GUID-based filenames in non-temp directories, and the creation or execution of files matching known malicious hashes associated with the Hookedge malware family.
Detects the execution of Windows Script Host (WScript.exe or CScript.exe) that creates a file or folder starting with 'Libs_' within the 'C:\Users\Public\' directory. This activity is often associated with attackers staging payloads, configuration files, or tools in publicly writable folders to evade detection.
Detects instances where the Notepad++ executable is launched from a location within the C:\Users\Public\ directory, specifically when the parent process is a Windows scripting engine (wscript.exe or cscript.exe). This pattern is often indicative of an adversary executing a malicious payload staged in a common public directory using script-based wrappers to bypass execution policy or maintain stealth.
Detects instances where the Windows Script Host (wscript.exe) spawns a process to open a PDF file located within the Public user's 'Temp Documents' directory. This behavior is indicative of a potential malware staging or execution attempt where an adversary attempts to open a malicious document from a publicly accessible folder to bypass user suspicion or execute malicious content.
Detects instances where WScript or CScript (Windows Script Host) spawns PowerShell with common obfuscation and persistence flags, specifically executing in a hidden, non-interactive, headless, and encoded command mode. This pattern is commonly used by malicious scripts (e.g., VBScript or JScript) to execute secondary payloads while minimizing visual indicators on the host.
This rule detects potentially malicious activity involving the execution of Node.js scripts initiated by system script proxies (wscript, cscript, msiexec) within specific paths, often associated with subsequent installation of VBScript agents or direct network communication with a known command-and-control IP address.
Detects the creation of a scheduled task via schtasks.exe initiated by wscript.exe or cscript.exe where the task configuration or execution occurs within common user-writable directories (e.g., AppData, Temp, Downloads). The rule specifically flags behavior involving multiple task invocations in a short time frame, which is indicative of persistence mechanisms used by scripts.
Detects the execution of PowerShell or Windows Script Host (wscript/cscript) spawned by explorer.exe that utilize hidden window styles and target suspicious filenames or external paths, often indicative of a dropper or malicious script stage.
Detects the execution of PowerShell or Windows Script Host (wscript/cscript) spawned by explorer.exe that utilize hidden window styles and target suspicious filenames or external paths, often indicative of a dropper or malicious script stage.
Detects the execution of PowerShell or Windows Script Host (wscript/cscript) spawned by explorer.exe that utilize hidden window styles and target suspicious filenames or external paths, often indicative of a dropper or malicious script stage.
Detects the execution of PowerShell or Windows Script Host (wscript/cscript) spawned by explorer.exe that utilize hidden window styles and target suspicious filenames or external paths, often indicative of a dropper or malicious script stage.
Detects the execution of a specific Visual Basic script named 'Telegram_Private_Call_Session.vbs' by Windows scripting utilities (wscript.exe, cscript.exe) or the Microsoft HTML Application host (mshta.exe). This pattern is often associated with the execution of malicious scripts disguised as legitimate communication application components.
Detects the execution of PowerShell with obfuscation-related flags (-NoProfile, -WindowStyle Hidden, -EncodedCommand) initiated by common scripting interpreters (wscript.exe, mshta.exe, cscript.exe). This pattern is often indicative of malicious scripts, such as HTA or VBScript files, attempting to execute encoded PowerShell commands in a high-privilege context.
This rule detects malicious activity by monitoring for specific known indicators, including hashes of malicious files (ProcessRollup2), network connections to known C2 infrastructure (NetworkConnectIP4), and URL clicks (UrlClick) associated with malicious domains or paths. It acts as a multi-stage indicator correlation rule to identify execution or communication with known threats.
Detects the execution of PowerShell with suspicious command-line arguments (headless mode, hidden window, encoded commands) spawned by WScript.exe. This pattern is commonly associated with obfuscated script execution or fileless malware staging.
Detects instances where Windows Explorer (explorer.exe) spawns cmd.exe or wscript.exe to execute batch files (.bat) or scripts with specific filenames. This behavior is often associated with malicious user activity, such as executing payloads disguised as innocuous files triggered via shell interactions.
Detects instances where PowerShell is launched as a child process of WScript.exe or CScript.exe with suspicious command line flags intended to hide window visibility, bypass execution policies, or run in a non-interactive mode. This behavior is frequently used by adversaries to execute obfuscated or malicious scripts while minimizing user awareness.
Detects the execution of a .vbs script file that contains '.pdf' in its filename, followed within 5 minutes by the execution of a WMI query via wscript.exe. This behavior is indicative of a malicious VBScript dropper attempting to perform system discovery using WMI.
Detects the execution of a .vbs script file that contains '.pdf' in its filename, followed within 5 minutes by the execution of a WMI query via wscript.exe. This behavior is indicative of a malicious VBScript dropper attempting to perform system discovery using WMI.
