Signatures

Multi AV Scanner detection for submitted file
Yara detected Emotet
System process connects to network (likely due to code injection or exploit)
Antivirus detection for URL or domain
Changes security center settings (notifications, updates, antivirus, firewall)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Queries the volume information (name, serial number etc) of a device
One or more processes crash
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query locales information (e.g. system language)
Deletes files inside the Windows folder
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
Sample execution stops while process was sleeping (likely an evasion)
Found evasive API chain (may stop execution after checking a module file name)
JA3 SSL client fingerprint seen in connection with other malware
Contains functionality to dynamically determine API calls
HTTP GET or POST without a user agent
IP address seen in connection with other malware
AV process strings found (often used to terminate AV products)
PE file contains an invalid checksum
Tries to load missing DLLs
Drops PE files to the windows directory (C:\Windows)
Checks if the current process is being debugged
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)
Creates a process in suspended mode (likely to inject code)
