Signatures
Found malware configuration
Multi AV Scanner detection for submitted file
Benign windows process drops PE files
Yara detected SmokeLoader
System process connects to network (likely due to code injection or exploit)
Antivirus detection for URL or domain
Multi AV Scanner detection for dropped file
Maps a DLL or memory area into another process
Tries to detect sandboxes and other dynamic analysis tools (process name or module or function)
Machine Learning detection for sample
Injects a PE file into a foreign processes
Checks for kernel code integrity (NtQuerySystemInformation(CodeIntegrityInformation))
Contains functionality to inject code into remote processes
Deletes itself after installation
Machine Learning detection for dropped file
C2 URLs / IPs found in malware configuration
Creates a thread in another existing process (thread injection)
Hides that the sample has been downloaded from the Internet (zone.identifier)
Possible FUD Crypter (malicious underground PE packer) detected
Checks if the current machine is a virtual machine (disk enumeration)
Uses 32bit PE files
Contains functionality to check if a debugger is running (IsDebuggerPresent)
Contains functionality to query locales information (e.g. system language)
May sleep (evasive loops) to hinder dynamic analysis
Uses code obfuscation techniques (call, push, ret)
PE file contains sections with non-standard names
Internet Provider seen in connection with other malware
Detected potential crypto function
Found potential string decryption / allocating functions
Contains functionality to check if a debugger is running (OutputDebugString,GetLastError)
Contains functionality to call native functions
Contains functionality to dynamically determine API calls
IP address seen in connection with other malware
Found a high number of Window / User specific system calls (may be a loop to detect user behavior)

PE file contains strange resources
Drops PE files
Tries to load missing DLLs
Contains functionality to read the PEB
Uses a known web browser user agent for HTTP communication
Checks if the current process is being debugged
Monitors certain registry keys / values for changes (often done to protect autostart functionality)
Creates a process in suspended mode (likely to inject code)
