Signatures

JScript performs obfuscated calls to suspicious functions
Sigma detected: Powershell launch regsvr32
Yara detected Strela Downloader
Gathers information about network shares
JavaScript source code contains functionality to generate code involving a shell, file or stream
Sigma detected: Suspicious Invoke-WebRequest Execution
Sigma detected: Suspicious Script Execution From Temp Folder
Sigma detected: WScript or CScript Dropper
Suspicious execution chain found
Suspicious powershell command line found
Windows Scripting host checks user region and language preferences
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Wscript starts Powershell (via cmd or directly)
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates files inside the system directory
Found WSH timer for Javascript or VBS script (likely evasive script)
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
Java / VBScript file with very long strings (likely obfuscated code)
May sleep (evasive loops) to hinder dynamic analysis
Queries disk information (often used to detect virtual machines)
Queries the volume information (name, serial number etc) of a device
Sample execution stops while process was sleeping (likely an evasion)
Sigma detected: Cscript/Wscript Potentially Suspicious Child Process
Sigma detected: Potential DLL File Download Via PowerShell Invoke-WebRequest
