Signatures
Malicious sample detected (through community Yara rule)
Yara detected Emotet
System process connects to network (likely due to code injection or exploit)
Antivirus detection for URL or domain
Multi AV Scanner detection for domain / URL
Multi AV Scanner detection for dropped file
Query firmware table information (likely to detect VMs)
Changes security center settings (notifications, updates, antivirus, firewall)
Suspicious powershell command line found
Suspicious command line found
Powershell drops PE file
Machine Learning detection for dropped file
Hides that the sample has been downloaded from the Internet (zone.identifier)
Queries the volume information (name, serial number etc) of a device
Yara signature match
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Very long cmdline option found, this is very uncommon (may be encrypted or packed)
May sleep (evasive loops) to hinder dynamic analysis
Checks if Antivirus/Antispyware/Firewall program is installed (via WMI)
Uses code obfuscation techniques (call, push, ret)
Creates files inside the system directory
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
Sample execution stops while process was sleeping (likely an evasion)
Found evasive API chain (may stop execution after checking a module file name)
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to dynamically determine API calls
IP address seen in connection with other malware
Downloads executable code via HTTP
Contains long sleeps (>= 3 min)
Enables debug privileges

Drops PE files
Tries to load missing DLLs
Uses a known web browser user agent for HTTP communication
Drops PE files to the windows directory (C:\Windows)
Detected TCP or UDP traffic on non-standard ports
Registers a DLL
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Queries disk information (often used to detect virtual machines)
Found large amount of non-executed APIs
Creates a process in suspended mode (likely to inject code)
