Signatures

Antivirus / Scanner detection for submitted sample
Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for submitted file
Suricata IDS alerts 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
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)
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)
IP address seen in connection with other malware
Internet Provider seen in connection with other malware
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
