Multi AV Scanner detection for dropped file
Multi AV Scanner detection for submitted file
Sigma detected: Drops script at startup location
Suricata IDS alerts for network traffic
Yara detected AntiVM3
Yara detected DarkCloud
Yara detected Generic Dropper
.NET source code contains method to dynamically call methods (often used by packers)
.NET source code contains potential unpacker
AI detected suspicious sample
Downloads files with wrong headers with respect to MIME Content-Type
Drops VBS files to the startup folder
Injects a PE file into a foreign processes
Machine Learning detection for dropped file
Machine Learning detection for sample
Sample uses string decryption to hide its real strings
Sigma detected: WScript or CScript Dropper
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Tries to harvest and steal browser information (history, passwords, etc)
Uses the Telegram API (likely for C&C communication)
Windows Scripting host queries suspicious COM object (likely to drop second stage)
Writes or reads registry keys via WMI
Writes to foreign memory regions
Yara detected Costura Assembly Loader
Allocates memory with a write watch (potentially for evading sandboxes)
Contains functionality to call native functions
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
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)
Found inlined nop instructions (likely shell or obfuscated code)
HTTP GET or POST without a user agent
IP address seen in connection with other malware
JA3 SSL client fingerprint seen in connection with other malware
May check the online IP address of the machine
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
Sigma detected: CurrentVersion Autorun Keys Modification
Sigma detected: WSF/JSE/JS/VBA/VBE File Execution Via Cscript/Wscript
Stores files to the Windows start menu directory
Suricata IDS alerts with low severity for network traffic
Uses 32bit PE files
Uses a known web browser user agent for HTTP communication
Uses code obfuscation techniques (call, push, ret)
Yara signature match
