Signatures

Antivirus detection for URL or domain
Found malware configuration
Malicious sample detected (through community Yara rule)
Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Sigma detected: Drops script at startup location
Yara detected AntiVM3
Yara detected XWorm
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code contains potential unpacker
.NET source code references suspicious native API functions
AI detected suspicious sample
C2 URLs / IPs found in malware configuration
Contains functionality to log keystrokes (.Net Source)
Drops VBS files to the startup folder
Initial sample is a PE file and has a suspicious name
Machine Learning detection for dropped file
Machine Learning detection for sample
Sample uses string decryption to hide its real strings
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Yara detected Costura Assembly Loader
Allocates memory with a write watch (potentially for evading sandboxes)
Checks if the current process is being debugged
Contains long sleeps (>= 3 min)
Creates a process in suspended mode (likely to inject code)
Creates a start menu entry (Start Menu\Programs\Startup)
Detected potential crypto function
Drops PE files
Enables debug privileges
May sleep (evasive loops) to hinder dynamic analysis
One or more processes crash
Queries the volume information (name, serial number etc) of a device
Sample file is different than original file name gathered from version info
Stores files to the Windows start menu directory
Uses 32bit PE files
Uses code obfuscation techniques (call, push, ret)
Yara signature match
