Whitelisted: false
Confidence: 100%

Signatures

Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Snort IDS alert for network traffic
Yara detected XWorm
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code contains potential unpacker
AI detected suspicious sample
C2 URLs / IPs found in malware configuration
Machine Learning detection for sample
Queries sensitive video device information (via WMI, Win32_VideoController, often done to detect virtual machines)
Sample uses string decryption to hide its real strings
Uses known network protocols on non-standard ports
Abnormal high CPU Usage
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to dynamically determine API calls
Contains functionality to query CPU information (cpuid)
Contains functionality to query locales information (e.g. system language)
Contains functionality to read the PEB
Contains functionality which may be used to detect a debugger (GetProcessHeap)
Contains long sleeps (>= 3 min)
Detected TCP or UDP traffic on non-standard ports
Detected potential crypto function
Enables debug privileges
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)
Found potential string decryption / allocating functions
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
